Forging Steel

Galvanizing process

A processing method that uses forging machinery to apply pressure to metal billets to cause them to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes and sizes. One of the two major components of forging (forging and stamping). The forging process is centered on the plastic deformation of forgings and is completed by a series of forging processing processes.

(1) Cutting: Cutting with a grinding wheel cutter, turning the end face, and chamfering R5.

(2) Heating: Heating with an electric furnace, the furnace temperature is (450±10)℃, and the heating and holding time is 136min.

(3) Die forging: The die forging equipment is a 6300kN friction press. First, the billet is flattened to H=24mm on the upsetting table of the forging die, and then the material is placed flat in the die groove for die forging, and the pressure is 2~3mm.

(4) Heating: The furnace temperature is (450+10)℃, and the heating and holding time is 30min (second fire).

(5) Die forging Press to size.

(6) Heating Furnace temperature (450+10)℃, heating and holding time is 10~15min.

(7) Hot cutting.

(8) Pickling According to the general process regulations for pickling.

(9) Heat treatment Quenching and artificial aging according to the heat treatment process regulations.

(10) Pickling According to the general process regulations for pickling.

(11) Forging repair.

(12) Forging inspection 100% check material grade, shape and surface quality; 100% check hardness.

(HB≥140); low magnification inspection.
