OEM/ODM Request Is Very Welcome!Our Mill Roll is mainly used for cold roll mills, including supporting roll, middle roll, working roll and straightening roll.
We have 5 medium frequency furnaces and 5 electric slag heavy furnaces, which can produce 1 ton-18 tons of various types of alloy steel, with an annual capacity of 10,000 tons. The main characteristics of electroslag remelting are that it can flexibly produce various types of special steel in size and batch, with pure composition, uniform and dense crystal organization.Natural gas digital display computer temperature control heating furnace can accurately control the heating temperature of raw materials.
800T fast forging machine can quickly forge products, 3150T and 5000T oil press can forge heavy-duty axle products. They can guarantee the forging ratio required by the product, and ensure a good gold product organization.
More than 20 digital display resistance furnace can anneal, quench andtemper , so as to ensure the mechanical properties of the product.
We adopt large lathes and grinders to ensure the size accuracy and roughness of the rolls
