The pre plated nickel steel strip produced in this project undergoes high-temperature annealing treatment, and the steel layer and nickel layer will penetrate each other to form a nickel iron alloy layer, greatly improving the mechanical, corrosion and heat resistance properties of the nickel plated steel strip. It has better processing performance and is more suitable for large-scale continuous production. Through technological research and development improvement, our company has successfully developed a complete set of mass production equipment, which can produce a wide range of products, reduce production process flow and losses, have a high degree of automation, are more environmentally friendly, and have a more obvious cost advantage. The customer group is relatively focused, and the market can be rapidly expanded and expanded.。
