1. When the electric furnace is used for the first time or is used again after long-term inactivity, it must be dried in an oven. Oven temperature and time: Room temperature - 300°C for 4 hours Open the furnace door to evaporate most of the moisture in the furnace.AUTOMATIC HORIZONTAL ROTARY ANGEL METAL BAND SAW MACHINE CH-600SA 300°C--800°C rapid temperature rise, close the furnace door. 800℃--1000℃ for 3 hours Open the furnace door regularly until there is no moisture in the furnace door.HORIZONTAL MITRE BAND SAW MACHINE CLS-650 2. When the electric furnace is used, the input power must not exceed the rated power, and the furnace temperature must not exceed the rated temperature, so as not to damage the heating element and inner furnace lining. It is also forbidden to directly pour liquid and molten metal into the furnace. Regularly clean the iron filings and oxides in the furnace to keep the furnace clean. 3. Silicon-molybdenum rods are suitable for use in air and neutral atmospheres (such as inert gases). Reducing atmospheres such as hydrogen will destroy the protective layer, and chlorine and sulfur vapors will severely corrode silicon-molybdenum rod components.Aluminum alloy finned radiator vacuum brazing 4. Silicon-molybdenum rods should not be used for a long time in the temperature range of 400°C to 700°C, because the silicon-molybdenum rods will be oxidized and destroyed in this temperature range.Sintering principle and analysis of special ceramics 5. Regularly check whether the electric furnace and the connection parts of the conductive system of the temperature controller are in good contact. (Special attention should be paid to the connection point of silicon molybdenum rod heating element.)
