Classification steel (including steel) are: heavy steel plate processing 1, according to the thickness of the classification: (1) sheet (2) in the plate (3) slabs (4) special plate 2, according to the production method of classification: (1) heat rolled steel plate (2) cold-rolled steel plate 3, characterized by surface classification: (1) galvanized sheet (galvanized plate, galvanized sheet) (2) tin plate (3) composite plate (4) color coated steel 4 , By Application: (1) a bridge plate (2) boiler plate (3) shipbuilding steel plate (4) armor plate (5) automotive steel (6) Roof plate (7) Structural Steel (8) electrical steel (silicon) ( 9) of the spring plate (10) Other sedative killed steel sheet steel hot-rolled steel sheet is made of ordinary carbon steel. Killed steel is fully deoxidized steel, manganese steel manufacturers, steel liquid before pouring a full deoxygenation with ferromanganese, ferrosilicon and aluminum, Hefei steel manufacturers, steel liquid oxygen is low (typically 0.002-0.003%), steel It was relatively calm in the ingot mold, no boiling, killed steel hence the name. Under normal operating conditions, no air bubbles killed steel, dense homogeneous; the low oxygen content, color steel manufacturers, steel oxide inclusions less, high purity, small cold brittleness and aging tendencies; meanwhile, killed steel segregation is small, the performance of more uniform, higher quality. Disadvantage of killed steel is concentrated shrinkage, color steel manufacturers, finished product rate, higher prices. Therefore, the steel is mainly used for higher member calm, welded structures and other requirements of the strength members are subjected to impact at low temperatures.
