Cast steel is a metal object obtained by casting, and cast steel is a work of art created by craftsmen. What are the characteristics of these works of art?
The design of the casting process is based on the structural properties of the casting and, in combination with actual production, not only guarantees quality, but also achieves higher economic benefits and creates compliance with a guaranteed implementation Design a series of operation guidance documents and quality control documents required products.
There are many factors in the design of large castings and a wide variety of design techniques, but some factors that are not noticeable in small pieces can have a significant effect on large pieces. Large castings are scarce, process testing and improvement are difficult, and designers need extensive knowledge and experience.
The process and content mainly include casting technology analysis, selection of casting process plan, selection of casting process parameters, casting molding control, casting heat treatment technology, casting process equipment design, post-cast processing technology, etc. This is the core of the design, the meaning of the casting process design in the usual sense.
Casting process design is compiled based on summaries and improvements, and is a technical management tool for obtaining high quality, high yield castings. When choosing a casting process plan, you must take into account the specific requirements of the foundry, such as the operation of the casting plant, the production capacity, the structure and size of the steel castings, the technical requirements and the output. The following is a preliminary discussion of the main principles of choosing a casting process plan.
Once a casting production process plan has been determined, various casting process parameters must be selected depending on the shape, size, and technical requirements of the product part drawing. The parameters of the casting process are determined by the type of metal and the properties of the casting method.
The contents mainly include casting shrinkage, machining allowance, draft, casting fillet, core size, etc., process correction amount, negative parting number, etc. The choice of casting process parameters must be flexibly applied according to the actual production situation.
