摘要/Abstract

摘要： 钢包是连接炼钢与浇注环节的容器，即将承接炼钢炉的注入钢水的钢包容器内壁温度直接决定了炼钢炉的出钢温度，与企业节能降耗密切相关.钢包在装盛钢水前的热修工位由行车吊装放置，其放置后的绝对位置难以固定，从而导致温场分布无法确定.针对此现状，本文提出了一种激光定位与扫描的钢包温度场测量方法，先利用定位激光确定被测钢包所处的空间坐标，再由主测量平台执行机构带动扫描激光与红外测温传感器扫描钢包内壁面获取钢包内壁各被测点的测距与温度值，根据空间坐标关系，将被测点测距值映射为钢包坐标数值，从而得到钢包内壁各点坐标与温度值，即温场分布.现场实验表明：该方法可实现钢包温场的获取，坐标定位不确定度≤ 3.0mm；温度测量最大误差4.7℃，最小误差0.5℃，平均误差小于3.3℃，达到较高定位与测量精度，为基于温度信息的冶金工艺控制提供重要参数信息.

Abstract: Ladle is a container which used to connect the steel-making and pouring sections.The tapping temperature of the steel-making furnace is directly determined by the temperature of the inner wall of the ladle,which is closely related to the energy saving and consumption Reduction of the enterprise.Before the ladle is filled with molten steel,the ladle is placed in the hot repair station by driving.The absolute position of the ladle after placement is difficult to fix,resulting in a temperature field distribution that cannot be determined.So,this article presents a method for measuring the temperature field of ladle by laser positioning and scanning.Firstly,the positioning laser is used to determine the spatial coordinates of the ladle.Then,the actuator of the main measurement platform drives the scanning laser and the infrared temperature measurement sensor to scan the inner wall surface of the ladle to obtain the distance measurement and temperature of each measured point on the inner wall of the ladle.According to the spatial coordinate relationship,the distance measurement values of the measured are mapped to the ladle coordinate values,therefore we obtained the coordinates and temperature values of the inner wall of the ladle.So the temperature field distribution is obtained.The field experiment shows that the method can obtain the temperature field of the ladle,the coordinate positioning uncertainty is no more than 3.0mm;the maximum error of temperature measurement is 4.7℃,the minimum error is 0.5℃,and the average error is less than 3.3℃.The method achieves to high positioning and measurement accuracy,it will provide important information for steel-making control based on temperature information.

Key words: infrared temperature measurement, ladle, inner wall temperature, laser positioning, scanning
