blazed iron 中文意思是什麼
-
The speed became fast at the temperature 1050. the reaction could carry completely when billets was kept in vacuum tube for 3 hours " at 1050 temperature, under the striking of great quantity of heat when the molten iron poured into the mold, the reaction was blazed rapidly and continued at a high speed. the diffusible speed of v and c was very fast because the billet was heated over 1300 in a moment, so the reaction ca n complete in a few minutes
( 5 )碳化反應v + c vc在900左右開始發生,此時是固相反應,反應速度較慢,反應不能進行完全,隨溫度升高,該碳化反應的速度加快,在1050保溫3小時可以進行完全,在鑄造燒結時在過熱鐵水的巨大熱流密度沖擊下, v + c vc立即被激發,並以很快的速度進行,由於坯塊被加熱到1300以上,此時c和v擴散速度很快,因此鑄造澆注后的幾四川大學碩士學位論文分鐘內反應可以進行完全。
