style="text-indent:25px">合金圓鋼在進(jìn)行軋制的過(guò)程中材質(zhì)比較容易受到各方面的影響，合金圓鋼材質(zhì)的影響。相同的含氫量，不同材質(zhì)有著不同表現(xiàn)，有些材質(zhì)對(duì)白點(diǎn)敏感，就很容易出現(xiàn)白點(diǎn)。工件裝夾是可能出現(xiàn)問(wèn)題的另一個(gè)因素。對(duì)合金圓鋼進(jìn)行攻絲時(shí)，應(yīng)保證工件的裝夾剛性，防止工件振動(dòng)。螺孔的尺寸和質(zhì)量也是影響加工的關(guān)鍵因素。標(biāo)準(zhǔn)規(guī)定2B(英制內(nèi)螺紋精度等級(jí))小徑的螺紋高度是65%-83.3%。高度的螺紋則是一個(gè)完美的三角形。攻制65%的螺紋時(shí)，需要切除的材料量要少于攻制83.3%的螺紋，而絲錐切除的材料量越少，所需的扭矩就越小，絲錐壽命也越長(zhǎng)。</p><p style="text-indent:25px">對(duì)圓鋼的晶粒度和淬透性的影響：影響奧氏體晶粒度的因素很多。圓鋼的脫氧和合金化情況均與“奧氏體本質(zhì)晶粒度”有關(guān)。一般來(lái)說(shuō),一些不形成碳化物的元素,如鎳、硅、銅、鈷等,阻止奧氏體晶粒長(zhǎng)大的作用較弱,而錳、磷則有促進(jìn)晶粒長(zhǎng)大的傾向。碳化物形成元素如鎢、鉬、鉻等，對(duì)阻止奧氏體晶粒長(zhǎng)大起中等作用。強(qiáng)碳化物形成元素如釩、鈦、鈮、鋯等，強(qiáng)烈地阻止奧氏體晶粒長(zhǎng)大，起細(xì)化晶粒作用。鋁雖然屬于不形成碳化物元素，但卻是細(xì)化晶粒和控制晶粒開(kāi)始粗化溫度的較常用的元素。合金圓鋼生產(chǎn)時(shí)工作人員要戴護(hù)目鏡。</p><div
