Defects in Continuous Cast Steels Continuous casting (CC) is the process which converts liquid steel into a solid product mainly in the form of slab (either thick or thin), bloom or billets. Blowholes are spherical or elongated cavities present in the casting on the surface or inside the casting. A condition existing in a casting caused by the trapping of gas in the molten metal or by mold gases evolved during the pouring of the casting. Dental casting Introducing various metal casting defects with many pictures by Dandong Foundry in China. These are the common sand casting defects on the surface and inside of cast iron and cast steel parts. It is one of progressive steel making technologies which produces a cast product of a … The sizes given in Table 2 assume maximum applied tensile stress levels of half yield strength magnitude, acting normal to the plane
They are broken down into five main categories: gas porosity, shrinkage defects, mould material defects, pouring metal defects, and metallurgical defects. Casting Defects - Sand Mold, Metal Casting. defects and (b) embedded penny-shaped defects in two nickel base forgings and a superalloy casting are determined assuming a critical to final defect size ratio of five. 1. Blowhole and Pinhole This is a kind of cavities defect, which is also divided into pinhole and subsurface blowhole. The defects in this category can be classified into blowholes and pinhole porosity.
