Embodiment 1

[0032] Example 1: Preparation of titanium steel-carbon steel single-sided composite panel

[0033] Blank making: Select TC4 titanium steel plate and Q345R carbon steel plate to assemble blanks according to the ratio of 1:4. The size of titanium steel plate is 40mm thick × 1500mm wide × 3000mm long, which is used as double plate 1; the size of carbon steel plate is 160mm thick × 1500mm wide × 3000mm long. As the base plate 2; clean the carbon steel plate and titanium steel plate until the metal base is seen; stack the double plate 1 and the base plate 2, send them to the press for compaction, and use 15mm thick carbon steel plates to spot weld around the stacked composite slabs Afterwards, submerged arc welding is used to package and weld, and the end of the welded composite slab blank is drilled to evacuate, and then the hole is closed to obtain a composite slab, such as figure 1 , the thickness of the composite slab is 200mm;

Abstract

The invention discloses a method utilizing a herringbone ripple roller to roll a composite plate strip. The method is characterized in that a composite plate blank consisting of a basal plate and a composited plate is rolled into a herringbone ripple composite plate semi-finished product by a composite roughing mill provided with a herringbone ripple roller, and then, the herringbone ripple composite plate semi-finished product is rolled into a composite plate at a required thickness through a composite finishing mill provided with a flat roller. Herringbone ripples are symmetrically distributed relative to the radial central plane of the roller or symmetrically distributed relative to the axial central plane of the roller, and axial included angles between the herringbone ripples and the roller are 10-80 degrees. According to the invention, the problems that instant shock is produced during transverse ripple rolling and axial force drives the plate strip to shift during longitudinal ripple rolling are solved; and at the same time, the bonding area of the composite plate roughed is increased, so that bonding force between the basal layer and the composited layer is increased, and the compositing strength and compositing efficiency of the composite plate are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of preparation of metal composite strips, and in particular relates to a method for rolling composite strips with herringbone corrugated rolls. Background technique [0002] Metal clad strip refers to a strip that is layered with another metal on one layer of metal to achieve the effect of saving resources and reducing costs without reducing the use effect (anti-corrosion performance, mechanical strength, etc.). Metal composite material technology can give full play to the respective advantages of component materials, realize the optimal allocation of component material resources, save precious metal materials, and achieve performance requirements that cannot be met by a single metal. It is mainly used in anti-corrosion, pressure vessel manufacturing, power construction, Petrochemical, pharmaceutical, light industry, automobile and other industries. Composite methods usually include explosive composite meth...
