何謂球化退火？其工藝特點是什么？答：所謂鋼的球化退火是使鋼中的碳化物球化而進(jìn)行的退火工藝。通球化退火鋼中碳化物球狀化加熱溫度AC1+2-3保溫時間取決于工件透燒時間，但不宜長。冷卻速度一般在爐內(nèi)以1-2度/H冷卻，冷到55度以下出爐空冷。溫球化退火主要用于高碳工具鋼合金工具鋼。該工藝球化充分易控制，周期較短，事宜大件。加熱溫度為AC1+2-3度，保溫時間取決于工件透燒時間。

可見，泵的安全運行與整個國民經(jīng)濟(jì)的發(fā)展密切相關(guān)，泵的維護(hù)和檢修至關(guān)重要。維護(hù)的類型1.1事故后維護(hù)這種維護(hù)方法允許機(jī)械工作到有明顯故障發(fā)生，采取的措施是將損壞的設(shè)備或元件拆下來進(jìn)行修理或更新。這樣維修的費用高且浪費時間，耽誤正常生產(chǎn)。這種方法另一個缺點就是維修部門一直處于“救火隊”的緊張狀態(tài)，為了“快速反應(yīng)”，就必須準(zhǔn)備好各種零配件以供替換；配備更多維修工人來應(yīng)付突如其來的緊急情況。還有可能出現(xiàn)的情況是，這里的問題還沒完全解決，那里又出現(xiàn)了更嚴(yán)重的故障，工人被迫疲于奔命。
