Production
Process
We can produce various types of die
steel: hot die steel, cold die steel,
plastic die steel.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 the
flexible production of various types of
special steel in size and batch size,
with low P and S content, pure
composition, uniform crystal
structure,
dense, and high fatigue
life.
Digital display computer temperature
control natural gas
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
microstructure.
More than 20 digital display resistance
furnaces can anneal, quench and
temper，so as to ensure the mechanical
properties of the
product.
We use large lathe, milling machine,
boring machine and grinder to ensure
the dimensional accuracy and roughness
of the
shaft.
