The weight of one product is up to 700 kg. Product dimensions no more than 1350x2200x7400 mm. This method of working with metal products refers to the cold processing method, in which the metal surface is "bombarded" with small particles (shot), accelerated by a stream of compressed air. Steel chipped shot (European manufacturers), obtained by crushing cast steel shot, is divided into three types: GP chipped shot with a hardness of 45-52 HRc, GL chipped shot with a hardness of 53-57 HRc and GH chipped shot with a hardness of more than 64 HRc. This variety allows you to optimally select and purchase shot for blasting a wide variety of surfaces. Depending on the application, the shot is selected with a certain diameter and quality. The use of shot blasting of metal makes it possible to effectively remove scale from the surface of the material, perform a global cleaning of rusty deposits, and completely remove corrosive foci from the metal surface. Shot-blasting of the metal surface allows to obtain a well-cleaned surface with a uniform roughness, which contributes to the best adhesion of anticorrosive paints and varnishes. The use of shot blasting of metal helps to extend the service life of structures and improve the technical qualities of metal products. In the process of impacts of the shot on the metal surface, its partial deformation occurs, due to which a surface layer with a high degree of internal stress is formed. This state of the metal increases the anti-corrosion properties of the product and increases resistance to other types of damage. Depending on the initial state of the metal during shot blasting, the following degrees of purification can be distinguished: Sa 1 Легкая дробеструйная очистка. Неплотно сидящие куски окалины, ржавчины и легко отделимые посторонние частицы должны быть удалены. Sa 2 Тщательная дробеструйная очистка. Почти вся окалина и ржавчина и почти все посторонние частицы должны быть удалены. Затем поверхность очищается пылесосом или чистым сухим воздухом под давлением или же чистой щеткой. Поверхность должна иметь сероватый цвет. Sa 21/2 (2,5) Весьма тщательная дробеструйная очистка. Окалина, ржавчина и посторонние частицы должны быть удалены так, чтобы остатки были лишь в виде слабых затенений или полос на поверхности. Затем поверхность очищается пылесосом или чистым сухим воздухом под давлением или же чистой щеткой. Sa 3 Blast cleaning until a clean metal surface is obtained. Scale, rust and all foreign particles must be removed. Then the surface is cleaned with a vacuum cleaner or clean dry air under pressure or a clean brush. The surface should have a uniform metallic color. For shot blasting of metal, the enterprise uses imported equipment of the Сlemco brand. The cost of metal blasting is calculated upon request, which you can send to the general email. mail: mail @ npc-53. ru For a quick calculation, it is necessary to indicate the quantity, weight and dimensions of the products, and, if possible, attach a drawing of the product itself.
