Product Introduction
New type coal-charging hole precast has high strength, low thermal conductivity, and good abrasion and erosion resistance. Reduce physical damage and tar and other chemical erosion for the refractory during operation. The working life is up to three years.
Features
1. Long working life.
2. Self-cleaning function.
3. Keep the working area clean.
4. More match with the lid, reduce gas leakage, yellow smoke and pollution.
5.Can improve the oven roof working condition.
Application
It's mainly used for coke oven.

Comparison between new type and traditional type
|
NEW TYPE |
TRADITIONALTYPE |
|
High performance crystalline ceramic refractory materials cover the working surface. |
Iron casting |
|
Good thermal insulation |
Poor thermal insulation |
|
No coal and coke deposition, self-clean function |
Easy to be magnetized, leading to accumulate dust. |
|
The maintenance frequency can be significantly reduced. Keep the working area clean. |
Frequent repair and high maintenance cost. |
|
Match with the lid; reduce gas leakage, yellow smoke and pollution, improving the oven roof working condition. |
Gas leakage |
