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.X2 MINI MILL DRILL 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.X2L MINI MILL DRILL 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.Research on Vacuum Heat Treatment Technology of Cr12 Steel The furnace temperature should not exceed the rated temperature as far as possible, so as not to damage the heating element and furnace lining. It is forbidden to directly inject various liquids aVacuum heat treatment of 3Cr2W8V steel-aluminum die-casting moldnd 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.
