Where is the red rust steel plate applied and its service life cycle

Source:     Time:2021-05-24

Red rust steel plates are widely used. The red rust steel plate is thoroughly manual and power derusting, and the shot blast surface of the latter is rougher. There is no visible grease and dirt on the surface of the steel, and there is no unfixed oxide scale, rust, paint coating and other attachments. Very thorough manual and power rust removal. There should be no visible grease and dirt on the surface of the steel. And there is no weak oxide scale, rust, paint coating and other attachments. The rust removal ratio is more thorough, and the surface of the exposed part of the substrate should have a metallic luster. Flame descaling, represented by the letter "F1", includes the use of a power wire brush to remove the products attached to the surface of the steel after the flame heating operation. There is only one grade: the surface of F1 steel should be free of oxide scale, rust, paint coating and other attachments, and any remaining traces should be only surface discoloration (dark shadows of different colors).

   The red rust steel plate has an excellent price and a long life. The steel plate uses the high-speed operation of mechanical equipment to throw steel shots of a certain size by the centrifugal force of the throwing head, and the thrown steel shots violently collide with the components to achieve the purpose of removing the rust on the surface of the steel. It uses two types of steel shots: cast iron shots and cut steel wire shots. Cast iron shots are iron shots with a particle size of 2 to 3 mm that are formed when molten iron is sprayed and rapidly cooled. The surface is very round. It is relatively cheap but less durable. In the shot blasting process, the iron pellets are crushed and removed as dust after repeated impacts. The cut steel wire shot is made by cutting the steel wire of the waste wire rope into 2mm small sections. Its surface has sharp corners. The rust removal effect is relatively high and it is not easy to be broken. The service life is prolonged, but the price is increased.
