Description

Technical Field

[0001] The utility model relates to the technical field of heat-insulating electric furnaces, in particular to a blast furnace slag granulation and slag storage heat-insulating electric furnace. Background Art

[0002] Slag granulation is the process of quenching the molten material produced during pig iron smelting in a blast furnace, preventing it from crystallizing and forming fine particles. The result is granulated blast furnace slag, an important industrial solid waste with potential hydraulic gelling properties. This not only enables waste resource utilization but also has a wide range of applications in the building materials sector, playing a significant role in promoting the development of a circular economy and environmental protection.

[0003] After slag granulation is completed, an insulating electric furnace is needed to store and insulate the slag to ensure that the slag maintains its characteristics at a specific temperature for subsequent processing or utilization. Before the slag is poured into the insulating electric furnace, the insulating electric furnace needs to be preheated in advance. However, when the slag is poured into the insulating electric furnace from the feed port, the feed port is in a normally open state, which leads to the loss of preheating heat and dissipation from the feed port, thereby increasing the cost. In response to the above problems, the inventors proposed a blast furnace slag granulation storage slag insulating electric furnace to solve the above problems. Utility Model Content
