  In our production, non-standard screws are often used, and non-standard screws also need heat treatment during processing. Do you know the heat treatment process of Threaded Rods And Eye Bolts?

  Heat treatment is a metal thermal processing technology that places non-standard screw materials in a certain medium for heating, heat preservation, and cooling, and by changing the surface or internal metallographic structure of the material to control its performance.
   
  The heat treatment process of non-standard screws generally includes three processes of heating, heat preservation and cooling, sometimes only two processes of heating and cooling. These processes are connected and uninterrupted. This process can be achieved with the help of ceramic heat exchangers. The production process of ceramic heat exchangers is basically the same as that of kiln furniture. Thermal conductivity and oxidation resistance are the main application properties of the material.
   
  Its principle is to place the ceramic radiator close to the flue outlet, where the temperature is high, without the need for cold air and high temperature protection. When the furnace temperature is 1250-1450℃, the flue outlet temperature should be 1000-1300 ℃, the waste heat recovery of the ceramic heat exchanger can reach 450-750℃, and the recovered hot air is sent into the kiln to form a mixture with fuel gas for combustion, which directly reduces production costs and increases economic benefits.
   
  Put the Hexagon Flange Bolt in a place with high temperature, no need to add cold air and high temperature protection. When the furnace temperature is 1250-1450℃, the temperature of the flue outlet should be 1000-1300℃, and the waste heat of non-standard screws can reach 450- At 750°C, the recovered hot air is sent to the kiln to form a mixture with gas for combustion, and heat treatment is performed on non-standard screws.
