Answer: In the new era of overwhelming big data, traditional foundry enterprises and traditional production methods are seriously challenged. The new words "smart casting" and "digitalization" bring hope and confusion. What exactly is "smart casting"? How far is it from us? "Intelligent casting" is a product of high integration of informatization and casting production, including intelligent casting technology and intelligent casting system. Intelligent casting technology includes numerical simulation, 3D printing, robots, ERP, etc. The intelligent casting system is a big data knowledge base with learning ability, which can carry out self-planning and self-improvement through the comparative analysis of environmental information and self-information. The typical application mode of "Intelligent Foundry" is "Digital Foundry". The "Digital Foundry" adopts information technology to manage all internal processes such as production process, quality control process, financial process, product development process, human resource management training process, etc. Use information technology to deal with the related processes with suppliers and customers. The entire production process can be simulated and controlled. In the "digital foundry", heavy physical labor is basically eliminated, 80% of employees can work in air-conditioned rooms, the environment is clean, and production efficiency and benefits are greatly improved. "Intelligent casting" is not far from us. At present, many factories in China have begun to build "digital foundries" or "smart foundry workshops", which will meet with you during the "13th Five-Year Plan" period.
The equipment and technologies required for "intelligent casting" are becoming more and more mature in the Chinese market, and will be systematically displayed at the "14th China International Foundry Expo": One of the necessary equipment and technologies for intelligent casting is rapid prototyping equipment. Rapid prototyping is divided into additive rapid prototyping (or 3D printing) and subtractive rapid prototyping. Both rapid prototyping methods have mold-free rapid free forming, near-net forming and even net forming of complex components, fully digital, highly flexible, and can be Realize the characteristics of multi-material arbitrary composite manufacturing. It is an effective tool for the rapid development of new products, and it is also an essential production equipment for "smart manufacturing".
The second necessary equipment and technology for intelligent casting is robots. Accuracy and high efficiency are typical characteristics of intelligent casting, and robots are the ideal choice for “smart casting” and are also necessary production equipment. Work side by side with workers or work independently.
The third of the necessary equipment and technology for intelligent casting is simulation. In recent years, my country's casting simulation technology has a strong momentum of research and development in the casting and forming of light metal materials, and important progress has been made in the macro/micro modeling and simulation research of aluminum and magnesium alloy casting and solidification process, and the micro simulation of casting filling and solidification process. . The scale of microscopic simulation includes nanoscale, microscale and millimeter scale, involving various aspects such as crystal growth and nucleation, the transformation of dendrites and columnar crystals to the control of metal matrix. In addition, quality control simulations are moving towards microstructure simulations, performance and service life predictions.
The fourth essential equipment and technology for intelligent casting is virtual manufacturing. Virtual manufacturing is one of the effective ways for "digital foundry" to improve production efficiency, including virtual design, virtual inspection, simulation analysis, etc. Through "human brain + computer" and big data resources, the quality of products can be found and solved before formal production. , cost, efficiency, key parameters and other issues, thereby greatly improving production efficiency and product quality. At present, these virtual manufacturing technologies are increasingly mature in China. (Source/Internet, Editor/Jing Liwen)
