冷拔扁鋼是常見的一種用于加工機械零件的鋼材。扁鋼的表面光潔度對機械零件的使用性能有很大的影響，有的用戶對于鋼材的光潔度有著較高的要求，那么怎樣才能提高鋼材的表面光潔度呢？常用的三種措施：<span style="font-size:12px;">一、要選用質(zhì)量好的鋼料，如果鋼料質(zhì)量不好，本身存在折疊，或者表面有夾雜、嚴重的刮傷和裂縫，在修磨處有棱角，冷拔扁鋼拔制后經(jīng)延伸而容易出現(xiàn)折疊、裂縫等問題。</span><span style="font-size:12px;">二、在拔制前要清理管料上面的氧化鐵皮或其他質(zhì)硬的污物，為了防止產(chǎn)生中由于氧化鐵皮或其他質(zhì)硬的污物在拔制或矯直過程中壓入了鋼管表面，造成鋼管表面不平整。</span><span style="font-size:12px;">三、保持冷拔扁鋼生產(chǎn)場地、工具和潤滑劑等的清潔，防止氧化鐵皮和污物落到鋼管表面。</span> 冷拔鋼產(chǎn)品有哪些優(yōu)點？河南冷拔方鋼廠商</p><p style="text-indent:25px">冷拔鋼產(chǎn)品的種類型號有很多。河南冷拔方鋼廠商</p><p>
