Title:

METHOD FOR ROLLING WIDE NI-FE-CR HEAT-RESISTANT ALLOY THICK PLATE

Document Type and Number:

WIPO Patent Application WO/2022/062013

Kind Code:

A1

Abstract:

Disclosed is a method for rolling a wide Ni-Fe-Cr heat-resistant alloy thick plate. By means of the optimization of heating, rolling and heat treatment processes, a wide Ni-Fe-Cr heat-resistant alloy thick plate having the width of not less than 3350 mm is stably produced using a medium-thickness plate rolling mill, and the diameter of a pipe molded by means of "single longitudinal welding" is increased. The wide heat-resistant alloy thick plate has a high production difficulty and a high additional value, so that very high economic benefits can be created.
