Embodiment 1

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

[0033] Billet making: Select TC3 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 of rolling composite plate and strip by a slanting corrugating roll. The method is characterized by comprising the following steps that a composite slab which is composed of a basal plate and a multilayer plate is rolled by a composite roughing mill with the slanting corrugating roll to prepare a semi-finished slanting corrugated composite plate, and then the semi-finished slanting corrugated composite plate is rolled by a composite finishing mill with a flat roll until the needed thickness to obtain a composite plate, wherein an axial included angle between slanting corrugation and the roll is 10-80 degrees. According to the method, the problems that instant impact is generated during rolling of a transverse corrugating roll, and the plate and strip are in deviation due to the axial force during rolling of a longitudinal corrugating roll are solved, and meanwhile, the combination area of the composite plates after being roughly milled is increased, so that the binding force between the basal plate and the multilayer plate is improved, and the composite strength and the composite 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 oblique 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 method a...
