Tube furnaces are mainly used in metallurgy, glass, heat treatment, lithium battery positive and negative materials, new energy, LED luminescent materials, abrasive tools and other industries to measure materials under certain atmosphere conditions. Vacuum annealing process of steel ring The tube furnace is protected by hydrogen filling after vacuuming, and uses the principle of medium frequency induction heating to generate high temperature in the tungsten crucible in the coil tube, and conducts it through thermal radiation. Powder forming and sintering of tungsten, molybdenum and their alloys.Research on Properties of H13 After Vacuum Nitriding 1. After the tube furnace is used for the first time or not used for a long time, it should be baked at a temperature of about 120°C for 1 hour, and then used at a temperature of about 300°C for 2 hours to avoid cracking. The furnace temperature should not exceed the rated temperature as far as possible, so as not to damage the heating element and furnace lining.SWD700 PLC CONTROL 3D BEAMS DRILLING MACHINE It is forbidden to directly inject various liquids and dissolved metals into the furnace, and keep the furnace clean. 2. If a quartz tube is used in a tube furnace, when the temperature is higher than 1000°C, the high temperature part of the quartz tube will become opaque. This is called devitrification, which is an inherent defect of quartz glass tubes and is normal.HDZL SERIES SINGLE SPINDLE HIGH SPEED CNC BEAMS DRILLING MACHINE
