Description

Technical Field

[0001] The utility model relates to the technical field of steel production equipment, in particular to a cooling device for a gas cut-off valve and a ladle roaster. Background Art

[0002] Ladle baking is one of the main links in the steelmaking production process. The purpose of baking is to evenly increase the temperature level of the ladle lining to reduce the heat loss during the molten steel pouring process and extend the service life of the ladle lining. The performance of the baking device has a great influence on the converter tapping temperature, steelmaking operation rate, furnace life, etc. Ladle baking is between the two processes of steelmaking and steel casting. The high or low temperature of the ladle baking plays an important role in coordinating the entire production, and is even more significant for continuous casting production. Molten steel must be calmed in the ladle for 5 to 10 minutes from the completion of steel tapping to pouring before pouring. During the calming process, the temperature of the molten steel will decrease. There are three main heat energy losses: heat loss on the upper surface of the molten steel, comprehensive heat loss on the surface of the ladle shell, and heat loss of the ladle lining. The heat loss of the ladle lining accounts for about 40% to 50% of the total heat loss. Therefore, reducing the heat loss of the ladle can greatly reduce the temperature drop of the molten steel in the ladle. It is of great significance to reduce the steel tapping temperature, prolong the life of the converter, increase steel production, reduce the consumption of raw materials, reduce the cost per ton of steel, and ensure the smooth progress of continuous casting.

[0003] At present, the ladle roaster is mainly composed of air inlet pipe, gas inlet pipe, gas shut-off valve, mixed gas chamber, burner, guide plate, air purification device and other equipment; however, in actual work, the high temperature generated by the ladle roaster affects the gas shut-off valve on the air inlet pipe and the gas inlet pipe, which can easily cause the gas shut-off valve to fail, posing a safety hazard.
