HEAT TREATMENT FURNACES FOR LONG
GROWMECH has successfully supplied heat treatment lines for long products which provide a wide range of applications in continuous and batch operation to several clients in many countries.
Our heat treatment lines are advanced process technologies for a full range of heat treatment from preheating before forging, to normalising, annealing, stress relieving, tempering and hardening.
Annealing
Quenching
Tempering
Selective Heat Treating
GrowMech heat treatment furnaces use different maximum temperatures and cooling rates depending on the application and the required reaction.
The heat treatment furnaces also cool materials at a rapid rate to produce the desired results. They produce a harder metal in ferrous alloys and a softer metal in non-ferrous alloys.
Our heat treatment furnaces help to reduce the brittleness and remove any stresses caused by quenching. To do this, the steel is heated to a specific temperature and then cooled.
The heat treatment furnaces are used to alter the properties of only a portion of a material. This produces improved strength, wear resistance or impact resistance where it is required in certain sections of a material.

Some of the Heat Treatment Lines in GrowMech Range (These include electric heating)
Hearth Furnace
Our hearth furnace is used for bars, plates, coils and tube. It operates at 600oC to 1,350oC. Its functions also include:
- Preheating before forging
- Stress relief in metal products, pressure vessels, rolls
- Various annealing processes
- Quench and tempering
- Normalizing
Roller Hearth Furnace
This operates from 600 ̊C to 1,350 ̊C temperatures and is used for bars, tubes, wire rod coils and heavy plates. Its applications include:
- Annealing
- Quench and tempering (austempering)
- Normalizing
- Stress relief
Specialty Furnaces
These furnaces operate with a variety of fuels to achieve process temperatures up to 1,200 ̊C. Their applications include strip coils, wired rod coils, cast iron tubes or graphite electrodes. We have the following range:
- Rotary hearth furnaces
- Bell furnaces
- Graphite electrode bogie hearth furnaces
- Chain pushers
- Chamber, in/out furnaces
- Vertical or horizontal ladle preheaters and dryers
- Controlled cooling hoods or cooling beds for tubs
Rotary Hearth Furnace
It is used for reheating all semi-finished products, such as round or square billets for seamless pipe mills and forging plants, high grade steel ingots for railway wheels, and heat treatment (annealing, quenching) of wire rod coils. It ensures optimal performance and easy maintenance.
Forging Furnace
Its applications include ingots, square or round billets. The range includes:
- Batch type bell or chamber, in/out furnaces
- Pit furnaces
- Bogie hearth furnaces
