Research on Preventing Copper-Brittleness Process for Hot Rolling Copper-Containing of Atmospheric Corrosion-Resisting Steel Used in Vehicles

Abstract:

Copper in hot rolling copper-containing steel plate can passivate the cathode-anode of corrosion reaction on plate surface and form a dense anti-rusting layer, so the rusting reaction is postponed and prevented, and the corrosion resistance is enhanced. However, copper enrichment around grain boundaries in copper-containing steel plate leads to the formation of net-like surface cracking called copper-brittleness. In this paper, through researching the technologies of smelting, and adding rare earth and heating, a reasonable and feasible production technology is found, which effectively prevents the defect of copper-brittleness.
