style="text-indent:25px">冷軋是在常溫狀態(tài)下由熱軋板加工而成，雖然在加工過程因為軋制也會使鋼板升溫，盡管如此還是叫冷軋。由于熱軋經(jīng)過連續(xù)冷變型而成的冷軋，在機(jī)械性能比較差，硬度太高。必須經(jīng)過退火才能恢復(fù)其機(jī)械性能，沒有退火的叫軋硬卷。軋硬卷一般是用來做無需折彎，拉伸的產(chǎn)品，海南耐磨鋼板。冷軋：用熱軋鋼卷為原料，經(jīng)酸洗去除氧化皮后進(jìn)行冷連軋，其成品為軋硬卷，由于連續(xù)冷變形引起的冷作硬化使軋硬卷的強(qiáng)度、硬度上升、韌塑指標(biāo)下降，海南耐磨鋼板，因此沖壓性能將惡化，只能用于簡單變形的零件。軋硬卷可作為熱鍍鋅廠的原料，因為熱鍍鋅機(jī)組均設(shè)置有退火線。軋硬卷重一般在6~13.5噸，鋼卷在常溫下，海南耐磨鋼板，對熱軋酸洗卷進(jìn)行連續(xù)軋制。內(nèi)徑為610mm。彩鋼板表面的油漆主要作用是防腐和美觀。海南耐磨鋼板</p><div

style="text-indent:25px">15號鋼其塑性、韌性高，但強(qiáng)度、硬度較低，鍛造、焊接和冷沖壓性能良好，冷變形塑性高，但切削加工時不易得到光潔的表面。用于制造受力不大、韌性要求高的零件和滲碳件，緊固件和沖模鍛件以及不經(jīng)熱處理的低負(fù)荷零件。15號鋼板化學(xué)成份：C :0.12～0.19；Mn :0.35～0.65；P :≤0.035；S :≤0.035；Cr :≤0.25；Ni :≤0.25；Cu :≤0.25；Si :0.17～0.37。15號鋼板區(qū)別20號鋼區(qū)別：兩種鋼材都屬于低碳鋼。從數(shù)據(jù)上來看，20號鋼含碳量稍高一些，兩者的金相組織都是珠光體+鐵素體。</p><p style="text-indent:25px">合金元素對鋼板熱處理的影響：合金元素的加入會影響鋼在熱處理過程中的組織轉(zhuǎn)變。合金元素對加熱時相轉(zhuǎn)變的影響，合金元素影響加熱時奧氏體形成的速度和奧氏體晶粒的大小。對奧氏體形成速度的影響： Cr、Mo、W、V等強(qiáng)碳化物形成元素與碳的親合力大, 形成難溶于奧氏體的合金碳化物, 明顯減慢奧氏體形成速度；Co、Ni等部分非碳化物形成元素, 因增大碳的擴(kuò)散速度, 使奧氏體的形成速度加快；Al、Si、Mn等合金元素對奧氏體形成速度影響不大。覆膜板表面光澤鮮艷，可挑選的花色品種多，改變了以往板材純色和色澤單一的特性。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">合金鋼板的性能：隨著科學(xué)技術(shù)和工業(yè)的發(fā)展，對材料提出了更高的要求，如更高的強(qiáng)度，抗高溫、高壓、低溫，耐腐蝕、磨損以及其它特殊物理、化學(xué)性能的要求，碳鋼已不能完全滿足要求。碳鋼的不足：(1)淬透性低。一般情況下，碳鋼水淬的較大淬透直徑只有10mm-20mm。(2) 強(qiáng)度和屈強(qiáng)比較低。如普通碳鋼Q235鋼的σs為235MPa，而低合金結(jié)構(gòu)鋼16Mn的σs則為360MPa以上。40鋼的 σs /σb*為0.43, 遠(yuǎn)低于合金鋼。(3) 回火穩(wěn)定性差。由于回火穩(wěn)定性差，碳鋼在進(jìn)行調(diào)質(zhì)處理時，為了保證較高的強(qiáng)度需采用較低的回火溫度，這樣鋼的韌性就偏低；為了保證較好的韌性，采用高的回火溫度時強(qiáng)度又偏低，所以碳鋼的綜合機(jī)械性能水平不高。(4) 不能滿足特殊性能的要求。碳鋼在抗氧化、耐蝕、耐熱、耐低溫、耐磨損以及特殊電磁性等方面往往較差，不能滿足特殊使用性能的需求。塑料復(fù)合鋼板常用于制作空氣潔凈系列和溫度為-10+70攝氏度的通風(fēng)系統(tǒng)的風(fēng)管和配件。海南耐磨鋼板</p><p
