Abstract

The invention provides a production method of rolled laminated metal composite roll, in which laminated metal composite blank is in vacuum state before assembling and rolling and in non-vacuum state in the hot rolling process. The method is characterized in that the inner end of an aluminum hollow pipe segment enters a reserved rolling extension space in the composite blank, the other end is connected with a vacuum pump; and the composite blank is evacuated through the vacuum pump and the pipe segment. The method can ensure the high vacuum degree in the composite blank before rolling, and can keep the internal junction surface of the composite blank clean and prevent oxidation. The method can ensure that air is discharged in time, thereby radically solving the problems of the prior art caused by the difficulty in discharging air in the composite blank, such as surface damages of the composite rolls or even damages to rolling equipment. The laminated metal composite material roll prepared by the method has the advantages of high strength, good mechanical processing performance, high corrosion resistance, high surface decorativeness, high quality and low production cost.

Description

technical field [0001] The invention relates to a method for rolling a laminated metal composite plate, in particular to a method for vacuum forming blanks-non-vacuum rolling laminated metal composite coils, which belongs to the technical field of steel rolling. Background technique [0002] Hot-rolled laminated metal composite coil refers to the metal clad layer such as stainless steel plate and the metal base layer such as carbon steel plate welded to form a composite billet, and then the composite billet is hot-rolled to obtain a metal composite coil. The basic principle is to bond two metal layers with clean surfaces to each other and weld them along the periphery to make a composite slab, and make the composite slab under a certain temperature and rolling pressure to realize the metallurgy of the base layer and the clad layer metal. In combination, its production process is generally: billet assembly-rolling-post-treatment. [0003] The hot-rolled laminated metal compo...
