The first batch of nickel based alloy sheets successfully rolled on the aerospace wide titanium alloy sheet production line

Recently, the first batch of 339 nickel based alloy sheets, totaling 43.7 tons, successfully rolled on the aerospace wide titanium alloy sheet production line of Baotai Group, laying a solid foundation for the company's mass production of high-temperature alloy sheets.

The rolling of nickel based alloy thin plates this time faces difficulties such as zero production experience, high requirements for thickness accuracy, appearance quality, and plate shape. At the same time, nickel based alloys have characteristics such as high temperature deformation resistance, narrow hot working window, and poor thermoplastic properties. This is not only a test of the equipment capacity of the newly completed 1850mm hot rolling production line, but also a test of the combat ability of the sheet metal factory team.

The sheet metal factory attaches great importance to this task and promptly organizes equipment, process, skilled craftsmen, and technical personnel from the manufacturer to form a research group, conduct multiple rounds of scheme discussions, boldly innovate processes, calculate rolling data, optimize rolling processes, and strictly control production processes. During the rolling process, the project team members of the production line worked together and closely cooperated, carefully sorting out the rolling points and promptly solving on-site problems; Front line workers carefully adjust equipment and strictly control parameters such as rolling pass pressure and rolling speed. With the joint efforts of all personnel, the first batch of nickel based alloy thin plates with a width of 1000-1400 millimeters were produced, with small thickness differences, high surface quality, and excellent plate shape, fully meeting customer requirements.
