Description
кремний 1,4 и 0,3; железо 8,7 и 7,2; фосфор 0,088-0,07; углерод 0,12 и 0,11.silicon is 1.4 and 0.3; iron 8.7 and 7.2; phosphorus 0.088-0.07; carbon 0.12 and 0.11.
В плавках первой серии используют силикомарганец Запорожского ферросплавного завода , а второй серии - Зестафанского.In the swimming trunks of the first series, silico-manganese Zaporozhye Ferroalloy Plant, and the second series - Zestaphan.
Качество полученного металла полностью соответствует требовани м ГОСТа, причем содержание фосфора и углерода значительно ниже реглзментированных.The quality of the obtained metal fully complies with the requirements of GOST, and the content of phosphorus and carbon is significantly lower than the regularized ones.
В таблице приведены сравнительные данные по технико-экономическим показател м предлагаемого и известного способов производства .The table shows the comparative data on the technical and economic indicators of the proposed and known production methods.
При выплавке малоуглеродистого ферромарганца данным способом можно использовать марганцевую (с 33% марганца) руду с почти вдвое большим сквозным извлечением марганца, чем достигнуто при использовании более богатого (с 48% марганца) концентрата при выплавке ср еды еуглер од истого ферромарганца .When smelting low-carbon ferromanganese using this method, manganese ore (with 33% manganese) ore with almost twice as large manganese extraction can be used than is achieved using richer (with 48% manganese) concentrate in smelting eater e ugler ferromanganese.
По предлагаемому опособу получают более качественный сплав (ферромарганец) из более бедных марганцевых руд с более высокими технико-экономическими показател ми в сравнении с существующей технологией производства .According to the proposed method, a higher quality alloy (ferromanganese) from poorer manganese ores with higher technical and economic indicators is obtained in comparison with the existing production technology.
Предмет изобретени Subject invention
Способ получени малоуглеродистого ферромарганца из высокоосновной марганцевой руды руднотермической плавкой с силикомарганцем и известью, отличающийс тем, что, с целью расширени сырьевой базы, повышени степени извлечени марганца и улучшени качества сплава, силикомарганец и известь в виде смеси ввод т в руду после ее расплавлени .The method for producing low-carbon ferromanganese from highly basic manganese ore is carried out by ore-thermal smelting with silicomanganese and lime, characterized in that, in order to expand the raw material base, increase the degree of manganese recovery and improve the quality of the alloy, silicomanganese and lime are introduced into the ore after the smelting as a mixture.
