Description

Изобретение относитс к злетггрометаллургии, : а именно к энерготехнологическому режиму ведени плавки, и может быть использовадо дл выплавки стали в электродуговых нечах.The invention relates to zletgrometallurgy, namely, to the power technological mode of smelting, and can be used for smelting steel in electric arc furnaces.
Иэвестны способы выплавки стали в дуговых сталеплавильных печах (ДСП), вклютающие закалку металлошихты и шлакообразующих , когда проплавление колодцев и доплавление металла после образовани жидкой ванны ведут при заданном знерготехнологичес ком режиме Т.There are known methods for steel smelting in arc steel-smelting furnaces (DSP), including hardening of metal charge and slag-forming, when the melting of wells and the melting of the metal after the formation of a liquid bath are carried out at a given energy-technological mode T.
Известен способ выплавки стали в дуговых печах, содержащий завалку шихты с пода шлакообразующих на nojawv, проплавл колодцев и доплавление металла и шлака 121.There is a method of steelmaking in arc furnaces, containing the filling of the charge from the slag-forming hearth to nojawv, smelting wells and the melting of metal and slag 121.
Недостатком известного способа вл етс то, 410 в нем не предусмотрена регла в«ггаци энергетического режима, вследствие чего процесс шлакообразовани зат нут из-за необходимости проплавл ть в шихте несколько колодцев , а нагрев металла в период дшшавлени происходит недостаточно интенсивно и сопровождаетс повышенной облученностью футеоовки дугами.A disadvantage of the known method is that it does not provide for regulation in the “power mode” mode, as a result of which the slag formation process is slowed down due to the need to smelt several wells in the charge, and the metal is not heated enough during the period of pressure reduction and is accompanied by increased irradiance arcs.
Цель изобретени - повышение 1 юводительности печи и снижение и:зноса футеровки.,The purpose of the invention is to increase the kiln's kilowatt capacity and decrease the lining of the lining.
С этой целью предложен способ выплавки стали в дуговой электропечи, включаюцщй завалку шихты с подачей ишакообразующнх на подину, проплавлсние колодцев и до жтление металла и шлака при заданном эвергет ческом режиме Проплавление колодцев ведут за один проход злектродсж при отношении тока дуги к напр жению дуги 0,18-0,22 кА/В, For this purpose, a method of steel smelting in an electric arc furnace, including charging of the charge with supply of hearths for the hearth, melting of wells, and supplying metal and slag at a given evergetting mode, the melting of wells are carried out in one pass of electric arc with respect to arc current to arc voltage 0 18-0.22 kA / B

The total motion of the arc and the arc curve is maintained in the period before the metal and metal 45-60% higher than in the period {foshovlesh wells.
