1. How to prevent the above shortcomings and problems of black spots on the surface of metal manufacturing?
The above-mentioned words, if you want to achieve the stated purpose, then there are some preventive measures, which are actually:
Countermeasure 1: Regarding the quality of the raw materials used, at least the raw materials that meet the quality standards should be used. However, it is necessary to strictly implement the development of process equipment standards and operation and use requests, and there are no handling errors to prevent the quality of castings from being compromised. Countermeasure 2: The use of these modifiers or preservatives must not only have good practical effects, but also prevent various problems. Therefore, the amount and application of these modifiers must be strictly controlled. , There is no slight error.
2. For precision investment casting, is there any difference between the forging method and the traditional forging method? In addition, what is the basic request for the casting itself?
For metal manufacturing, its forging method is made of metal. Therefore, there are some differences between it and the traditional forging method. Therefore, the two are different. For the above casting types, the basic request is to clean and tidy the surface of the castings without all the disadvantages and problems, such as slag inclusion, oxide scale, burrs, and cast tumors.
3. For precision cast steel, if it is ladle or missed by the steelmaking furnace, is it related to the casting itself for practical reasons?
For metal manufacturing, if it is possible to pick up or miss the steelmaking furnace, then, for practical reasons, it includes the above-mentioned elements of the casting itself. It may be due to insufficient compressive strength of the mold shell or the application The adhesive is not very good. Therefore, on this issue, the response is yes.
