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(yán)格要求。冷拔方鋼具有足夠高的高溫強(qiáng)度和高溫塑性。在操作前，應(yīng)按常規(guī)對設(shè)備進(jìn)行檢查和空載運(yùn)轉(zhuǎn)一次。安裝拔絲模時(shí)，要分清正反面.安裝后應(yīng)將固定螺栓擰緊。為減少拔絲力和拔絲?？讚p耗，抽拔時(shí)須涂以潤滑劑。一般在拔絲模前安裝一個(gè)潤滑盒，使鋼筋黏滯潤滑劑進(jìn)入拔絲模。拔絲的成品，應(yīng)隨時(shí)檢查砂孔、溝痕、夾皮等缺點(diǎn)，以便隨時(shí)更換拔絲?；蛘{(diào)整轉(zhuǎn)速。
