好专业,冶金专业英语词汇很多,果断放弃.高分不好拿,,我试试看,看你认真的
the material must be thrown into the refining furnace at the Aluminum ingot and foundry returns of 7:3.after each time being thrown,the material must be refined whlie the temperature of the molten aluminum must be maintained over 700 degrees in the refining furnace.
When people change shifts,they must strictly control the holding furnace temperature and the molten aluminum retention of the crucible and close the refining furnace valve while they clean the workplace.The molten aluminum temperature in the holding furnace should be maintained between 640 degrees and 680 degrees.The molten aluminum retention of the crucible in the holding furnace must be below the range of 40mm or 50mm from the crucible mouth.你看看,翻得不好,见谅,毕竟不熟悉的题材.有什么奖励,是美妞的话,就亲一个,哈哈,玩笑话,希望对你有用.
