Heat Treatment Furnace Manufacturer in India, Heat Treatment Furnace Prices and Types of Furnaces

heat treatment furnace manufacturer

Heat treating (or heat treatment) broadly refers to a group of thermal processes in industrial and metalworking applications used to intentionally alter the physical, and sometimes chemical, properties of a material (usually a metal).  These physical and chemical property alterations typically come in the form of hardening or softening of a material via heating and chilling at extreme temperatures.  Heat treating occurs at temperatures above 1,000° F, and often in excess of 1,700° F.  MAAN ENERGY is the leading heat treatment furnace manufacturer in India.

ENERGY PERFORMANCE ASSESSMENT OF FURNACES.

Desired workpiece physical and chemical properties are achieved through heat treatment techniques such as annealing, case hardening, precipitation, strengthening, tempering, normalizing, and quenching.  MAAN ENERGY designs and manufactures thermal processing furnaces that incorporate all these heat treatment techniques that are known for their heating uniformity, low maintenance needs, and cost-effectiveness.

Aluminum heat treatment is a process by which the strength and hardness of a specific subset of aluminum alloys, namely the wrought and cast alloys that are precipitation hardenable, are increased. Precipitation hardenable aluminum alloys include the 2XXX, 6XXX, 7XXX and 8XXX series. In addition, annealing may be required for parts that have experienced strain hardening during their forming process. We are the leading heat treatment furnace manufacturer in India including forging furnaces and stress relief furnaces.

The typical aluminum heat treatments are annealing, homogenizing, solution heat treatment, natural aging, and artificial aging (also known as precipitation hardening). Depending on the exact process being used, furnace temperatures can range from 240 to 1000°F. It is important to keep in mind that the heat treating of aluminum is quite different from steel.

Almost all of the aluminum heat treatments mentioned above require extremely precise control over temperature in order to achieve the desired effects. This involves the use of high-quality furnaces and ovens that can achieve a uniform temperature distribution, extremely accurate control instruments, and skilled technicians that know how to use the equipment properly.

Not only must the correct temperatures be reached, but the temperature-time cycles for the heat treatment process must possess uniformity and continuity. In addition, the furnace must be designed so that the part being treated achieves a uniform temperature throughout.

When making aluminum parts for aerospace and automotive applications, the global pyrometry specification ASM2750E (Aerospace Material Specifications) is used. 

Aluminum heat treatments can be complicated processes with very little room for error or delay. That’s why we designed our ovens with ASM2705E in mind. Our ovens include highly accurate controllers and the interior of all of our furnaces is designed to achieve a uniform temperature distribution. We even offer state-of-the-art quench tanks to support precision in that final but crucial step of solution heat treatment.

The ideal solution for customers performing aluminum heat treatments is one of the furnaces that is designed for use with aluminum along with a pyrometry package to support the calibration, testing, and documentation that is required. MAAN ENERGY Special Furnace offers both. Contact us today to find out how we can help you.

Heat treatment of metals, Types, Process of Heat Treatment and Applications

Vacuum Heat Treatment Furnace Manufacturer in India for heat treatment of metals

For more than 15 years we have designed and built continuous furnaces and production lines for heat treatment of tubes for ferrous, stainless steel and alloy materials.

Heat Treatment is the controlled heating and cooling of metals to alter their physical and mechanical properties without changing the product shape. Heat treatment is sometimes done inadvertently due to manufacturing processes that either heat or cool the metal such as welding or forming.

The technology is often associated with increasing the strength of material, but it can also be used to alter certain manufacturing objectives such as improve machining, improve formability, restore ductility after a cold working operation. Thus it is a very enabling manufacturing process that can not only help other manufacturing process, but can also improve product performance by increasing strength or other desirable characteristics.

Steels are particularly suitable for heat treatment, since they respond well to heat treatment and the commercial use of steels exceeds that of any other material. Steels are heat treated for one of the following reasons:

  • Softening
  • Hardening
  • Material Modification

Process Applications

  • Full annealing,
  • Bright annealing,
  • Solution annealing,
  • Stress relieving,
  • Hardening & tempering,
  • Spherodize anneal,
  • Tube heating,
  • Hot piercing & extrusion,
  • Preheating of tubes for SRMs.

ADVANTAGES OF SOLUTION HEAT TREATMENT

  • The main purpose of aluminum heat treatments is to increase the strength and hardness of a specific subset of aluminum alloys, namely the wrought and cast alloys that are precipitation hardenable.
  • For a certain period after quenching, aluminum alloys are softer and easier to form, following which age hardening occurs.
  • The solution heat treatment process improves mechanical properties.
