鑄造鋼球因材料以及加工工藝的不同，熱處理內(nèi)外淬透性差，生產(chǎn)處理鋼球內(nèi)外硬度差別大。 </p> <p> 因?yàn)殄懺熹撹F有高碳錳鉻等合金元素合理搭配，生產(chǎn)熱處理內(nèi)外淬透性強(qiáng)，內(nèi)外硬度差別小，還因沖擊值的差別。因此決定鍛球與鑄造球相比更加不破碎。 </p> <p> 鍛造鋼球破碎率小，而鑄造鋼球破碎率大，一般情況鑄造鋼球破碎率在3%，而鍛造鋼球在1%，由于破碎率小，增加了磨機(jī)的出粉率，并減少了選礦成本，就提高了磨機(jī)生產(chǎn)效率。 </p> <p> 由于我們的鍛造鋼球金相組織是細(xì)針狀馬氏體組織，硬度較高，與鑄造鋼球同等耐磨性能下，鍛造鋼球價(jià)格遠(yuǎn)遠(yuǎn)低于鑄造鋼球，研磨成本更低。 </p><p

先來了解一下**基礎(chǔ)的滾珠軸承結(jié)構(gòu)吧—— </p> <p> 滾珠軸承主要包含四個(gè)基本元件：軸承滾珠（ball）、軸承內(nèi)環(huán)（inner ring）、軸承外環(huán)（outer ring）與軸承保持器（cage or retainer）。 </p> <p> 一般工業(yè)用的滾珠軸承滿足AISI52100的標(biāo)準(zhǔn)，軸承滾珠與軸承環(huán)通常是以高鉻鋼制成，洛氏硬度（Rockwell C- scale hardness）約在61-65之間。鋼球可以用在汽車安全帶里。浙江通用鋼球服務(wù)至上</p><p

球化退火加熱溫度為727度以上，保溫后等溫冷卻或直接緩慢冷卻。在球化退火時(shí)奧氏化是“不完全”的，只是片狀珠光體轉(zhuǎn)變成奧氏體，及少量過剩碳化物溶解。因此，它不可能消除網(wǎng)狀碳化物，如過共析鋼有網(wǎng)狀碳化物存在，則在球化退火前須先進(jìn)行正火，將其消除，才能保證球化退火正常進(jìn)行。 </p> <p> 普通球化退火是將鋼加熱到Ac1以上20～30℃，保溫適當(dāng)時(shí)間，然后隨爐緩慢冷卻，冷到500℃左右出爐空冷。等溫球化退火是與普通球化退火工藝同樣的加熱保溫后，隨爐冷卻到略低于Ar1的溫度進(jìn)行等溫，等溫時(shí)間為其加熱保溫時(shí)間的1.5倍。等溫后隨爐冷至500℃左右出爐空冷。和普通球化退火相比，球化退火不僅可縮短周期，而且可使球化組織均勻，并能嚴(yán)格地控制退火后的硬度。山東口碑好鋼球免費(fèi)咨詢</p><p
