Gray iron is a type of cast iron that is widely used in various industries due to its excellent properties such as high strength, good wear resistance, and low cost. The metallurgy of gray iron is a complex process that involves several stages, including melting, casting, and heat treatment.

The alloying of cast iron dates back to the 30s and 40s of the 20th century. The alloying treatment has made a qualitative leap in the performance of cast iron, and at the same time, some special cast irons such as wear resistance, corrosion resistance, and heat resistance have been born. It was also during this period that cast iron was created by gestation. In the late 40s of the 20th century, the inoculated spheroidal graphite cast iron replaced the ordinary flake graphite cast iron, which we call ductile iron.

Iron and steel castings are widely used in various industries due to their excellent mechanical properties and cost-effectiveness. However, the surface quality of castings is crucial for their performance and appearance. In this article, we will discuss the factors that affect the surface quality of iron and steel castings and the methods to improve it.

The method of formulating the model, modeling and core making of large-scale cast steel: the solid wood type is used as the solid wood type of the operating side frame. The wood surface layer is combined with steel, wood and soil to achieve the forming of the inner core box of the frame, meet the shape requirements, and save wood and time. Both the medium sand and the core material in the casting process are very important. In order to make the quality of the frame meet the requirements, the resin is used as the mold and core sand. It can not only ensure the quality requirements of sand mold and sand core, but also improve productivity.

From the perspective of various defects of stainless steel, as well as the causes of these defects, there are many factors that can affect the defects of castings, and the process control of each link will affect the final casting quality. Combined with the casting defects encountered in the past production practice, steel casting manufacturers can strictly control the quality from the following three aspects.

The quality of the steel casting process, the non-standard operating procedures, is also an important factor to test whether the steel casting manufacturers can obtain high-quality castings, with the development of various industries, China will have higher and higher requirements for metal forming products, from now on, China's requirements for metal forming products are getting higher and higher, and the requirements for the casting industry are getting higher and higher, from the current point of view, China's requirements for metal forming products are getting higher and higher in the development of the foundry industry.
