Lead concentrate quality standard
Continuous annealing furnace with furnace roll
Make various types of roller from small diameter (60mm) to large diameter (1600mm). In particular, the large diameter Furnace Roller used in continuous annealing production line with higher reliability is highly appraising. In addition, it also produces special roller for measuring temperature and equalizing temperature.
High speed wire rod mill at home, at the wire rolling mill, rod line and use of roller slit rolling mill ring, due to the work under the roll ring in relatively poor thermal conditions, therefore must be able to withstand the wear and corrosion of cooling water and the big rolling torque and so on, at present a lot of manufacturers adopt tungsten carbide tungsten carbide roll rings, but because the cost of tungsten carbide roll ring manufacturing high, caused the enterprise production costs rise, and in view of the actual situation, our factory successfully developed special wear-resistant alloy MSW66552 series, nearly half of the manufacturing cost is tungsten carbide, the effect of using basic tungsten carbide. The e product has been confirmed by the user, MSW66552 alloy product hardness 88HS, roll surface hardness difference less than 2HS, 6000C red hardness more than 82HS, roll body radial 30mm hardness difference less than 3HS, impact toughness more than 15J/CM2, fracture toughness more than 60Mpa. M1 /2.
