The trolley furnace is a periodic operation furnace, and the furnace is not divided into regions. The structure of the trolley furnace: the bottom of the furnace is a movable trolley. Vacuum Hardening Stainless Steel Before heating, the trolley is loaded outside the furnace, and the heating parts are placed on the special pad iron, and then the trolley is pulled into the furnace by the traction mechanism for heating. After heating, the trolley is pulled out of the furnace by the traction mechanism to unload, and then Or use a crane to lift the heated workpiece to the forging equipment for processing.Metallographic Inspection Knowledge of Bolt Quenching And Tempering Regularly check the condition of the heating elements. The heating element must not be bent or collided after a short period of use. If it has not been severely corroded and broken, the same material as the electric furnace wire (or the electric furnace wire itself) can be used as the electrode, and acetylene gas is used for heating and welding. The electrode is made of 50% Baiyun powder. If the heating element is severely corroded and cannot be used, should be replaced.Ion Nitriding vs Gas Nitriding Regularly check the use of instruments and thermocouples to prevent incorrect temperature measurement due to errors in instruments and thermocouples and affect product quality.Sintering of B4C by Pressureless Liquid Phase Sintering
