碳化硅高温涂料已在日本得到广泛应用,这种涂料用于各类热处理炉上节能效果最大。日本川崎制铁所知多工场一台退火炉,炉墙向火面涂刷碳化硅后,加热工件所需的时间缩短了四小时,炉子热效率提高约10%。日本的炼油加热炉应用这一技术,也取得了一定效果,据“日本热放射材研究所”的不完全统计,仅1980年日本就有15个炼油厂在39台炼油加热炉上使用了这种涂料,这些炉子有常压炉、减压炉、加氢精制炉、脱硫炉、润滑油溶剂脱
Silicon carbide high temperature coating has been widely used in Japan, this coating for all types of heat treatment furnace, the most energy-saving effect. Japan’s Kawasaki Ironworks know more workshops an annealing furnace, the furnace wall to the fire surface coated with silicon carbide, heating the workpiece to reduce the time required for four hours, the furnace thermal efficiency increased by about 10%. Japan’s oil refining furnace application of this technology has also achieved some results, according to “Japan Institute of Radiological Materials,” the incomplete statistics, only Japan in 1980, 15 refineries in 39 refineries used this Kinds of coatings, these furnaces atmospheric furnace, vacuum furnace, hydrofinishing furnace, desulfurization furnace, lubricant solvent off
