Steel Surface Descaling Shot Blasting Machine, Steel Dephosphorization And Sand Cleaning Program

       At present, the continuous stainless steel production lines all use the shot blasting mechanical descaling process, which can perform high-performance mechanical descaling on stainless steel strips, which can reduce the acid consumption in the subsequent chemical descaling process, and optimize the use of shot blasting volume , It can obtain high descaling power, and then ensure the uniformity of the surface quality of the processed strip.

       The shot blasting machine throws the shots evenly through the high-speed reverse shot blasting wheel, and uses pressure and centrifugal force to make small steel shots erupt at a high speed (80 m/s) on the upper and lower surfaces of the running strip, and then remove them. The scales on the outer surface of the strip are intended to control the shot peening effect through shot blasting speed and shot size.

       The use of the shot blasting machine can ensure the effective removal of the oxide scale on the surface of the strip. After the hot-rolled strip is annealed, there are many scales attached to the surface of the strip, and the surface after the shot blasting can reach Sa2 ~2.5.

Iron and steel descaling is actually the process of removing the iron oxide, sand and other impurities on the surface of the slab with a shot blasting machine in order to improve the metal defects on the surface of the workpiece rolled by the steel blank before rolling. The editor of Qingdao Wozhou Machinery will talk about the iron and steel dephosphorization cleaning program and related equipment.

Steel dephosphorization cleaning plan:

　　1. According to the previous sales data of the professional manufacturer of Qingdao Wozhou Machinery Shot Blasting Machine, many foundries and other users should use crawler-type shot blasting machines with a relatively high rate of steel descaling.

　　2. This type of shot blasting machine has continuous and uninterrupted descale, descaling, cleaning and strengthening treatments for steel.

　　3. It is suitable for all kinds of cast steel. Users can customize models in Qingdao Wozhou Machinery according to the use of their own factories, and reasonably build a machine suitable for your factory without letting you spend more money.

　　4. The machine is equipped with a powerful dust removal function. The dust removal system is mainly composed of a bag filter, a fan, and a dust removal pipe. The dust removal efficiency of the machine itself can reach more than 95%.

5. The descaling process of castings, forgings and other workpieces makes the surface of the steel blanks appear metallic, and exposes the surface defects of the steel blanks, eliminates the internal stress of the steel blanks, and the surface roughness reaches the Ra12.5 requirements of GB6060.5, which meets the national JB /T8355-96 Sa2.5 level.
