Description
СПОСОБ ИНТЕНСИФИКАЦИИ ДОМЕННОЙ ПЛАВКИMETHOD FOR INTENSIFICATION OF A DOMAIN MELT
Известен способ интенсификации доменной плавки путем подачи в центр горна кислорода через водоохлаждаемую фурму.There is a method of intensification of the blast smelting by feeding oxygen to the center of the hearth through a water-cooled lance.
Однако положительные результаты этого способа были лишь при выплавке доменных ферросплавов, требующих высокой температуры в горне.However, the positive results of this method were only in the smelting of domain ferroalloys, requiring a high temperature in the furnace.
Предложенный способ отличаетс тем, что совместно с кислородом в центр горна вдувают природный газ, пал или другие вещества, которые в зоне горени химически превращаютс в восстановительные газы с поглощением тепла.The proposed method is characterized in that, together with oxygen, natural gas, palladium or other substances are blown into the center of the furnace, which in the combustion zone are chemically converted into reducing gases with heat absorption.
Расход дуть через центральную фурму устанавливают в таких, пределах, что количество газифицированного углерода кокса в центральной части горна было в отношении 0,5- 1,2 от количества углерода, газифицированного на воздушной фурме. Добавка природного газа или других веществ к кислороду в указанном отношении позвол ет регулировать температуру в центральной части горна и активизировать его работу.The flow rate to blow through the central tuyere is set in such limits that the amount of gasified coke carbon in the central part of the hearth was in the ratio of 0.5-1.2 of the amount of carbon gasified on the air tuyere. The addition of natural gas or other substances to oxygen in this ratio allows one to regulate the temperature in the central part of the hearth and activate its work.
Предмет изобретени Subject invention
Способ интенсификации доменной плавки, включающий подачу кислорода, пара и природного газа в центр горна доменной печи через водоохлаждаемую фурму, отличающийс тем, что, с целью регулировани температуры в центральной части горна, расход дуть через фурму поддерживают таким, чтобы количество газифицированного углерода кокса в центре горна было в отношении 0,5-1,2 от количества углерода кокса, газифицированного на одной периферийной воздушной фурме.A method for intensifying blast-furnace smelting, including the supply of oxygen, steam and natural gas to the center of the hearth of a blast furnace through a water-cooled tuyere, characterized in that, in order to control the temperature in the central part of the hearth, the flow through the tuyere is maintained so that the amount of carbonized coke carbon in the center the hearth was in the ratio of 0.5-1.2 of the amount of carbon of coke gasified on one peripheral air tuyere.
