倒焰窑炉烧成所用的闸板,目前各企业最通用的是钢板或耐火板。而钢板和耐火板都有不同的缺点:钢板主要是在高温时氧化很快,使用寿命很低,几乎每烧一窑就需要一块或几块;采用大型耐火板来做闸板,在使用时感到非常笨重和有炸裂现象,并且生产这种大型耐火板亦很困难。重庆第三钢铁厂首先在耐火材料车间推行了用水冷却闸板,根据目前情况,烧粘土砖已使用2年左右,尚未完全损坏。现将水冷却闸板用简图介绍于下:
Flame firing furnace used in the gate, the most common enterprise is currently steel or refractory board. The steel and refractory board has different shortcomings: steel is mainly in high temperature oxidation fast, low life expectancy, almost every kiln will need one or a few pieces; the use of large fire-resistant board to do the gate when in use Feel very bulky and bursting, and it is also difficult to produce such a large refractory board. Chongqing Iron and Steel Plant, the first in the refractory materials workshop to promote the use of water cooling sluice, according to the current situation, burned clay brick has been used for about 2 years, not yet completely damaged. Now the water cooling shutter with a simple introduction below:
