冷拔扁鋼在生產(chǎn)過程中，它的尺寸、使用性能、外觀質(zhì)量等都需要按照相關(guān)的技術(shù)標(biāo)準(zhǔn)來進(jìn)行生產(chǎn)，這樣才能夠滿足多種工況的使用要求。康宏機(jī)械給大家講解一下扁鋼的表面質(zhì)量要求是怎樣的：<span style="font-size:12px;">1.冷拔扁鋼表面應(yīng)潔凈、光滑。不允許裂紋、折疊、結(jié)疤、夾雜、拉裂和氧化皮。</span><span style="font-size:12px;">切削加工用扁鋼，表面上允許有深度不超過實(shí)際尺寸算起的該公稱尺寸公差的麻點(diǎn)、刮傷、拉痕、黑斑、凹面、清理斜痕、潤滑劑痕跡和深度為公差二分之一的個別小發(fā)紋。</span><span style="font-size:12px;">非切削加工用扁鋼，表面上允許有深度不超過從實(shí)際尺寸算起的該公稱尺寸公差的個別的刮傷、拉痕、麻點(diǎn)、黑斑、凹面及清理斜痕。</span> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

冷拔圓鋼也稱為冷拔元鋼，冷拔園鋼，冷拔光元，是冷拔型鋼的一種。規(guī)格從Ф4-Ф60，冷拔圓鋼材質(zhì)有A3，20，35，45，Q215-235，20Cr，40Cr，20CrMnTi，16Mn等。可按客戶要求通過精密模具，拔出各種規(guī)格精度高，表面光滑的冷拔圓鋼。我們會根據(jù)冷拔圓鋼的不同品種和要求，對其進(jìn)行鍛制，主要有以下方法：<span style="font-size:12px;">1、模鍛。對承插焊和螺紋的三通、四通、彎頭等小尺寸圓鋼，其外形相對復(fù)雜，應(yīng)采用模鍛成形工藝制造。自由鍛。對特殊形狀的圓鋼或不宜采用模鍛成形的圓鋼可用自由鍛工藝制造。切削加工等。</span> </p></p><br /><p>文章來源地址:
