tungsten carbide

For many years, the quality of the corrugated roller cartons has been plagued by domestic enterprises. In December 2001, Shanghai everbright corrugated packaging exhibition, Germany fly wire (Friese) to domestic containing cobalt and tungsten carbide corrugated roll are introduced, and the first to bring home a cardboard-box factory and was the feeling that find everything new and fresh; International corrugated exhibition in Paris in June 2002, during the meeting, internationally renowned corrugated roller Tungsten eletrode launched all kinds of high quality corrugated roll, including tungsten carbide corrugated roll clueless; In late 2002, the domestic several considerable size of the cartons enterprises to start importing tungsten carbide roller; Until February this year, the Shanghai big pine (corrugated roller) industrial co., LTD formally will be tungsten carbide corrugated roll to market, become the first domestic a tungsten carbide manufacturer. Tungsten carbide corrugated roll in the spring breeze can blow through China, see our understanding to the tungsten carbide rollers in the domestic application situation.
By roughly understanding, learned that the tungsten carbide corrugated roll, long life, high precision, after-sales service is also good, so bought a pair of Germany in 2002 fly wire and tungsten carbide. Overall effect, life can be, the only think the price is higher, haining pavilion creek packaging co., LTD., says Mr Zhuo the tungsten carbide roller is equivalent to two pairs of domestic ordinary corrugated roller price. 1 year after the purchase made a grinding. Due to imported from abroad, grinding must be sent to abroad for, not only the cost is higher, and the time is long, become a purchase the tungsten carbide corrugated roll only regret. If tungsten carbide corrugated roll have ability to repair, after-sales service, the overall price down some, prospects should be good.

Tungsten wire carbide material pot mainly for the production of tungsten carbide with a metal bowl and carbon black as raw materials, according to the proportion of a certain mixture again after the ball mill, screening for a quick tungsten carbide material bowl bowl mainly for the production of cemented carbide tungsten carbide. In tungsten carbide, tungsten carbon atoms embedded metal lattice clearance, does not destroy original metal lattice, interstitial solid solution formation, therefore also calls the caulking compounds (or insert). Tungsten carbide can be made of a mixture of tungsten and carbon heating system, the existence of hydrogen and hydrocarbons can accelerate the reaction. If use tungsten preparation of oxygen-containing compounds, vacuum processing products must eventually in 1500 ℃, to remove carbon oxides. Tungsten carbide is suitable for machining under the high temperature , can produce cutting tools, structure materials of kiln, jet engines, gas turbines, nozzle, etc.
With metal tungsten material bowl and carbon black as raw materials, mix in a certain proportion of the mixture into the graphite boat, in feeling or high carbon tube furnace, intermediate frequency electric furnace, carbonization under a certain temperature, then through the ball grinding, screening for a quick tungsten carbide powder.
Chengwei specializing in the production of tungsten carbide, chromium steel, manganese steel, mortar, bowl, mill, grinder sample preparation, vibration mill, crusher, drum machine, muffle furnace, drying oven, etc are widely used in mining, coal, metallurgy, steel, ceramic, X - ray fluorescence analysis and other departments, and LABS.

production technology and technology of tungsten copper alloy

Tungsten eletrode mining lack of total amount control, production is still serious. Advantage for the protection and rational utilization of tungsten mineral resources, starting in 2002, the state shall practise a planned according to the protective exploitation of specified minerals mining rules, the comprehensive research resource reserves, existing in exploration right or mining right Settings and trend at home and abroad market demand conditions, the tungsten mining total amount control Molybdenum tube, and gradually to increase resources tax and stricter mining system and a series of measures, but these measures to carry out the effect is not ideal, tungsten concentrate yield levels every year. Excessive amounts of the main reason, it is a standard part mainly from local collective and private small mines, the mine regardless of the index limits, blind expansion; Second is the name of the other minerals mining tungsten; Three is in big mines around still exist some phenomenon of illegal mining.
Resource comprehensive utilization level needs to be improved. Tungsten after nearly a century of mining in our country, at present, the most black tungsten resources in China has almost dried up. Mining enterprises to reduce costs, there is a rich abandon poor phenomenon, individual companies or even back to the manual, half manual work, resource recovery rate is low. Enterprises, especially small tungsten mountain is basically all the individual owners lease contract operation, low technical quality, the pursuit of short-term interests, mining rich abandon poor, difficult to pick by master abandon time, easy to abandon the predatory exploitation of phenomenon is common, waste resource loss is great, beneficiation process simple, low efficiency, adopted by the recovery of tungsten concentrate, only accompanying the rest of the most valuable metal is not recycled, not only the recovery rate of tungsten is extremely low, many associated metal elements is wasted. Individual companies even not built or built after not using tailings, discarding the backfilling of tungsten and the grade of the valuable metals are high, with associated also did not get reasonable utilization of resources, low comprehensive utilization of resources. Abandonment of backfilling materials not only caused the waste of resources, also caused many environmental problems.
Mining science and technology input, less acquisition technology and equipment level is not high. Lack of tungsten dressing technology research input, loss of many professional and technical personnel, technical level is unbalanced development, mining of innovation ability is not strong. Tungsten beneficiation research is less, the basis of new separation equipment research and development also largely stalled, part of the refractory ore beneficiation technology is still no new breakthroughs, such as the weathering scheelite recovery has struggled to get good results. Hard to choose black and white tungsten mixed ore dressing technology is not perfect, still has larger ascension space in ore dressing indexes. Exchange of experience and tungsten mines abroad processing technology also very few. For tungsten beneficiation dressing plant, foreign technology understand less, not to mention the introduction of advanced technology absorption.

The nature of molybdenum
     Of molybdenum and tungsten is very similar in nature, its boiling point, and outstanding electrical conductivity, thermal expansion coefficient, more easily processed than tungsten.
     Molybdenum metal thermal conductivity [135 W / (m · ON)] and specific heat [0.276 kJ / (kg · f open)] was the best match, making it a thermal shock and thermal fatigue of natural selection. Its melting point is 2620 ℃, inferior tungsten, tantalum, but the density is much lower than, so its specific strength (strength / density) than tungsten, tantalum and other metals, in the weight requirements extremely critical applications, more active. Molybdenum at 1200 ℃ still high strength.
     The main disadvantage of Molybdenum tube high temperature oxidation resistance is poor (above 600 ℃ rapid oxidation) and poor ductility at room temperature. As weaknesses, problems for multi-use high-temperature oxidation coating (such as paint MoSi2, nickel, chrome, etc.) way to control; pair of plastic which is usually too poor to say the lack of low-temperature embrittlement, and processing people through strengthening alloy carbides to achieve enhanced and other measures to solve.
     tungsten carbide plate (W), rhenium (Re), tantalum (Ta), titanium (Ti) and zirconium (Zr), etc. are common solid solution strengthening element. Tungsten is the primary solid solution strengthening elements molybdenum, rhenium can be extended to brittle transition temperature dropped -200 ℃. Formed by them industrial molybdenum alloy Table 1-1. Which constitute the lanthanum molybdenum lanthanum alloy shows very prominent and high temperature creep deformation capacity, which at high temperatures, this feature is particularly evident.

Molybdenum wire scrap recycling

Molybdenum is a refractory metals. Gray surface gloss, high melting point. Strong binding force between atoms at room temperature, high temperature, high strength, expansion of small, high conductivity, good heat dissipation; therefore molybdenum wire scrap recycling is a major refining "Mo" materials, waste molybdenum wire through: Roasting and acid, alkali treatment refining "Mo" metallic. Recycling of waste Molybdenum tube can be used to produce industrial molybdenum oxide, molybdenum, ammonium molybdate, and other such. Molybdenum wire scrap recycling, especially from the spent catalyst obtained molybdenum in molybdenum production occupies an important position, known as the second largest source of supply of molybdenum (the largest source of byproduct molybdenum, the second largest source of primary molybdenum production). Since a wide variety of molybdenum-containing waste, recycled in different ways, molybdenum regeneration methods are commonly used: the sublimation method, zinc and alkaline leaching melting method, etc., generally 96-98% recovery of molybdenum. Molybdenum wire scrap recycling plant waste molybdenum wire according to the composition and refining plant-specific conditions select or develop appropriate methods to obtain a higher economic efficiency.

Molybdenum is a transition element Molybdenum crucible powder, easily changes its oxidation state, the oxidation-reduction reaction in the body plays a role in electron transfer. The oxidized form, the molybdenum is likely to be in the +6 state. Although the electron transfer during which it is also likely to be restored first +5 valence state, but after the restoration of the enzyme has been found in other molybdenum oxidation state. Molybdenum is a xanthine oxidase / dehydrogenase, aldehyde oxidase and sulfite oxidase components, thereby acknowledge their animals for the human body and essential trace elements.

Mo (Molybdenum) Introduction

  This soft black mineral Molybdenum tube (molybdenum disulfide, MoS2), looks very much like graphite, and has been considered to be a lead ore until 1778, Carl Scheele analyze it and prove that it is not the lead can than graphite, but he did not recognize it.
Others speculate that it contains a new element, but it's hard to metallic. It can be converted to the oxide, when added to water, the formation of acidic substances, we now know that it is molybdic acid, H2MoO4, but the metal itself or elusive.

Scheele put this question to the Peter Jacob Hjelm. He put together into a molybdic acid and carbon to form a paste linseed oil, heating it red hot and producing molybdenum metal. This new element has been declared in the autumn of 1781,
