Description
Известен способ десульфурации жидкого металла доменным шлаком. Известен также способ обработки доменного шлака газообразными реагентами.The known method of desulfurization of liquid metal by blast furnace slag. There is also known a method of treating blast furnace slag with gaseous reagents.
Дл создани высокоразвитой контактной поверхности шлак - чугун предлагаетс чугун, подвергаемый обработке, сливать в реторту конвертера на шлак, предварительно обессеренный в том же конвертере кислородом или газокислородной смесью.To create a highly developed contact surface, slag - cast iron is proposed to cast iron, which is being processed, to drain into the retort of the converter on the slag, which is presoaked in the same converter with oxygen or an oxygen-oxygen mixture.
В горловину конвертера вставл етс тигель с Перфорированным дном. Шлак подают в этот тигель из ковша по специальному желобу; он стекает в конвертер тонкими струйками навстречу восход ш,им нотокам кислорода, подаваемого через фурму. Затем шлак продувают газокислородной смесью дл нагрева и дальнейшей десульфурации. Стру чугуна с большой высоты сливаетс в конвертер на шлак, повыша контактный эффект смешивани и обессеривани .A crucible with a perforated bottom is inserted into the throat of the converter. Slag is fed into this crucible from a ladle through a special chute; it flows into the converter in thin streams towards the rising of w, to them a stream of oxygen supplied through the tuyere. The slag is then purged with an oxygen-oxygen mixture to heat and further desulfurize. The cast iron stream from a high height is poured into the converter onto the slag, increasing the contact effect of mixing and desulfurization.
Предмет изобретени Subject invention
Способ десульфурации чугуна доменным Н1лаком, отличающийс тем, что, с целью создани высокоразвитой контактной поверхности шлак - чугун, чугун сливают в конвертер на шлак, предварительно обессеренный в том же конвертере кислородом нли газокислородной смесью.The method of desulfurization of cast iron with domain H1lac, characterized in that, in order to create a highly developed contact surface, slag - cast iron, cast iron is poured into a converter into slag, previously desulfurized in the same converter with oxygen or an oxygen-oxygen mixture.
