Why is the chemical composition of steel castings so important

30 Jul,2021 UTC+8 Views:

Steel castings are the main products of our company and we have been studied for many years. With the enrichment of various grades of steel in the market, the chemical composition of the steel castings processing has become the key point.

If you want to judge the quality of the product, the most direct way is to use the instrument to test, such as a direct reading spectrometer for analysis, or have more professional personnel to analyze the raw materials of steel castings. This method can be used in a short time. Understand the quality of the chemical composition, or make a ratio of them to achieve the required qualification level.

The cast steel is sampled and analyzed to observe whether the sample has a chemical reaction. At the same time, the staff needs to observe the changes in the chemical composition in the casting furnace at any time, because qualified liquid steel will also be generated after a certain period of time in the casting furnace. For example, if the manganese steel stays in the furnace for a long time, the composition content will become lower. At this time, it is necessary to adopt corresponding methods to ensure the quality of the casting.
After each slag pot is casted, the machine needs to be cleaned up, mainly because the previous processing residue will affect the subsequent results, which is convenient for the later staff to determine the quality of the casting in the later stage.
