On the afternoon of June 30, 2017, experts from the 6th National ADI Seminar visited our company to visit and guide. All the experts praised our company's products. Zeng Yicheng, Ma Jingzhong, Gong Jimin and other experts gave our company a great deal of achievements in the ADI industry. High rating and inscription commendation.

The foundry industry is an important foundation of the manufacturing industry in my country and even in the world. The pollution in the production process is relatively similar to that of general industrial production enterprises, mainly including water pollution, air pollution, solid waste and other major aspects (ie "industrial pollution").

There is only one reason for the phenomenon of shrinkage porosity in die castings, which is due to the phase transition shrinkage that exists when the liquid phase is transformed into the solid phase after the metal melt is filled. Since the solidification characteristics of die castings are cooling from the outside to the inside, when the wall thickness of the castings is large, the problem of shrinkage cavities and porosity occurs inside.

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 generation of subcutaneous pores is a comprehensive reaction of improper operation of each link and process in the casting process. The reasons for the formation are complex, and there are many influencing factors. It involves everyone, and every process should arouse everyone's great attention.

Answer: The casting performance of stainless steel castings is poor, the fluidity is poor, the volume shrinkage and linear shrinkage are large, the thermal stress is large, and cracks are prone to occur. Once the casting is cracked, it will not only require a lot of repair work, but also may be scrapped in serious cases, resulting in significant economic losses. Casting cracks are mainly caused by casting structure, casting process, etc. The following measures are generally used to prevent them in production:

When the metal solidifies and shrinks, the defects caused by the molten metal not effectively feeding the casting are called shrinkage defects, including shrinkage holes, shrinkage porosity, shrinkage, and shrinkage.

There are many factors that affect the spheroidization rate and roundness of ductile iron. The following factors are analyzed from three aspects: chemical composition, technological process, and solidification control:

Improving the service life of the induction furnace body is the goal pursued by every foundry worker, and it will also be of great significance to the enterprise. The main factors affecting the service life of the electric furnace crucible are the furnace lining refractory material, the furnace process and the use process, which will be introduced separately below.

There are many types of large ductile iron castings, such as: large diesel engine block, large wheel hub, large ball mill end cover, blast furnace cooling stave, large rolling mill frame, large injection molding machine template, large steam turbine bearing seat, wheel hub in wind power equipment and Bases and waste slag tanks in nuclear power p
