在 Mo—0.5Ti 合金板材生产中,板面有时出现亮条,影响产品质量。出现板面亮条的原因,目前还不十分清楚。本文以我厂几年来积累的钼合金板材生产经验为基础,从金相研究入手,探讨了“表面亮条”的本质。一、板面亮条的出现生产 Mo—0.5Ti 合金板材,经过如下工序,即高纯钼条和纯钛片组成电极,由真空自耗电弧炉焙炼成园锭→表面车光后,在焕气保护下加热至1450～1600℃挤压成棒→煤气保护下再结晶退火之后,表面喷砂→煤气保护下加热至1350℃～1450℃锻造成板坯→
In Mo-0.5Ti alloy sheet production, the bright surface sometimes appear, affecting product quality. There are bright reasons for the board, it is not yet clear. Based on the experience gained in the production of molybdenum alloy sheet over the past few years, this article starts with the study of metallography and explores the essence of “bright surface”. First, the bright appearance of the plate production Mo-0.5Ti alloy plate, after the following process, that is, high-purity molybdenum and titanium electrode composition from the vacuum consumable electric arc furnace into the ingot → surface light car, Heated to 1450 ~ 1600 ℃ under the rejuvenation protection Extruded rods → recrystallization annealing under gas protection, surface blasting → gas protection heated to 1350 ℃ ~ 1450 ℃ forging into a slab →
