MANUFACTURING METHOD FOR TWO-LAYER HOT-ROLLED STEEL PLATE Russian patent published in 2014 - IPC B23K20/04 B23K25/00

Abstract RU 2534888 C1

FIELD: metallurgy.

SUBSTANCE: bimetallic workpiece is produced by electroslag facing on workpiece of primary layer of consumable electrodes from corrosion-resistant steel. Then bimetallic workpiece is rolled on steel plates. Before facing on the whole length of primary layer workpiece, in under-electrodes space cover plates are welded, and in inter-electrodes space recesses are grinded out. Cover plates are made from steel close by its chemical composition to steel of primary layer or steel of consumable electrodes. Cover plate section is a plane described by zigzag line or arc or their combination.

EFFECT: uniformity of hot-rolled bimetallic plates cladding layer thickness, high strength and integrity of layers adhesion, as well cladding layer corrosive resistance.
