Electroslag Remelting Technology Of Mature 20crh Alloy Material - China

The electroslag remelting (ESR) process of 20CrH alloy material is an important method to improve its quality, remove inclusions and improve material properties.

The following are some technical points of the electroslag remelting process: 1 - Process flow:

- **Smelting preparation**: The initial alloy material is crushed and formed, and placed in a mold that can withstand high temperatures.

- **Arc establishment**: Through arc heating, a molten pool is formed in the electroslag remelting furnace, and the energy of the arc melts the alloy material.

- **Electroslag reaction**: After melting, the formed molten pool will be covered by electroslag.

The presence of electroslag helps to remove impurities in the melt and ensure the purity of the melt.

- **Solidification process**: During the cooling process, the composition of the molten pool is uniform and the grains are refined, thereby improving the overall performance of the steel.

2 - Raw material selection:

- Select high-purity 20CrH alloy material as the base material to reduce the generation of inclusions during the remelting process.

3 - Electroslag composition and additives:

- Some alloy elements (such as Ni, Mo, V, etc.

) can be added as needed to improve material properties.

- The electroslag material used is generally quartz sand or other oxides to improve melt fluidity and impurity removal effect.

The electroslag remelting process can significantly improve the uniformity and performance of 20CrH alloy materials, which is suitable for the manufacture of parts requiring high strength and wear resistance.
