虽然用电炉正火控温准确,自动化程度高,少污染,便于操作。但是,我国目前大部分地区供电紧张,一次性投资较大,维修也比较复杂,因而正火成本高,致使电炉的使用受到一些限制。所以油炉显示了一定的优越性。但是油炉的弊端在于,控温难度大,污染严重,操作复杂。为此,我们在2.7t连续正火油炉上采用了XMTE-DKZ自控系统来进行温度控制。该炉膛长7m,6个喷嘴相对分布在两
Although the electric furnace normalizing temperature control accuracy, high degree of automation, less pollution, easy to operate. However, in most areas of our country, the power supply is tight, the one-off investment is relatively large, and the maintenance is also complicated. As a result, the cost of normalizing is high, which limits the use of the electric furnace. Therefore, the oil furnace shows a certain degree of superiority. However, the disadvantages of the oil furnace lie in the difficulty of temperature control, serious pollution and complicated operation. For this reason, we have adopted the XMTE-DKZ automatic control system for temperature control on a 2.7t continuous normalized oil furnace. The furnace length 7m, 6 nozzles are relatively distributed in two
