Cntinuous Casting Process Of Low Carbon Low Silicon Steel

Low carbon silicon steel casting production has two main technical difficulties, namely control of carbon and silicon content, pouring of molten steel control. Based on the above, AnLing steel carbon low silicon steel casting production process were studied, mainly by controlling reasonable converter steelmaking, refining and casting process, including the control of composition, the degree of deoxidation, and other casting operations.By strict control of carbon steel, silicon content, and formulate suitable casting solution, through the use of aluminum wire, making it top slag modification difficulty can use aluminum wire section of top slag modification. After the casting of slab quality and qualified rate, and all kinds of problems and solutions encountered in the process, and final product quality and economic benefit.For the steel casting production of low-carbon low silicon, in order to produce acceptable quality low carbon silicon steel,it should control the content of carbon in 0.04%~0.06%,and silicon carbon in 0.03% to 0.05%;On the basis of controlling carbon and silicon content, it must be strictly controlled for hydrogen,nitrogen content, and Al2O3,(FeO+MnO) content in refining slag;Activity of [O] in steel should be controlled within a reasonable range. Proper deoxidation can avoid skin blowhole defects. Critical [O] activity of molten steel should be determined according to the composition of the steel. While weak deoxidation can reduces inclusions;Note the effects of pouring temperature, baking of ladle refractories and other operating factors, and take appropriate measures to reduce the steel composition segregation effectively.
