摘要
岩棉和矿渣棉并存、冲天炉熔制和电熔炉熔制并存、冷态渣和热态渣制棉并存、国内外生产线并存、岩矿棉产品种类齐全是我国岩矿棉工业的5个特点.冲天炉制备岩矿棉的单位产品可比综合能耗和可比熔融焦耗已基本实现《岩棉、矿渣棉及其制品单位产品能源消耗限额》(GB30183—2013)先进值目标,正在向单炉5 t级更大规模和更高节能发展.其中,焦炭炉熔制转变为电熔炉熔制是未来发展趋势.利用热熔渣制造岩矿棉制品可实现熔制的节能减碳和原料减碳的双重效应,产业发展方兴未艾.
The coexistence of rock wool and slag wool products,the symbiosis of cupola melting and electric melting process,the application of both the cold slags and hot slags as raw materials,the competition among the rock/slag wools(R/S wools)produced from exotic and domestic production lines and capability of producing all kinds of R/S wools are the five main characters of the manufacturing methods and commercial market of R/S wools in China.The comparable comprehensive consumption per unit product and comparable molten coke consumption for the preparation of R/S wools by cupola have basically reached the advanced value according to GB30183—2013.It is developing towards a larger scale and higher energy saving of 5 tons per furnace.Given the low carbon development concerns,the traditional coke furnace melting process will be gradually replaced by a more environmentally friendly electric melting process in the industry of R/S wools.Moreover,the utilization of hot slags as the raw materials not only realizes the recycle of solid wastes,but also reduces the carbon emission during the melting process,resulting in good comprehensive environmental protection,which will benefit on energy conservation.
