45KW PID Control Electric Heat Treat Annealing Furnace For Steel Wire Coils

Application of Electric Heat Treat Furnace  heat treat furnace 

The pit type annealing heat treat furnace is used for annealing and spheroidizing heat treatment of metal wires,

steel coils and alloy wires.The heat treatment furnace is suitable for heat treatment 950℃ such as high temperature

annealing other heat treatment process.

Technical Parameters of Electric Heat Treatment Furnace heat treat furnace

Equipment description and technical proposal

The RJ2-45-9 pit type annealing furnace is comprised of furnace shell, furnace lining, heating element,

furnace cover, electric control system and temperature automatic control system.

1 Furnace shell

The furnace shell is made from 10# ~12# sectional steel and the furnace bottom plate

thickness is 6mm . The shell has enough strength and rigidity so as to bear the weight of the workpieces.

2 Lining

The furnace lining is all fiber structure which are fixed to the furnace body by stainless steel

fixtures. The total lining thickness is 320mmm, including 300m pre-compressed fiber block and 20mm backer cotton.

3 Heating elements

The furnace employs quality 0Cr25AL5 high temperature alloy belts as heating elements.

The porcelain bolts and gaskets are of corundum material sintered under high temperature.

The furnace has 1 temperature zone.

4 Furnace cover

The furnace cover is made of 12# U-steel and 6mm steel plate. The heat preservation material adopts aluminum

silicate fiber compression block and it was fixed by stainless steel pieces. The opening method of the

furnace cover is by crane. The furnace cover is sealed by sand.

5 Muffle tank

The muffle tank is made from 6mm 321 stainless steel plate. It is placed in the furnace hearth.

6.  temperature control system

The furnace inside temperature is controlled by the intelligent temperature controller through PID regulation. The heating control is through SCR control. Each heating zone is set with one over-temperature alarm. The audible and visual over-temperature alarm would be activated if one zone temperature is over the limit.

Electrical control cabinet: the cabinet is made according to industrial standard, and all wire numbers are clearly printed.
