The production capacity of roll manufacturers is expanding rapidly, and the type structure still nee

After years of development, now domestic roll manufacturers can produce all kinds of rolls with different raw materials, different standards and different types, meeting the needs of all kinds of rolling mills in China. Today, let's let the roll manufacturer Wuxi Taihu roll Xiaobian talk about the current situation of the rapid expansion of production capacity and the need to optimize the type structure of the roll industry.

Looking at the overall situation, the allocation skill level of domestic roll manufacturing industry has reached the advanced level at home and abroad. In particular, some advantageous enterprises represented by Sinosteel Xingji have continuously strengthened the process control method of "mechanization, automation, intelligence and digitization" in the roll production process, and have entered the forefront of roll manufacturing skills at home and abroad. However, there are still some small roll factories with small planning and poor strength, which are unable to change the current situation of backward equipment skills. They can only continue the backward production mode of high resource consumption and environmental pollution, and produce some common and conventional low-end products. After smelting, forging and heat treatment, the forged steel roll makes the working layer of the roll body have uniform, high hardness, high wear resistance and excellent anti accident ability, so as to ensure that the roll neck and roll body core have certain strength and high resistance. This is an issue worthy of attention in the overall development of China's roll manufacturing industry.

Nowadays, the large composite cast steel backup roll, semi high speed steel roll and excellent centrifugal composite roll independently developed by some large enterprises have approached or reached the advanced level at home and abroad. In addition, the joint venture between TISCO and Akers of Sweden, the joint venture between Yizhong and yiler of Germany, and the joint venture between Baosteel and Hitachi have accelerated the progress and development of roll making skills in China with the introduction of foreign capital and skills.

However, despite the continuous expansion of production capacity and the continuous progress of skills, China's roll manufacturing industry has not fully kept up with the progress of skills and structural optimization and adjustment of iron and steel industry in the optimization and adjustment of type structure. The low-end products are overproduced and the production ability of high-grade products is obviously lacking, such as high-speed steel and semi high-speed steel rolls. At present, only a few enterprises such as Sinosteel Xingji have batch production ability in China, and the market share is low; Due to the special standard of many new and proposed wide and thick plate mills with a height of more than 5m, the required super large operation rolls and backup rolls are still completely imported. Therefore, the overall manufacturing level of rolls in China still needs to be improved. In order to deal with the problem of equipping modern rolling mills with high-function rolls, it is necessary to continuously enhance the ability of independent innovation and accelerate the progress of science and technology and the development of new products.

OK, the above is the introduction of the rapid expansion of production capacity in the roll industry and the type structure still needs to be optimized. If you want to know more about the roll manufacturer, please pay attention to the roll manufacturer Wuxi Taihu roll Xiaobian.
