Silicon carbide (distributed around the hearth or around) the carbon rod is the choice of high-quality green silicon carbide as the main raw material, processing system bah light, temperature silicification, in non-metallic rod made of high-temperature heating elements crystallize. Compared with the element metal heating element, with the use of high temperature, anti-oxidation, corrosion resistance, long life, micro deformation, easy installation and maintenance. Silicon carbide having a large specific resistance, heated in air, the surface temperature of the heat generating portion can reach 1450 ℃; from room temperature to 800 ℃ is negative, a positive value above 800 ℃ characteristic curve. Maintenance 2.1 controller should be placed on dry well-ventilated, non-corrosive gases laboratory furnace, the working environment temperature -10-50 ℃, relative humidity less than 85%. 2.2 To ensure accurate measurement, the annual application of DC potentiometer proof of XMT-type temperature controller temperature table, in order to avoid large errors. 2.3 regularly check whether the various parts of the wiring is loose, AC contactor contacts is good. Malfunction should be repaired. Parameter 1, control: SCR control, PID parameters self-tuning function furnace temperature controller, manual / automatic switching function without interference, over-temperature alarm function. 2, the furnace material: special ceramic fiber furnace, heating speed, good insulation effect. 3, the display window: temperature measurement, dual display set temperature, the heating power beam display.
