Product Description

SGR type SiC heating elements This high-density SGR double-spiral silicon carbide heating element is cut so as to place both electrical terminations on the same end of the element. They are supplied with the terminal assembly attached. SGR type Zhok silicon carbide heater is used where furnace design or dimensions preclude wiring from both sides of the furnace. This type is ideal for blind holes and insertion in tubes. For maximum performance can up to 1650 deg C. 

 

The general introduction of SiC heating element and accessories! 

1. The silicon carbide heating element is a kind of non-metal high temperatureelectric heating element. 

2. SiC heating element. 

1) Main type: ED (straight ), DB (thin and thick ), Sg(single thread), SgR(double thread ), U, W, UX. 

2)We can provide the dimension as per your requirement. 

3. Some specific: Low expansion coefficient, little deformation, stable chemical property, long service life, easy installation and maintenance. 

4. It is extensively used in the fields of metallurgy, ceramics, glass, machinery, analysis test semiconductor science and research. 

5. Installation and operation of elements 

1). In order to keep furnace temperature and the load-bearing uniform of each element, before installation, resistance distribution must be carried out. The resistance value deviation of each group should be below 10%. 

2). As the element is very brittle, be careful while install and maintain to avoid any damage. 

3). When start to operate the furnace, raise voltage slowly and gradually, never give full load at one time, or the heating element will be damaged by over current impulse. 

4). To use the elements, you should prepare the adjustable transformer or silicon controlled transformer, voltage meter, current meter and auto-control temperature meter etc. During the working, the voltage should be increased to maintain the furnace normal temperature because the resistance value will go up gradually caused y the oxidation of element. When the voltage get to the up limit of the requirement, the furnace should be stopped, change the way of wire connection and then continue work. 

5)...In the course of long operation of the furnace, if any individual heating element is damaged owing to certain reasons and should be changed, you should replace it with proper one whose resistance value corresponds to that of the old one, never use a new heating element random. If the heading element is much damaged or its resistance value increases too much and cannot reach the furnace temperature, it is better to replace the heating elements with mew ones. Test and mark the resistance value of the old elements having been replaced (with voltmeter and ammeter) and distribute them in low temperature area. 

6). Before the new furnace of the furnace that has not been used for a long time is used, they must be dried. When drying them, it is better to use old elements or other heat source. 

7). When firing products or material, if there is water ejection, the furnace should have holes to eject water vapor or other waste gases in order to protect the elements service life.
