一、概述在冷轧带钢的生产过程中,采用罩式炉对带钢卷材进行退火处理是目前冷轧带材的主要热处理方法。我厂带钢分厂冷轧车间是个年产3000～3300吨弹簧、滚珠、不锈等钢种的冷轧带材专业部门,大型电加热钟罩式炉是该车间的主要热处理生产设备之一。该车间现拥有罩式炉10座(套):其中炉台10座;炉罩6座;总装机容量为1680千瓦;年产品耗电量为390～40&万千瓦小时,占该车间全年生产总耗电量的53～54％。根据我厂所进行的电能平衡测试工作结果表明,大型钟罩式炉的电能利用率一般为25～33％;其单耗约在1.34～1.62×10~6千焦/吨(带材),这与上海市计划用电办公室所制定的电加热炉窑电能利用率应达到≥40％的指标相距很大。为此,针对生产中罩式炉耗电大,炉衬
First, an overview In the cold-rolled strip production process, the use of hood furnace strip annealing for the current strip is the main heat treatment method. Cold-rolled steel plant in our factory is an annual output of 3,000 to 3,300 tons of spring, ball, stainless steel and other types of cold-rolled strip professional departments, large-scale electric heating bell furnace is the workshop one of the main heat treatment equipment . The workshop now has a hood stove 10 (sets): of which 10 stoves; stove cover 6; total installed capacity of 1680 kilowatts; annual product power consumption of 390 ~ 40 & million kilowatts hours, accounting for the workshop annual total production 53 ~ 54% of power consumption. According to the results of the power balance test conducted by our factory, the energy utilization rate of large bell-type furnaces is generally 25-33%, and the unit consumption is about 1.34-1.62x10-6 kJ / ton (strip) This is in line with the planned electricity office in Shanghai electric heating kiln power utilization should reach ≥ 40% of the indicators are far apart. To this end, for the production of hood furnace power consumption, lining
