系列鋁鑄軋機 Series aluminum casting and rolling machine
鑄軋機是把在經過靜置爐精煉后的鋁液,經靜置爐口Þ液面自動控制裝置Þ除氣箱內進一步精煉Þ過濾Þ前箱嘴子Þ相向轉動且內部通有循環冷卻水的鑄軋輥,使鋁液結晶并產生一定的變形率,從而實現鋁及鋁合金由熔融的液態金屬鑄軋成6~10 mm鑄軋板材,在經過切頭Þ卷取后,形成鑄卷帶材的工藝過程。通過鑄嘴的注口,將鋁液注入經冷卻水冷卻的軋輥上,鋁液沿軋輥表面寬向分布。這時,金屬處于稍前于軋輥中心線的輥縫處,使液態金屬在很短的時間內冷卻、凝固,完成整個鑄造結晶過程,接著受熱軋制成形,形成鑄軋板帶。在該過程中熔溶狀態鋁液的大量熱能被軋輥迅速帶走。
鑄軋機每側鑄嘴可水平和垂直進行單獨精確調整,確保軋出合格的鑄軋板材。
鑄軋機的每個軋輥都單獨由直流電機和行星齒輪減速箱驅動,同步控制由全數字式控制系統實現。
通過火焰噴涂系統在鑄軋輥表面不斷形成具有分離和潤滑作用的集碳,防止鋁液粘輥。鑄軋帶材離開輥縫后,通過導出輥、夾送輥、液壓剪、偏導輥,由直流電機驅動的下卷式卷取機進行卷取。卷取機可提供鑄軋板帶的張力。當帶材尺寸符合要求時,需在不停止鑄軋生產過程的情況下剪切帶材。為了完成這一操作過程,系統配有一套液壓驅動的夾送輥,以保持鑄軋機出口處的張力。該夾送輥在同步剪切機剪切前夾緊,在換卷后立即打開。卷材通過卸卷小車和液壓推卷裝置從卷取機上卸下卷材,完成整個鑄軋生產過程。

The casting and rolling machine is to further refine the liquid aluminum after being refined in a static furnace through the automatic control device of the liquid surface of the static furnace, and to further refine and filter the casting rolls of the forebox that rotate in the same way and have circulating cooling water inside, so that the liquid aluminum and aluminum alloy can be cast and rolled into 6-10 mm cast-rolled plates from molten liquid metal. The process of forming the cast strip after the cutting of þto. Through the nozzle of the casting nozzle, the liquid aluminum is injected into the roll cooled by the cooling water, and the liquid aluminum is distributed broadly along the surface of the roll. At this time, the metal is slightly in front of the roll center line of the roll gap, so that the liquid metal in a very short time to cool, solidified, complete the whole casting crystallization process, and then hot rolling forming, forming cast and rolled strip. In this process, a large amount of heat energy of molten aluminum is quickly removed by the roll.
Each side of the casting and rolling machine can be accurately adjusted horizontally and vertically to ensure that qualified casting and rolling sheet.
Each roll of the casting mill is driven by a DC motor and a planetary gear reducer, and synchronous control is realized by a full digital control system.
Through the flame spraying system on the surface of the casting roll continuous formation of separation and lubrication of carbon collection, to prevent the aluminum liquid sticking to the roll. After the cast - rolled strip leaves the roll gap, it is coiled by a down-coiler driven by DC motor through the export roll, the pinch roll, the hydraulic shear and the deflector roll. The coiler provides tension for the cast - rolled strip. When the strip size meets the requirements, the strip should be cut without stopping the casting and rolling process. To accomplish this process, the system is equipped with a set of hydraulically driven pinch rollers to maintain tension at the outlet of the casting mill. The clamping roll is clamped before cutting by the synchronous shearing machine and opened immediately after changing the roll. The coil is unloaded from the coiler by the unwinding trolley and the hydraulic coiling device to complete the whole casting and rolling production process.
