昆明質(zhì)量鍍鋅圓鋼哪家好鍍鋅圓鋼的生產(chǎn)制造有什么質(zhì)量要求？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="昆明質(zhì)量鍍鋅圓鋼哪家好,鍍鋅圓鋼"

二、冷拉強(qiáng)化的原理：鋼材在塑性變形中晶格的缺點(diǎn)增多，而缺點(diǎn)的晶格嚴(yán)重畸變對(duì)晶格進(jìn)一步滑移將起到阻礙作用，故鋼材的屈服點(diǎn)提高，塑性和韌性降低。由于塑性變形中產(chǎn)生內(nèi)應(yīng)力，故鋼材的彈性模量降低。將經(jīng)過冷拉的鋼筋于常溫下存放15～20d或加熱到100～200℃并保持一定時(shí)間，這個(gè)過程稱為時(shí)效處理。 </p> <p> 三、冷拉后時(shí)效處理的鋼筋，屈服點(diǎn)進(jìn)一步提高，抗拉極限強(qiáng)度也有所增長(zhǎng)，塑性繼續(xù)降低。由于時(shí)效過程中內(nèi)應(yīng)力的消減，故彈性模量可基本恢復(fù)。工地或預(yù)制構(gòu)件廠常利用這一原理，對(duì)鋼筋或低碳鋼盤條按一定制度進(jìn)行冷拉或冷拔加工，以提高屈服強(qiáng)度節(jié)約鋼材。 </p><p> 鍍鋅圓鋼與鋼管的區(qū)別 </p> <p> 鍍鋅圓鋼是指截面為圓形的實(shí)心長(zhǎng)條鋼材。其規(guī)格以直徑的毫米數(shù)表示，如"50"即表示直徑為50毫米的圓鋼。圓鋼分為熱軋、鍛制和冷拉三種。熱軋圓鋼的規(guī)格為5.5-250毫米。其中：5.5-25毫米的小圓鋼大多以直條成捆供應(yīng)，常用作鋼筋、螺栓及各種機(jī)械零件；大于25毫米的圓鋼，主要用于制造機(jī)械零件或作無縫鋼管坯，圓鋼與其它鋼筋的區(qū)別：外型不一樣，圓鋼外型光圓，無紋無肋，其它鋼筋表面外型有刻紋或有肋，這樣就造成圓鋼與混凝土的粘結(jié)力小，而其它鋼筋與混凝土的粘結(jié)力大。成份不一樣，圓鋼(一級(jí)鋼)屬于普通低碳鋼，其它鋼筋多為合金鋼。鍍鋅圓鋼的自身優(yōu)勢(shì)是什么？</p><div
