I plant the production of high-chromium cast, bimetallic, two liquid composite products, widely used in metallurgy, building materials, mining, power and chemical industries. Which uses a bi-metallic material casting continuous casting technology, to replace the existing market hammer handle, hammer secondary casting process, so that the hammer handle hammer never broken, won the Chinese invention patent, product characteristics and high wear-set toughness in one, than the traditional high manganese steel castings advantages, its life is also longer, to bring the potential benefits related industries, in the long run more cost savings, has become an inevitable trend holds many lessons for the industry. And mining conditions, depending on the user to adjust the workpiece material, the product has good wear resistance, impact resistance, safe and reliable overall performance.
