摘要
随着市场对热镀锌产品表面质量要求日益提高,锌锅热平衡的应用也得到了深入,利用两种锌锅热平衡计算方法来确定带钢入锌锅温度,有助于监控锌锅的工作状态。一种方法主要是利用传热学理论公式来计算出锌锅热损失消耗的热量,另一种方法是在锌锅处于备用状态时直接从感应加热器感应线圈电表中的读数得出锌锅的热损失消耗的热量。两种热平衡计算方法都精确地计算了带钢入锌锅温度,完全可以用来验证炉鼻子处板温仪测量结果的正确性。
With the increasingly demand for the galvanized product surface quality by the market,the application of zinc pot heat balance has been deepened.It is helpful to monitor the zinc pot＇s working condition using two kinds of calculation methods of heat balance to confirm strip entry temperature.One method is to work out zinc pot heat losses by the formula of heat transfer theory,and the other is to get the losses directly from the reading of the ammeter（heater＇s induction coil） when the zinc pot is placed into the standby mode.Both the methods can work out strip＇s entry temperature precisely and can be used to verify the correctness of the pyrometer at the furnace nose.
