The function of the tension leveler The arc continuous casting machine is the main force in the production of cast billets in the iron and steel industry. Square billets, rectangular billets and round billets are generally produced by arc continuous casting machines, occupying a dominant position, even if the continuous casting machine adopts a straight…
The generation mechanism of the slag circle: The temperature of the protective slag at the meniscus near the slag crystallizer is only 1200~1300°C, and so-called slag circles often appear during casting. The formation of the slag ring is caused by the adhesion of the sintered layer and the semi-molten layer of the mold slag in…
The casting billet with a liquid core coming out of the mold, under the action of bending, straightening or wheel pressure, produces cracks at the solidifying, very fragile solid-liquid interface, called internal cracks. Such internal cracks can be severely visible to the naked eye through acid leaching and sulfur mark tests of cast billet samples.…
