Annealing galvanizing process flow of galvanized packaging steel strip.
The galvanizing method is now widely used in different fields. Its processing characteristics are simple, and the products are recognized by people. There are many kinds of galvanizing methods, one of which is called the annealing method. Its characteristics are:
1 Improved Sendzimir method, because there are preheating section and open flame heating section, so it has the characteristics of shortening the furnace length and high heating. The open flame can also burn part of the rolling oil, reducing the burden of strip pre-processing.
2 US Steel Union method, because it uses a full-radiation furnace for heating, it is easy to control the atmosphere in the furnace and the temperature of each zone. This method has higher requirements for pre-treatment of the strip, and the quality of the final product is also highly responsive.
3 The difference between the galvanizing annealing furnace and the aluminum-zinc-silicon annealing furnace is that the galvanizing line requires a cooling section that is much stronger than the aluminum-zinc-silicon plating; the aluminum-zinc-silicon plating also requires an equalization section after the cooling section. The difference between galvanizing and aluminum-zinc-silicon plating is determined by the production process. In addition, if it is necessary that both annealing furnaces can be used, the aluminum-zinc-silicon production line can be designed to increase the capacity of the cooling section.
The radiation furnace and cooling section of the 4-horizontal annealing furnace are modular in design and optimized for Baidu keyword ranking, which is easy to install and maintain.
5 uses an efficient circulating jet cooler, which has the characteristics of small footprint, high efficiency, uniform cooling, safety and reliability. And adopts modular design, according to the capacity of the furnace can increase or reduce the number of modules, so as to control the cooling capacity of this furnace.
