一概述手表制造厂,对钢质传动轴类、上条拨针、螺钉等机芯零件必须进行淬火、回火热处理,以使它们具备规定的韧硬性,保持一定的光亮度,不氧化、不脱碳.为此,零件必须在一定的保护气体中进行热处理.手表厂一般采用甲醇裂化炉,以化学纯甲醇制取CO保护气体,达到预期的目的.为了减少消耗,降低成本,现采用工业甲醇代替化学纯甲醇进行工艺革新. An overview of the watch manufacturer, the steel shaft, winding dial, screws and other parts must be quenched and tempered, tempering heat treatment so that they have the required toughness, to maintain a certain degree of brightness, not oxidation, not Decarburization.To this end, the part must be in a certain protective gas heat treatment.Watch factory generally use methanol cracking furnace, chemical pure methanol to obtain CO shielding gas, to achieve the desired purpose.In order to reduce consumption and reduce costs, the use of industrial Methanol instead of chemical pure methanol for process innovation.
