Abstract

The invention relates to a composite plate and a manufacturing method, in particular to a manufacturing method for a high-magnetic permeability thick steel aluminum-steel copper composite for a linear motor. A composite induction plate is formed by compounding a steel plate and an aluminum plate or compounding the steel plate and a copper plate. The steel plate has a thickness of 10 to 100mm and yield strength of 345 to 1,000Mpa. The aluminum plate or the copper plate is 3 to 30mm thick. A low-carbon weak-strength steel and aluminum/copper composite material also can be produced. Production cost is low, production efficiency is high, and a product has a uniform thickness and high quality.

Description

technical field [0001] The invention relates to a composite induction plate, especially a high-permeability and large-thickness steel-aluminum or steel-copper composite induction plate, which is used as a secondary composite induction plate for a linear motor of a maglev train or a wheel-rail train and a manufacturing method thereof. Background technique [0002] Steel-aluminum composite panels have been widely used in equipment and facilities such as civilian cookers, radiators, and large air condensers for refrigeration in power stations. The demand is huge and is on the rise. For a long time, steel-aluminum composite products have mainly relied on imports. Through cooperation with customers, Angang has developed and trial-produced cold-rolled and hot-rolled steel strip substrates for composite use—that is, low-carbon low-strength hot-rolled and cold-rolled steel strips, with a thickness of 0.2-3mm, C≤0.17, Mn≤0.60 , Si≤0.30. Chinese patent 91106921 discloses a steel gra...
