According to China's national conditions, the introduction of Japan, Ltd. Kawai lime shaft kiln technology, in accordance with 'edge introduction, digestion and absorption edge, while the development of' the spirit we have designed energy-saving and environmental protection has become JHZS automation lime shaft kiln. And the formation of a number of Chinese patents. It has been widely at home and abroad to build up production nearly 100. In recent years, with its significant energy saving, environmental standards, high degree of automation, high product quality, low construction cost, built by the advantages of short cycle to favor state-owned large and medium, private and individual enterprises and many Southeast Asian countries. 1 lime knowledge, large central air-hybrid composite burner cooled by a heat-resistant steel frame and fire-resistant material made of high temperature, wear-resistant, long life, the burning power of 5 ~ 15GJ / h. Being fired band center and expansion of the center to provide a flame. Management of the lime kiln (kiln) central stream is not enough, the temperature distributed unevenly, raw burn center and edge over burning issues. Improve the TGS lime kiln (kiln) yield and quality, help lime kiln (kiln) is large. It can provide a solid high active lime (lime) steelmaking. 2, roof combustion air preheater, located in the roof above the material surface slow flow space, small green lime kiln, effectively avoid the wear and thermal expansion problems and the dust and gas of charge. When receiving the boiler combustion air pipe can be preheated to 220-300 ℃, greatly improving the lime kiln (kiln) thermal efficiency than usual blast furnace gas lime kiln (kiln) throttling gas more than a third. 3, Japan pit side burner, to special fire-resistant material replace the furnace heat of steel, burning solid and reliable, long life and easy tempering. Blast furnace maintenance and shutdown: continue for a long generation furnace served, its equipment, structure, lining be worn in production, some way in need of repair, environmental protection lime kiln manufacturers, some want off the wind, and some want to shutdown in order to carry out replacement, such work is called maintenance. Access by time and nature can be divided into four categories: temporary maintenance, preventive maintenance, repair and overhaul. A temporary repair and regular maintenance overhaul mainly refers to temporary change vents and small slag tap, also including small repair work must address. Temporary access to off the wind, the wind off the program on short-term operations. To replace the air when regular maintenance or in large sets of sets, green lime kilns, blast pipe, part of the furnace body cooler, skip, hot air valve, distributor and so on. Periodic maintenance time is short, there are more than ten hours, up to several days long, so long off the air by the blast furnace process. Second, in the repair and overhaul of heavy repair work, the cost of environmental protection lime kiln, when during a routine overhaul can not handle, blast furnace should be in repair. In the repair projects are: repair, relining, replace the upper cooler, replace distributor, hoist rope wheel. In the generation furnace process, repair once or twice normal. The repair time required for five days to a month, with the workload varies. The repair of the blast furnace to be shutdown, but hold residual iron. Are hearth furnace charge to hold in addition, depending on whether the replacement hearth brick lining and cooler. Overhaul including the replacement of all lining (especially the bottom), the replacement of one or all of the metal structure, expanding blast volume and the like. Overhaul time to be 30 to 45 days, medium-sized blast furnace is 25 to 40 days.
