The working conditions of excavators, bulldozers, crawler cranes and other equipment in construction machinery are harsh, especially the crawlers in the walking system at work need to withstand greater tension and impact. In order to meet the mechanical properties of the crawler, it is necessary to perform thermal processing including heat treatment, forging, casting and other processes on the many parts that make up the crawler. The above-mentioned thermal processing processes are all energy-intensive processing methods. Therefore, the use of new energy, new technology, and optimized technology has become an important way to continuously improve product performance and reduce manufacturing costs, while continuously improving product service life. Become an effective way to save energy.
