Pit Type Furnace

Mass Engineers is one of the Pit Type Furnace Manufacturers in Maharashtra. We have a full range of Pit type Heat Treatment up to a capacity of 100 MT for hardening, annealing, normalizing, carburizing, nitriding, tempering, aging, and stress relieving to offer to industries like Fasteners, Bearings, Forge Parts, Gears, Rolls, Strip, Wire, Piston rings, etc. in steel industries besides cylinder heads and pistons for Aluminium industries. We also Offering Gas carburizing furnace is basically a pot-pit type furnace used for hardening case carburizing carbonitriding of various components made of steel such as construction machinery parts, precision turned components, gears, auto parts, etc. These Gas carburizing furnaces are of circular construction with an insulated cover, which is hydraulically lifted/swiveled for charging or discharging the material into and from the furnace. The charge material can be loaded into the Pit furnace with the help of an EOT crane or a suitable loading machine. The Pit furnaces can also be offered with quenching facilities as per customers’ requirements.

As a leading Pit Type Furnace Manufacturer in Miraj. Pit furnaces are offered with or without sealed retorts for inert/reducing atmosphere or normal oxidizing atmosphere applications. The furnaces with inert/reducing atmosphere applications will have a facility for introducing atmosphere-like hydro-carbon-rich gas, ammonia, and nitrogen into a sealed retort made of stainless steel of AISI-310/304 depending on the application temperature. The lid is fitted with gas tight water-cooled neoprene/silicon rubber seal for proper sealing. These Gas carburizing 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 a number of heating zones and can be controlled through a contactor or thyristor-based control philosophy through PID controllers. Fuel-fired Pit furnaces are offered with high-efficiency burners for Oil/Gas applications supported by a full complement of combustion control systems with safety devices.

As one of the best Pit Type Furnace Manufactures and Exporters from India. Hot air circulation inside the furnace is made by an efficient centrifugal or axial-type recirculation fan, which can be with a two-speed motor or with a VFD drive. Pit furnaces are lined with ceramic fibre blocks/modules at the sidewall and lid cover. The bottom hearth will be lined with refractory bricks backed by insulation bricks, specially designed to withstand a load to minimize skin temperature. MASS FURNACES has full capability to offer complete control and instrumentation system through PLC-based or Hardware based logic controls.
