熱鍍鋅方管均勻變形是物體變形的很簡(jiǎn)單情況，其特點(diǎn)是：平面與敘線在變形后仍為平面與直線.平行線與平行平面在變形后仍保持平行，與應(yīng)變主軸方向相垂直的立方體.在均勻變形后*有線性尺于的改變而無(wú)剪變形產(chǎn)生，變形體若為球面.變形后則為橢球面。 </p> <p> 由此可見(jiàn).均勻變形的特征表現(xiàn)為物體各點(diǎn)的位移是原始坐標(biāo)的線性函數(shù)，均勻變形只有三個(gè)主應(yīng)變而無(wú)剪切應(yīng)變。 </p> <p> 熱鍍鋅方管在金屬壓力加工理論中.特別是在軋管理論中.普遍采用對(duì)數(shù)應(yīng)變來(lái)表示均勻變形。對(duì)數(shù)應(yīng)變較相對(duì)變形系性能更準(zhǔn)確地表示物體的變形程度。低壓流體輸送用熱鍍鋅方管也稱一般焊管，俗稱黑管。是用于輸送水、煤氣、空氣、油和取暖蒸汽等一般較低壓力流體和其他用途的焊接鋼管。鋼管接壁厚分為普通鋼管和加厚鋼管;接管端形式分為不帶螺紋鋼管和帶螺紋鋼管。鋼管的規(guī)格用公稱口徑表示，公稱口徑是內(nèi)徑的近似值，昆明經(jīng)開(kāi)區(qū)薄壁熱鍍鋅方管價(jià)格表。習(xí)慣上常用英寸表示，昆明經(jīng)開(kāi)區(qū)薄壁熱鍍鋅方管價(jià)格表，如

熱鍍鋅方管易出現(xiàn)折疊。折疊是熱鍍鋅方管表面形成的各種折線，這種缺陷往往貫穿整個(gè)產(chǎn)品的縱向。產(chǎn)生折疊的原因是由于廠家追求高效率，壓下量偏大，產(chǎn)生耳子，下一道軋制時(shí)就產(chǎn)生折疊，折疊的產(chǎn)品折彎后就會(huì)開(kāi)裂，鋼材的強(qiáng)度大下降。 </p> <p> 熱鍍鋅方管外表經(jīng)常有麻面現(xiàn)象。麻面是由于軋槽磨損嚴(yán)重引起鋼材表面不規(guī)則的凹凸不平的缺陷。由于熱鍍鋅方管廠家要追求利潤(rùn)，經(jīng)常出現(xiàn)軋槽軋制超標(biāo)。 </p> <p> 熱鍍鋅方管表面易產(chǎn)生結(jié)疤。原因有兩點(diǎn)：(1)．熱鍍鋅方管材質(zhì)不均勻，雜質(zhì)多。(2)。廠家導(dǎo)衛(wèi)設(shè)備簡(jiǎn)陋，容易粘鋼，這些雜質(zhì) </p> <p> 材表面易產(chǎn)生裂紋，原因是它的坯料是土坯，土坯氣孔多，土坯在冷卻的過(guò) 程中由于受到熱應(yīng)力的作用，產(chǎn)生裂痕，經(jīng)過(guò)軋制后就有裂紋。 </p> <p> 熱鍍鋅方管容易刮傷，原因是熱鍍鋅方管廠家設(shè)備簡(jiǎn)陋，易產(chǎn)生毛刺，刮傷鋼材表面。深度刮傷降低鋼材的強(qiáng)度。 </p> <p> 熱鍍鋅方管無(wú)金屬光澤，呈淡紅色或原因有兩點(diǎn)二、它的坯料是土坯。材軋制的溫度不標(biāo)準(zhǔn)，他們的鋼溫是通過(guò)目測(cè)的，這樣無(wú)法按規(guī)定的奧氏體區(qū)域進(jìn)行軋制，鋼材的性能自然就無(wú)法達(dá)標(biāo)。 </p> <p>
