采用三辊斜轧穿孔法将铸态铝及铝合金制成毛管后,可直接进行冷加工,成品管机械性能达到YB611—66标准,效率、产量和质量等经济技术指标均比挤压管及空心锭轧制管更高,成本更低。
The three-roll cross-piercing method will be cast aluminum and aluminum alloy tube after the hair, can be directly cold-worked, finished tube mechanical properties to YB611-66 standards, efficiency, output and quality of economic and technical indicators than extruded tubes and hollow The ingot rolling tube is higher and the cost is lower.
