Abstract: Yingfeng Cast Steel Co., Ltd. has rich experience in casting large-scale cast steel slag can products and the industry's top computer simulation technology to design and optimize large-scale cast steel slag tank process plan, achieving the purpose of predicting and preventing casting defects. To ensure the production of large cast steel slag tank castings.
How to predict and prevent casting defects and ensure the production of cast steel slag tanks
Along with the rapid development of the foundry industry at home and abroad, the scale of production continues to increase, and the nominal capacity of single furnace body has developed to a large scale. Therefore, the large-scale development of the volume and weight of the steel slag and liquid water has become an inevitable trend. The product structure of our company is also adjusted with the market changes. The large weight of cast steel slag tanks is gradually increasing. Some users' slag tanks have only individual dimensions and structural schematics, and secondary design is needed. Therefore, the development of large cast steel slag tanks is It is imperative. Slag tanks can be divided into different categories. Our company mainly produces cast steel slag tanks.
1. Technical requirements for cast steel slag tanks
Cast steel slag tanks must be produced in strict accordance with national implementation standards. When using the canning machine to tilt the slag pot, ensure the coaxiality and dimensional accuracy of the slag can trunnion and the inverted can ear portion. The surface of the slag irrigation should be smooth, and the non-machined surface must not have visible casting defects such as shrinkage, porosity, cracks, and slag inclusion.
2. With the development of the foundry industry, the gating system is constantly improving and the technology is constantly improving. In the riser treatment, after the cutting, the bubble repair is performed, the root of the riser at the leg is leveled, and then the height of the slag pot is adjusted to ensure the unevenness of the slag pot. At the same time, it is necessary to improve the dimensional accuracy of the slag tank, and change the ear of the slag can from the processing to the hair casting, and design the special positioning fixing plate and the styling inspection model to ensure the coaxiality and tolerance of the ear can. The size and machining allowance of other parts are adjusted to improve the tolerance level, so as to reduce the margin and reduce the cost.
Through the application of computer simulation technology in cast steel slag tank, it is more accurate to predict the problems that occur in the solidification process of castings, and to adjust the corresponding countermeasures and process parameters for these problems, optimize the process plan, and prevent the defects of castings. Production ensures the quality of castings, reduces production costs, and ensures the smooth production of large slag tanks.
