Foundry materials contain many different metal elements, some of which have a certain effect on the performance of steel materials, so these elements are usually called beneficial elements such as manganese (Mn), chromium (Cr), cobalt (Co) and nickel (Ni). When the content of these elements reaches a certain level, the various properties of steel will be evident.
In general, if the content of these beneficial elements in the foundry material is sufficient, it will inevitably greatly enhance the workability, strength and wear resistance, heat resistance and corrosion resistance of steel. Moreover, these elements themselves have greater economic value, so if the raw ore contains more of these elements, it can be regarded as a composite ore and can be comprehensively utilized.
In the production of foundry materials, the reduction performance of iron ore in the selected raw materials is a very important indicator. The so-called reducibility mainly refers to the ease with which the iron ore can be reduced by reducibility or hydrogen. This is because if its reducibility ratio is good, it is very advantageous for reducing the coke ratio.
In addition to this, the composition of the raw materials and their own compactness will also affect the quality of the reduction. If the reducibility is poor, the use value of the foundry material will also decrease significantly, which is very unfavorable for the later production work.
Therefore, this factor needs to be taken into consideration when choosing raw foundry materials. In short, when the casting material is equipped, the composition and structure of the selected raw material have an impact on its performance.
