在實際生產中,常需對鑄件缺陷進行分析,其目的是找出產生缺陷的原因,以便采取措施加以防止。對於精密鑄造設計人員來說,了解產品缺陷及產生原因,有助於正確地設計鑄件結構,並結合鑄造生產時的實際條件,恰如其分地擬定技術要求。 精密鑄造件的缺陷很多,其缺陷及產生原因是很複雜的,有時可見到在同一個鑄件上出現多種不同原因引起的缺陷,或同一原因在生產條件不同時會引起多種缺陷。 具有缺陷的精密鑄造件是否被定為廢品,必須按鑄件的用途和要求以及缺陷產生的部位和嚴重程度來決定。一般情況下,有輕微缺陷,可以直接使用;有中等缺陷,可允許修補後使用;有嚴重缺陷,則隻能報廢。 In actual production, it is often necessary to analyze the defects of castings, and the purpose is to find out the causes of defects so as to take measures to prevent them. For the precision casting designers, understanding the defects and causes of the product will help to design the casting structure correctly and combine the actual conditions of the casting production to formulate the technical requirements properly. There are many defects in the precision casting parts. The defects and causes are very complicated. Sometimes, there are many defects caused by various reasons on the same casting, or the same reason can cause a variety of defects at the same time. Whether the defective castings are classified as scrap must be determined according to the purpose and requirements of the castings and the locations and severity of the defects. Under normal circumstances, there are minor defects that can be used directly; if there are moderate defects, they can be used after repair; if there are serious defects, they can only be scrapped.
