Used for more than a year

Used for more than a year, obviously feel the tungsten carbide roll wear are very small, and relatively long service life, use had not changed in over the past two years, compared with the frequency of the replacement once half a year before roller, tungsten carbide roller long life a lot, but basically there is no wear and tear. Tungsten carbide roller price is more expensive, but in an interview Mr Ouyang calculate so a account for us: price, tungsten carbide roller is 2.5 times of ordinary corrugated roller, use one and a half years, ordinary roller in 2 ~ 3 times already. The 02 purchases roll can use 1 year, in this case, although one-time investment is larger, but take a long-term view is value. And roll changing by human, Molybdenum tube and financial resources is an estimate and change frequency decreases, the losses are reduced accordingly. Mr Ouyang believes that although the once only investment of tungsten carbide roller is larger, or there is a big market space, the key is must mature process. But the benefits of tungsten carbide roll, there is some shortcomings also. According to Mr Ouyang said, because of the roller hardness is larger, so the work of noise also corrugated roll bigger than before. As the first domestic manufacturer of tungsten carbide corrugated roll, big pine Lin from Shanghai has found that affect the quality of tungsten carbide corrugated roll production equipment large pine are used the international first-class equipment; Price is also relatively more in line with national conditions; In addition, due to the large industrial and mining condition is very loose on the domestic a cardboard-box factory understanding, such as domestic large paper sediment concentration, etc., on craft is more close to the domestic production needs. So he think it is a big pine imported from abroad and tungsten carbide roller is more suitable for the domestic market. In early 2004, imports of tungsten carbide roller, the use of nearly a year think well above expectations in advance, even feel content value. Chen said: "from a performance, because use tungsten carbide coating, guarantees the corrugated roller has enough hardness. With this prerequisite, can produce beneficial to improving their strength of paperboard stare blankly shape, rather than to consider the design of shape of yield to the friction of core paper. Currently on the market for rock shaped lip stare blankly stare blankly and Germany BHS company is from the U, V, on the simple classification of UV type, developed the more able to make the paper play its biggest stare blankly physical indicators.
