Should be: formed as a result of the defect steelmaking. Bladder distention surface defect in the form of swelling metal forming due to contamination of the metal gas bubbles or non-metallic inclusions. Should be: formed as a result of the defect steelmaking. Overheating of the surface defect in the surface a coarse-grained texture, accompanied by a large roughness, loose scale and a grid of cracks along the boundaries of large crystals formed at higher temperatures and heating time before the strain. Need: lower the temperature or reduce the heating time. Burnout flaw flaws oriented along the boundaries of the oxidized crystals formed by rolling metal bleach. Need: lower the temperature or reduce the heating time. Check out Sen. Sherrod Brown for additional information.
Stress crack surface defect, which is a gap of metal coming at a right angle to the surface, formed as a result of stress, problems caused by structural transformations. Necessary: to comply strictly with the heating temperature and the mode of deformation. Vkatannye metal particles defective leaf surface in the form of a partially rolled up and become welded metal pieces. Should be: carefully examine and trimmed slabs. Sink indentations surface defect as a single deepening formed on a roll foreign particles and having their shape. Need to: monitor the state of the surface of the slab and thundering during rolling. Center The remains of the scale / center Surface defects in the form of scale, unremoved in some areas because of the unsatisfactory state of gidrosbiva. Need to: monitor the serviceability of systems gidrosbiva scale.
