Изобретение относитс к черной металлургии , в ча1СТ1Ности к вьшлавже стали с обработкой сиитетическим шлаком в ковше.The invention relates to ferrous metallurgy, in particular, to the production of steel with the treatment with a sietitic slag in a ladle.
Известен способ выплавки стали и сплавов, при котором одновременпо с -обработкой синтетическим шлаком в ковше металл раскисл ют редкоземельными элементами. Однако введение редкоземельных элементов -в металл одновременно с обработкой шлаком в ковше приводит к ухудшению микроструктуры деформируемой стали из-за образовани в ней сколлений сульфидов и оксисульфидов, так называемой «периевой пористости.There is a known method of smelting steel and alloys, in which, simultaneously with the processing of synthetic slag in a ladle, metal is dissolved by rare-earth elements. However, the introduction of rare earth elements into the metal simultaneously with the treatment of the slag in the ladle leads to a deterioration of the microstructure of the deformable steel due to the formation of splitting of sulfides and oxysulfides in it, the so-called "perimeter porosity."
Цель .изобретени - снижение загр зненности металла крупными глобул рными включени 1М1И , улучшение его .макроструктуры -и механических свойств. Это достигаетс введением редкоземельных элементов непосредственно во врем разливки стали после ее рафинировани синтетическим шлаком.The purpose of the invention is to reduce the contamination of the metal with large globular inclusions 1M1I, and to improve its macrostructure and mechanical properties. This is achieved by introducing rare earth elements directly during the casting of steel after refining it with synthetic slag.
Редкоземельные элементы присаживаютс во врем разливки в количестве, например, 0,8-2,0 кг/т стали.Rare earth elements are set down during casting in amounts of, for example, 0.8-2.0 kg / ton steel.
Предмет изобретен и- The subject invented and
Способ производства стали, включаюш,ий обработку металла синтетическим шлаком и редкоземельными, элементами, отличающийс тем, что, с пелью снижени загр зненности металла крупными глобул рными включени ми , улучшени его макроструктуры и механических свойств, редкоземельные элементы ввод т непосредственно во врем разливки стали после ее рафинировани сиитетическим шлаком.The method of steel production, including metal treatment with synthetic slag and rare earth elements, characterized in that, with a reduction in the contamination of metal with large globular inclusions, improvement of its macrostructure and mechanical properties, rare earth elements are introduced directly during steel casting. its refining by sithitic slag.
