Description
Изобретение отиоснтс к металлургии, в частности к выплавке сплавов па никелевой осиове.The invention of otiosnts to metallurgy, in particular to the smelting of alloys PA nickel axis.
Известен способ выплавки сплавов методом переплава легированных отходов или сплавлением свежих материалов (пикел и хрома) в открытых дуговых печах с применением в качестве раскислител кальци и его сплавов.There is a known method of melting alloys by melting alloyed waste or by fusing fresh materials (pickle and chromium) in open arc furnaces using calcium and its alloys as a deoxidizing agent.
Такой способ выплавки характеризуетс невысокой те.хиологической пластичностью отдельных илавок и повышеппым угаром хрома.This method of smelting is characterized by low teh.ologicheskoe plasticity of individual wells and chromium.
По предложенному способу раскисление ванны кальцием осуществл ют в печи перед вводом хрома.According to the proposed method, the deactivation of the calcium bath is carried out in a furnace before the introduction of chromium.
Благодар это.му повышаетс технологическа пластичность сплава и спилсаетс угар хрома.Thanks to this, the technological plasticity of the alloy is improved and the waste of chromium is reduced.
В сталеплавильном агрегате расплавл ют 1иихту, состо щую из никел или отходов еплава и пикел . Шлак раскисл ют смесью кокса и еилпкокальци , а металл - поверхностпо-активпымп элементами, например кальцием, вIn the steelmaking unit, the melt of the primary alloy consisting of nickel or heat of the melt and the pickle. Slag is deoxidized with a mixture of coke and eelcoccalcium, and the metal is oxidized by surface-active elements, such as calcium, in
количестве 0,3-2 кг/г. Затем присаживают в смеси с техническим глиноземом (5-8 кг/т} нагретый металлический хром (феррохром дл силаво типа Х15Н60). После расплавлени хрома, проверки пластичности металла провод т избыточное раскисление расплава кальцием или спликокальцием (дл получени хорошей и,1астпчности при гор чей деформации слитков), и п.чавку выпускают из печи.the amount of 0.3-2 kg / g. Then heated metallic chromium (ferrochrome for silavo type X15H60) is mixed with technical alumina (5-8 kg / t). After the chromium is melted, the plasticity of the metal is checked by excessively deoxidizing the melt with calcium or splicing (to get good and whose deformation of the ingot), and p.chavku released from the furnace.
