Why metal recycling workers learn the basics of steel, we all know that the use of steel produced by the use of scrap metal. Therefore, the recovery, classification, processing and utilization of scrap metal come from the knowledge of steel and steel. Learn scrap metal knowledge, should first learn to understand our country to produce what kind of specifications of steel and steel, which is our metal recycling workers should learn the minimum knowledge. With these basic knowledge, we can learn from practice what kind of industrial products and which types, specifications, grades and chemical compositions of steel to use in practice. “Learning and surgery, not learning without skills,” the work of metal recycling
