Embodiment Construction

[0020] Below with manufacturing thickness 2.5mm, width 150mm, outer layer is 1Cr13, middle layer is 9Cr18MoV, three layers of equal thickness three-layer bimetallic clad boards are example to further illustrate the manufacturing method of the present invention:

[0021] 1. Ingredients and calculation

[0022] (1) Composite billet size calculation: Calculated according to the total deformation rate of 97%, the thickness of the composite billet is 2.5 / 0.03=83.3 and the thickness is 90mm; the width is 150mm; according to the size of the sand box, the length is 1200mm. The material of the separator is 9Cr18MoV, and the thickness is 2.5mm, so the ratio of the thickness of the composite billet to the total thickness of the separator is 90 / 5=18. The width is 200mm, and the length is 1250mm. The thickness of the outer layer of the composite billet is 30mm, and the thickness of the middle layer is 25mm.

[0023] (2) Calculation of ingredients: the metal weight of the outer layer of t...

Abstract

The invention discloses a method for manufacturing multilayer metal composite slab strips. The method comprises the steps of: injecting respectively different metals or alloys in a liquid state into solidification space separated by division plates to form a complex with the division plates after solidification and obtain metal composite slab strips casting blanks containing equal to and more than two metals or alloys, and then obtaining the finished product metal composite slab bands through a pressure processing method. According to the method provided by the invention, the disadvantages such as large equipment investment, long operation flow, high production cost, and the like existed in the prior art of composite slab strip production technology are overcome, and composite slab strips with strong bonding strength can be manufactured at a low production cost.

Description

technical field [0001] The invention belongs to the technical field of metal composite board preparation and provides a method for manufacturing double (multiple) metal composite boards, which is especially suitable for metal composite board strips used in industries such as cutting tools and pressure vessels. Background technique [0002] Metal composite strip is a new type of composite material that combines two or more different metals or different components of the same metal through various connection technologies, and has the advantages of each layer of metal. Compared with single metal strips, two or more layers of metal composite strips can save the amount of precious alloys on the one hand, and have good comprehensive performance on the other hand. [0003] At present, the production technologies of composite strips that have been reported at home and abroad mainly include: casting composite method, diffusion welding method, pressure brazing method, rolling composit...
