4.Low brake
5.High hardness forged grinding balls for cement

Features of Forged Steel Grinding Ball:

1. High hardness
2. Good wear resistance
3. High toughness
4. No mal-roundness

Characteristics of High Hardness Forged Grinding Ball for Mining:

We have the unique automatic production line of grinding cylpebs in China, which is independently researched and self-developed by xin nanfang’s R&D center. With the self-developed raw materials and special heat treatment system, xin nanfang’s cylpebs achieve good properties, such as high hardness, martensite or bainite metallographic structure and good wear resistance, etc.

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: Casting parts need to be subjected to the kind of heat treatment after the weldment is finished: 1, gray cast iron: General graphite annealing, to be heat treatment annealing, surface hardening etc.; ductile iron can be various: annealing, normalizing, quenching and isothermal quenching, surface treatment, chemical heat treatment.2. Pouring liquid metal into the casting cavity which adapts to the shape of parts. After cooling and solidification, the casting method is called casting. Castings obtained by casting are called castings. Casting structure design: ensure the working performance and mechanical performance requirements, consider the technical requirements and performance of alloy casting casting casting structure, casting structure design is reasonable or not, the casting quality, productivity and cost has a great influence.3. Heat treatment is a metal hot working process in which the material is in solid state by means of heating, heat preservation and cooling to obtain desired microstructure and properties

Q: It is generally said that cast iron is re smelted by pig iron. My question is..:1 pig iron for melting iron, is directly cast into products (such as bed cover, etc.); or that is just the first pig iron smelting iron casting, such as to cover, bed and other products, will once again cast iron melt to casting?2, there are many castings to the engine. Are these castings made by the engine manufacturer themselves or bought by others?There is no need to answer all. Thank you！！！: As a pig iron smelting, iron smelting belongs to physical, two belongs to the chemical refining, smelting, smelting generally not as a product after use, the product can be used as a chemical composition and casting the two refining, in general is to scrap as additional material after melting making products; engine castings have professional manufacturers making castings. You can own professional production of engine castings.

Q: What are the casting parts tested?: The surface brightness, appearance, size, chemical composition, weight, material, surface defects, internal defects, seals need to be checked, leakage, etc.

Q: What is the difference between casting and stamping parts?: Separation process is also called blanking, the purpose is to make the stamping parts along a certain contour line from the sheet metal separation, at the same time guarantee the quality requirements of the separation section. Stamping is a highly efficient production methods, the use of compound die, especially the multi station progressive die stamping process can be completed in a multi machine, realized by belt uncoiling, leveling, punching, forming and finishing automatic production. High production efficiency, good working conditions, low production costs, can produce hundreds of parts per minute.

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.

Q: What foundry factories are used in the casting parts of China's major automobile manufacturers?: For example Changchun FAW, under a casting, two casting and other casting plant, but there are more than half of all outsourcing in Tianjin Hebei Shandong purchase, many automobile enterprises to casting foundry.

Q: Heat treatment process and purpose of casting parts: Objective: to stabilize tissues, eliminate or substantially reduce internal stress.

Q: What reason is the bronze statue choking fire?: The casting process in boiling phenomenon, is the setting of the exhaust hole positioner position or number is not reasonable, the air cavity can not be discharged, overwhelmed by a material inlet, reflux, change mould, sincerely help you look forward to adopt,

Q: What's the cause of the choking of the casting?,: 3. when casting the environment is humid, sand mold has not removed the moisture, when the casting, the moisture instantaneous transforms into the steam, causes the blowhole
