https://new.redtea.kr/pb/pb.php?id=fun&no=37636&divpage=8&ss=on&sc=on&keyword=호미 유게 이 글 가장 마지막 영상 보고 궁금해서 올려봅니다. 이 영상에 보면 대장간에서 망치질만 망치질하는 기계가 하고 나머지를 다 수공업으로 하네요. 주조나 선반 뿐만 아니라 저렇게 두드리는 단조법으로도 항공기나 자동차 부품을 찍어내는 걸고 알고 있는데 이런 호미같은 공구들은 공장에서 만들면 품질이 나쁜가요? 아니면 기계로 자동화 할 정도의 경제성이 없어서 안 만드는 건가요? 그리고 또다른 궁금증 ㅡㅡㅋ 강철은 결국 철과 탄소합금인데 저렇게 불에 달궈서 모양을 변형해도 합금성질이 변하지 않는 건가요? 탄소가 날아가거나 그럴 것 같아서요. 그럼 금속을 녹였다가 굳혀도 여전히 강철합금인가요?
