A box-type resistance furnace operating procedures, structure and working principle SX series 1200 ℃ box resistance furnace cycle mode of operation for the electric silicon molybdenum rod heating furnace 1600 ° c, KSW type temperature control and nickel and nickel silicon thermocouple branded supporting the use of an electric furnace, thereby performing electric furnace temperature measurement, indication and automatic control. Second, do not exceed the maximum temperature resistance furnace 1. when safety practices. 2. When loading the sample taken must cut off the power, tempering furnace pit to prevent electric shock. 3. Replace the sample taken when the door opening time should be as short salt bath furnace to extend furnace life. 4. Prohibition of the box-type furnace perfusion liquid of any kind. Box furnace shutdown! Switch off the meter, and pull the power switch. When the box is higher than 400 ℃ Furnace open the door do not allow intense cooling. (2) the maximum temperature does not exceed the rated temperature. (3) installed furnace capacity is not too large, causing the temperature decrease should not exceed 50 ℃. (4) Do not use excessive force when you replace the furnace, so as not to damage the bottom. (5) whether the constant attention instrumentation and electrical control box electrical work.
