background-color: transparent; color: rgb(68, 68, 68); text-decoration-line: none; outline: none; transition: all 0.3s ease 0s;">灰铁铸件</a>表面光洁度就要先了解哪些因素可以直接影响铸件光洁度的高低，①铸造模具的好坏及模具型面是否光滑，铸造模具型面光洁度越高铸造出来的铸件表面光洁度也就越高。②造型耐火涂料质量的好坏或耐火涂料涂刷厚度也会影响铸件表面光洁度，耐火涂料质量越好，涂刷厚度合理铸造出来的铸件表面光洁度越好。③造型时选用的型砂会对铸件表面光洁度有直接的影响，型砂越细越好，造型后的型腔硬度越高越好。</span></p><p style="box-sizing: border-box;
