The important role of ladle roaster in the transfer of molten steel/iron

Date:2022-08-11Author:Fuxingda Environmental EquipmentHits:487

Hot metal ladle baking is one of the important work links in steelmaking process. The ladle roaster is mainly used to quickly heat up the hot metal ladle of cold repair, new construction, drying and turnover of molten steel. The performance of the ladle roaster has a great influence on the steelmaking operation rate, molten steel tapping temperature, furnace life, etc. The ladle baking device is used to bake the molten iron ladle between steelmaking and continuous casting. The ladle baking temperature plays an important coordinating role in the whole production, especially in continuous casting production

During the operation of molten steel from the steelmaking production process to the continuous casting process, the molten steel will lose a lot of heat energy. If the ladle is not baked, the temperature of the ladle before the molten steel is injected will be increased to compensate the heat energy loss of the molten steel and ensure the temperature of the molten steel during pouring. To increase the tapping temperature, it is necessary to continuously increase the smelting production time, increase the consumption of raw material resources of enterprises, increase the cost per ton of steel, so that the development speed of furnace lining erosion can be accelerated and the furnace life can be reduced. Therefore, improving the baking environment temperature of ladle is of great significance to reduce the tapping temperature and the consumption of raw material resources of enterprises

The gas-fired bag-taker is mainly composed of a bag cover, a combustion-supporting fan, a support mechanism, a control system, a combustion-supporting air pipeline system, a fuel sub-pipeline system, a fuel injection pipeline system, and a transfer car
