A general process of steel production is as follows: iron making → steel making → continuous casting (or die casting) → hot rolling (out of hot rolling products) → cold rolling (out of cold rolling products). First, let’s take a look at what kind of cold rolled and hot rolled […]

Advantage of Energy Saving 1. The heating speed of medium frequency furnace is fast: since the working principle of medium frequency furnace and medium frequency electric furnace is electromagnetic induction, its heat is produced in the workpiece. Ordinary workers can carry out continuous forging work in 10 minutes after

Blast furnace for rolling mill machine is of great importance in steel rolling process. Blast furnace smelting is the continuous production process of reducing iron ore into pig iron. Solid raw materials such as iron ore, coke and flux are fed into the blast furnace in batches by the top
Roughing rolling mill is a machine for rolling steel. Rough rolling is in the middle of heating and intermediate rolling mill, and its function is to process the heated slab by a roughing rolling mill into an intermediate blank that satisfies the finishing requirements (specification, temperature, surface quality, plate type).
