Pit Type Furnace
Our organization holds an prime position in the market as the manufacturer, supplier and exporter of Pit Type Furnace. These products are used for annealing different types of steel parts and fixtures. Known for their high durability and strength, these products require very less maintenance. These products are absolutely free of corrosion and abrasion. Pit Type Furnace is delivered to the clients in a stipulated time frame owing to our expert delivery team.
Indomen has a full range of pit type Heat Treatment up to a capacity of 30 MT for hardening, annealing, normalizing, carburizing, nitriding, tempering, aging and stress relieving to offer to industries like Fastener, Bearing, Forge Parts, Gears, Rolls, Strip, Wire, Piston rings etc in steel industries besides cylinder heads and pistons for Aluminum industries.
Normally these furnaces are of circular construction with insulated cover which is hydraulically lifted/swiveled for Loading or Unloading the material into and from the furnace. The charge material can be loaded into the Pit furnace with the help of EOT crane or suitable lifting/lowering arrangement.5pecially for Carburising application Pit furnaces can also be offered matched quenching facilities, washing machine and tempering furnace to suit customers' requirement. Pit furnaces can be offered with or without sealed retorts for inert/reducing atmosphere or normal air atmosphere applications.
The furnaces with inert/reducing atmosphere applications will have facility for introducing atmosphere like carbon rich gas, ammonia and nitrogen into a sealed retort made of stainless steel of AIS1Ã‚310/304 depending on the application temperature. The lid is fitted with gas tight through water-cooled neoprene/silicon rubber seal for proper sealing.
These furnaces can be either electrically heated or fuel fired The electrically heated furnaces are provided with resistive strip/wire heating elements located on the sidewall of the furnace. The heating elements of the furnace are suitably divided into number of heating Zones and can be controlled through contactor or thyrister based control philosophy through PID controliers. Fuel fired Pit furnaces are offered with Wesman's high efficiency burners for Oil/Gas application supported by a full complement of combustion controI system with safety devices.
Hot air circulation inside the furnace is made by efficient centrifugal or axial type recirculation fan which can be variable WFD drive as per required temperature application. Pit furnaces are lined with ceramic fibre stack/module at side wall and lid Cover. Bottom hearth will be lined with refractory bricks backed by insulation bricks, specially designed to withstand load to minimize the skin temperature.
Indomen has full capability to offer complete control and instrumentation system through PLC based or Hardware based logic Systems.
