Therefore, in the field production process, in order to improve the sizing precision of the casting blank to 0-3cm, the casting blank needs to be artificially thermally re-sized after the infrared sizing system finishes cutting, namely, the real length of the high-temperature casting blank is measured by the roller way after cutting by using a special re-sizing tool, and then the infrared sizing system is subjected to data feedback and adjustment according to the real length to improve the sizing precision of the casting blank produced later. The hot re-ruler operation needs to be repeated and carried out at fixed time intervals, and generally needs to be carried out once every 2 to 3 hours.
