we Kalyani enterprises manufacturing Electrical Gas Carburizing furnace. Pit type sealed retort furnaces are of a cylindrical design vertically erected with a positive sealing mechanism on top in order to contain and preserve heat and atmosphere during a process cycle. The job or charge is loaded into a retort which functions as the chamber of the furnace and the retort is heated externally electrically. Pit furnaces like these are used in general engineering and metallurgical applications for carburizing, nitriding, carbonitriding, nitrocarburizing, hardening, tempering, annealing and also in process industries like coal tar processing, separation of titanium and magnesium from ore etc. Special processes such as aluminium and titanium heat treatment can also be done. In process industries, these furnaces can also be used in high-pressure applications with temperatures from 800°C to 1200°C and pressure ranging from 400mm water column to 9 bar. These are often laid in a pit to make most of the space available and charges can be loaded and unloaded easily. These are manufactured considering working controlled atmospheres with inlets for diffusion and distribution of cracked ammonia, hydrogen, LPG, methanol, argon, nitrogen and other process fluids. Kalyani manufactures and sets up complete automated process plants also. Temperature control, fluid dissociation, gas penetration and dosing can all be taken up for automated operation.

The furnace is designed in order to melt bulky returns from die casting, ingots of Al‐alloy and general aluminum scrap. This is achieved by loading die casting returns from the tower door with the skip automatic loader or hydraulic loader and melting the aluminum in the dry chamber, on a little inclined surface made of castable refractory. The liquid aluminum can therefore flow into the main basin, placed at the back of the furnace. 1. Maximum height of smelted bath : ≈ 750mm. 2. Spillage of melted aluminum: By tilting the furnace on the axis of the spout with oil dynamic system and cylinders. 3. Heating of the furnace: By combustion plants driven by Diesel Oil / LPG / Methane, depending on customer needs, made up of automatic burners and all the safety protections. Dry Melting chamber and Holding Chamber are thermally independent and burning systems work under different control purposes 4. Thermal power installed : 10,00,000 ‐ 30,00,000 Kcal/h depending on furnace dimensions & Capacity 5. Consumption : < 600 Kcal/Kg of loaded aluminum at 720° C. 6. High Melting Rate : 0.5 – 3.0 MT / hr. depending on furnace dimensions and on type of load . 7. Low Maintenance 8. Fast Melting Available from 500 Kgs to 3000 Kgs Capacity Fuel : Gas/Oil
