Ascending Pipe Pre-cast Refractory
Capacity:500 tons per month
Color:White
Size:As your requirements
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.

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. |
