Abstract

The invention relates to a method for manufacturing a large and thick rare precious metal explosion-clad steel plate. The method comprises the following steps of: explosively welding a thin cladding plate with a small area and the thickness of 2 mm to the central zone of a substrate by adopting an opposite-angle detonation manner before explosively welding a cladding plate; and explosively welding the large and thick rare precious metal cladding plate through a strong detonation device by adopting a center detonation manner. The method provided by the invention has the advantages that a rare precious metal and steel clad material with a large area and a thick clad layer can be obtained, the tearing of the periphery of large and thick rare precious metal after explosive welding can be controlled through center detonation, high-cost high explosive can be replaced while the area of an unclad zone of a detonation point is reduced, and the problem that an unclad zone of a center detonation point cannot be subjected to repair welding is solved.

Description

technical field [0001] The invention relates to a technology in the field of manufacturing metal composite materials, in particular to a method for manufacturing a large-thick rare precious metal explosive composite steel plate, which involves multiple explosion welding, central strong detonation, and manufacturing clad layers of large-thick rare precious metal explosive composite steel plate Methods. Background technique [0002] Explosive welding is a metal processing method that uses explosives as the energy source, and under the action of the explosive explosion load, the cladding metal collides with the base metal at high speed and obliquely, and connects them strongly. Rare and precious metals and steel cannot be welded by conventional welding methods, and only the method of explosive welding can be used to produce rare and precious metals and steel composite materials. In the manufacture of large and thick rare metal and steel composite materials, the central detonat...
