Product Details
Precast Coke Oven Door for Sale
Description
The surface of pre-cast refractory door is made of composite ceramic material. Pre-cast refractory is shaped by high frequency vibration. The unformed material has low porosity, high density and good uniformity. There is crystalline ceramic refractory adhere the pre-cast surface, which have high strength, good abrasion resistance and corrosion resistance. It has been reduced the physical damage during the operation and tar and other chemicals erosion to the refractory.
Features
1.Simple structure and easy to install.
2.Good integrity and impermeability.
3.Longer working life than the traditional one.
4.Energy-saving and environment-friendly.
Application
It’s mainly used for the coke oven.

Comparison between new type and traditional type:
| New type pre-cast coke oven door | Traditional oven door |
|---|---|
| Easy to install | The oven door installation is very complicated. |
| The fastening bolts have been inserted in the precast. The precast oven door is clamped to the door structure directly by that bolts. | |
| The oven door is more air impermeability. | Traditional oven door has more joints. The joints are easy to become bigger owing to long time mechanical operation. |
| The new type oven door consists of 6 or 7 precast refractory glazing crystalline ceramic refractory surface. | The air impermeability and insulating ability is worse. Heat loss, gas leakage and environment pollution are more serious. |
| The whole oven door exist 5 or 6 joints. | |
| Crystalline ceramic refractory glaze have high refractoriness, good bonding performance and malleability, good thermal shock resistance. During the operation, the glaze have good spalling resistance under rapid variation of temperature. | The raw materials of traditional door don’t have good mechanical strength and thermal shock resistance. |
| Long-life | Short-life |
| The maintenance times and costs are reduced, and the labor cost is decreased 70%. | Frequent repair and maintenance cost is high. |
| Energy-saving and environment-friendly | Energy consumption and environment pollution |
| Good heat insulation | Gas leakage |
| Less heat loss | Yellow smoke |
| Improve the carbonation rate | Heat dissipation |
