Study of Hot-rolling Process of Pure Molybdenum Plates with Large Single Weight AITranslate
Abstract AITranslate
Based on different process programs,the effects of rolling temperature,pass deformation rate and rolling rate on the structure and rolling yield of the pure molybdenum plate with a large single weight and a size of 72 mm×450 mm×320 mm were studied during cogging rolling.And the causes of the microcrack in molybdenum plates were analyzed.The results showed that there are microcracks caused in rolled pieces during cogging rolling,when the cogging temperature is lower than 1 350 ℃,average pass deformation rate above 21.5% and rolling rate lower than 48 m/min.And these microcracks extend with decreased heating temperature during later rolling.The optimum cogging temperature,average pass deformation rate and rolling rate should be controlled in the ranges of 1 450～1 500 ℃,20%～22%,48～53 m/min,respectively.
