(1).Raw material: Round steel ,the raw material of forged balls ,are totally ordered from our national large -scale steel mills. We can also provide special processing as per special requirements of different grinding balls
Materials.
(2).Scientific Proportioning :Rational chemical composition is gradually optimized and formed by our technical staff after continuous tests. It is unique .The best configuration of various alloying elements can combine the ball′s hardness and toughness’ at their best.
(3).Electric furnace smelting: All cast steel balls are produced by intermediate frequency electric furnace .The purity and stability of materials are effectively ensured after uniform temperatures conditioning and twice hot metal purificati0n.
(4).Assay before furnace :Temperature control is an important and complex process during cast steel ball production. Different tapping temperature and heat temperature are sensitively reflected in the quality of the products. It is requested to master the proper pouring temperature ,mold temperature ,so that can make sure the products achieve a good state of body tissue during the transition from Liquid to solid states.
(5).Mould forming: Pouring when the molten iron temperature difference between molten iron and the molds. In this way ,the ball can achieve internal organization of grain refinement and be more dense .Meanwhile ,the carbide is radically arranged ,and such Carbide is embedded in the matrix again during grinidng process, forming harde layer continuously .So that the hardness and thoughness is maintained to a reasonable.
(6).Heat treatment: We have two sets of heat treatment production line .One is oil quenching, the other is air quenching ,so that the grinding balls can be burring through quenching. And the grinding media has the characters of high hardness ,good thoughness,low wear rate ,low break rate, wear -resistant etc. through tempering

- Q:How do casting parts remove stress?
- Annealing treatment, according to different casting annealing treatment, eliminate thermal stress, if need to restore hardness or increase hardness, and then quenching treatment
- Q:What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?
- For the nodular cast iron, the hardness, strength and wear resistance are improved, such as used in the manufacture of automobile, tractor, diesel engine crankshaft, connecting rod and other important parts. A normalizing and hypereutectoid ball annealing before, can eliminate the mesh two cementite spheroidizing annealing, to ensure that all spheres of cementite. Annealing is a metal heat treatment process, which means the metal is slowly heated to a certain temperature, sufficient for a long time, and then cooled at an appropriate speed. The purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize size, reduce deformation and crack tendency, refine grain, adjust microstructure and eliminate tissue defects. Its purpose: (1) reduce hardness and improve machinability; (2) eliminate residual stress, stabilize size, reduce deformation and crack tendency; (3) refine grain, adjust microstructure and eliminate tissue defects. In production, annealing process is widely used.
- Q:Shandong foundry, casting small pieces of precision casting
- Small foundry in Shandong too much, like many of us in Qingdao, then Dongying Changshun investment casting is a home, they are also casting precision casting equipment, specifically what I recommend that local enterprises, far is not convenient,
- Q:ZGMn13 casting parts processing, with what knife head good?
- The ZGMn13 itself is not have processing, if only the processing point, sharpening, ordinary can, if the processing area is relatively large, ZGMn13 external impact load is bigger, its surface wear resistance is high; the two is with the gradual wear of surface hardening, the hardening layer is continuously formed new if you have suggestions, processing, plasma cutting or flame cutting try
- Q:What kind of flaw detector is better for casting parts?
- Casting using the detector test, you must first determine the detection process, such as the detection of surface and near surface crack defects, such as casting, recommended by CYD-3000, or CYD-5000 mobile magnetic testing machine for testing.
- Q:How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.
- Yantai five God casting is generally 53 yuan /kg, the appearance is quite beautiful
- Q:What do you mean by "proofing" in the casting? Do you charge for the proofing?
- Proofing? In the casting industry is not called proofing, proofing is generally used in the printing industry, that is, according to the customer's drawings or samples, to do a first piece, to provide customers with the inspection process to meet their requirements;In the foundry industry, providing prototypes is sometimes difficult:1, customers if the provision of mold, it would be best, at this time, sample costs are very low, and almost the same as your regular products;2, the customer does not provide the mold, but in business relationships, your factory and not very sure must take this one, it requires your leadership decision-making, is free or low cost, or by a strict process offer (of course sample);3, not all of the casting process to provide samples are difficult, like lost foam can directly make a white NC prototype, and then assembled pouring, this is her unique advantages, first cost less than the opening process and so on;If you don't understand, you can continue to question me
- Q:What is the reason for 304 stainless steel precision casting parts to be changed?
- Mainly because of the cooling shrinkage caused by internal stress caused. There is the change of temperature distribution in materials element imbalance, is typical of surface and internal, thin wall and thick wall, bottom and top.
- Q:The casting defects of pores, trachoma how to repair?
- If the repair after the high temperature resistance, choose LT737 high temperature repair agent.
- Q:Selection of hydraulic press is the casting parts and steel plate welding, how to choose?
- Casting parts in one shape, the overall processing in this regard than steel plate welding better. The same price is much more expensive than steel. Large hydraulic presses seldom have casting parts.
