| Abstract: | Copper is one of the most important elements in the atmospheric corrosion resisting steel used for vehicle. However, copper is prone to enrichment around grain boundaries in copper containing steel, which leads to the formation of net like surface cracking called copper brittleness. Through researching on the smelting technology, overheating temperature and heating rate, a smelting technology and a special heating method, called high temperature and quick reheating process, were applied to the copper containing steel for hot rolled plate. The methods proved reasonable and feasible and the defects were effectively reduced. |
