Description

Изобретение относитс  к способам предохранени  металлической шихты чугуна в вагранках. Известные способы, например добавка к известковому камню или мелу плавикового шпата в качестве флюса, неудобны в практическом использовании из-за разъедани  футеровки сильно действующими основными флюсами.This invention relates to methods for protecting a metal charge of cast iron in cupolas. Known methods, such as addition to limestone or fluorspar chalk as a flux, are inconvenient in practical use due to corrosive lining with highly active basic fluxes.

Дл  устранени  указанного недостатка предлагаетс  металлические куски шихты покрывать смесью мела и графита, разведенных водой, а затем подвергать их сушке. При плавке в вагранках чугун насышаетс  серой в твердом состо нии во врем  нагрева до высоких температур и в жидком расплавленном состо нии при взаимодействии с коксом . Предлагаемый способ обеспечивает предохранение шихты в твердом состо нии. Дл  этой цели на поверхность кусков металлической шихты, представл ющей собой штыковой чугун, стальной и чугунныйIn order to eliminate this drawback, it is proposed to cover the metal pieces of the mixture with a mixture of chalk and graphite diluted with water, and then subject them to drying. When smelting in cupolas, the iron becomes saturated with sulfur in the solid state during heating to high temperatures and in the molten liquid state when interacting with coke. The proposed method provides protection of the charge in the solid state. For this purpose, the surface of pieces of metal charge, which is a bayonet cast iron, steel and cast iron

лом и ферросплавы, наноситс  защитное покрытие из мела и графита, преп тствующее контакту материала шихты с газообразными сернистыми соединени ми. Как показала опытна  проверка предлагаемого способа, применение защитных покрытий на кусках шихты позволило снизить содержание серы в готовом чугуне с 0,12 до 0,05%. Способ может быть использован также при переделе чугуна на сталь, особенно на машиностроительных заводах, где примен етс  такое конвертирование.scrap and ferroalloys, applied a protective coating of chalk and graphite, preventing contact of the charge material with gaseous sulfur compounds. As shown by an experienced test of the proposed method, the use of protective coatings on pieces of the charge made it possible to reduce the sulfur content in the finished iron from 0.12 to 0.05%. The method can also be used in the conversion of pig iron to steel, especially in engineering plants where such conversion is used.

Предмет изобретени Subject invention

Способ предохранени  металлической шихты от насыщени  серой прм плавке в вагранке, отличающийс  тем, что дл  защиты кусков шихты от газообразных сернистых соединений , поднимающихс  по щахте вагранки, металлические куски шихты покрывают смесью мела и графита , разведенных водой, а затем подвергают сушке.A method of protecting the metal charge from saturation with gray smelting in a cupola, characterized in that to protect the charge pieces from gaseous sulfur compounds rising along the bottom of the cupola, the metal charge pieces are covered with a mixture of chalk and graphite diluted with water and then dried.
