S35C型板坯连续式热处理炉炉温均匀性测试与分析

利用自研的黑匣子炉温测试系统,依据AMS270E《高温测量》设计了大型连续式热处理炉内运动板坯的均匀性测试方案,并基于设计方案对某钢厂S35C型板坯连续式热处理炉进行实际均匀性测试与分析。测试结果表明,自研的黑匣子炉温测试系统能满足高温板坯连续运动条件下的温度均匀性测试要求。板坯入炉后温度迅速上升,并逐渐达到目标温度进入均热阶段,对比均热段数据,板坯各个位置温度都达到指标要求,整体温度均匀性较好,板坯在炉内的热处理温度和时间与规定的工艺设计要求一致。为大型连续炉均匀性和板坯测试提供一种有效的方法。

Test and Analysis on Temperature Uniformity of S35C Slab Continuous Heat Treatment Furnace

Based on AMS270E "high temperature measurement" , a test program for the uniformity of moving slab in a large continuous heat treatment furnace is designed by using the self-developed black box furnace temperature measurement system, the uniformity of S35c slab continuous heat treatment furnace in a steel plant was tested and analyzed based on the design. The test results show that the self-developed black box furnace temperature test system can meet the temperature uniformity test requirements of continuous motion of high-temperature Slab. The temperature of the slab increases rapidly after being fired, and gradually reaches the target temperature and enters the homogenization stage. Compared with the data of the homogenization stage, the temperature at each position of the slab reaches the target, and the overall temperature uniformity is good, the heat treatment temperature and time of slab in furnace are consistent with the requirement of process design. It provides an effective method for homogeneity and slab test of large-scale continuous furnace.
