(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:What are the requirements for casting steel castings?
- 1, high quality requirements of the surface or the main processing surface should be placed below.
- Q:How can the casting be free of trachoma?
- 3, the gate is not facing sand core, flush sand core, will cause trachoma.
- Q:What are the casting parts processing engineering?
- Among them, special casting has metal mould casting, pressure casting, low pressure casting, lost wax casting (also known as precision casting), shell casting, lost foam casting, centrifugal casting, continuous casting, V casting, and clay casting
- Q:Heat treatment process and purpose of casting parts
- Objective: to stabilize tissues, eliminate or substantially reduce internal stress.
- Q:I often see Waixiejiagong drawings, casting, how to distinguish the latheman.
- Casting rough drawings generally no processing symbols, processing drawings indispensable is processing symbols!
- Q:What are the casting parts used to test shrinkage holes?
- 2. x ray. This method can do nondestructive testing, but the cost is higher. Generally, high castings are required.
- Q:Where is the precision casting factory?
- Shandong, DongyingThe birthplace of precision casting
- 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:What do you mean by "proofing" in the casting? Do you charge for the proofing?
- Proofing refers to making the first sample to confirm to the customer
- Q:Which surface is coarser for cast iron or cast steel castings? Why?
- The surface of the steel is more rough, because the coating sand cast steel cast iron particles compared with graphite coating degree, the other one is to get a better air permeability and collapsibility of sand, the compaction degree is smaller than iron.
