In the process of blue blue temperature is different for different materials, the temperature of the high speed steel is generally other carbon steel and low alloy steel, oil removal and blue as the main components of the main liquid, are aqueous solution of caustic soda and the only their content is different. In particular, it should be pointed out that the products of welding parts should be heated and insulated at a higher temperature first, and then heated and insulated at a lower temperature. All products in blue temperature should not be too high and too low. Too high will affect the quality of blue, too low will increase the heating time. The deficiency, looks forward to pointing out!
