对于带式烧结机而言,机尾三个风箱的废气温度测量值通常作为烧结终点判断的主要依据。因此,要求测量值能真实而又迅速地反映废气温度。 以往,烧结风箱废气测温热电偶安装在风箱弯管的下部(A)处,见图1。由于台车两边弹性滑道,尤其是最后一个风箱靠机尾一侧漏入了周围的冷空气,致使热电偶的测量值比废气实际温度低,漏风越严重相差也越大。其测量结果失去了作为烧结终点判断依据的价值。例如,在生产过程中人们已
For the belt sintering machine, the measured values of the exhaust temperature of the three wind boxes at the tail end are usually the main basis for judging the sintering end point. Therefore, it is required that the measured values reflect the exhaust gas temperature accurately and promptly. In the past, sintering bellows exhaust temperature thermocouple installed in the lower part of the bellows (A), shown in Figure 1. As the trolley elastic slides on both sides of the trolley, especially the last bellows leaking into the cold air around the tail end, the measured value of the thermocouple is lower than the actual temperature of the exhaust gas, and the more serious the air leakage is, the larger the difference is. The measurement lost the value as the basis for determining the sintering end point. For example, people in the production process already
