Series of thermocouple primarily measure temperature of blast furnace and blast heater iniron and steel industry . they have so many advantagesshown in anti high temperature , high accuracy , against corrosion , scouring - resistant and long in service etc T - wrr - 3系列热电偶适用于钢铁行业高炉热风炉的温度测量，具有耐高温精度高耐腐蚀抗冲刷使用寿命长等优点。
Ten years production practice of self - preheating hot air furnace system at ansteel were summarized and based on this technology , it was succeed that self - preheating hot air furnace system of no . 7bf was established , self - preheating hot air furnace technology gets development 摘要总结了10年来鞍钢热风炉自身预热系统的生产实践，并在此基础上建成了7 (上标# )高炉热风炉自身预热系统，使热风炉自身预热技术得以发展。
Abstract : by using the 3 - d unsteady state heat transfer equation , the heat convection and radiation between the checker and the gas which flows through the checker holes , and the heat conduction among the checker in the chamber of the hot blast stove were studied . the time dependable gas temperature and the temperature distributions within the checker were obtained 文摘:应用三维非稳态热量传输方程，对高炉热风炉在燃烧过程中蓄热室内格子砖与气体之间的对流和辐射传热，以及格子砖内部的导热过程进行了耦合求解.得到了在燃烧期内格子砖及燃烧过程中燃烧废气的温度分布情况及其随时间的变化规律
