Abstract

The invention relates to the technical field of strip steel machining, and especially relates to a control device for a pot-entering temperature of strip steel in a hot-galvanizing annealing furnace. The control device for the pot-entering temperature of the strip steel in the hot-galvanizing annealing furnace comprises a support, wherein a conveying mechanism used for conveying the strip steel, an air blowing mechanism used for blowing air to the strip steel, a heating mechanism used for heating the strip steel, a power supply mechanism used for supplying power and an electricity conducting mechanism used for conducting electricity are arranged on the support; the electricity conducting mechanism comprises a rotating rod rotationally connected to the support through a horizontal shaft, one end of the rotating rod is placed on the upper surface of the strip steel, and an electricity conducting head is arranged at the other end of the rotating rod and connected to the power supply mechanism through a conducting wire; a first receiving head which is abutted against the electricity conducting head when the electricity conducting head overturns downwards is arranged on the air blowing mechanism; and a second receiving head which is abutted against electricity conducting head when the electricity conducting head overturns upwards is arranged on the heating mechanism. According to the invention, the galvanizing quality of the strip steel can be improved.

Description

technical field [0001] The present application relates to the technical field of strip steel processing, and in particular to a temperature control device for strip steel entering a pot of a hot-dip galvanizing annealing furnace. Background technique [0002] As the key parameter of the hot-dip galvanizing process, the temperature of the strip steel entering the pot is directly related to the adhesion of the coating. An appropriate temperature for entering the pot can ensure that the strip steel enters the pot to form an intermediate adhesion layer. The temperature of the strip steel entering the pot is directly related to the surface defects of the strip steel such as zinc grains and zinc flow lines, as well as the production of zinc dust and zinc slag. [0003] When the heated strip steel is transported into the zinc pot, if the strip steel is thick gauge, the temperature of the zinc liquid in the zinc pot will rise; if the strip steel is thin gauge, the zinc liquid temper...
