Description
Известен способ контрол выплавки стал в мартенозской печи, включающий контроль скорости обезуглероживани по расходу кислорода на окисление примесей металлической ванньи Недостатком способа вл етс сравнительно мала точность определени количества кислорода, израсходованного на окисление примесей ванны, св занна с большими погрешност ми в определении объема продуктов горенн потерь кислоро- да с продуктами горени .A known method for controlling smelting has become in a martenoz furnace, including controlling the decarburization rate of oxygen consumption for oxidizing metal bath impurities. The disadvantage of this method is the comparatively low accuracy of determining the amount of oxygen consumed for oxidizing bath impurities, which is associated with large errors in determining the volume of horn loss products. oxygen with combustion products.
Предложенный способ контрол более прост и точен, так как не требует определени объема продуктов горени и потерь кислорода с продуктами горени .The proposed control method is simpler and more accurate since it does not require determination of the volume of combustion products and the loss of oxygen with the combustion products.
Способ заключаетс в том, что в процессе плавки поддерживают посто нным критерий качества горе1 и (по содержанию и СО в продуктах горени , экстремальной температуре и т.п.), автоматически компенсиру отклонени от заданного критери изменением расхода кислородоносителей или топлива. Благодар посто нству критери качества прени можно при известном расходе топлива точно определить количество The method consists in the fact that during the smelting process the criterion of the quality of grief1 and (in terms of content and CO in combustion products, extreme temperatures, etc.) is maintained, automatically compensating for deviations from the predetermined criterion by changing the consumption of oxygen-carrying or fuel. Due to the consistency of the quality criterion, it is possible to accurately determine the quantity at a known fuel consumption.
кислорода, идушего как на сжигание топлива так и на окисление примесей ванны.oxygen, as well as the combustion of fuel and the oxidation of impurities bath.
Скорость обезуглероживани и содержани углерода в металле по расходу кислорода на окисление примесей ванны определ ют по уравнению (решаемому автоматическим вычислительным устройством), учитывающему расход кислорода; как на окисление углерода , так и на окисление кремни , маргаца , фосфора и железа. Уравнение учитывает также, что источникомокислени ; примесе вл ютс кислород атмосферы печи и кислород завалки (руды, окалины, ржавчииы скрапа).The decarburization rate and the carbon content in the metal according to the oxygen consumption for the oxidation of bath impurities are determined by the equation (solved by an automatic computing device), taking into account the oxygen consumption; both on the oxidation of carbon and on the oxidation of silicon, manganese, phosphorus and iron. The equation also takes into account that the source of oxidation; The impurities are the oxygen of the furnace atmosphere and the oxygen of the charge (ore, scale, rust scrap).

б)до момента полного использовани кислорода завалки углерод ванны окисл етс до СО за счет ислорода завалки, а палее - за счет кислорода атмосферы печи .b) until the complete use of oxygen of the filling, the carbon of the bath is oxidized to CO due to the oxygen of the filling, and later, due to the oxygen of the atmosphere of the furnace.
