What are the characteristics of the heating and hot rolling process of copper alloy ingot processing
What are the characteristics of the heating and hot rolling process of copper alloy ingot processing?The ingot is brittle in the medium temperature range of 200-300℃, and related studies have shown that it is caused by impurity hydrogen or phosphorus.Because both hydrogen and phosphorus are surface active elements, they are easily adsorbed on the grain boundaries of copper and cause medium temperature brittleness.　　In order to improve production efficiency.Reduce the oxidation loss and ensure the normal rolling of the strip. Under the conditions of the copper alloy ingot processing equipment, the production of transformer strips generally adopts the conditions of “high temperature, rapid, uniform, neutral or slightly reducing atmosphere”. Rolling.　　The heating of copper alloy ingot processing generally adopts a walking heating furnace, and the temperature of the discharged material should be controlled at 850-920℃.Ensure that the ingot temperature is uniform to prevent overheating or overburning.The hot rolling billet temperature is higher than 820℃, and the final rolling temperature is not lower than 600℃.　　In order to avoid “hydrogen embrittlement” and hot rolling cracking during the processing and customization of copper products, the atmosphere should be controlled in a neutral or slightly reducing atmosphere by adjusting the air-fuel ratio, combustion degree, and furnace pressure..Consulting Hotline: 139-3883-7628.The content of the article comes from the copper alloy ingot processing network: www.lygety.com/
