According to the user's application environment and operating temperature, Lighthouse Group can provide to the user the most suitable pure Molybdenum crucible or molybdenum alloy.
Chemical characterization:
Atmosphere without oxygen, molybdenum variety of acids, liquid metal and the molten glass has a very good resistance to corrosion. At 1100 ° C or less, Mo in hydrogen, nitrogen, ammonia and relatively stable molybdenum and steel welding a) molybdenum and steel welding - brazing molybdenum and steel (carbon steel, stainless steel) using welding, electron beam welding and gas welding and other welding methods, welding can be achieved - brazed joints. This welding process is the essence of the steel side of the molten metal more, and molybdenum increase the side just heating without melting or melting little liquid metal is steel formed by infiltration brazed seam. This avoids the formation of iron and molybdenum compounds Fe3 Mo2 and FeMo, the joint area embrittlement problem is solved. Molybdenum steel electron beam butt welding directly, the weld metal composition mainly 20Mo-80Fe in the Mo base material is displayed on the side of the boundary eutectic α + ε, and the formation of large intermetallic Fe3 Mo2 and FeMo. Since the presence of intermetallic compounds, the weld metal brittle and easily cracks increases, reducing the performance of the joint, its poor weldability. Therefore, molybdenum and steel fusion welding, the joint strength is not high, you should avoid direct welding, it is generally used welding - brazing.

Before and after the ceremony, there are a few users on the project environmental issues discussions. July 1st evening 19:00 or so, some people in Shifang Municipal HTC Square near the entrance and gathering, requiring cessation of the project. The propaganda and explanation and persuasion, that night 24 o'clock, gathered all the people dispersed.

July 2 morning, after another people to Shifang Municipal Government gathered in front against the molybdenum-copper project, a few members of the public agitation, forced to break through cordon to enter the municipal authorities, smashing windows and lobby 8, 3 billboards, four promotional display panels. By the local party committee and government leaders and field staff patiently grooming, most onlookers have left, but there are still a few people to continue to gather congestion. Around 13:30 pm, the scene gradually increasing crowds in individuals instigate, incite, the minority community impact municipal authorities again forced the door to the police vigilance task being performed and office workers throwing pots, water bottles, miscellaneous material, resulting in more than police injured site, nearly official vehicles damaged to varying degrees, the door was pushed organs, damage, seriously affecting the social stability and organs normal office order. Police on duty and the staff has always maintained restraint, insist on playing does not fight back, reviled not. In order to prevent deterioration of the situation, causing more serious consequences, at 14 am, police were forced to perform vigilance tasks take measures against radical groups to be dispelled. In the dispersal process, several thousand people suffered minor injuries, were promptly transferred to hospital for treatment.

Molybdenum materials in the petrochemical industry applications

The density of 10.2 g of molybdenum / cc. Melting point 2610 ℃. Boiling point 5560 ℃. In the Cape molybdenum powder made by isostatic beat green and sintered at about 2100 ℃ at 870 ~ 1260 ℃ within the range of thermal processing. Can be obtained through the plastic processing molybdenum alloy sheet, strip, foil, tubes, rods, wire and profiles, add different ingredients in the Cape after Ferrous Metals Ltd. also improve its strength and improve the low temperature ductility.
Molybdenum crucible is also very stable chemical properties, can not be hydrochloric acid, hydrofluoric acid, and the alkali etching, but in the nitric acid, aqua regia, or hot concentrated sulfuric acid may be corroded. Molybdenum is also an important additional element. Mo is effective at high temperatures accelerate the solid reinforced to prevent chloride pitting, but also improve the corrosion resistance of the stock solution.
A large demand for oil has forced people to accelerate on land and sea in deep oil extraction, and deep reservoirs often subjected to corrosive two hydrogen sulfide, carbon dioxide and high chloride brine contaminated and Molybdenum target from 0.15% to 0.25% AISI 4100 series of Cr-Mo steel is widely used. Improved molybdenum 0.4 to 0.6% of 4140 series of sulfide stress corrosion cracking (SCC) most resistant low-alloy steel, for the use of sulfur-containing wells.
 With the deepening of the drilling depth and the deteriorating conditions of use, higher stainless steel containing molybdenum and nickel-based alloys, such as alloy C -22 (13% Mo) and alloy C -276 (16% Mo) applications will continue to increase. Since chromium steel surface in a thin natural protective passivation film, so stainless steel has corrosion resistance. In fact, molybdenum make this more robust passivation film, and chloride in the passivation film is destroyed it quickly regenerated. Increased molybdenum content to increase stainless steel pitting corrosion resistance and crack. 316 (2% ~ 3% Mo) is the most widely used stainless steel containing molybdenum. It is designated for food handling and processing and pharmaceuticals production and use of tanks, pipes and heat exchanger materials. Increased molybdenum content can enhance the air resistant to chlorides, so that 316 can also be used as the surrounding sea and coastal extensive use of the material of choice.
   When the Mo in the air reaches a temperature above about 600 ℃ easy to form volatile oxides, the application of high temperature molybdenum preferably in an inert gas or vacuum environment

Domestic tungsten tungsten iron ore market was steady spot market supply

Tungsten wire  domestic market is relatively steady, APT high steady, the actual turnover remained weak, tungsten, iron spot market supply, manufacturers continue to raise prices, tungsten products and scrap tungsten market was also found slightly buoyant trend.
Tungsten market: domestic tungsten ore market is relatively steady, some traders purchase price down to 14 yuan / ton, APT high steady, the actual turnover remained weak, tungsten iron spot market supply, manufacturers continue to raise prices, tungsten products and scrap tungsten market was also found slightly buoyant trend. We expect short-term strength of tungsten products mainly downstream market, the market environment has been heating up.
Molybdenum crucible market: long-term sustainability deserted market, causing businesses to invest mentality change dramatically. Molybdenum products market trend poor performance, primarily due inquiry and orders shrank impact. No significant improvement in the downstream steel city signs, and the current in the off-season, it is difficult to play a strong support for the upstream markets. We expect short-term molybdenum prices will remain weak consolidation phase.Downstream, as the international price indices in the domestic APT (APT) last weekend price 213,000 yuan / ton, ring up more than 04,000 yuan / ton; sodium tungstate price 144,000 yuan / ton, ring up more than 07,000 yuan / ton ; tungsten powder price of 327.5 yuan / kg, and ring up more than 5 yuan / kg.
Industry analysts said the biggest change in June tungsten City has two: one, the downstream product of tungsten sudden rapid follow up. Previously, that after the Spring Festival this year, tungsten small step up fast, but because of a bad deal tungsten downstream product price increases difficult, resulting in price upside down; two, CMN early June will offer a one-time increase of 20,000 yuan / ton, to wolframite 155,000 yuan / ton, or 14.8%, much higher than Ganzhou Tungsten Industry Association in June 2000 yuan per ton, up offer. "CMN one up so much to influence the market bullish atmosphere, led lower prices."

Why Gui has to be coated with an insulating material

Why plating chemical degreasing to weak acid etching from the middle to go through the rinse?
A: Because the general chemical degreasing solution is alkaline, if the degreasing solution is directly brought into the acid etching solution, will an acid, a base neutralization reaction, reducing the acid concentration and effect. Neutralization reaction product adhering to the workpiece, will affect the quality of the coating. Tungsten eletrode, the workpiece in the chemical degreasing, be sure to rinse with water after, to enter the acid etching solution.
7 galvanizing glitches, coarse, usually those causes, how to solve?
A: The coating glitches, coarse, mainly by plating suspended impurities caused by pollution. Their sources are: air, dust, anode sludge, metal impurities hydrolyzate. In addition, the bath composition and abnormal operating conditions and so undesirable. The solution is: alignment bath composition and operating conditions. If it is caused by suspended impurities, they should be filtered bath.
8 plating solution formulated the basic procedures How to:
A: The basic procedures for the preparation of the plating solution is as follows:
(1) will be required for a good amount of juice into the open chute before plating drugs (small tank) inside, then add the right amount of water dissolved careful not to drugs directly into the plating tank.
(2) solution of impurities can be cleared with a variety of chemical methods, and activated carbon treatment.
(3) stand a good solution has been processed, filtered into a clean plating bath, add water to a standard amount.
(4) regulate the plating process specification (pH, temperature, additives, etc.).
(5) Finally, the electrolytic deposition of a low current density in order to remove other metal ion impurities, until the solution is suitable for operation so far.
9 Why Gui has to be coated with an insulating material?
A: In addition to the general hook hanging with Molybdenum crucible and product contact with conductive parts, the rest should be coated with an insulating material to reduce the current loss and metal loss, ensure the effective area of ​​plating, improve the effective current, and to hang with durable.
