H Type Globar SiC Heating Elements/SiC Heater/Silicon Carbide Heating Elements

H Type Globar SiC Heating Elements/SiC Heater/Silicon Carbide Heating Elements    Product Description The silicon carbide (sic) heating element is a kind of non-metal high temperature electric heating element. it is made of selected super quality green silicon carbide as main material ,which is made into blank, solid under high temperature and re-crytallized. compared with metal electric heating elements, this elements is characterized by high-applied  temperature, anti-oxidization, anti-corrosion, long service life, little deformation ,easy installtion,long service life,little deformation,easy installation and maintenance. Therefore, it is widely used in various high temperature electric furnaces and other electric heating devices, such as in the industries of magent, ceramics, powder metallurgy ,glass, metallurgy and machinery etc.     we make Rod type(ED type), Dumbbell type (DB type), U type, W type (Three Phase type), door-like type, gun type, H type or according to your requirement.    Reference Data

              Accessories  and installation                                                                                       Support clamp are applied to 9/18 and 6/12 two kinds of elements respectively. the support clamp supports the whole weight of the element and the position of the element is also determined by it .therefore ,it must be installed carefully to assure that the element it vertically hung.in order to prevent the element from being over heated locally,the taper part of the element lower end must put into the furnace chamber.       Attention   a)Heater should be protected against damp during storing or installing to ensure the performance of the heater.   b)In order to be sure of well~distributed load of each and groups heater should be divided before assembling.   The tolerance of the resistance of each one can not exceed by 10% each other.   c)Heater is hard and brittle, please be careful when assembling and maintaining so as to avoid damage.   d)When operating the electric furnace at the beginning, the voltage should be increased slowly and can not be fully loaded at once. Otherwise the larger current will be resulted in the damage of heater.   e)When heater is damaged and need to be changed , the resistance of new heater should follow the increasing resistance. If many are damaged or resistance increased too much, all the heater should be changed.     Company Information    Our factory have more than 20 years production experience, specialized in manufacturing high-temperature heating elements with strict quality control system, advanced equipment, strong technique power and complete test facilities.
