Steel Brazing Furnace | Energy Efficient

This energy efficient brazing furnace is used for brazing steel as well as ferrous and copper alloy parts. This brazing furnace will lower your operational cost while saving the environment by recycling by-produced heat and energy from the exothermic gas generator to preheat steel parts before they are brazed. By embedding the exothermic gas generator within the heating section of the furnace, this steel brazing furnace recycles energy. Therefore, unlike other gas generators that need large volumes of water to cool down, this brazing furnace saves water, energy, and costs.

Bright Annealing Furnace | Roller Hearth Continuous System

 

Our Bright Annealing Furnace provides solution annealing in a controlled atmosphere to minimize oxidation while relieving the internal stress and increasing ductility of the steel components. By applying controlled heat, the steel parts are heated then cooled slowly in our continuous oven.

This bright annealing furnace has an atmosphere gas generator embedded into the machine, which recycles generated energy from the atmosphere gas and use it for preheating the next batch of parts before they are annealed. This process saves approximately 180KW/hr for an annealing process of 2000kg/hr, and lowers the CO2 output by 27%. Save your operating costs and operate your facility with energy efficient annealing furnaces.

Not only that, although oxide scaling can be prevented in a typical bright annealing furnace, it is difficult to remove the temper colour. Our bright annealing furnace took this into consideration, and implemented a specially designed spheroidizing furnace (cooling chambers) that allows heat treatment of metal coated parts.

Bright Annealing Furnace Applications

 

Bright Annealing Furnace is required to restore the ductility after cold forming, grinding, machining, bending or drawing in order to relieve the stress built up from previous steps and to avoid cracking as the parts move on to the next manufacturing step that might use higher temperature.

Bright Annealing can be applied to steel parts, as well as non ferrous parts such as copper, aluminum or brass material.

 

Common uses of Bright Annealing Furnace

 

  • Bright annealing of steel pipes and stainless steel pipes
  • Bright annealing of copper alloys
  • For multiple controlled cooling sections – Spheroidizing and Porcelain furnace

Carburizing Furnace | Case Hardening

 

Carburizing furnace carburizes low carbon steel parts and high alloy steel parts to create a a wear resistant surface while keeping the strength in the inner core of the parts and in a continuous process. Our standard carburizing furnace runs on a mesh belt skid rails with reduced frictional resistance, making it suitable for production of large quantity metal products like fasteners, (bolts and nuts, screws, washers). With the mesh belt skid rails, it is best for demanding production yield requirements, processing heat treatment up to 1500 kg/hr.

We also have heat treatment furnaces for various case hardening process such as hardeningtempering, and carburizing upon request.
