Abstract: The production process of steel 10Cr21Mnl6NiN wire rod, including composition design, principle of increasing nitrogen, smelting process, rolling and solution process, precipitation of Cr₂N phase is introduced. A 30 t AOD furnace is used for refining, blown nitrogen to increase nitrogen in steel water, and added manganese nitride at the later stage of refining. The surface quality of wire rod is ensured and the problem of central shrinkage is solved by adopting 1 240℃ heating and controlled rolling and cooling in the process. The solution temperature should be controlled at 1 100℃ and cooled quickly after holding for 30 min to prevent the precipitation of Cr₂N phase. The 10Cr21Mnl6NiN stainless steel wire rod with excellent surface quality and performance has been successfully produced.
