Continuous Casting of High Al Steel in Shougang Jingtang

Continuous Casting of High Al Steel in Shougang Jingtang

Nov 01, 2015· Simultaneously, the new mold pow der melts into liquid slag and repeats the process of mold 55 Continuous Casting of High Al Steel in Shougang Jingtang Steel Works powder melting, slag/metal reaction, surface renewal, and mold powder consumption. Finally, a balance is reached and the mold powder composition becomes stable.Continuous Casting of High Al Steel in Shougang Jingtang The high Al content Al TRIP steel is likely to react with SiO 2 in the mold slag during the continuous casting process, which leads to a rapid increase of Al 2O 3 content in the slag from 3% to 30%.Continuous casting of high Al steel in shougang jingtang Nov 01, 2015· Reaction between mold flux and liquid high aluminum steel is considerably strong. It changes the physical property of the mold powder greatly and leads to a larger fluctuation of heat flux in the mold. Transverse depression and longitudinal cracks were often found on the slab surface. Three casting trials were carried out to investigate the effects of mold powder and slab width on castability

Formation of Surface Depression during Continuous Casting

The surface of the slab is prone to depressions and longitudinal cracks during continuous casting due to the high Al content in steels.

Inclusion behaviour in aluminium killed steel during

The inclusion behaviour during continuous casting were investigated in ultra low carbon (ULC) and high strength low alloy (HSLA) steels. From tundish to cast slabs, the total oxygen (T.O) content decreased from 19 to 12 ppm, 12 to 11 ppm in ULC steel and HSLA steel, respectively.Clean Steel Scientific.NetA review on functions is also made which of high efficiency, low cost and high quality steel products manufactured by the new generation iron and steel plant, in combination with the study on design of steelmaking continuous casting process of Shougang Jingtang iron and steel plant.US20090246068A1 Refinement of steel Google PatentsA method of forming and refining molten silicon bearing steel by addition of a calcium containing silicon additive. Determine if the amount of calcium in the calcium containing silicon additive is more or less than the amount of calcium desired in the finished steel. If it is more than the amount of calcium desired in the finished steel, add the amount of calcium containing silicon additive
