Industrial Furnaces

We offer range of wire take up unit for galvanizing plant, patenting furnaces. The take up unit consists of :

• Fabricated base frame
• Gear-train with extended output shaft to mount clutch, coiler, lock nut
• Each coiler is provided with two sets of killing pulleys
• Gear-train is coupled with hexible couplings.
• The take up unit is available in 600, 550, 450, 400, 300 & 200 dia mm coiler size.
• On load variable drive is provided in consultation with customer

• Electrically heated with automatic temperature control.
• Fuel fired using gas/oil
• The furnaces are suitable for annealing of ferrous and non ferrous materials. The furnaces use retort assembly either sand sealed or vaccum sealed under inert atmosphere. For MS wires retort assembly is sand sealed (binding wires) or vacuume sealed for scale free annealing of wires to be used for electro-galvanising. For alloysteel wire coils are processed under vacuum and inert atmosphere to prevent decarburization.  For copper wires retort assembly is vacuum sealed. Retort assembly with circular fan is used for High-perm decarburization of electrical stampings.
• Normally the furnace uses AISI-304 steel pot for maximum chamber temperature upto 800۫  c and thereafter AISI-310 steel upto 1000 c.
• The pot is fabricated using dished bottom for improved mechanical strength. The furnace is constructed using various grades of ceramic fibre blankets and refractories.
• Provision for Water Cooling of rubber seal gives good life of seal.

Bell type Annealing Furnaces :

We make bell furnaces for Higher charge output, carbon steel & alloy steels under inert atmosphere to minimize decarburization. The furnaces could be made available from 1 - 7 MT per charge.

Brass wire annealing furnace consist of number of seamless pipe of required grade of steel. The pipes are arranged horizontally at a defined pitch. Each wire uses 1 pipe. The pipe longitudinally the pipe runs in three zones pre-heating, heating & soaking. Pipes are heated through top & bottom heaters  designed at 800 to 1000 degree C. The cracked ammonia gas is supplied in each pipe to get scale free annealing of running wires. Wires are cooled in air-cooling zone before spooling.

We make continous type multi wire annealing furnaces (copper wire annealing furnaces) wherein wires travel through AISI 304 seamless pipes dipping in water tank. Inclined furnace pipes have steam cloud in the pipe to prevent wire oxidation. Running wires are wiped off water and are dryed in oven before spooling.

Similarly continous furnaces are made for brass wires  wherein cracked amonia gas is introduce at the wire exit to get scale free annealing of brass wires.
