1. Productivity of Casting and Associated Enterprise
According to inadequate statistics, the production of casting of Shandong Province reaches 632,000 tons in 2017,in which grey iron castings, ductile iron castings, malleable iron castings, vermicular graphite iron castings, ductile iron pipes and tubes, common steel casting, nice steel casting and nonferrous casting take 50%,18%,3.5%,2%,11%8%,2.5%and5%,respectively.Thereare many casting factories in shandong Province, in which more than 1,400 factories are of large ones. There are about 135,000 people engaged in this field.
The castings are mainly used in cars, motorcycles, ships, machine tools, general machinery as well as machinery for engineering, agriculture, railways and construction. They are also used in power industry, metallurgy industry, chemical industry and municipal projects, etc. Some castings are exported to Occident, Japan, Korea and South-east Asian countries.
2. Technical Equipment and Quality Control
Smelting technology: Cupolas and electric furnaces are mainly used. However, some factories use both cupolas and electric furnaces.
Molding technology: Green sand molds have been replaced mainly by resin sand molds. Gas pressing molding line, high-pressure and more touches molding line and extrusion molding line have been introduced to many factories .New technologies, such as minus pressure solid mold casting, lose olefin casting lose olefin casting, vacuum casting, difference to many factories. New technologies, such as minus pressure solid mold casting, lose olefin casting, vacuum casting, difference pressure casting, gravity casting “V method” and Self strengthening sodium silicate technology were used widely.
Simulation technology: Computer simulation technologies for solidification process have found application in factories.
Quality control system: Intelligent analyzer for liquid iron before molding, spectral analyzer, scathe less detector and three-dimensional coordinate measurer are widely used. Most enterprises have passed IS09000 Quality Authentication.
3.Casting Equipment and Material Supply
Casting equipment produced in shandong Province includes molding, smelting, cleaning and sand treating equipment. Pig iron materials such as sand molding and core-making materials, steel balls for sand cleaning and all kinds of fire-resistant materials are all available in Shandong.
4.Industrial conglomeration area:
There is an industrial park called Zhangqiumingshui which is set up under the support of the province. The park contains many kinds of industrial clusters, the clusters can be listed as follow: The industrial cluster of production heavy automobile, blower and non-ferrous alloy casting; the industrial cluster of exporting brake disks in the area of Laizhou; the industrial cluster of production precise casting and equipments in Pingdu and Dongying area; the industrial cluster of production cupola in Jiaozhou area and casing park area in Changyi city; the industrial cluster of production steel shot in Zouping area and supporting cast iron in Qingzhou area.
5.Training of Enterprise Employees：
Shandong University and Shandong University of Architecture are two main training bases for casting engineers in Shandong province. Up to now,2,260 bachelors,320 masters and 61doctors of casting majors have graduated from Shan dong University.1,780 technical graduates graduated from Shandong University of Architecture have joined working force in this area. For training more personnel, the Casting Association and Shandong University have jointly sponsored a college training program for casting specialty since 2002, so far, there have been 60 graduates.
