                                              Improve the yield of castings and effectively control defects










Analysis and research on stainless steel casting defects is one of the key technologies to improve the yield of castings. However, the difficulty is not small. Mainly manifested in:
1 involves a wide range of knowledge, such as alloys, casting processes, modeling materials, casting equipment and testing of production processes.
2 The diversity of the causes of casting defects, a defect can be caused by a variety of reasons, and one cause may cause several defects.
3 The restrictive nature of technical measures, such as the use of a certain measure, can prevent a certain type of defect, but may lead to another type of defect.
4 Influencing factors are difficult to control, such as the quality of raw materials, air temperature and humidity.
In order to reduce casting defects and improve the yield of castings, it is necessary to effectively control casting defects. Accurate judgment of defects is a prerequisite for solving casting defects. Therefore, it is necessary for the foundry to understand the various analytical methods of defects, including general and special analytical methods, to determine the type of defects, analyze the causes, and then propose preventive measures, and implement them from technology and management. It is noteworthy that although the types of defects are the same, there are differences in the causes and preventive measures for different cast alloy castings.

                Ten things that must be paid attention to in precision casting! 1. Unblock all obstacles to the channel and site. 2. Check if the ladle is dry, whether the bottom of the bag, the ear, the bag and the end are safe and reliable, and whether the rotation is flexible. Do not use dry Iron ladle. 3, all tools in contact with molten iron, must be preheated to 500 degrees Celsius before use, otherwise it should not be used. 4, the ladle should not exceed 80% of the volume, the ladle should be smooth and slow, keep the steps to prevent the overflow of molten iron. Cast iron 5, before the crane crane should check the iron of the hook, the chain is reliable, the chain is not allowed to knot, there is a person responsible for tracking the iron in the water There must be no staff on the line. 6. Strictly implement the "six will not fall": (1) The temperature of molten iron is not enough; (2) The molten iron grade is not poured; (3) does not b

                                                                   Factors affecting the surface roughness of stainless steel castings Surface roughness is another major quality indicator for stainless steel castings , generally less than 3.2 μm, between 0.8 and 3.2 μm. There are many factors affecting the surface roughness of castings, such as the pressure type, the surface quality of the investment and stainless steel, the casting process, the type of alloy and other factors. (1) Profile and investment surface quality. The surface roughness of the investment mold is the most important part affecting the surface roughness of the casting, and it is related to the surface quality of the molding, the compression molding method and the pressing process parameters. (2) Stainless steel surface quality. Stainless steel is a columnar columnar structure network, and refractory materials, additives, and water are filled in the middle, so that there are pores of different sizes on the su
