Description

Изобретение относитс  к металлургическому производству, в частности к составам шлакообразую щих и эквотер1жческих смесей дд  защиты зеркала металла при разлив ке стали в изложницы.The invention relates to metallurgical production, in particular, to compositions of slag-forming and equothermic mixtures for the protection of a metal mirror during casting of steel into molds.

Известны шлакообразующие материалы и экзотермические смеси, примен емые дл  защиты зеркала металла при разливке стали и содержаище окислы бора. Однако известные материалы и смеси тугоплавкие . Ьто сужает возмсжность и эффективьоить их применени  в тех случа х, когда на поверхности слитка ну}шо получить более плотный шлаковый слои,Slag-forming materials and exothermic mixtures used to protect the metal mirror during the casting of steel and boron oxides are known. However, the known materials and mixtures are refractory. This narrows down the possibilities and their effective use in cases where, on the surface of an ingot, well, you can get more dense slag layers,

С целью обеспечени  образовани  жидкого шлака на зеркале расплавленной стали при разливке ее в изложницы и равномерного шлакового сло  (гарнисажа) по всей высоте олитка в качестве предуюженного шлакообразующегоIn order to ensure the formation of molten slag on the mirror of molten steel when casting it into molds and a uniform slag layer (skull) over the entire height of the mold as a preduged slag-forming
