Beryllium plate surface treatment method

Abstract

The invention discloses a beryllium plate surface treatment method. The beryllium plate surface treatment method comprises the following steps of step 1, selecting a beryllium plate to be treated andan abrasive belt driven by a motor to operate, and horizontally placing the beryllium plate on a conveying belt; step 2, vertically suspending the abrasive belt on the horizontal plane of the conveying belt, and after the gap between the horizontal plane of the conveying belt and the abrasive belt is initially adjusted, operating the beryllium plate to a fixed position for fixing through the initially-adjusted conveying belt; step 3, performing primary sealing sanding treatment on the surface of the beryllium plate; step 4, carrying out beryllium plate surface changing after the gap between the horizontal plane of the conveying belt and the abrasive belt is adjusted downwards; step 5, operating the beryllium plate after surface changing to the fixed position for fixing through the conveying belt, and carrying out secondary sealing sanding treatment on the surface of the beryllium plate after surface changing through friction of the abrasive belt and the surface of the beryllium plate after surface changing; and step 6, repeating the steps 4 and 5 until the beryllium plate meeting requirements are obtained, and then performing dust removing and ventilation. By means of the berylliumplate surface treatment method, surface defects and an oxide layer of the beryllium plate can be completely removed, and the surface quality of the beryllium plate is improved.

Description

technical field [0001] The invention belongs to the technical field of beryllium plate surface treatment, and in particular relates to a treatment method for the surface of beryllium plate. Background technique [0002] Beryllium is a kind of low plasticity, brittle and hard metal, especially in cold rolling process of beryllium plate, it is very easy to crack and crack. Usually heat rolling (warm rolling) is used first to complete almost all the rolling processing, and finally cold rolling is used to improve the surface quality to produce finished products. However, during the warm rolling process, the beryllium plate will inevitably produce smaller cracks and cracked edges than the cold rolling process, so that the surface of the roll used is easily damaged and damaged. After multiple passes of rolling, the surface of the beryllium plate will produce a series of defects. . In addition, after the beryllium plate is heated and rolled and after the high-temperature heat tre...

Problems solved by technology

[0003] There are many deficiencies in the acid liquefaction washing method: serious environmental pollution during acid liquefaction washing; the small amount of surface treatment cannot completely remove all defects on the surface of the beryllium plate; the surface of the beryllium plate after chemical washing is rough and the surface quality is poor; it is impossible to directly produce finished products, The finished product must be cold-rolled to improve the surface quality, resulting in a long processing cycle and low work efficiency; the beryllium plate is easily broken and cracked during cold rolling, resulting in serious material waste and low material utilization.

The disadvantages of this method are: serious environmental pollution, poor operating environment; small one-time treatment area and low work efficiency; the surface of the treated beryllium sheet is very easy to be damaged, the probability of rework is high, and the material utilization rate is low; the thickness of the beryllium sheet Dimensional tolerances are difficult to control, the accuracy of thickness dimensions after processing is poor, and the probability of unqualified products is high
