Abstract
The utility model relates to a metal strip, in particular relates to single-sided asymmetric section steel-based composite strip steel, and solves the problems of high processing cost and the like of a double-sided stainless steel composite strip. The single-sided asymmetric section steel-based composite strip steel is structurally formed by compounding a carbon steel base layer and a corrosion-resistant layer arranged on one surface of the carbon steel base layer; a stainless steel layer or titanium layer or titanium alloy layer is used as the corrosion-resistant layer; and the thickness of the carbon steel base layer is 1.88-26 mm, the thickness of the corrosion-resistant layer is 0.13-4.0 mm, the total thickness is 2.01-30 mm, the length is 90-500 mm, and the width is 0.5-2.5 mm. Due to use of the one-sided composite layer material which is equivalent to double-sided composite material, the material is greatly saved, the cost is lowered, and the energy consumption is reduced; and moreover, the strip is long, the shear-resisting strength of the interface is higher than the strength of corresponding base layer, and a thick strip can be directly applied to the building industry and is particularly suitable for processing a pipe of a building structure and processing a corrosion-resistant pressure container.
Description
Technical field
The utility model relates to a kind of sheet metal strip, is specially the asymmetric base steel composite strip steel of a kind of single face.
Background technique
Domestic Composite Steel sheet material commonly used only has the compound middle plate of single face and a spot of two-sided composite strip steel at present, and the size extreme length of single face Composite Steel sheet material is about 40M, can't satisfy the affected requirement of continuous welded tube or heavy construction structure; Two-sided composite steel band by carbon steel as the basic unit of centre, compound the processing of stainless steel lining of both sides; In actual use; General of the container that this steel band is made need simultaneously carry out the stainless steel processing and get final product; Two-sided so compound steel band is superfluous for a considerable amount of industries and client's sensory function, and price is higher, also is a kind of wasting of resources.The general monovolume of two-sided composite steel band is about 100 meters, thinks in traditional thinking that the complex radical material is different with the chemical composition of top layer metal, and physics such as high temperature deformation drag, linear expansion coefficient and mechanical property have certain difference.When the transverse section geometric center lines of rolled piece in roll gap up and down or left and right sides structure when asymmetric; Then bend and warping phenomenon; Cause to get into down a time roll gap; Especially on the tandem rolling unit, serious warpage tends to cause pernicious production accident and equipment accident to take place, and is the asymmetric composite strip steel of base steel single face stainless steel or titanium, total thickness 2.0～30 ㎜, width >=500 ㎜, length >=100m so still lack multiple layer so far on the market.Although and the compound middle plate of single face has adopted metal-based layer to add the compound structure of individual layer stainless steel; But because its processing is not to adopt rolling processing; The thinking of the processing difficulties that also can not cause in the face of above-mentioned dissymmetrical structure, and in fact this compound in its total thickness of plate and material also determined it can not process coiled strip.
Summary of the invention
The utility model provides a kind of single face asymmetric base steel composite strip steel in order to solve problems such as having two-sided stainless steel compound belt material cost height now.
The utility model is realized by following technological scheme, the asymmetric base steel composite strip steel of a kind of single face, and structure is by carbon steel base layer and compound composition of corrosion-resistant coating that is positioned at a face of carbon steel base layer, and described corrosion-resistant coating is stainless steel lining or titanium layer or titanium alloy layer; Carbon steel base layer thickness is 1.88-26mm, and corrosion-resistant coating thickness is 0.13-4.0mm, and total thickness is 2.01-30mm, and length is 90-500m, and width is 0.5-2.5m.
Compared with prior art, the asymmetric base steel composite strip steel of the described single face of the utility model has only used the structure of a basic unit and a composite bed, and the band of formation belongs to dissymmetrical structure; Overcome the narrow limitation of existing technology thinking; No low-melting material in its composite strip steel, good heat resistance, interfacial bonding strength is high; 1000 ℃ not stratified, the processing of harshness such as can bear shearing, bending, draw and the quality that remains intact.Fill up the blank and not enough of existing composite material, complex radical owing to only used the composite material of one side, is equivalent to the two-sided compound wide variety of materials of having practiced thrift than≤0.15 like this, has reduced cost, energy efficient.Band is long, the interface shearing-resistance shearing stress be higher than corresponding foundation base intension and thick specification can directly be used for construction industry, be specially adapted to building structure tubulation processing and anti-corrosion pressurized container processing and fabricating.Can keep stainless for a long time without protection by paints and lacquers, thereby realize purpose energy-efficient, that practice thrift precious metal.
