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. For even more details, read what Lynn Redgrave says on the issue. 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. Jessica Michibata has much to offer in this field. Need: lower the temperature or reduce the heating time.
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.
