Description

Способы, примен емые дл  получени  передельных шлаков из марганцевой руды, св заны с высоким расходом электроэнергии и производственными затратами.The methods used to obtain pig slag from manganese ore are associated with high energy consumption and production costs.

Описываемый способ получени  передельных шлаков из марганцевой руды, используемых при производстве металлического марганца, ферромарганца и силккомарганца, позвол ет снизить энергетические затраты и производственные расходы и обеспечивает получение бесфосфористых передельных шлаков высокого качества даже при использовании в качестве исходного сырь  низкосортных марганцевых концентратов . Достигаетс  это тем, что процесс получени  передельных шлаков осуществл ют в две стадии: путем окислительной плавки исходной руды и последуюшей дефосфораиии расплава в восстановительной атмосфере при избытке углерода.The described method for producing pig slags from manganese ore used in the production of manganese metal, ferromanganese and silk manganese reduces energy costs and production costs and ensures production of high quality phosphorus free slags even when low-grade manganese concentrates are used as feedstock. This is achieved by the fact that the process of obtaining waste slag is carried out in two stages: by oxidizing smelting of the initial ore and subsequent dephosphorization of the melt in a reducing atmosphere with an excess of carbon.

Устройство дл  осуществлени  предлагаемого способа выполнено в виде циклонной печи дл  плавлени  руды и двух дуговых печей дл  дефосфорации расплава. Это устройство состоит (см. чертеж) из печи /, установленной на подвижной круговой опоре, обеспечивающей поворот на 180°, и двух восстановительных камер 2. представл ющих собой дуговые электропечи с электродами 3.The device for carrying out the proposed method is made in the form of a cyclone furnace for melting ore and two arc furnaces for dephosphorizing the melt. This device consists (see the drawing) of a furnace / mounted on a movable circular support that provides 180 ° rotation, and two reduction chambers 2. These are electric arc furnaces with electrodes 3.

Исходна  руда загружаетс  в циклонную печь посредством течек через бункер 4. Природный газ и подогретое, например, до 350-400 дутье подаютс  тангенциально к стенкам печи со скоростью пор дка 120 м1сек ц верхнюю часть печи через каналы или горелки 5. Отход щие газы вывод тс  рз циклонной печи по центральному каналу 6, после чего подвергаютс  очистке, а их тепло может быть использовано дл  подогрева дуть  в рекуператорах. Расплавленна  шихта перетекает из циклонной печи в одну из дуговых печей по каналу 7.The original ore is loaded into the cyclone furnace by leaking through the bunker 4. Natural gas and heated, for example, up to 350-400 blast are fed tangentially to the furnace walls at a speed of about 120 milliseconds and the upper part of the furnace through channels or burners 5. Exhaust gases are removed RZ of the cyclone furnace through the central channel 6, after which they are cleaned, and their heat can be used for heating and blowing in recuperators. The molten charge flows from the cyclone furnace to one of the arc furnaces through channel 7.

По заполнении первой дуговой электропечи подачу шихты, газа и дуть  в циклонную печь прекращают и последнюю поворачивают наBy filling the first electric arc furnace, the supply of the charge, gas and blowing into the cyclone furnace is stopped and the latter is turned on
