Abstract

A method of a lock catch type vacuum rolling metal composite plate comprises the following steps that penetrated grooves are machined in the end faces of the two ends, vertical to the rolling direction, of a base plate respectively, and correspondingly, L-shaped embedding strips are welded to corresponding positions at the two ends of a shroud plate respectively; greasy dirt on the surface to be compounded is cleaned; the L-shaped embedding strips at the two ends of the shroud plate slide into the grooves in the two ends of the base plate to enable a composite slab formed by the shroud plate and the base plate to be in an embedded state. Sealing plates are connected to the periphery of the composite slab in a welded mode to enable composite space to be sealed; holes are formed in the sealing plates, air between the shroud plate and the base plate is extracted through the holes, and the holes are blocked after vacuum pumping is carried out; the composite slab is heated to 950-1300 DEG C to be rolled until the composite slab reaches a needed thickness to form the metal composite plate; edge cutting is carried out on the rolled metal composite plate, the sealing plates are removed, and rolling of the composite plate is completed. According to the method, mutual movement of adjacent slabs in the rolling direction and the slab thickness direction can be effectively constrained, rolling stability is improved, and meanwhile composite strength of the metal composite plate is greatly increased.

Description

technical field

[0001] The invention relates to a rolling method of a metal composite plate, in particular to a lock-type vacuum rolling method for a metal composite plate. Background technique

[0002] Metal composite panels are composited by two or more metal panels with different properties through special preparation methods. Compared with single metal components, metal composite panels after rational design and combination combine the respective advantages of metal components, and can obtain mechanical, physical and chemical properties that single metals do not have. In recent decades, the development, production and application of metal composite panels have attracted more and more attention. So far, this composite material has been widely used in aerospace, petroleum, chemical industry, metallurgy, machinery, automobile, ship, construction and other fields.

[0003] The preparation methods of metal clad plates mainly include: explosive cladding method, casting metho...
