Influence of temperature and time on square tube performance:

At the same time, the heating temperature and time will also have a great impact on the performance of the square tube. During the operation of the circular furnace, the technical regulations should be strictly followed. The influence of temperature and time on the performance of the square tube should be checked frequently,

In order to ensure the stability of the piercing performance and chemical properties of square tube billets, the influence of temperature and time on square tube properties is generally rising, and it is easy to form a trend of batch quality problems. In case of abnormal conditions, timely handle them and make records of large drops, so that the chemical composition of square tube is unqualified (carbon content is unqualified), The heating of square tube blank is the key process to ensure that the square tube blank has enough plasticity to complete the smooth piercing. If the heating temperature is too high or the heating time is too long, the product qualification rate will be seriously affected.

The influence of temperature and time on the performance of the square tube shall be timely notified to the subsequent posts and the quality management department for tracking and disposal.
