(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: There is a little trace of polishingShock polishing is even worseElectrolysis can not be uneven, there is a slight bump
- German winter three step mirror polishing 2013 new processYou can free proofing!
- Q: How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.
- I am doing this for sale, if the price is mainly based on the product structure, the difficulty of pricing. At present, if it is more formal and material guarantee manufacturers generally in 48-53 yuan /Kg (of course, products have a certain weight, such as greater than 100g), our company's current price of about 53 yuan /Kg or so. .
- Q: What are the factors affecting the machining process of the casting material and structure?
- The impact on the machining is obvious, it should be the material and heat treatment of the castingCarbon steel parts should be treated by heat treatment (annealing) without special conditions. It can effectively prevent the uneven hardness and hard points. It is easy to turn.
- Q: Why does the surface of stainless steel casting mirror mirror ripple?
- Those should be head prints. If required, it would be better to throw with a single grinding head.
- Q: Why do cheap cars like stamping parts instead of casting parts?
- We usually say that the stamping is usually refers to the cold stamping parts, for example, a piece of iron, wants to turn it into a fast food dish, it must design a set of mold, mold is working face plate shape, the pressure plate mold, it becomes you want the dishes, this is the cold stamping die stamping is the direct use of metal materials.Automobile stamping parts are mainly classified according to process, and can be divided into two major parts: separation process and forming process.
- Q: What is the difference between forging parts and casting parts?
- The forging can guarantee the continuity of the metal fiber tissue, make the fiber structure of the forging keep the same shape as the forging, the metal streamline is complete, the tissue is compact, and the mechanical property is good. To ensure that the object has good mechanical properties and long service life, the processing of objects sharp, durable, high strength, first-class quality.
- Q: I often see Waixiejiagong drawings, casting, how to distinguish the latheman.
- The technical condition or the material column in the title column will tell whether it is a casting drawing or not. However, the need for casting drawings, and some also through machining (car, milling, etc.), this should be part of the process drawings, process drawings are described
- Q: The difference between cement sand castings, resin sand castings and vacuum casting parts
- Our country or international, in all casting production in 60 ~ 70% by sand casting is produced, of which about 70% is used in the production of clay sand. The main reason is that the cost of sand casting is low compared with other casting method, simple production process and short production cycle. So as the car engine cylinder body the cylinder head, crankshaft castings are produced using clay wet sand molding process. When the wet type can not meet the requirement to consider the use of clay sand table dry sand, dry sand mold or other sand.
- Q: For example, casting parts contain many holes, inclusions and other defects, the size and the number of holes exceed which limit is not qualified
- For example, the castings shall be in accordance with the requirements of the second types of castings in the technical requirements for aluminum alloy castings of GB/T9438-1999;
- Q: How to solve casting defect casting?
- Prevention methodReduce the gas in the metal liquid and oxidize the slag, improve the fluidity of the metal liquidIncrease pouring temperature and pouring speed, strengthen slag collection, slag block or bottom pouring bag, teapot ladle pouring, can not cut off when pouring, prevent the slag from blocking the nozzle, and cause the casting to breakIncrease the sprue and sprue height, increase the runner section area and the sprue number, and improve the filling speed and the metal hydrostatic headImprove the casting design and increase the thickness of the thin-wall part of the castingChange the pouring position and pouring system, the casting thin wall plane is located at the top and away from the gate, to prevent the filling of liquid metal splashing, eddy current, avoid metal stream in the casting thin sections or core support, cold iron, insert the confluence, when necessary, take horizontal vertical pouring cold or inclined castingIncrease the permeability of core and sand, strengthen the exhaust of mould, and the quantity of air outlet and riser should be enoughChange the size and location of the core, the inner cold iron, the core support, the internal cold iron, the insert should be no rust, no oil pollutionCheck the type, tight box, press the operation of iron is safe, to prevent running fire
