不銹鋼珠性能：硬度達到56—58度，有磁性，耐腐蝕性好，耐磨性和韌性強 </p> <p> 不銹鋼珠應用：鋼珠金屬磨料的一種，主要品種有不銹鋼丸、鑄鋼丸、鋁丸、鋼絲切丸、研磨丸、銅丸，鋼珠廣泛應用于有色金屬壓鑄件、澆鑄件，鋁型材、汽車零部件、機械制造業(yè)、五金、泵閥行業(yè)的表面處理。主要集中于去產(chǎn)品表面氧化皮、邊緣表面毛刺、表面粗糙化、亞光郊果、平整強化、除銹處理。 </p> <p> 鋼珠：鋼珠主要用于高要求高亮度的鋁合金，不銹鋼等產(chǎn)品拋光。鋼珠分不銹鋼和研磨碳鋼兩種，不銹鋼鋼珠使用很方便，無須防銹，碳鋼鋼珠許要防銹！ </p> <p> 應用領域：不銹鋼拋光球通常用于各種五金件的去毛疵及拋光，從而使工件達到光滑光亮的效果：銅件、鋁件、銀器等等。另外鋼球也可以用來研磨藥材，上海專業(yè)鋼球值得信賴，上海專業(yè)鋼球值得信賴、化工原料。 </p> <p> 特性：任何一種鋼球均可用來拋光，但具體選用哪種材料哪種規(guī)格要根據(jù)工件的尺寸，上海專業(yè)鋼球值得信賴、形狀及性能來確定，通常拋光球選用4MM不銹鋼球。鋼球經(jīng)過熱處理后，鋼球的金相組織、硬度和壓碎負荷比沒有經(jīng)過熱處理的鋼球好。上海專業(yè)鋼球值得信賴</p><div style="width:100%;text-align:

低溫回火又稱“消除應力回火”?；鼗饻囟确秶鸀?50-250攝氏度，回火后的組織為回火馬氏體。鋼具有高硬度和高耐磨性，但內應力和脆性降低。經(jīng)滲碳和表面淬火的零件，回火后的硬度一般為58-64HRC。 </p> <p> 鋼球回火時間： </p> <p> 回火時間應包括按工件截面均勻地達到回火溫度所需加熱時間以及按M參數(shù)達到要求回火硬度完成組織轉變所需的時間，如果考慮內應力的消除，則尚應考慮不同回火溫度下應力弛豫所需要的時間。 </p> <p> <br /> </p> <p> 對以應力弛豫為主的低溫回火時間應比表列數(shù)據(jù)長，長的可達幾十小時。對二次硬化型高合金鋼，其回火時間應根據(jù)碳化物轉變過程通過試驗確定。當含有較多殘余奧氏體，而靠二次淬火消除時，還應確定回火次數(shù)。浙江直銷鋼球值得信賴研磨鋼球，顧名思義就是用于研磨東西的鋼球,就是一種研磨介質。</p><div style="width:100%;text-align:

</p> <p> 高鉻球的含鉻量是大于等于10.0%。含碳量在1.80%和3.20%之間。根據(jù)國家標準,高鉻球硬度必須不小于58hrc,沖擊值應大于等于3.0j/cm2。若達此硬度高鉻球必須用高溫淬火和回火處理。目前國內高鉻球淬火有兩種方法包括油淬火和風力淬火。如果高鉻球測試硬度低于54HRC，就意味著它沒有經(jīng)過淬火處理。 </p> <p> <br /> </p> <p> 中鉻球質量指標 </p> <p> <br /> </p> <p> 中鉻球規(guī)定含鉻量范圍從3.0%到7.0%,含碳量在1.80%和3.20%之間。它的沖擊值應不小于2.0j/cm2。國家標準要求中鉻球硬度應該大于等于47hrc。為確保質量,中鉻球應經(jīng)高溫回火處理消除鑄造應力。 </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。在球化退火時奧氏化是“不完全”的，只是片狀珠光體轉變成奧氏體，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行正火，將其消除，才能保證球化退火正常進行。 </p> <p> 普通球化退火是將鋼加熱到Ac1以上20～30℃，保溫適當時間，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的溫度進行等溫，等溫時間為其加熱保溫時間的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，并能嚴格地控制退火后的硬度。鋼球經(jīng)過拋光之后會呈現(xiàn)鏡面。</p><div

鋼球感應加熱優(yōu)缺點：感應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，可以使全部淬火過程實現(xiàn)機械化、自動化。鋼球可以用在汽車方向盤里。浙江直銷鋼球值得信賴</p><p
