ZBF-T100 Blast Furnace High-presion Water Temperature Difference Monitor System Introduction

 

高炉软水密闭循环系统冷却壁水温差测量是高炉自动化与测控的关键技术。随着高炉控制技术的发展和工艺要求的提高，高炉冷却水温差测量和控制就显得更为重要。在实际生产中，冷却水温差过大反映了炉壁温度过高，严重影响高炉寿命，加大冷却水量就可以使温差变小，但温差过小则造成能源浪费，增加生产成本。准确稳定的测量温差是控制的基础，对于高炉热负荷的计算，冷却水温差是一个重要的参考数据。从现代炼铁工艺要求看，准确稳定的水温差测量对指导高炉炉型的维护至关重要。

The water temperature difference measuring for closed loop soft water cooling system of blast furnace is key technology for automation and measuring & controlling of blast furnace. With development of blast furnace controlling technology and higher requirement of production, the high-precision measuring and controlling of blast furnace cooling water is more and more important. In production procedure, higher temperature difference of cooling water implies over-heat of furnace wall, and will effect the lifetime of blast furnace; On the contrary, lower temperature difference means over-cooling, will lead to waste of energy and increase cost. As for calculation of blast furnace heat load, the cooling water temperature difference is the key parameter, and also means great value for maintenance of furnace.

The ZBF-T100 system can calculate heat load by instantly, continuously measuring the temperature difference of input-output cooling pipes and instantaneous flow rate. By these data the operator can figure out the temperature changing and heat distribution, hence insures the normal activity and prolongs the lifetime of blast furnace.
