On March 10, Guangxi Liuzhou Yinhai Aluminum Co., Ltd. (hereinafter referred to as "Liuzhou Yinhai Aluminum") first trial-produced ultra-thin hot-rolled coils with a thickness of 2.2mm successfully rolled off the assembly line.
According to the thickness, hot rolled coils with a thickness less than 4mm are called thin hot rolled coils. At present, the thickness of most thin hot-rolled coils in the national aluminum industry is concentrated in the range of 2.5mm to 4mm, and no more than 10 manufacturers control the thickness to 2.2mm. This time, Liuzhou Yinhai Aluminum produced 2.2mm*1529mm 3 series thin hot-rolled coils. Coil, can be called ultra-thin hot rolled coil, reaching the first-class level in the national aluminum industry. This thin-thickness hot-rolled coil is prone to deviations, waves, broken strips, loss of tension, etc. during the rolling process. It requires a stable and high centralized control system, fast rolling speed, and high final rolling temperature, making production difficult.
In order to ensure the success of this trial production, Liuzhou Yinhai Aluminum has adjusted and optimized a number of key process parameters several times, and formed the final production process plan after many discussions. With the encouragement and support of the company's leaders, various departments cooperated in the production process to strictly control various parameters, which provided a strong guarantee for the successful trial production of the product.
The 3 series thin hot-rolled coil with a specification of 2.2mm*1529mm was successfully rolled off the production line of the "1+4" hot strip mill, which gave full play to the equipment advantages of the "1+4" hot strip mill, further verifying Liuzhou The continuous improvement of Yinhai Aluminum's production capacity has provided strong support for the subsequent improvement of the company's product quality and quantity.
