Our AdvantagesIn the casting process, our company strictly controls the quality:1. Strictly control the raw materials to ensure that the sulfur and phosphorus elements of the raw materials do not exceed the standard;2. Strictly control the temperature of molten iron, do not spill materials, so that the temperature of molten iron is always within the scientific temperature range;3. The shape uses the laminated sand process to ensure that the appearance of the steel ball is smooth and burr-free;4. Strictly control the content when adding elements, implement pre-furnace spectral analysis, and if the pouring sample before the furnace is unqualified, the furnace molten iron is unqualified.5. For the physical and chemical analysis of the formed steel balls, 5 balls are randomly selected per furnace, and 1 steel ball is unqualified, then the furnace is all unqualified, and the furnace is remelted or sold according to the lower grade products;6. Pick, polish and clear the sand of the formed steel ball, pick the unqualified steel ball back to the furnace for re-refining, and clear the sand of the qualified ball small ball mill to improve the service life of the steel ball;7. Further heat treatment and oil quenching of the formed steel balls greatly improve the wear resistance of the product. FAQ1.
