Sedation killed steel plate is made of ordinary steel hot-rolled carbon steel. Killed steel is fully deoxidized steel, molten steel before casting a full deoxygenation 45mn steel plate ferromanganese, ferrosilicon and aluminum, steel liquid oxygen is low (typically 0.002-0.003%), liquid steel in ingot mold relatively calm, no boiling, killed steel hence the name. Under normal operating conditions, no air bubbles killed steel, dense homogeneous; the oxygen content is low, less oxide inclusions in steel, high purity, small cold brittleness and aging tendencies; and alloy steel plate, steel segregation relatively calm Small q460d alloy steel plate, alloy steel plate 37crni3 more uniform performance and higher quality. Disadvantage of killed steel is concentrated shrinkage, 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. The main purpose of producing a large quantity of boiling steel stamping parts, construction and engineering structures and some of the less important of the machine structure and parts. (2) grades, chemical composition and mechanical properties of materials in line with the provisions of GB700-79 (88) (ordinary carbon steel structural conditions) in boiling steel. See the (steel) and other components. (3) hot-rolled steel plate steel Dimensions thickness 4.5-200mm.
