Изобретение относитс к металлургии, в частности к разливке стали под смес ми.The invention relates to metallurgy, in particular to the casting of steel under mixtures.
Известна экзотермическа смесь, содержаща силикатную глыбу, плавиковый шпат и нефелин.A known exothermic mixture containing silicate lump, fluorspar and nepheline.
Дл ускорени формировани шлака в предлагаемую смесь дл разливки стали введен древесный опил при следующем соотношении компонентов, вес. %:To accelerate the formation of slag, wood sawdust was introduced into the proposed mixture for steel casting in the following ratio of components, weight. %:
Плавиковый шпат19-53Fluorspar19-53
Нефелин8-38Nefelin8-38
Силикатна глыба8-38Silicate Cluster8-38
Древесный опил23-37Woody sawdust 23-37
Смесь готов т смешением компонентов, вз тых в порошкообразном виде. Ее ввод т перед началом разливки в неокрашенные изложницы в бумажных пакетах. После заливки в прибыль ввод т утеплительный материал. При контроле макроструктуры стали, отлитой подThe mixture is prepared by mixing the components taken in powder form. It is introduced before pouring into unpainted molds in paper bags. After pouring, the insulation material is introduced into the profit. By controlling the macrostructure of steel cast under
смесью, дефектов на уровне 12% отреза не обнаружено.a mixture of defects at the level of 12% of the cut is not detected.
Смесь дл разливки обеспечивает быстрое формирование шлака, сохранение его жидкотекучести в процессе разливки, улучшение поверхности слитка, сокращение брака и снижение расхода металла на прибыль.The casting mixture ensures the rapid formation of slag, the preservation of its fluidity in the casting process, the improvement of the ingot surface, the reduction of scrap and the reduction of metal consumption for profit.
