Ball
Outline
According to the production process into ball grinding ball, forged steel ball , casting ball ; based on processing of materials into ball bearings, steel balls, steel balls, alloy ball. Wherein the ball is a carbon alloy , chromium, manganese , molybdenum and other metals as the main additive elements , and generated by the forging , spinning, casting, rolling and a spherical -shaped manner alloy wear body , which is pulverized industry today mine with the ball , cement , etc. The most important part of the ball .

Classification of the ball
 [ 1 ]
Categories from the application point of view, can be divided into ball bearing ball grinding steel balls grinding industrial applications and applications on industrial precision bearings on two major categories. Grinding steel balls ( short balls ) is today the most widely used industrial products practice , there is a saying : "There must be crushing industry ," says this very apt ; ball bearings precision bearings use history in the field of industrial and domestic a long , narrow ball should be called on ( commonly known as the steel ball ) .
Ball is a ball , pan- shaped steel sections and grinding said . From appearance to points, can be divided into positive round ball ( now generally narrow appellation ) , capsules ball , oval ball , yin and yang balls, hollow balls, multi-faceted balls , multi lack of ball ( have nests pits on the surface of the body ) and so on .
Ball production generally forging, rolling, semi-solid molding and casting of the four categories. Due to historical practice and processing industries along some special conditions of use and integrated environment , background, in these industries , forging and rolling the ball occupies a large proportion. It has a semi-solid forming unconventional casting, die casting can not be explained simply clear the non- characteristic , like in a cast , like superior performance forging, casting and forging advantages of a combination of advanced technology and the formation of a cause for concern . The ball is casting its simple , flexible and reliable production methods, and easy to implement large-scale production of low investment in the expansion of advantages, especially when the experts and engineers face furnaces using a variety of advanced technology and design of alloy composition , play Endless imagination to create one after another newer, more advanced species, to meet the requirements of competition brought about a sense of accomplishment , but also very people who can appreciate . High cost and potential natural cast ball sustainable development , making today's crushing industry, especially the production of cement grinding industrial ball doing my main force.
Common casting balls according to their chemical composition can be broadly divided into the following eleven categories :
1 , chrome cast iron ball wear ;
2 , low-alloy steel wear casting ball ;
3 , high alloy steel wear cast ball ;
4, high manganese steel ball ;
5 , semi-steel semi- iron ball ;
6 , manganese ductile iron ball ;
7 , Obey , Mabe composite ball ;
8, BAD, CAD wear casting ball ;
9 , special alloy cast iron ball ;
10 wet abrasion resistant casting ball ;
11 , the other cast ball .
Development of the ball
Ball is an important basic components , precision industrial balls in particular plays a huge role in national economic development . In some special conditions , often require special materials of the ball, to complete the different environments , the required functions. In fact, some of the special material ball has been widely used in various fields of the national economy , including the 9Cr18, 3Cr13 stainless steel, copper , aluminum , titanium and steel and agate , glass, ceramic ball. Their application, not only promoted the development of the steel ball manufacturing industry , but also to promote the technological development of related industries and technological progress .
Post- ball production
Ball production process after that ball automatic cleaning, automatic visual inspection ( automatic reject substandard goods ) , auto rust , counting packaging, are affecting the quality of key ball . Ball Ball appearance inspection process is indispensable process. Ball visual inspection includes surface scratches , rust spots and other aspects of the detection surface . Ball production process: Stamping - light wear - quenching - hard grind - Appearance - Lapping - Cleaning - rust - product packaging .
Ball uses
Ball is widely used in bearings, hardware , electronics , iron , machinery, electric power, mining, metallurgy and other fields.

Factors that affect the quality of the ball
① Material Density : ball , cast iron ball , steel ball , different materials of different density , density of steel is greater than that of cast iron , steel is in accordance with the density and content of the main alloying elements varies.
② ball manufacturing method effects: the ball rolling and forging its dense , so the density, casting steel ball , ball or cast iron alloy ball organization does not even dense , even where there are holes , the density Some .
③ ball impact microstructure: the density of the different crystal structure of martensite , austenite, bainite, and ferrite is not the same , also have an impact on the degree of fine crystal .
④ affect the chemical composition of elements : balls contained in the finished product due to the chemical components such as iron , carbon, chromium, manganese, sulfur, phosphorus and other elements different from the hardness of the ball , with different degrees of wear of the impact influence , in general, chromium large, then the ball high wear resistance .
