The blast furnace outlet pipe is turning red; it’s too dangerous

The redness of the furnace outlet pipe may be caused by excessive pipe temperature; this is a dangerous situation that requires measures to avoid potential accident risks. Firstly, considering increasing the cooling measures for the pipes, such as raising the flow rate and pressure of cooling water or other cooling media, can help lower the temperature of the pipes. Secondly, considering changing the material of the pipeline, materials resistant to high temperatures such as alloy steel and nickel-based alloys can be chosen to improve the pipeline’s resistance to high temperatures. Furthermore, insulation measures for the pipes can be added, such as installing insulating materials, to reduce heat loss and lower the pipe temperature. Additionally, if the pressure at the furnace outlet is too high, it may also cause the pipes to turn red; it is necessary to check whether the pressure control system is functioning properly and to adjust it to an appropriate pressure range. In summary, to address the problem of redness in the furnace outlet pipeline, it is necessary to take into account factors such as pipeline cooling, material selection, insulation measures, and pressure control, and to develop appropriate renovation plans based on the specific circumstances. It is recommended that you consult a professional engineer or technician for a detailed evaluation and guidance. .
