摘　　要：为了获得精确的工段钢包内壁温度参数才能实现对炼钢质量的有效控制,并有效降低成本,设计了一种通过激光定位和扫描方式来实现测定钢包温度的方法,通过激光对钢包的空间坐标进行定位,再通过主测试平台控制结构对描钢包内壁面实施激光扫描并通过红外测温传感器进行扫描分析,结合空间坐标参数,通过三维映射方法把钢包内壁面上的测试点转化为钢包坐标,最后根据系统对应测试点温度生成钢包内壁温场数据。测试得到的温场变化曲线与钢包的温场特征基本相同,通过激光多点交叉方式达到的定位精度在2.8 mm以内;温度测试误差在3.2℃以内,在可控的范围之内,满足设计要求,为提高基于温度信息的冶金工艺控制起到一定的设计作用。In order to obtain accurate section of ladle lining temperature parameters to achieve the effective control of the quality of steel,and effectively reduce the cost,we design a laser positioning and scanning way to implement the ladle temperature measuring method,by fixing the space coordinates of the ladle,laser again through the master test platform control structure for tracing ladle inner surface laser scanning and scanning by an infrared measuring temperature sensor analysis,combined with the spatial coordinates parameters,through 3 d mapping method to test point on the surface of the ladle lining into ladle coordinates,according to the system corresponding to the test point temperature of ladle lining temperature field data.The temperature field variation curve obtained in this paper is basically the same as the temperature field characteristics of ladle,the positioning accuracy achieved by the laser multi-point crossing method is within 2.8 mm.The temperature test error is within 3.2℃,within the controllable range,and meets the design requirements.This study plays a certain role in improving the metallurgical process control based on temperature information.
