China's roller straightener market: growth trends, competition landscape and prospects
Roller straighteners are repetitive bending straighteners and are currently the most widely used straighteners. The roller straightening machine was invented on the basis of the pressure straightening machine. The theoretical basis of this invention and innovation is that under the condition of large elastic-plastic bending of metal materials, no matter how different the original bending degree is, the remaining residue after rebounding The difference in bending degree will be significantly reduced and even become consistent, thereby achieving the purpose of straightening.
The roller straightening machine industry has a shortage of technical talents, and the specialization of process technology is low. Under the continuous influence of the economy, the growth rate of industrial scale has slowed down, and the structural contradictions of insufficient high-end and excess of middle and low-end have become prominent. The number of new companies in the manufacturing industry is gradually increasing. In the future, new competitors will enter the market or existing competitors will increase production capacity, which will intensify market competition in this industry.
Affected by uncertain factors in the process of rolling, shearing, cooling, transportation, inventory, etc., the final finished medium and thick plates will deform and form corresponding shape defects. For example, due to uneven plate thickness and temperature during rolling, The cooling process causes plate defects such as longitudinal and transverse wavy bending, sickle-shaped bending, and concave-convex bending in the middle.
