Title
(EN) METHOD FOR PREDICTING AND PREVENTING SHRINKAGE CAVITY OF IRON CASTING
(KO) 주철주물의 수축공의 예측 및 방지 방법
Abstract
(EN) A method for predicting and preventing occurrence of shrinkage cavity in an iron casting of any of various shapes or in each part of an iron casting precisely prior to casting. The shape of an iron casting is approximated entirely or partially to a rectangular parallelepiped or a cube, to the sum of the two long sides is divided by the short side to determine a shape coefficient, and occurrence of shrinkage cavity is predicted by judging whether the value exceeds a predetermined value (judgment coefficient) or not. ©KIPO&WIPO 2008
(KO) 여러 가지 형상의 주물이나 주물의 각 부분에 대하여, 주조에 앞서 수축공의 유무를 정확하게 예측하고 방지하는 방법을 제공한다. 주물제품의 형상을 전체적 또는 부분적으로 직육면체 또는 정육면체에 근사하게 만들어, 긴 쪽의 두 변의 합계를 남은 짧은 쪽의 한 변으로 나눈 값인 형상계수를 구하여, 이 값이 한정치(판정계수)를 초과하는지 여부에 따라 수축공의 발생을 예측한다.
