本文对高炉风口烧坏的原因进行了认真分析,认为引起风口大量烧坏的主要原因是配用了大量强度差、灰分高的土焦,造成炉缸焦灰堆积,边缘结厚,铁水在风口沉积。经过一段时间的反复改制和试验,研制成功了钢质马蹄形风口,解决了风口大量烧坏的问题。该种钢质马蹄形风口造价仅为铜风口的1/7,而寿命却提高了5倍,同时具有良好的经济效益。
In this paper, the reasons for the burned blast furnace outlet were carefully analyzed. It is considered that the main reason causing the large burnt out of the tuyere is that it is equipped with a large amount of soil coke with poor strength and high ash content, resulting in accumulation of burnt ash, thick edge knots, Deposition. After a period of repeated restructuring and testing, the successful development of the steel horseshoe-shaped outlet, to solve the problem of a large number of burners. The cost of this steel horseshoe-shaped outlet is only 1/7 of the copper tuyere, but the life expectancy has increased by 5 times, at the same time have good economic benefits.
