Quality Improvement.

The use of carbon, rare earths and other trace elements to densify the impurities in steel, changing the structural shape and physical properties of the impurities in the steel, spheroidising the impurities, subdividing them and improving the mechanical properties of the steel.

High temperature diffusion heat treatment of ingots improves the inhomogeneity of the ingot composition and improves the transverse properties of the steel.

In thermal processing, repeated installation of ingots and multi-directional rolling improves the deformation of steel, reduces the amount of carbide segregation in steel, and helps to improve the anisotropy of steel.

The purity of steel has a great impact on the isotropic properties of die steel cr12, the use of secondary accuracy technology (including vacuum accuracy, static pressure accuracy and steel ladle powder, etc.), can improve the purity of steel, especially to reduce the content of harmful impurities in steel, which is conducive to improving the performance of steel.

With the application of high-speed mold steel standard parts more and more widely, mold standardization, the degree of commercialization continues to improve, the quality of mold steel products, varieties of specifications, delivery time, etc. have put forward higher requirements.
