6.节能措施日本热处理炉制造商在炉子设计方面采取了一系列节能措施,而节能技术在日本得到了迅速地发展。除了前述在炉墙结构上广泛采用重量轻、热容量小、导热系数低的陶瓷耐火纤维是节能的一条重要途径外,近年来在连续炉及万能炉的炉体从方形截面改为园形截面已成为一种趋势,据介绍这样可减少散热面14%,减少了散热量,搞好了可节能5～7%的效果。其次在废热利用技术上发展也很快,例如渗碳炉内排出的大量可燃废气,每立方米含热量约1400大卡,而东热就将此废气作为工件渗碳前净化及预热的脱
6. Energy-saving measures Japanese heat treatment furnace manufacturers have adopted a series of energy-saving measures in furnace design, and energy-saving technologies have been rapidly developed in Japan. In addition to the aforementioned widely used in the furnace wall structure of light weight, small heat capacity, low thermal conductivity ceramic refractory fiber is an important way to save energy, in recent years in continuous furnace and furnace furnace body from the square section to a circular cross section has been As a trend, it is reported that this can reduce the heat 14%, reducing the heat, improve the energy saving of 5 to 7% of the results. Second, rapid development in the utilization of waste heat technology, such as a large number of combustible waste gas discharged from the carburizing furnace, calorifics per cubic meter of about 1400 kcal, while the east heat will be the workpiece as the carburizing purification and preheating off
