Product Introduction
The lining of ascending pipe upper structure is made of monolithic casting refractory; bottom structure is made of high temperature glazed refractory. There is less carbon deposit on the surface of the pre-cast refractory. New type pre-cast plays a very good role in thermal insulation.
Features
1.Smooth surface.
2.Simple structure.
3.Long working life.
4. Energy saving.
Application
It's mainly for coke oven.

Comparison between new type and traditional type
NEW TYPE | TRADITIONAL TYPE |
Smooth surface, less joints, less carbon and dust deposition | Traditional ascending pipe is installed by refractory bricks, after installation, the surface is rough and has many joints. It is easy to accumulate coal and dust. |
Simple structure New type consists of three parts: glazed base, glazed bottom pipe, monolithic casting upper pipe. | Complicated structure |
Easy to install the ascending pipe, using the bolts to link the three parts. | Complicated installation |
Reduce the repair times and save the cost. | Frequent repair and high cost |
Long working life | Short working life |
Solve the gas leakage problems, reduce the environment pollution and heat dissipation, lead to energy saving. | Long time mechanical operation and chemical damage on the joints, leading the joints to become bigger. Gas leakage and environment pollution. |
