在大型高炉所属的内燃二通式热风炉上,由于各部分结构所处位置和遭受破损因素的不同,其相对寿命也相差很多。例如炉底板、下部的炉墙砌体和炉壳,其损坏的速度和程度一般要比中、上部的快,而且严重的多,突出地在燃烧室墙、热风出口和上部格子砖等部位。针对这种不均衡的损坏情况,应选择合理的检修方案。本文着重介绍
In the internal-combustion type general-purpose hot blast stove to which the large-scale blast furnace belongs, the relative life span varies greatly due to the location and damage factors of each part structure. For example, the furnace floor, the lower furnace wall masonry and furnace shell, the damage speed and degree is generally faster than the middle, the upper part, and more serious, prominent in the combustion chamber wall, hot air outlet and the upper lattice brick and other parts. For such unbalanced damage, a reasonable repair program should be selected. This article focuses on
