6 November, news came from the Panzhihua Vanadium steel plant, the plant this year, successfully developed a new application in the production of hot metal desulfurization agent to obtain the desulfurization efficiency, cost reduction and desulfurization desulfurization to reduce iron loss, "kill three birds" apparent effect. It is understood that, according to market demand, steel plant has gradually increased the proportion of low-sulfur steel. The steel mill with hot metal sulfur high into the plants, low temperature and poor flow characteristics of hot metal desulfurization, desulfurization costs, and desulfurization of iron loss and the demand for low sulfur steel production there is a big gap. To achieve low-cost, mass production of low sulfur steel, and product structure adjustment and the allocation of resources to maximize efficiency and a steelworks in November last year set up a "hot metal desulfurization mode full optimization of desulfurization technology" project group, the new desulfurization agent research and development as a priority project team. Plant engineering and technical personnel to cooperate actively with the relevant units, to take the "typical test - to expand testing - promote the use of" step by step mode to go through several rounds of testing, adjustment, summarize, determine the composition of the new sorbent composition, spray wind speed and operating standards. Production data showed that the desulfurization agent can make use of new desulfurization increased by 3% tons of iron desulfurization costs fell 3.07 yuan, desulfurization 0.131 percentage point reduction of iron loss. Since the second quarter of this year, with the mass production of the new sorbent used for desulfurization of hot metal indicators continue to optimization. 1 to 10 months, steel mills than the hot metal desulfurization, desulfurization pass rate, pass rate of sulfur into the converter, respectively 99.63%, 94.31%, 95.04%, were a record level.
