A few days ago, the five blast furnaces of Tisco iron & Steel Plant, which have been in operation for 13 years and 8 months, successfully completed the historic mission of the safe production of the first generation of furnace age. At the same time, the five blast furnaces also realized the recovery and utilization of 100% gas for the first time.
Tisco five blast furnaces were put into operation on October 13, 2006. Blast furnace operation nearly 14 years, 4996 days of safe production, production of molten iron 46.97 million tons, the unit furnace capacity output of 10,798 tons, for our company's production and operation made great achievements, blast furnace life in the same level of China's blast furnace at a higher level.
According to the usual practice, the blast furnace shutdown requires the release of residual gas for nearly 20 hours, which not only affects the environment, but also wastes secondary energy. This way of shutdown no longer meets the current environmental protection requirements. In order to meet the requirements of ultra-low emission, the realization of green boiler stop, taiyuan iron organization staff repeatedly research, reference, established the "top water recycling gas boiler stop line empty materials, the whole method", and is prepared through a series of operations, the successful completion of the gas recovery boiler stop completely, recycles all more than 500 cubic meters of gas, into the company network. Relevant personnel of this plant introduce, the whole process of empty material line, has reached the expected target of material drop line, safe, fast, smooth realization of green stop furnace.
This factory expresses, they will continue to do well the work that stop furnace overhaul, together with construction unit, decisive battle 120 days, complete overhaul task smoothly, let five blast furnace continue to make new contribution for company production and operation with brand-new look.
