在鍍鋅扁鋼軋制過程中，必須嚴格控制終軋溫度不低于900℃，，否則軋制力急劇增大，變形難以控制，產品尺寸不穩(wěn)定，特別是對周期尺寸影響十分明顯。為控制成品精度，K3孔型的出口厚度應控制在8.5±0.3mm，寬度應≥105mm。 </p> <p> 周期鍍鋅扁鋼若出現(xiàn)鐮刀彎則難以矯正。鍍鋅扁鋼廠家為提高成材率，必須防止軋制過程中這一現(xiàn)象的發(fā)生，主要方法有： </p> <p> 一、二架軋機必須調平輥縫，將橫向厚差減少到低限度，保證沿軋件寬度方向的延伸均勻; </p> <p> 二、鍍鋅扁鋼等軋件的冷卻應在特殊的冷床上進行，即“斜力冷卻”，以防止再度出現(xiàn)空間彎曲。 </p><p style="text-indent:25px"><p>鍍鋅扁鋼的價格大概在每噸幾千元，便宜的有一兩千元。<p>不同用途的鍍鋅扁鋼，價格也不盡相同。就用途而言，鍍鋅扁鋼作為成材可用于制箍鐵、工具及機械零件，建筑上用作房架結構件、扶梯。<p>鍍鋅工藝，熱鍍鋅也叫熱浸鋅和熱浸鍍鋅：是一種有效的金屬防腐方式，主要用于各行業(yè)的金屬結構設施上。是將除銹后的鋼件浸入500℃左右融化的鋅液中，使鋼構件表面附著鋅層，從而起到防腐的目的。熱鍍鋅工藝流程：成品酸洗-水洗-加助鍍液-烘干-掛鍍-冷卻-藥化-清洗-打磨-熱鍍鋅完工。熱鍍鋅是由較古老的熱鍍方法發(fā)展而來的，自從1836年法國把熱鍍鋅應用于工業(yè)以來，已經有一百四十年的歷史了。然而，熱鍍鋅工業(yè)是近三十年來伴隨冷軋帶鋼的飛速發(fā)展而得到了大規(guī)模發(fā)展。冷鍍鋅扁鋼冷作硬化更為明顯，可明顯提高材料的強度，熱鋼的冷加工硬化是沒有那么多。</p><div

外吹環(huán)角度要與磁輥成平行直角，縱向、橫向位置要正，保證鍍鋅管在風環(huán)中間通過。 </p> <p> 安裝磁力輥時，五個磁力輥上下左右必須在一條中心線上，保證外吹的后的鍍鋅管鋅層均勻。 </p> <p> 外吹采用壓縮空氣進行外吹，比較好采用70℃以上，壓力在0.2-0.4Mpa狀況下進行。 </p> <p> 在下列情況下應調整風壓： </p> <p> (1)、鍍鋅管外表面鋅層太厚。 </p> <p> (2)、外吹后鋅層表面發(fā)暗。 </p> <p> (3)、外吹后鋅層表面粘附著雜物和條狀不干凈物應調節(jié)風量。冷拉鋼不銹鋼坯坯原料生產冷，成品不銹鋼扁鋼熱軋，正火或熱軋酸洗（或砂），冷拉拋光狀態(tài)交貨。昆明鍍鋅扁鋼需要多少錢</p><p
