板坯加热炉装设废气喷射预热设备的目的是为了降低能耗、增进生产率。本文阐述了这种对降低能耗具有特殊参考价值的设备的利用.用废气喷射获得的传热系数,以高速把加热炉生产的废气喷在装入的板坯上,使其板坯充分预热为目的。采用新的预热设备要比采用普通加热炉对废气热得到的利用大得多。川崎重工业公司针对这个问题,用一座工业生产炉研究了气体喷射传热.这种喷射预热设备已应用在日本钢铁公司大分厂(Oita works,Nippon SteelCorp.)新型中厚板轧机1号加热炉上。这种加热炉自从1977年1月投产以来,没有发生任何设备故障,并且降低了能耗.
Slab furnace exhaust gas injection preheating equipment designed to reduce energy consumption and increase productivity. This paper describes the use of such equipment that has a special reference value for reducing energy consumption by using the heat transfer coefficient obtained by the injection of the exhaust gas to spray the exhaust gas produced by the furnace at a high speed onto the slab charged so that the slab is sufficiently pre- For the purpose of heat The use of new preheating equipment is much greater than the use of an ordinary reheating furnace for exhaust gas heat utilization. In response to this problem, Kawasaki Heavy Industries Co., Ltd. investigated gas-jet heat transfer with an industrial furnace, which has been used in No. 1 heating furnaces of Nippon Steel Corp.’s new plate mill at Japanese steelmaker Oita Works (Nippon Steel Corp.) on. Since this furnace was put into operation in January 1977, there have been no equipment failures and energy consumption has been reduced.
