一、设备、工艺概况 现全国有四种类型的均热炉,共300多个 坑,分属15个初轧厂和一个厚板厂。 各类的均热坑数占总量的比例分别为:蓄 热复座式7.4％,中心烧咀式9.2％,四角烧咀 式27 .6％,单侧烧咀式55.8％。其中单侧烧咀 式已成为我国均热炉的主流。四角烧咀式系由 原中心烧咀式炉改造而成。 蓄热复座式炉1955年始建于鞍钢一初轧 厂,空、煤气予热温度高,燃耗低。第一批中 心烧咀式炉1956年在鞍钢二初轧厂建成投产, 设计为干出渣。1958年该厂在炉膛下部增设了 四个角部烧咀(喷射式,热负荷为总量的1/4, 并用焦粉助熔,实现了液体出渣。1962年又将
First, the equipment, process Overview Now the country has four types of soaking furnace, a total of more than 300 pit, belonging to 15 early rolling mill and a thick sheet plant. The proportions of all kinds of average heat pits in the total amount are 7.4% for heat storage multi-seat block, 9.2% for central Tsui block, 27.6% for quadripolar Tsui block and 55.8% for single-sided Tsui block. One-sided Tsui Tsui has become the mainstream of China’s soaking furnace. Corner Tsui Tsui Tsui-type furnace from the original heart-shaped furnace transformed from. Regenerative regenerative furnace was first built in 1955 in Anshan Iron and Steel Company a first rolling mill, air and gas preheating temperature is high, low fuel consumption. The first batch of Tsui Tsui furnace was completed and put into operation in Anshan Iron and Steel Company two early rolling mill in 1956, designed to dry slag. In 1958 the factory in the lower part of the furnace additional four corner burners (jet, heat load for the total 1/4, and coke powder to help achieve a liquid slag .1962 again
