Quality Inspection for Tungsten Wire For Thin Film Deposition - 99.95% Pure Tungsten Sheet Plate For Sale – WINNERS

Product Description

Tungsten plate rolling can be divided into hot rolling, warm rolling and cold rolling. Due to the large deformation resistance of tungsten, ordinary rolls cannot fully meet the requirements of tungsten sheet rolling, and rolls of special materials should be used. During rolling, the rolls should be preheated. According to different rolling conditions, the preheating temperature is 100~350℃. The relative density (ratio of actual density to theoretical density) of the blank can be processed when it is greater than 90%, and the processing performance is good when the blank density is 92-94%. The hot rolling billet temperature is between 1350 and 1500 ℃, and the deformation parameters of the billet are improperly selected, and the billet will be delaminated. The starting temperature of warm rolling is 1200°C, and the thickness of the hot-rolled sheet with a thickness of 8 mm can reach 0.5 mm after warm rolling.
