What are the reasons for the breakage of the coke oven frame and protective plate?

Causes of Coke Oven Frame and Protective Plate Breakage

Material Limitations

The materials used for coke oven frames and protective plates may not withstand long-term high temperatures. Thermal deformation can lead to breakage over time.

Uneven Furnace Expansion

Uneven expansion of the furnace body causes uneven stress on the protective plate and frame. This results in excessive local stress and potential fractures.

Steel Column Spring Control

Unreasonable tonnage control of the steel column springs causes uneven stress. This results in excessive local stress and breakage of the protective plate and frame.

Rapid Cooling and Heating

Heavy rainstorms can rapidly cool and heat the protective plate and frame. The sudden increase in internal stress can cause fractures.

Mechanical Impact

Impact from the furnace door or coke guide groove can create uneven stress. This uneven stress can break the protective plate and frame.

 

Improvement Measures

Use of High-Temperature Materials

Select materials that can withstand long-term high temperatures. Ensure that the coke oven frame and protective plates are made from high-quality, heat-resistant materials.

Monitor and Control Expansion

Regularly monitor the furnace body’s expansion. Implement control measures to ensure even expansion and reduce stress on the protective plate and frame.

Optimize Spring Tonnage Control

Ensure the steel column springs are properly calibrated. Maintain reasonable tonnage control to distribute stress evenly.

Implement Cooling Systems

Install systems to regulate temperature changes during heavy rainstorms. Gradual cooling and heating can prevent sudden stress increases.

Reduce Mechanical Impact

Ensure careful handling of the furnace door and coke guide groove. Implement protective measures to minimize impact on the coke oven frame and protective plates.
