Description
本發明係關於一種用於鍍覆一產品、尤其係鍍覆金屬產品之方法，其中一熔融鍍層係施加至該產品之一表面並且其中該熔融鍍層之部分係由一導向該產品之氣流自該產品去除。此外，本發明係關於一種用於鍍覆一產品、尤其係金屬產品之裝置，其包括一鍍覆段，其中一熔融鍍層係施加至該產品之一表面；及一控制段，其中該控制段包含一用於自該產品去除該熔融鍍層部分之氣刀。
金屬片之連續熱浸鍍鋅係為吾人所熟知之技術。此方法包括在一連續程序中，熔融鍍層在金屬板之表面上的施加。金屬板通過熔融金屬液槽中。在槽中，金屬板之表面與熔融金屬反應以將鍍層結合在板的表面。當金屬片自金屬液槽中取出時，多餘之液態金屬亦結合在表面上。
在隨後之控制段中控制鍍層厚度。此厚度之控制係由氣體掃淨程序完成。氣體噴嘴將低壓、大容量空氣流輸送至金屬板之表面以去除剩餘的來自熔融金屬液槽之熔融金屬。因為氣體噴嘴"切斷"多餘鍍層材料，吾人經常將其稱為"氣刀"。
在下文中，術語"氣刀"將意指用於將氣體輸送至表面上或沿著表面輸送以去除剩餘鍍層材料之器件。因此術語"氣刀"及"氮氣刀"係指輸送用於氣體掃淨目的之空氣或氮氣的器件。一些鋼材生產商使用氮氣取代空氣作為在鋼鍍鋅方法中之掃淨氣體。氮氣之使用具有下列優點：由於氮氣之惰性，完成具有改良之表面品質的鍍層。但因為相比空氣掃淨技術，流型通常是不變的，亦即將低壓、高容積流量之氮氣導向金屬板，所以相關氣體的費用相對較高。
本發明之目的係提議一種方法以及一種裝置，用於具有靈活性增加的氣體掃淨。
此目的由一種鍍覆一產品之方法達成，其中一熔融鍍層係施加至該產品之一表面，且其中由一導向該產品之氣流將該熔融鍍層之部分從該產品上去除，其特徵為隨後將一第一氣流及一第二氣流導向該產品。
根據本發明，使用至少兩氣流以去除任何過量之熔融鍍層。第一及第二氣流係相繼導向產品。隨後將多於兩股之氣流導向產品亦係可能的。
現將參照鍍覆一金屬產品描述本發明。然而，熟習此項技術者將瞭解，下列敘述不局限於金屬產品，非金屬產品之鍍覆亦係合適的。
第一氣流及第二氣流宜在參數速度、壓力、容積、流型、溫度及/或組合物之至少一種上不同。
例如，首先將一具有高速及/或高壓之氣流導向較佳係金屬產品之產品，以掃淨過量鍍層之主要部分，接著使用一具有較低速度及/或較低壓力之氣流以達到期望之最終表面品質。第一氣體及第二氣體可係相同的氣體例如氮氣，或不同的氣體諸如空氣及氮氣。
替代或對第一及第二氣流使用不同的速度或不同的壓力之補充，藉由第一及第二氣刀使產品上被吹到分別不同氣體量亦係可能的。
可用於積極地影響掃淨處理之結果的另一參數係掃淨氣體之溫度。因此，在較佳具體實施例中使用不同溫度之第一及第二氣流。
在另一較佳具體實施例中，不同之氣體或不同之氣體組合物用於第一及第二氣流。例如，第一氣刀具有空氣，第二氣刀具有氮氣。另一實例中，分別提供氮氣及氬氣至第一及第二氣刀。
掃淨氣體宜選自群組：空氣、氮氣、氬氣、氦氣、氫氣、二氧化碳、或一氧化碳。
為第一氣流及/或第二氣流使用惰性氣體係較佳的。較佳之惰性氣體係氮氣及氬氣。
根據一較佳之具體實施例，一股空氣及一股氮氣被導向產品。根據此具體實施例，以氮氣執行所有氣體掃淨處理以便完成高品質之表面的鍍層不是必需的。發明者已顯示空氣刀技術與氮氣刀技術之組合、亦即以空氣及氮氣掃淨會提供與由氮氣刀技術達到的成果相當之一改良表面品質之鍍層。但由於降低使用之氮氣量，氣體耗量成本實質上係降低。
將空氣流以及氮氣流相繼導向該產品。首先使用空氣流去除過量熔融鍍層並且隨後將氮氣流導向該產物係尤佳的。計畫係：首先以空氣流將鍍層降低至特定之水準並且接著以氮氣完成掃淨。由於其惰性，氮氣係用於完成最終熔融鍍層以達到期望之表面品質。因此，無任何表面品質之損失，相比純氮氣刀之使用，本發明之方法降低所要求之氮氣量以及相關之氣體耗量成本。
為了達到特殊表面粗糙度或特殊表面品質或改變表面固化行為，首先使用空氣流並且接著使用氮氣流可係有利的。此外，為達到最大靈活性以改變鍍層之表面性質，同時施加空氣流以及氮氣流亦係可能有幫助的。
第一氣流與第二氣流之比在1比99及99比1之間較佳。尤其較佳地係將第一與第二氣流之比，例如空氣與氮氣之比設定在1:4及4:1之間，甚至更佳地係在1:3及3:1之間。
根據本發明之尤佳具體實施例，氮氣消耗量係在純氮氣刀系統之氮氣消耗量的30%及70%之間，較佳地在40%及60%之間，剩餘的較佳地係空氣。例如，用於氣體掃淨之總氣體之40%係氮氣，並且總氣體之60%係空氣。因此，氮氣消耗量係降低為純氮氣掃淨系統之消耗量的40%。
本發明較佳地係針對鍍覆狹長金屬製品，尤其係金屬條、金屬板或金屬線，例如鋼板或鋼板條，其係連續地輸送通過一鍍覆段，其中熔融鍍層施加至金屬製品之表面。將金屬條或金屬板或通常之狹長金屬製品運輸通過鍍液槽，其中來自鍍液槽之鍍層材料結合至金屬製品之表面。當狹長金屬製品離開液槽時，其拖出的鍍覆材料比鍍覆所需更多。因此，第一及第二氣流例如空氣及氮氣吹至表面上以去除過量之鍍覆材料並且達到期望之厚度。
將經過鍍覆之狹長金屬製品沿第一及第二氣刀連續通過係有利的，該等氣刀分別將第一及第二氣流吹至通過之金屬製品之表面上或沿其表面吹。
較佳地係將金屬鍍層施加至產品。較佳地，施加至產品、尤其係金屬製品之鍍層包括一或多種金屬或鋅、鋁、矽之群組之組合物。
特定言之，本發明係針對將產品鍍鋅，並且更佳地係針對鍍鋅金屬板或金屬條、尤其係鋼板或鋼板條。然而，本發明之方法亦可用於由熱浸鍍將其他鍍覆材料施加至金屬製品，亦即將金屬製品浸入鍍覆材料之液槽中。
當鍍覆如上所述之狹長產品時，自鍍液槽拖出之過量鍍覆材料之量係取決於金屬製品離開液槽之速度。速度越快，拖離液槽的鍍覆材料越多。本發明之方法適用處於1m/min及300m/min之間的產品之速度，即其很好地符合在標準熱浸鍍系統之速度範圍。
本發明之用於鍍覆一產品的裝置包括一鍍覆段，其中熔融鍍層施加至該產品之表面，尤其係金屬製品之表面；以及一控制段，其中該控制段包括一第一氣刀，用於自該產品去除該熔融鍍層之部分，並且其中該裝置之特徵為該控制段包含一第二氣刀，用於自該產品去除該熔融鍍層之部分。
本發明之裝置允許使用不同的氣體及/或不同的氣流以控制在該產品上的鍍層厚度。第一及第二氣刀可具有任何類型之氣體。本發明以一可獲得鍍層之要求厚度以及要求表面品質的方式給予設定第一及第二氣流消耗量的靈活性。
例如，本發明之裝置可以在0%及100%之間的空氣消耗量以及在0%及100%之間之氮氣消耗量操作。因此，有可能僅以空氣工作，僅以氮氣工作或以處於任何期望關係的空氣及氮氣工作。當表面要求增高，氮氣與空氣的比將增加，並且另一方面，當品質要求降低時，氮氣與空氣的比係下降以降低氮氣的消耗成本。
控制段包括運輸路徑係有利的，該產品係沿著路徑通過並且其中該第一氣刀以及該第二氣刀係沿該運輸路徑連續配置，以及其中該第二氣刀係位於該第一氣刀之下游。術語"下游"係參照產品之運輸方向。在離開鍍液槽之後，產品係沿著運輸路徑輸送通過控制段。在控制段中產品首先接受第一氣流、較佳地係由第一氣刀(空氣刀)提供之空氣流，並且接著接受透過第二氣刀輸送之第二氣流、較佳地係惰性氣流諸如氮氣流。
本發明及本發明之更多細節將參考圖式描述。
圖1顯示將鋼板條1鍍鋅之裝置。將鋼板條1運輸通過進口錐體2進入熔融鋅之鍍層或鍍鋅液槽3。在液槽3內，熔融鋅係結合至鋼表面。鋼板條1由沉沒輥4轉向並且以垂直方向離開鍍液槽3。
在鍍液槽3之上係控制段5，其包括空氣刀6及氮氣刀7。空氣刀6包括具有槽口9之腔室8。腔室8係連接至空氣供應10。氮氣刀7包括具有槽口12之腔室11以及氮氣供應13。
在操作中，鋼板條1以例如約150m/min之高速輸送通過鍍液槽3並且通過控制段5。在控制段5中，任何已經自鍍液槽3拖出之過量鋅14係如下所述由空氣及氮氣自鋼板條1上吹離。
空氣刀6係經供以壓縮空氣，接著透過槽口9吹出之空氣係吹至鍍覆鋼板條1之表面。產生之空氣噴流18類似刀運作，並且自鋼板條1之表面去除過量熔融鋅。自鋼板條1剝離之熔融鋅流動返回至鍍液槽3。
在氣刀6之槽口9之上，鍍層厚度已經降低至第一特定水準15。接著鍍層15接受氮氣噴流19，其徹底去除過量的鋅。此外，因為氮氣係惰性氣體，故產生具有高品質之表面的鍍層16。
為防止空氣自空氣刀6上升至氮氣刀7，空氣刀6以及氮氣刀7係經配置以使得亂流區17產生在二者之間。亂流區17擔當緩衝並且阻止空氣上升至氮氣刀7之出口12的區域。因此，由氮氣刀7執行之鍍層厚度最終降低係在實質上包括氮氣之大氣中執行。
供應至空氣刀6之空氣壓力及量以及供應至氮氣刀7之氮氣壓力及量係取決於鋼板條之速度、期望之鍍層厚度以及品質、及/或鍍層材料之類型來控制。可能用於操縱空氣之壓力及量之其他參數係在液槽3之上的空氣刀6的高度、自輸送中的鋼板條1至空氣刀6的距離、空氣刀6之角度、或槽口9之尺寸。
取決於期望之表面品質的要求，空氣流18與氮氣流19之比例可在1:5至5:1之間變化。
較佳地，氮氣消耗量係降低至純氮氣掃淨系統之30%至70%。換言之，導向鋼板條1的整體氣體中僅30%至70%係氮氣，或從另一角度來看，在純氮氣掃淨系統中使用之70%及30%之間的氮氣係由空氣替代。
