Show Annealing Furnace :

Fuel used in heat treatment furnace: natural gas.

The front and rear steel wire inlet and outlet of the furnace are equipped with electric switch furnace doors, easy to operate

The furnace uses a high efficiency and energy saving individual blower for air supply, greatly reducing operating costs.Smoke exhaust system: the smoke is discharged from the inlet wire, through the air heat exchanger, furnace pressure electric regulating valve, through the smoke pipe into the steel chimney natural emission

Hydrochloric acid pickling (smokeless pickling)

The total length of the acid tank is 17.5m, and it is equipped with a storage tank and an upper working tank. There are three sections inside the tank, and the acid tank is fully sealed with water curtains at both ends to prevent acid mist from leaking out. Pickling is equipped with electric heating and starts at the beginning of production; During normal production, acid heating can be carried in by the heat brought in by the steel wire, and the temperature of the steel wire entering the acid tank can be controlled by adjusting the cooling water volume

Galvanizing Pot

According to the heating characteristics of the round-bottom round-corner zinc pot, the form of external heating and heating is adopted. The high-speed burner of natural gas is arranged in the diagonal corner of the hot-dip galvanized furnace. The outlet speed of the combustion product of the high-speed burner can reach 120~160m/s.

Wiping Galvanizing Wire System

Asbestos block wipe system

Can be used to produce zinc coated thin steel wire; The wire enters between the two wipes and the liquid zinc is squeezed and falls back to the zinc pool

Nitrogen wipe system

The nitrogen air knife system is designed to have high thickness zinc layers between a wide line speed. Each wire leaves the zinc-aluminum liquid and is protected in a ring by its own nitrogen gas knife
