style="text-indent:25px">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的供應(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、無縫鋼管的管坯等。按化學(xué)成分分類：碳素鋼按化學(xué)成分可分為低碳鋼、中碳鋼和高碳鋼。(1)低碳鋼：又稱軟鋼，含碳量從0.10%至0.30%低碳鋼易于接受各種加工如鍛造，焊接和切削，常用于制造鏈條，鉚釘，螺栓，軸等。（2）高碳鋼：常稱工具鋼，含碳量從0.60%至1.70%，可以淬硬和回火。錘，撬棍等由含碳量0.75%的鋼制造；切削工具如鉆頭，絲攻，鉸刀等由含碳量0.90%至1.00%的鋼制造。宣城q345d圓鋼廠家合金圓鋼需要經(jīng)常擦拭，除去灰塵，保持清潔干燥。</p><div

style="text-indent:25px">鍛制圓鋼：是指可以通過鍛造成型的圓鋼。一般情況下，在相同變形比的條件下比自由鍛造軋制法生產(chǎn)的圓鋼的質(zhì)量要好，因?yàn)殄懺煲_(dá)到軋制相同的變形量需要反復(fù)鍛打才能拔長(鍛造是自由變形而軋制是約束變形)，所以相同的坯料生產(chǎn)相同的成品圓鋼鍛造相當(dāng)于軋制的變形比提高50%以上，另外一般來說鍛造是鋼件從表面到內(nèi)部整體變形而軋制表面先變形，所以兩者生產(chǎn)的圓鋼的內(nèi)部組織、偏析程度、金屬流線等完全不同，鍛制圓鋼的質(zhì)量一般優(yōu)于軋制圓鋼的質(zhì)量。所以吊車鉤頭等關(guān)鍵部件必須用鍛制件。合金圓鋼生產(chǎn)時(shí)工作人員要戴護(hù)目鏡。衢州cr12圓鋼非標(biāo)</p><p
