Embodiment Construction

[0013] A method for preparing a high-precision tungsten sheet, including heating, rolling, polishing, and leveling a tungsten blank, characterized in that the tungsten blank is coated with graphite milk with a weight concentration of 15% to 20%, and then The billet is uniformly heated for rolling, and then electropolished and pressure-leveled. The uniform heating of the blank adopts a hydrogen nozzle type heating furnace. The furnace body is a box structure. The box body 3 of the furnace body is divided into upper and lower parts by a horizontal gas separator 6; the side wall of the furnace body under the gas separator There is a compressed air inlet pipe 5 on the top, and a hydrogen inlet pipe 4 on the side wall of the furnace body above the gas baffle; uniformly distributed compressed air injection pipes 2 are vertically fixed on the horizontal partition, and the compressed air pipes pass through the heating furnace vertically The upper box plate of the heating furnace is ev...

Abstract

The high precision tungsten plate producing process is especially suitable for producing high precision shielding tungsten plate for CT machine. The production process includes coating the blank tungsten plate with graphite emulsion of 15-20 wt% concentration, rolling after homogeneous heating, electrolytic polishing and pressurizing flattening. The said process is suitable for production of high precision tungsten plate with thickness deviation within 0.01 mm, flatness within 0.005 mm, lower surface roughness and sizes 0.203x146.05x257.05 mm.

Description

technical field [0001] The invention relates to a preparation method of a high-precision tungsten sheet, which relates to a preparation method of a metal tungsten sheet, in particular to a preparation method of a high-precision tungsten sheet used for a medical CT machine. technical background [0002] With the continuous development of industrial technology, the application of tungsten in the form of plates has become a new development direction. For example, a large number of high-precision tungsten sheets are used as shading plates on medical CT machines, which gradually increases the market demand for tungsten sheets. The application of tungsten sheets in the field of medical device production requires improving the processing accuracy of tungsten sheets in order to better meet the needs. The traditional production process can no longer meet the demand because it can only produce rough low-end tungsten plates. Contents of the invention [0003] The purpose of the pre...
