Different particle size and hardness of the products are used in different processes, such as surface strengthening, etc.Before plating workpiece, workpiece adhesive can handle sand blasting scale on the surface of the workpiece and all dirt removed, and the surface it is very important to set up the basis of the schema, but also by changing different particle size of abrasive, to varying degrees of roughness, greatly improve the workpiece and the adhesion strength of the coating, plating materials.Steel shot is used in steel plate pretreatment, generally used for cleaning before coating.
Steel balls are widely used in foundry industry, after the workpiece from the mold, steel balls to remove sand on the surface of the workpiece material.When steel shot with suitable equipment use, because it is durable, must be you are the best abrasive surface cleaning.Steel shot for the manufacturing process, first melting quality of steel pieces, then use high pressure water jet make molten steel to form particle shape, form new heating to purify the pill weight evenly, and then quenching process.Due to tempering iron pills after annealing, the surface color uniform blue, often with tempering cast iron pills pretend to be shot, the service life of the iron pills only 50-400 times, steel shot shot iron rust removing effect seriously reduce, serious harm the interests of the users.
To install steel ball mill according to the reasonable proportion and match ball diameter is right, but it is not necessary when large packed separately, since mill barrel is one of the packed separately also useless, to run or blending.As the production of medium (steel) and also can wear smaller, need time adding ball, such trouble and useless packed separately ball impact the production.Adding ball when installed in accordance with the size and proportion, ball shape and the hardness of small steel shot will have larger to equipment wear and tear.Quenching after the pill was dry and reheating for the furnace body temper to achieve suitable hardness, after tempering treatment of steel shot through mechanical screen is divided into different grades, etc.
Steel shot sort is more, different steel shot, need different raw materials and equipment.Production of steel shot, also have a production line and related equipment, all can buy directly.Need a lot of steel shot, such as casting, forging, machining parts list, after heat-treatment etc on the table, can be sold to related to these places, for example, general manufacturing, shipbuilding, etc., will demand in general how much heavy industry.Advanced casting process equipment: no hydration steel shot USES the international advanced production technology, which USES completely dry resin sand coated on the metal film, completely eliminate the sodium silicate water may cause the casting defects such as porosity, slag inclusion, make the quality of the products have a qualitative leap;And improved iron/carbon ratio, fully meet the requirements for quenching.
