英国原子能公司研制的“Conform”铝合金挤压法,在轻合金挤压工艺的发展中,又向前迈进了一步。挤压坯料为冷态轧制棒材,因此,这种挤压法的加热费用比热挤压法的约减少3/4。此法的另一优点是投资少,挤压机的价格约为20万磅,而热挤压设备则为60万磅。其挤压过程的特点是金属的损失少,金属的有效利用率达98.5%,而热挤压法的只有85%。用“Conform”法挤压时,是利用送料辊
British Atomic Energy Corporation developed the “Conform” aluminum extrusion method, light alloy extrusion process in the development, but also take a step forward. Extrusion billet cold rolling bar, therefore, this extrusion method of heating costs than the hot extrusion method to reduce about 3/4. Another advantage of this method is the low investment, the cost of the extruder about 200,000 pounds, and the hot extrusion equipment 600,000 pounds. The extrusion process is characterized by less metal loss, effective utilization of metal up to 98.5%, while the hot extrusion method is only 85%. With the “Conform” method of extrusion, the use of feed roller
