Abstract
Способ внепечной обработки стали, включающий наведение высокоосновного шлака, раскисление стали алюминием, продувку аргоном расплава металла и ввод кальцийсодержащих материалов в два этапа, отличающийся тем, что первую порцию присаживают по приходу металла на внепечную обработку с расходом, определяемым из выраженияQ=-4,172×Si-0,0152×О+0,106×h-2,16,где Q- расход кальция, кг;Si - содержание кремния в пробе металла перед отдачей кальция, %;О- окисленность металла по приходу металла на установку печь-ковш;h- толщина шлака, мм.4,172; 0,0152; 0,106; 2,16 - эмпирические коэффициенты, полученные опытным путем,затем металл подвергают доводке по химическому составу, вторую порцию кальцийсодержащих материалов вводят перед отдачей металла на МНЛЗ с расходом, определяемым из выраженияQ=297,17×S+6,94×Si+2040×Al-0,857,где Q- расход кальция, кг;S - содержание серы в пробе металла перед отдачей кальция, %;Si - содержание кремния в пробе металла перед отдачей кальция, %;Al - содержание алюминия в пробе металла перед отдачей кальция, %;297,17; 6,94; 2040; 0,857 - эмпирические коэффициенты, полученные опытным путем.A method of out-of-furnace steel processing, including guidance of highly basic slag, deoxidation of steel by aluminum, argon purging of a metal melt, and introduction of calcium-containing materials in two stages, characterized in that the first portion is seated upon the arrival of the metal in the out-of-furnace treatment with a flow rate determined from the expression Q = -4.172 × Si -0.0152 × O + 0.106 × h-2.16, where Q is the calcium consumption, kg; Si is the silicon content in the metal sample before calcium output,%; O is the oxidation of the metal upon metal arrival to the ladle furnace; h - slag thickness, mm. 4.172; 0.0152; 0.106; 2.16 - empirical coefficients obtained experimentally, then the metal is subjected to refinement by chemical composition, a second portion of calcium-containing materials is introduced before the metal is returned to the continuous casting machine with a flow rate determined from the expression Q = 297.17 × S + 6.94 × Si + 2040 × Al-0.857, where Q is the consumption of calcium, kg; S is the sulfur content in the metal sample before the release of calcium,%; Si is the silicon content in the metal sample before the release of calcium,%; Al is the aluminum content in the metal sample before the release of calcium,% ; 297.17; 6.94; 2040; 0.857 - empirical coefficients obtained experimentally.
