Manufacturing method of super-long plate based on explosive welding and obtained super-long plate

Abstract

The invention discloses a manufacturing method of a super-long plate based on explosive welding and the obtained super-long plate, and belongs to the field of material processing. According to the manufacturing method of the super-long plate based on explosive welding, a flying plate and a base plate are manufactured through base metal alloy, then the flying plate and the base plate are compounded into a composite plate pre-finished product through an explosive welding method, and then deformation machining and recrystallization treatment are conducted on the composite pre-finished product, so that a composite plate becomes a seamless integrated large-size plate; and the operations above are repeated until a super-long composite plate with the preset length is obtained. On the basis of explosive welding, a welding interface formed in the composite plate manufacturing process is eliminated through large deformation and recrystallization annealing treatment, and the bonding strength can reach that of base metal; and the super-long plate meeting the requirement can be obtained through deformation processing treatment, the deformation capacity of the plate is recovered through recrystallization treatment, structure grains are refined, the performance is improved, and the plate can be further used as a high-performance base plate.

Description

technical field [0001] The invention belongs to the field of material processing, in particular to a method for manufacturing an ultra-long plate based on explosive welding and the obtained ultra-long plate. Background technique [0002] In the development of today's society, due to the simple shape of the plate, the amount used in the development of the national economy is large. The plate products produced by conventional manufacturing technology have a flat shape, a large aspect ratio and a large specific surface area, so the rolling pressure in production is very high. , can reach millions to tens of millions of newtons, the rolling mill equipment is complex and huge, and it becomes very difficult and complicated to produce large-tonnage super-long plates and control the surface quality. The traditional single large-tonnage plate ingot is difficult to process in production, the efficiency is low, and the equipment requirements are high, the product performance level is l...

[0002] In the development of today's society, due to the simple shape of the plate, the amount used in the development of the national economy is large. The plate products produced by conventional manufacturing technology have a flat shape, a large aspect ratio and a large specific surface area, so the rolling pressure in production is very high. , up to millions to tens of millions of newtons, the rolling mill equipment is complex and huge, and it becomes very difficult and complicated to produce large-tonnage super-long plates and control the surface quality

The traditional single large tonnage plate ingot is difficult to process in production, the efficiency is low, and the equipment requirements are high, the product performance level is low, and the quality control is difficult to guarantee accurately
