Abstract

The invention discloses continuous hot galvanizing equipment of hot-rolled strip steel. The equipment comprises a waste heat utilization component, a heating section, a cooling box and a uniform heating section. One end of the heating section is connected with a uniform heating section. The other end of the heating section is connected with a sealing section. The waste heat utilization component is connected between the upper end of the heating section and the uniform heating section. In the invention, the waste heat utilization component is connected between the heating section and the uniform heating section, an exhaust fan conveys excess heat in the heating section into the uniform heating section through a heat conduction pipe, energy consumption needed by independent heating of the sealing section is reduced, and meanwhile waste heat reutilization of the heating section is improved. External cold air is blown into the box body through an air inlet fan, hot air in the box body is pumped away through the exhaust fan, cooling is accelerated through air circulation, cooling water circulates through heat conduction grooves arranged in a surfaces of a rotating roller and water circulation holes in an inner portion, hot-rolled strip steel is rapidly cooled, and production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of hot-dip galvanizing equipment, and in particular relates to continuous hot-dip galvanizing equipment for hot-rolled strip steel. Background technique [0002] Hot-rolled strip steel generally refers to coiled strip steel with a thickness of 1-20 mm and a width of 600-2000 mm. The hot-rolled steel strip can be used directly as a hot-rolled steel plate, or it can be supplied as a cold-rolled steel strip as a billet. It is widely used in automobile, electrical machinery, chemical industry, shipbuilding and other industrial sectors, and it is also used as a blank for cold rolling, welded pipe, and cold-formed steel production. Hot strip rolling mill is the main equipment for producing hot strip steel, which has the advantages of high production efficiency, high output and good quality. [0003] According to the product width and production process, there are four ways of hot-rolled strip steel: hot continuo...
