Product Description

Detailed introduction to gun-type silicon carbide heating element: yuhao sic u-type heating elements consist of two silicon carbide legs of equal diameter. each leg is divided into two parts ,hot zone and cold end with a joint.the resistance of both legs are equal to ensure a uniform performance.both shanks are joint with a crossbar made of low resistance.thus,it can be used as an end support,if required. notes for using and installing the heater: 1. heater should be protected against damp during storing or installing to ensure the performance of the heater. 2. in order to be sure of well-distributed lod of each and groups, heater should be divided before assembling. the tolerance of the resistance of each one cannot exceed by 10% each other. 3. heater is hard and brittle, please be careful when assem bling and maintaining so as to avoid damage. 4. when operating the electric furnace at the beginning, the voltage should be increased slowly and cannot be fully loaded at once. otherwise the larger current will be resulted in the damage of heater. 5. when heater is damaged and need to be changed, the resistance of new ne should follow the increasing resistance. if many are damaged or resistance increased too much, heater should be changed. 6. silicon carbide (sic) heating elements is a non-metal electric heating element made from sic as its main raw materials. it has some specific properties, such as low expansion coefficient, little deformation, stable chemical property, long service life, easy installation and maintenance, etc. 7. usage: silicon carbide (sic) heating elements can usually make use for furnace which temperature from 600-1600. it can be directly used in an air atmosphere, without any protection atmosphere. it is extensively used in the fields of metallurgy, ceramics, glass, machinery, analysis test, semiconductor, science & research and so on.
