三明钢铁厂1号高炉由255m~3扩容到350m~3,1999年是投产后的第6个年头。上半年产铁190230t.比1998年同期多产铁22114t,增长13.15%,利用系数达到3.005t/m~3·d,入炉焦比449kg/t,同比降低35kg/t,节约焦炭6658t。铁水平均含Si0.54%,一级品率提高2.87%。吨铁喷煤87.36kg,吨铁矿耗1623.05kg(该炉没有加金属附加物),万吨铁悬料、塌料1.74次,位于三座高炉之首,见表1、表2。
Sanming Iron and Steel Plant No. 1 blast furnace from 255m ~ 3 capacity expansion to 350m ~ 3, 1999 is put into operation after the first 6 years. In the first half of the year, iron production was 190,230 tons, up by 22.15% over the same period of 1998, with an increase of 13.15%. The utilization factor reached 3.005t / m ~ 3 · d, into the furnace coke 449kg / t, down 35kg / t year on year, saving 6658t coke. Iron content is Si0.54%, a product rate increased 2.87%. Tons of iron PCI 87.36kg, tons of iron ore consumption of 1623.05kg (no additional metal added to the furnace), 10,000 tons of iron suspended material, collapse material 1.74 times, located in the first three blast furnace, see Table 1, Table 2.
