style="text-indent:25px">在操作冷拔機時，當鋼坯的端經過冷拔模具之后，應當馬上分開離合器。與此同時，拉下手閘，將鋼坯壓住，使其緩慢通過，以防止人員受傷。還有放線架、滾筒等運轉情況也要注意。冷拔圓鋼生產加工有哪些事項需要注意的呢？對直徑較小的冷拔圓鋼進行冷拔前，應首先用扎頭機將圓鋼的頭部軋小，以方便下一步的冷拔操作，在扎頭時要注意切勿傷到手。操作冷拔機作業(yè)時，工作人員合上離合器之后，退到距離冷拔機直徑半米的范圍之外，手臂部位應當距離軋輥半米，作業(yè)過程中禁止觸摸冷拔圓鋼和滾筒。</p><p style="text-indent:25px">冷拔方鋼的工作條件是十分惡劣的，因而作為高壓鍋爐用管除了對性能、庭量有一般要求外，還要有一些特殊的嚴格要求。冷拔方鋼具有足夠高的高溫強度和高溫塑性。在操作前，應按常規(guī)對設備進行檢查和空載運轉一次。安裝拔絲模時，要分清正反面.安裝后應將固定螺栓擰緊。為減少拔絲力和拔絲?？讚p耗，抽拔時須涂以潤滑劑。一般在拔絲模前安裝一個潤滑盒，使鋼筋黏滯潤滑劑進入拔絲模。拔絲的成品，應隨時檢查砂孔、溝痕、夾皮等缺點，以便隨時更換拔絲模或調整轉速。冷拔鋼在存放時需要注意什么？</p><div

冷拔異型鋼因形狀多變，有很多種型號，而按照鋼管截面形狀尺寸的不同又可分為等壁厚冷拔異型鋼（代號為D）、不等壁厚冷拔異型鋼（代號為BD）、變直徑冷拔異型鋼（代號為BJ）。異型無縫鋼管普遍用于各種結構件、工具和機械零部件。和圓管相比，冷拔異型鋼一般都有較大的慣性矩和截面模數，有較大的抗彎抗扭能力，可以很大程度上減輕結構重量，節(jié)約鋼材。新鄉(xiāng)市康弘機械有限公司生產銷售的冷拔異型鋼產品型號齊全，多樣，且價格適中，質量好。
