Description

TECHNICAL FIELD

[0001] The utility model relates to hot galvanizing steel sheet field especially a kind of cooling device of hot galvanizing steel sheet. BACKGROUND

[0002] Hot galvanizing sheet is mainly used in construction, household appliance, automobile, machinery, electronics, light industry and other industries, and most of hot galvanizing sheet needs to be formed by stamping in the use process of household appliance, automobile manufacturing and other users, and the shape of the hot galvanizing sheet is mostly rectangular. Due to the friction between the die and the hot galvanizing sheet, the coating is prone to powder loss and blackening during forming. Therefore, the present hot galvanizing self-lubricating steel sheet is different from the hot galvanizing sheet in that a layer of self-lubricating passivation solution is coated on the surface of the hot galvanizing self-lubricating steel sheet. After the passivation solution is dried and solidified, the coating contains a specific lubricant, so as to reduce the friction between the die and the steel sheet during forming of the hot galvanizing sheet, and to prevent the coating from powder loss and blackening.

[0003] In the preparation process of hot galvanizing steel sheet, the steel sheet needs to be treated by zinc pot first. After the steel sheet is taken out of the zinc pot, it has high temperature itself, and the thermal diffusion between iron and zinc still continues, which affects the toughness of the zinc coating. At this time, the steel sheet needs to be cooled and the temperature needs to be lowered to below 300°C in time. The existing cooling methods are mainly air cooling or water cooling. If air cooling is used, the air cooling speed is slow, which not only affects the production efficiency, but also affects the toughness of the coating. If water cooling is used, although the cooling rate can be improved, the steam generated during water cooling is prone to condensation of water droplets, which causes the steel sheet to hang water droplets, resulting in adsorption of dust and dirt on the steel sheet. Therefore, the present application provides a cooling device for hot galvanizing steel sheet to solve the above problems. UTILITY MODEL CONTENTS
