Both ferrous and non-ferrous metallurgical enterprises produce a large amount of high-temperature liquid slag, and the vast majority of steel furnace manufacturers use slag bags (or slag pot and slag tanks) to load and process slag. Before the birth of welding slag ladle technology, users used casting slag ladle to treat furnace slag. After the birth of welding slag ladle, compared with casting slag ladle, the slag pot carrier embodies significant advantages such as stable quality, low maintenance rate, good weldability, and high cost-effectiveness.
