style="text-indent:25px">球墨鑄鐵件與灰鑄鐵件的區(qū)別？怎樣鑒別看這里！球墨鑄鐵件和灰鑄鐵件應(yīng)用的范圍非常普遍，一直是大家比較常用的鑄鐵件，那么，怎樣鑒別鑄鐵件是球墨鑄鐵件還是灰鑄鐵件呢？球墨鑄鐵件和灰鑄鐵件的鑒別有以下幾種方法。一、從敲擊的端口觀察，球墨鑄鐵件的晶粒細(xì)小，呈黑灰色，而灰鑄鐵件的的晶粒比較粗大，呈灰白色。二、從加工的表面看，球墨鑄鐵件比灰鑄鐵件更加光亮。三、從敲打聲音判斷，敲擊球墨鑄鐵件的聲音清脆，有回音且回音長，二灰鑄鐵件沒有回應(yīng)，聲音比較悶。以上就是小編跟大家分享的如何區(qū)別球墨鑄鐵件和灰鑄鐵件的方法。臺州球鐵鑄件供貨公司</p></p><br
