摘要
随着计算机与传感技术的进步,利用传感器测量电极长度并使用计算机代替人工控制,已成为矿热炉电极智能测量的新发展趋势。在矿热炉的正常工作过程中,存在热传导现象。基于拉普拉斯热传导方程,对工作中的石墨电极建立简易数学模型,利用多个温度点的温度差值及对应坐标,可以确定电极热端面位置和电极的长度。与传统的人工测量法相比,基于热力学的电极长度测量方法更加准确可靠,同时也避免了对工作人员造成伤害和不必要的资源消耗。
With the advancement of computer and sensing technology,sensors are used to measure electrode length and manual control is replaced with computers.This has become a new development trend for intelligent measurement of electrodes in submerged arc furnace.During the normal operation of a submerged arc furnace,there is a phenomenon of heat conduction.Based on the Laplace heat conduction equation,a simple mathematical model is established for the graphite electrode in operation.By using the temperature differences and corresponding coordinates of multiple temperature points,the position of the electrode's hot end face and the length of the electrode can be determined.Compared with traditional manual measurement methods,the electrode length measurement method based on thermodynamics is more accurate and reliable,while also avoiding harm to workers and unnecessary resource consumption.
