　　鋁(lv)型(xing)材(cai)淬(cui)火(huo)的(de)冷(leng)卻(que)速(su)度(du)除(chu)了(le)與(yu)鋁(lv)合(he)金(jin)的(de)特(te)性(xing)有(you)關(guan)外(wai)
，還(hai)與(yu)鋁(lv)型(xing)材(cai)擠(ji)壓(ya)製(zhi)品(pin)的(de)尺(chi)寸(cun)形(xing)狀(zhuang)有(you)關(guan)。壁(bi)厚(hou)薄(bo)的(de)鋁(lv)材(cai)產(chan)品(pin)降(jiang)溫(wen)速(su)度(du)快(kuai)，需(xu)要(yao)的(de)冷(leng)卻(que)速(su)度(du)低(di)
；壁厚厚的鋁材產品由於芯部熱量不易散出，需要較高的冷卻速度才能滿足淬火需求對於壁厚2．0mm 以下的鋁合金型材隻要能滿足工藝要求的可優先考慮用強風冷卻淬火；壁厚2．0mm以上的型材須用水冷淬火處理。淬火後要按標準要求的力學性能指標檢測力學性能
，達到標準的為工藝合格，否則再進行改進。

　　隨著近幾年的發展，現在有比較先進的自動化在線冷卻淬火係統
，生產起來比較容易。不過除6063以外的其它6xilvhejinjiyaxingcaiyaoqiudepinzhongjiaoduo，dingdanbijiaolingsan，suoshejidaodejiyajidunweicongxiaoxingdaodaxingdouyou。youjiashangzidonghuazaixianlengquecuihuoxitongjiageanggui，womenzanshibunenggeimeigexinghaodejiyajishangdoupeitaozhuangshangzidonghuazaixianlengquecuihuoxitong。weilejieyueshebeitouruchengben，womenzhaokailejishugongguanhuiyi，genjuzidonghuazaixiancuihuoxitongdeshengchanyuanli，laiyanjiuzijizhizuozaixiancuihuopenshuilengquezhuangzhilaishengchanzhexielvxingcai，binghuodelechenggong。
