[求助] 求大神翻译一小段英语片段急急急急急急!!!

The addition of magnesia may cause the formation of spinel and CA6, which accompanied by volume expansion
during the use of ladle, so that it is essential to control the expansion.
       Otherwise, difference in expansion between the hot face and interface may lead to spalling like the ASM (B),
decreasing life time of steel ladle. One of effective methods to control expansion is addition of microsilica.
Nonetheless, it is important to find optimal and proper content microsilica in castables according to the operational
condition because the addition of microsilica may accelerate spinel formation as well as sintering shrinkage.

使用钢水包时,添加氧化镁可能导致生成尖晶石和CA6,同时也会引起体积膨胀,因此控制膨胀是必须要考虑的.否则,加热面和交界面上膨胀量的不同会导致如同ASM (B)中的散裂,从而降低钢水包的寿命.控制膨胀的一个有效方法就是添加硅粉.因此,根据操作条件的要求,找到应往浇注材料中添加的最合适的硅粉量是很重要的, 因为增加硅粉既会加快尖晶石的形成,也会加快烧结收缩.
