Abstract
Спосіб промивки горна доменної печі включає подачу у фурми печі високонагрітого дуття з підвищеною концентрацією кисню і паливної добавки, подачу якої змінюють після відкриття чавунної льотки з періодичним повторенням цієї операції на всіх фурмах або по секторах. Як паливну добавку використовують пиловугільне паливо, витрату якого періодично знижують на 20-40 % від його поточної витрати через 10-15 хв після початку випуску чавуну на 25-35 хв.The method of washing a blast furnace includes the supply of a highly heated blast with an increased concentration of oxygen and a fuel additive to the lances of the furnace, the supply of which is changed after the opening of the cast-iron fly with periodic repetition of this operation on all lances or in sectors. As a fuel additive, pulverized coal fuel is used, the consumption of which is periodically reduced by 20-40% from its current consumption 10-15 minutes after the start of iron production for 25-35 minutes.
