Therm process Engineering Pvt. Ltd. designs and manufactures hardening furnaces for engineering components and forgings. A hardening furnace heats steel above its critical temperature, so it can then be quenched to a hard, wear-resistant structure. Therm process builds hardening and tempering furnaces, also known as universal furnaces, which handle both steps of the heat treatment cycle. Each furnace is custom designed around the customer's components, batch size and process specification. Share your material, part size and hardness requirement to receive a recommendation.
What Is a Hardening Furnace?
Hardening is a heat treatment that increases the hardness and strength of steel. The component is heated above its critical (austenitising) temperature and held until the section is uniformly transformed. It is then cooled rapidly by quenching in oil, water, polymer or air, depending on the grade. Rapid cooling produces a hard martensitic structure. A hardening furnace provides the heating and soaking stage. Its job is to bring every part of the load to the correct temperature, hold it for the right time, and release it for quenching without delay. Temperature uniformity matters: under-heated areas won't harden fully, and over-heating can cause grain growth, distortion or cracking.
Hardened steel is strong but brittle, so hardening is almost always followed by tempering. That is why many plants use hardening and tempering furnaces together, or a universal furnace able to run both cycles.
Therm process Hardening Furnaces
Therm process designs and manufactures hardening and tempering furnaces, known as universal furnaces, for hardening and tempering applications across engineering industries. The same range is used for heat treatment of forgings. Furnaces are built from durable materials to withstand daily wear and tear, and are custom designed to the customer's specifications. Therm process sizes the chamber, heating system and loading arrangement around the actual components rather than supplying a fixed catalogue model.K
Heating can be burner-fired, using Thermprocess's own gas, oil or dual-fuel burners, or electrically heated, as per the process. Microprocessor-based controls can be specified to hold hardening temperature and soak time consistently. For stainless steel coils needing solution treatment, heavy components or continuous tempering of bars, Therm process also offers dedicated solution annealing, bogie hearth and roller hearth furnaces.
