Product Description:
The Slag Pot is an important equipment in steelmaking production. It is a container for high-temperature
slag produced during the smelting process of steel. It has a bowl-shaped container with lifting trunnions
on both sides.
Slag Pot purchased by metallurgical companies generally use the traditional casting process, which has
a long manufacturing cycle, short service life, and a large number of scraps. Great Wall Cast Steel has
increased innovation in the production of slag tanks, and its slag tanks have a short casting period and
a long service life Strong anti-deformation ability.
The Trends for Material Selection:
Due to obvious advantages in terms of service life,maintenance and cost-efficiency, cast steel has been
becoming more significant in the melting pot construction over the last few years against both materials,
spheroidal cast-iron and lamellar graphite cast-iron. In comparison with other materials, cast steel offers
excellent repair possibilities as it is well-suited to welding.
