球墨铸铁炉前检验是其生产过程中不可缺少的一环 ,它直接关系到球墨铸铁件的质量。及时、准确判断铁液球化情况 ,可以迅速采取措施控制球墨铸铁的质量。炉前误判将大量报废铸件 ,造成严重的经济损失 ,因此 ,炉前及时、准确判断球化情况比炉后检验重要得多。一、炉前检验的方法? Ductile iron furnace test is an indispensable part of its production process, which is directly related to the quality of ductile iron parts. Timely and accurately determine the status of iron ball, you can quickly take measures to control the quality of ductile iron. Misjudgment of the furnace will scrap a large number of castings, causing serious economic losses, therefore, in front of the furnace, accurately determine the situation is more important than the ball after the furnace test. First, before the test method?
