the Introduction of Aluminum Forging
Forging is a kind of metal thermal processing techinology that human beings grasp relatively early,with a history of about 6000 years,China entered the heyday of brozon casting about 1700-1000BC,and craft reach a relatively high level.Forging is the method of casting the liquid metal into the forging cavity suitablevfor the shape of the part and obtaining the part of blank after it is cooled and solidified.
锻造是人类把握比较早的一种金属热加工工艺,已有6000年的历史。中国大约在公元前1700-前1000年进入青铜铸件的全盛期,工艺上已达到相当高的水平。锻造是是将液体金属浇铸到与零件外形相适应得锻造空腔中,待其冷却凝固后,以获得零件或毛坯的方法。
Most of the materials to be cast are originally solid metals heated to liquid(eg.copper,iron,aluminum,tin,etc...)and the material of the mold can be sand,metal or even ceramic.The methods used may vary according to different requirement.
被铸物质多为从固态加热至液态的金属(例:铜,铁,铝,锡等),而铸模的材料可以是砂,金属甚至陶瓷。因不同要求,使用的方法也有所不同。
