SAND CASTING EQUIPMENT.

In recent years, the output of Austempered Ductile Iron (ADI) cast by Xinyuanzhu Group has increased year by year, of which engineering structural parts and anti-wear and wear-resistant parts (including CADI grinding balls and Aobe grinding balls, etc.) accounted for approximately each half. Engineering structural parts include automobile suspension parts, brackets, control arms, steering knuckles, railway machinery, agricultural machinery and construction machinery parts, as well as gears, crankshafts, etc. With the development of mechanical parts in the direction of high performance and light weight, the production and application of ADI parts have attracted much attention from the industry. Therefore, the basic research on ADI application, production technology and equipment, and the stability of the quality of the blanks are developing rapidly, and the prospects are very good. .

In the process of casting production, Xinyuanzhu Group made the following summary based on the problems that occurred in the casting workshop.
1. Material performance fluctuates greatly: the size difference of different parts of the part design is too large, and the casting and heat treatment process is unstable.
2. Cost pressure: system optimization design is not carried out, weight reduction is insufficient, and overall cost reduction is limited.
3. Competition of other materials: In addition to high-strength steel and aluminum-magnesium alloy materials, high-strength and high-toughness cast ductile iron and iron-type sand coating processes are also growing and improving, competing with ADI castings in certain areas for the market.
4. ADI manufacturers generally do not have component stress analysis and product development capabilities.
5. In the design and development process of the whole vehicle project, the development and trial production lags behind, and the application opportunity is missed.

In view of the above problems, the key is to expand the application range of austempered castings. After many experiments, xinyuanzhu group has obtained the following experience:
1. Improving the quality of castings, especially the stability and consistency of the quality of casting blanks, and enhancing the competitive advantage of ADI castings in the market. This is the prerequisite for the development of austempered castings.
2. Although professional heat treatment centers have been initially formed nationwide, how to choose suitable heat treatment equipment and treatment processes according to the characteristics of castings and optimize them continuously to improve the quality of heat treatment and reduce the cost of heat treatment. Establishing a consortium of ADI castings, heat treatment, and machining, optimizing the supply chain, and enhancing the comprehensive competitiveness of the market is an important task for improving the application scope and promotion speed of ADI castings in the future.
3. The existing material manuals and design manuals have not listed ADI as a mature metal structure material, cultivate and introduce talents, master the stress analysis and product development capabilities of ADI parts, and extensively introduce the excellent comprehensive performance of ADI to make more Many technicians participate in the promotion and application of ADI.
