Slag pot is an important device in steel making. It is a load-bearing device to collect molten or solid slag generated during metallurgical or chemical processes. The steel mill equipment is a bowl-shaped container with lifting lugs at both sides. A grilling is installed inside the pot, under at least 300mm of the upper surface and divides the inner pot into some pieces. The slag pot that purchased by metallurgical enterprises generally is made by traditional cast process with long manufacturing cycle, short service life, and great scrapped quantity. Chaeng, through continuous technical innovation in production process, makes slag pots that have more advantages such as short cast period, long service life and strong resistance to deformation.
