Reheating Furnaces

We offer Reheating Furnaces. Our superior quality reheating furnaces are developed from top notch technology and they could be pusher, walking hearth or walking beam – either top fired or top and bottom fired. The fuel that is utilized in these furnaces could be either oil, or coal or gas. The burners are capable of fulfilling the desired objective of uniform heat distribution. We have gained enough specialization in designing and manufacturing reheating furnaces that are used in various engineering related industries. They have long service lives and are available in various designs like pusher type, double zone pusher type, triple zone pusher type and triple zone bottom fired. These have been designed and developed with the help of imported and modernized machinery are highly reliable, efficient and are offered in the following specifications:

 

  • Capacity: 5 to 50 tons / hr
  • Temperature: 1300°C

Reheating Furnace is the heart of any hot rolling mill where in the charge is heated to rolling temperature. The charge could be in the form of billets, blooms, slabs or ingots.The type of furnace could be pusher, walking hearth or walking beam – either top fired or top and bottom fired.The fuel used could be either oil or gas. The burners are located in a manner so as to achieve uniform heat distribution. The radiation heat energy is efficiently transferred through the useful heat transfer area created by the charge bed.The furnace is basically divided into three zones namely preheating, heating and soaking zones. The actual heating takes place in the heating zone. The temperature uniformity up to desired limits between the core and the surface is achieved in the soaking zone. The flue gases move in a direction opposite to that of the charge thereby ensuring considerable amount of waste heat recovery by convection in the preheating zone, which is also termed as the recuperative zone.

Our furnaces are highly fuel efficient due to proper roof profile / zonal distribution, optimum preheating / recuperative zone lengths, proper burner / flue port locations and good instrumentation including furnace chamber pressure control eliminating atmosphere air ingress, which also reduces the scale loss and decarb of the charge.

We are offering excellent quality Continuous Heat Treatment Furnace, which are heavily used for functions like carburising, nitriding, hardening, case hardening, annealing, malleability, etc. Sealed quench furnaces, continuous conveyor furnaces and pit-type furnaces, qualify as famous varieties of heat treatment furnaces.

These are developed from exquisite technology and provide strength to products through heat processing. Our products are known for their long service lives and are available in resistance heated and gas/oil fired versions.

Our products could be simply maintained and are capable of accommodating a variety of materials and treatment goals with the use of optimized settings for heating and cooling temperatures, wait times, heating and cooling speeds, and ambient conditions. Competitive rates are our hallmark VNF supplies both the furnace and attendant equipments like controllers, ambient gas generators, and cooling units.

A. Pusher Type Furnaces:

These furnaces are renowned for their quality and have the capacity of operating at temperatures up to 1000 Deg. C. The items that are needed to be heat treated are put into the furnaces on trays and the loaded trays are then put into the furnace. After the process of heating and soaking is over, the material is taken out of the furnace and adequately removed from the platform. These furnaces have proved their worth and usefulness for processes like normalizing, stress relieving and various other heating processes related to different components. The overall oil consumption increases to 60-65 liters/tonne when the steel forgings are either normalized or hardened.

B. Batch Type Heat Treatment Plant:

These heat treatment plants are operated with the support and help of charging machines complete with automatic quenching system. These plants are operated by only one person and the oil consumption increases to 40 liters/ tonne due to the process of hardening/ normalizing and they increase to 30-35 liters/ tonne due to tempering.

C. Roller Hearth Furnaces:

These furnaces are designed with the help of remarkable materials and technology and they are used for continuous operations like heating various types of furnaces. Moreover, they are highly capable of operating and working at temperatures up to 1000 Deg. C. These furnaces are known for long service lives and could be oil fired, gas fired or electrically heated.

D. Mesh Conveyor Furnaces:

These furnaces are developed from grade raw materials and are used for continuous heating of components. The material is usually and effectively fed on the mesh conveyor. The mesh conveyor furnaces are mostly electrically heated, are durable, efficient, have long service lives and are highly capable of performing up to 1000 Deg. C. temperature.
