Изобретение относитс к области черной металлургии, в частности, в способам отоплени мартеновсних печей при выплавив стали.The invention relates to the field of ferrous metallurgy, in particular, to methods for heating open-hearth furnaces in steel production.
Известен способ отоплени мартеновских печей, включающий подачу в рабочее пространство под углом к поверхности ванны подогретого воздуха и топлива, часть которого ввод т в печь в реформированном виде.There is a known method of heating open-hearth furnaces, which includes supplying heated air and fuel to the working space at an angle to the bath surface, part of which is introduced into the furnace in a reformed form.
В известном способе реформированное топливо при входе в рабочее пространство смешиваетс с частью нереформированного топлива. Однако в периоды завалки и прогрева, характеризующиес интенсивным теплопоглощением, при подаче реформированного топлива в общий его потов неэффентивно используетс тепло.In the prior art, the reformed fuel is mixed with a portion of the unreformed fuel upon entering the working space. However, during the periods of filling and warming up, which are characterized by intense heat absorption, when the reformed fuel is fed into its total sweat, heat is ineffectively used.
По предложенному способу дл повышени эффективности использовани оплива в периоды завалки и прогрева скрапа нереформированное топливо ввод т в печь под углом на 2-5° меньшим, чем угол наклона потока реформированной части топлива к поверхности ванны.According to the proposed method, in order to increase the efficiency of use of fuel during periods of filling and heating of scrap, unreformed fuel is introduced into the furnace at an angle of 2-5 ° less than the angle of inclination of the flow of the reformed part of the fuel to the bath surface.
Б мартеновскую печь через ее головки подаютс подогретый в регенераторах воздух и природный газ, который направл ют под углом н ванне.The open-hearth furnace through its heads is supplied with air heated in regenerators and natural gas, which is directed at an angle n to the bath.
Часть природного газа предварительно подвергают термической обработке в реформаторе , при этом нереформированный природный газ подаетс отдельно от реформированной части топлива потоком с углом наклона меньшим, например, на 3°, чем угол наклона реформированного потока топлива.A portion of natural gas is pre-heat treated in a reformer, while unreformed natural gas is supplied separately from the reformed part of the fuel with a slope less than, for example, 3 ° than the inclination angle of the reformed fuel flow.
Благодар такой подаче реформированного гошшва, имеющего в резульг тате термоподготовви температуру более 900°С и сгорающего с выоойой температурой; и нереформированной части достигаетс эффективное использование тепла. Б период после заливки чугуна реформированное топливо целесообразно .вводить в поток нереформированной его Due to such a supply, reformed couchesha, which as a result of thermal preparation, has a temperature of more than 900 ° С and burns with high temperature; and the unreformed part achieves efficient use of heat. After a period of cast iron casting, it is advisable to introduce reformed fuel into its unreformed flow.
