高頻加熱：常用頻率為（200～300）KHZ，淬硬層深度為（0.5～2.5）mm。 </p> <p> 中頻加熱：常用頻率為（2500～8000）HZ，淬硬層深度為（2～10）mm。 </p> <p> <br /> </p> <p> 工頻加熱：電流頻率為50HZ，不需要頻設(shè)備，城市用交流電即可，硬層深度為（10～20）mm以上，城市用交流電即。 </p> <p> 鋼球感應(yīng)加熱優(yōu)缺點(diǎn)：感應(yīng)加熱表面淬火加熱速度快，生產(chǎn)率高，加熱溫度和淬硬層深度容易控制，鋼球表面氧化和脫碳少，鋼球變形小，可以使全部淬火過(guò)程實(shí)現(xiàn)機(jī)械化、自動(dòng)化。 </p><div style="width:100%;text-align: center;"><img

如果鋼球的表面呈黑紅色,證明鋼球經(jīng)過(guò)高溫回火處理了。如果鋼鐵球表面仍然帶有金屬本色,我們可以判斷鋼球沒有經(jīng)過(guò)高溫回火處理。 </p> <p> <br /> </p> <p> 一般來(lái)說(shuō),低鉻球含鉻量為0.5%到2.5%,含碳量從1.80%到3.20%。因此,根據(jù)國(guó)家標(biāo)準(zhǔn),低鉻球硬度應(yīng)該不小于45hrc，沖擊值應(yīng)該不小于1.5j/cm2。低鉻球也需要高溫度回火處理來(lái)保證質(zhì)量。這種處理可以消除鑄造應(yīng)力。如果鋼球的表面呈深紅色,表明經(jīng)過(guò)了高溫回火處理。如果表面仍然呈金屬本色,表明鋼球沒經(jīng)過(guò)高溫回火。 </p> <p> <br /> </p> <p> 鑄造鋼球通常是用于大規(guī)模開礦的各種水泥廠、化工廠、發(fā)電廠、石英砂廠、硅砂廠等。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇專業(yè)鋼球值得信賴"
