id="dbzh9z7" class="box"><p><p> 發(fā)展歷史 </p> <p> 熱鍍鋅是由較古老的熱鍍方法發(fā)展而來，自從1836年法國把熱鍍鋅應(yīng)用于工業(yè)以來，已經(jīng)有170年的歷史了。然而近30年來，伴隨冷軋帶鋼的飛速發(fā)展，江西Q235槽鋼批發(fā)價格，熱鍍鋅工業(yè)得到了大規(guī)模發(fā)展。在各種保護(hù)鋼基體的涂鍍方法中，熱浸鋅是非常優(yōu)良的一種。它是在鋅呈液體的狀態(tài)下，經(jīng)過了相當(dāng)復(fù)雜的物理、化學(xué)作用之后，在鋼鐵上不僅鍍上較厚的純鋅層，而且還生成一種鋅鐵合金層。這種鍍法，江西Q235槽鋼批發(fā)價格，不僅具備了電鍍鋅的耐腐蝕特點(diǎn)，江西Q235槽鋼批發(fā)價格，而且由于具有鋅鐵合金層。還具有電鍍鋅所無法相比擬的強(qiáng)耐蝕性。因此這種鍍法特別適用于各種強(qiáng)酸、堿霧氣等強(qiáng)腐蝕環(huán)境中.

U型鋼(全稱：礦山巷道支護(hù)用熱軋U型鋼) U型鋼是一種橫截面像英文字母“U”的鋼鐵，有時橫截面呈日文字母“ひ”的形狀。主要特點(diǎn)：承受壓力大，支撐時間久，易安裝不易變形等特點(diǎn)。 </p> <p> 主要用途：主要用于礦井巷道、礦井巷道二次支護(hù)、以及穿山隧道的支撐支護(hù)等用途。作為制造巷道可縮性金屬支架的主要型鋼，在國內(nèi)外寬泛采用的都是U型鋼。槽鋼：槽鋼是截面為凹槽形的長條鋼材。槽鋼分普通槽鋼和輕型槽鋼。熱軋普通槽鋼的規(guī)格為5-40#。槽鋼按形狀又可分為4種：冷彎等邊槽鋼、冷彎不等邊槽鋼、冷彎內(nèi)卷邊槽鋼、冷彎外卷邊槽鋼依照鋼結(jié)構(gòu)的理論來說，應(yīng)該是槽鋼翼板受力，就是說槽鋼應(yīng)該立著，而不是趴著。槽鋼主要用于建筑結(jié)構(gòu)、車輛制造和其它工業(yè)結(jié)構(gòu)，槽鋼還常常和工字鋼配合使用。

槽鋼剪刃設(shè)計的基本依據(jù)是槽鋼成品孔型形狀，這種設(shè)計在剪切過程中易出現(xiàn)以下問題：一是槽鋼兩肩部與其他部分相比，相對較厚，所需剪切力也較大，剪刃磨損較快，剪刃使用一段時間后。這一部分相對磨損量大，致使肩部間隙較大，易出現(xiàn)塌肩現(xiàn)象。 </p> <p> 考核槽鋼性能的檢驗項目主要為拉伸試驗和彎曲試驗，指標(biāo)包括屈服點(diǎn)、抗拉強(qiáng)度、延伸率及彎曲合格等項。 </p> <p> ①槽鋼的高度h、腿寬度b、腰厚度d尺寸允許偏差應(yīng)符合表2的規(guī)定。 </p> <p> ②槽鋼平均腿厚度的允許偏差為±0.06t。 </p> <p> ③槽鋼的彎腰撓度不應(yīng)超過0.15d。 </p> <p> ④槽鋼腿的外緣斜度，單腿不大于1.5%b，雙腿不大于2.5%b。 </p> <p> ⑤槽鋼腿端、肩鈍化不得使直徑等于0.18t的圓棒通過。<br /> 歡迎廣大新老客戶致電咨詢 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
