高压炉顶操作是近代高炉先进技术操作经验之一,虽然高压操作的理论已于1915年由苏联科学家П.М.叶斯马斯克提出,而苏联开始采用高压操作是在1940年于比得罗夫斯克工厂,近年来高压操作在国外已经得到了广泛的采用。根据苏联的操作经验炉顶压力增高至0.5—0.7大气压时,可增产2—5％(个别工厂达到8—9％),焦比降低2—4％,炉顶瓦斯灰量减少30—50％。此外高压操作还可以降低生铁中矽与硫的含量 Although the theory of high-pressure operation was proposed by the Soviet scientist П.М. Yeys Musk in 1915, and the Soviet Union began to adopt high-pressure operation was in 1940 in the Bidro Vfks factory, in recent years high-pressure operation in foreign countries has been widely adopted. According to the operation experience of the Soviet Union, when the pressure in the top of the furnace is increased to 0.5-0.7 atm, it can increase 2-5% (8-9% in individual factories), 2-4% reduction in coke ratio and 30-50% . In addition, high-pressure operation can also reduce the content of silicon and sulfur in pig iron
