我们厂铸造车间使用的是 2t/h多排小风口冲天炉。长期以来,在冲天炉熔炼过程中,人们对底焦高度的控制,都是通过间接的途径或凭经验进行粗略地估计、判断,因而难以掌握熔炼中底焦的真实高度。为了很好地解决这个问题,提高经济效益,经过分析、试验,我们设计制作了冲天炉底焦高度观察装置,其结构如图所示。经近一年来使用,情况一直正 Our factory foundry workshop is 2t / h multi-row small outlet cupola. For a long time, in the process of cupola melting, the control of the bottom coke height is roughly estimated or judged by indirect means or by experience, so it is difficult to grasp the true height of the melting midsole. In order to solve this problem well and improve the economic efficiency, we have designed and manufactured the observation device of the bottom-of-the-oven focal depth by analyzing and testing. Its structure is as shown in the figure. After nearly a year of use, the situation has been positive
