Graphite Carbon Sleeves
Graphite Carbon Sleeve
The GAP is our general application carbon sleeves with CIP base materials after chemical treatment, It has been widely used in Wuhan Steel and Bao Steel and other steel mills inside and China and out side of China.he ECP is our high value added carbon sleeves by special coating on C IP graphite. The coating forms a dense, impervious layer, inhibiting chemical reaction on the surface of graphite with atmosphere inside the furnace. It is suitable for high-temperature crystal growth scenarios in side the CAL of silicon steel. It is desined for 1200℃ above CAL.The ANP is extremely dense and smooth carbon sleeves with excellent thermal stability and good heat shock resistance. It is designed for the CAL manufacturing high grade non-oriented silicon steel for EV motors. It can reduce the nodulation on the surface of carbon sleeves dramatically.

Process Flow Diagram
Graphite carbon sleeve of inspection standard
1, Appearance standards: surface roughness is less than 6 .2 μm, the flatness and size meet specific customers requirements .
2, Machining operations are performed strictly according to the drawings .
Operating guide
1, carbon sleeve is fragile items, handling process to fine operation.
2, regularly check the flatness of the steel shaft, if there is bending, to replace as soon as possible.
3, above 400℃, graphite products begin to oxidize, so in the use of inert gas protection.
4, keep the furnace clean, dust and inclusions can lead to carbon jacket surface nodules.
