Rolled Steel Grinding Ball made in Chian with Good Quality Steel and Top Reputation

Q:Where is the precision casting factory?
The National Precision Casting Factory is generally distributed in Shandong, Ji'nan, Jiangsu, Wuxi, Changzhou, Zhejiang, Guangdong, Panyu, Dongguan.The above are only the main distribution, many of Shandong are made supercharger, and Guangdong to jewelry industry based.
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:Can the casting part be phosphating with the phosphating solution of the pickling board?
If it is Phosphating for painting, it is not necessary, because the surface of the casting is rough and can be firmly bonded with the paint film.
Q:How can the casting be quenched and tempered?
Return, general castings (especially steel castings) commonly used heat treatment process is normalized and tempered. Of course there are completely by annealing or remove stress annealing...
Q:The difference between sheet metal and casting parts
Casting parts are made by casting (followed by a variety of processing), the shape can be simple, can also be very complex, usually large parts, as a base, bed, work table, and so on, good seismic performance.
Q:Why does the precision casting factory not usually make iron castings?
Jiangyin Lin Xing stainless steel (precision manufacturing) Co., Ltd. to provide professional precision casting
Q:Explain the heat treatment effect of casting parts, forging parts and welding parts
The three methods of metal processing have one thing in common. They are hot working, which are different in temperature and range of processing. Ductile cast iron is widely used because of its brittleness and poor impact. Heat treatment of cast iron usually adopts the annealing process, reduce the casting effect: 1 because of the internal stress caused by the thermal expansion and contraction, reduce the deformation after machining, decrease surface hardness, improve machining conditions;
Q:Why should pig iron be used in casting?
Cast iron is generally called pig iron, but casting is not merely iron casting.For example, injection molding, die casting, and so on, in fact, cast iron, cast steel, cast aluminum, plastic and so on, can be used in the form of casting processing molding
Q:Casting parts need to be subjected to the kind of heat treatment after the weldment is finished
This is difficult to say, the key is to see the specific parts and components, the final mechanical performance requirements.For example, gray cast iron, usually graphite annealing, to heat treatment annealing, surface quenching and so on, ductile iron can be a variety of annealing, normalizing, quenching and isothermal quenching, surface treatment, chemical treatment and so on, in a word, heat treatment of steel can usually, nodular cast iron can do. Malleable cast iron and vermicular cast iron are often subjected to graphitization annealing and stress relieving annealing, while wear-resistant cast irons often undergo quenching + low temperature tempering, and so on.Welding is the case, such as bearing steel welding must be quenched + low temperature tempering, machine spindle welding (repair welding) must be quenched and tempered treatment, and so on. Of course, if it is a general weld, there is no need for heat treatment or, at most, stress relieving annealing.
Q:In theory, which is more expensive, forging parts or casting parts?
Compared with the price, the product with the same simple structure eliminates the material factorsThe forgings must be more expensive
CDE is one of the largest factory specialized in producing Forged Grinding Balls and Cast Grinding Balls in China. Our annual production of grinding balls is about 100,000 ton.
