中温箱式电阻炉一般作为碳钢、合金钢另件在空气中正火、退火、淬火等热处理工艺的加热设备,也作其他加热用途。其加热温度950℃,在机械工艺等部门广泛使用,是当前用得最多的电炉炉种之一。我国目前生产的箱式电阻炉,仍以五十年代仿制产品为基础作了一些改进,但与当前国外同类型产品相比较技术经济指标低,普遍存在有升温时间长,空炉损耗功率大、炉温均匀性差、生产率低、结构笨重、庞大、机械化程度低等问题。在当前我国“四化”新长征中,显然这种炉子是不适应要求的。设计和制造性能好、效率高、省电、技术经济指标高的炉子,已成为电炉设计、研究、制造工作的迫切任务。特别是当前我国各行各业都在发展,电能很紧张,国家已十分重视能源节
Medium temperature box resistance furnace as a general carbon steel, alloy steel pieces in the air normalizing, annealing, quenching and other heat treatment equipment heating equipment, but also for other heating purposes. The heating temperature of 950 ℃, widely used in machinery and other departments, is currently one of the most used furnace furnace. China’s current production of box-type resistance furnace, still based on the fifties imitation products made some improvements, but compared with the current foreign products of the same type of technical and economic indicators are low, the prevalence of heating time is long, empty furnace loss power, Poor uniformity of furnace temperature, low productivity, bulky structure, large size and low degree of mechanization. In the current “four modernizations” of the new long march in our country, it is obvious that this kind of stove does not meet the requirements. Design and manufacture of high performance, high efficiency, energy saving, high technical and economic indicators of the furnace, electric furnace has become the design, research, manufacturing an urgent task. In particular, all walks of life in our country are developing, electricity is very tense, the state has attached great importance to Energy Section
