A slag runner is an important component of a blast furnace operation. It is a trough or channel that is used to transport the molten slag away from the furnace to a slag pit or a slag granulation plant.
During the blast furnace process, various materials such as iron ore, coke, and limestone are melted at high temperatures to produce pig iron. The molten slag, which is a byproduct of this process, is collected at the bottom of the furnace and needs to be removed to prevent buildup and maintain efficient furnace operation.
The slag runner is typically made of refractory material that can withstand high temperatures and the corrosive properties of the slag. It is designed to have a gradual slope and a sufficient width to allow for the smooth flow of the molten slag. The slag runner can also have various features such as weirs and dams to control the flow of the slag and prevent splashing.
Efficient operation of the slag runner is critical for the overall efficiency and productivity of the blast furnace process. Any blockages or disruptions in the slag runner can result in reduced production rates and potential damage to the furnace. Therefore, besides regular maintenance and monitoring of the slag runner, reliable quality of the slag runner is also essential to ensure smooth and uninterrupted operation.
