hot rolled steel plate

hot rolled steel plate

Hot rolled steel plate is made of continuous casting slab or rolling slab as raw material, heated by stepping furnace, descaled by high pressure water into roughing mill, roughing mill through cutting head, tail, and then into finishing mill, implementation of computer controlled rolling, after the final rolling after laminar cooling (computer controlled cooling rate) and coiler winding, straight coil. The head and tail of straight hair curl are often tongue and fishtail, and the thickness and width are poor. The edge often has defects such as wave shape, hem and tower shape. Its coil weight is heavy, the inner diameter of the steel coil is 760mm.

pressure vessel plate

pressure vessel plate

Pressure vessel plate is a steel plate used to manufacture structural parts of steam boilers, pressure vessels and other pressure vessels. This kind of steel plate is subject to certain air pressure and water pressure, as well as different temperature environments, such as high, medium and low temperature, so the requirements for this kind of steel plate are stricter.

Silicon steel sheet

Silicon steel sheet

Silicon alloy steel containing 1.0 to 4.5% silicon and less than 0.08% carbon is called silicon steel. It has the characteristics of high magnetic permeability, low coercivity, and large resistivity, so the hysteresis loss and eddy current loss are small. Mainly used as magnetic materials in motors, transformers, electrical appliances and electrical instruments. In order to meet the needs of punching and shearing when manufacturing electrical appliances, a certain degree of plasticity is also required. In order to improve the magnetic induction performance and reduce hysteresis loss, the content of harmful impurities is required to be as low as possible, and the plate shape is required to be smooth and the surface quality is good.

Steel grille plate

Steel grille plate

Steel grating is also called steel grating. The grating is a steel product made of flat steel arranged crosswise with horizontal bars at certain intervals and welded into a square grid in the middle. It is mainly used to make ditch covers. , steel structure platform plates, steel ladder treads, etc. The cross bars are generally made of twisted square steel.

FRP grating

FRP grating

Glass fiber reinforced plastic (FRP) grating, also known as FRP grating, is a plate-shaped material with many spaces that is made of glass fiber as a reinforcing material and unsaturated polyester resin as a matrix. It is compounded through special processing. Fiberglass grating can be used as structural materials for floors, trench covers, platforms, ship decks, stairs, planks, etc. in corrosive environments. It has the characteristics of corrosion resistance and flame retardancy, non-magnetic insulation, bright colors, and a variety of styles to choose from.

Alloy steel plate

Alloy steel plate

Alloy steel is mainly composed of materials other than carbon and iron plus alloying elements, such as copper, manganese, aluminum, titanium, rare earth and other materials. Alloy steel has a high strength, and has a good corrosion resistance, high and low temperature resistance, wear resistance and non-magnetic properties, so its life is relatively long. (1) Low carbon: due to the high requirements of toughness, weldability and cold forming performance, its carbon content does not exceed 0.20%; (2) Add alloy elements based on manganese; (3) Adding niobium, titanium or vanadium and other auxiliary elements: a small amount of niobium, titanium or vanadium in the steel to form a fine carbide or carbon nitride, is conducive to obtaining fine ferritic grains and improve the strength and toughness of steel.

corten steel plate

corten steel plate

Weather-resistant structural steel, that is, atmospheric corrosion resistant steel, belongs to low-alloy high-strength structural steel, and is divided into high-weather-resistant structural steel and weather-resistant steel for welding structure according to its main characteristics.
