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.

We Kalyani Enterprises also offer Solutionizing and Aging furnaces for aluminum casting industries. We offer batch and continuous solutionizing furnace. Features of furnaces 1. Minimum vibration 2.

The Rotary Hearth Furnaces are used for various treatment processes such as case hardening and carburizing (low case depth), neutral hardening, reheating, tempering carbonitriding (low case depth), annealing etc. The types of products which can be processed are quite varied being Automotive Components, Bearing Components, Forgings, Off Road/Agricultural components, Powdered Metal components and Aerospace components. Generally, after forging and trimming all jobs are kept aside to cool down for further process. The main purpose of this Rotary Hearth Furnace is to utilize the waste heat after forging.Thus being a continuous operation the job will leave the press at about 800 to 850 degree temperature and it will be put in the furnace for next process, like normalizing annealing or homogenizing where the required temperature are between 850 degree to 1020 degree c based on the process. thereby by drastically minimizing the required power for reheating. As the job is loaded at temperature of 800 - 850 degree, energy input to raise the required processes temperature is reduced by 60 %to 65%, with this furnace. we can save more than 60% energy in heat treatment. Available in various capacities starting from 500 kgs to 5000 Kgs Fuel: Gas/LDO/HSD/ Electricity
