Sic Silicon Carbide Crucibles for Melting Steel

Introduction:

Taking the latest isostatic molding method and strict quality assurance inspection system, we use advanced refractory materials, high-tech formula to develop a new generation of high-strength silicon carbide crucible, this product gets a feature

of large volume density, acid erosion, high temperature strength, high temperature strength and long service life is 3-5 times the clay graphite crucible.

Some choices:

How to prolong life-span of crucible?

1.Stored in the dry warehouse, kept from moisture

2. Scrolling and wrestling shock is prohibited, so as not to damage the protective layer of the crucible

3. Baking prior to the use of the crucible, baking temperature rise to 500 degrees Celsius slowly and constantly, heat evenly to remove the water in the body of crucible (if pre-heat improperly, crucible peeling , cracking will occur )

4. The crucible should match with the crucible furnace; the lid on the pot can not be pressed

5. Flame should be sprayed to the crucible base instead of crucible body

6. Feeding slowly, not too much, too tight, so as not to split up the crucible

7. Better used continuously, so as to get better high performance

8. Pay attention to that the amount of the additive into the smelting process, excessive use will reduce the life span

9. Rotating the crucible periodically to heat evenly

10. The crucible slag and coke should be removed often 

Application:

Silicon carbide crucible can smelting all kinds of gold, silver, copper, aluminum, lead, zinc and other non-ferrous metals,medium carbon steel, all kinds of rare metal and carbon products manufacturing.

Suitable for furnace, electric furnace, medium frequency furnace, high frequency furnace.
