High-end excellent casting quality

High-end excellent casting quality

1. Utilize the alkaline smelting environment of the electric arc furnace to achieve desulfurization and dephosphorization, purification of molten iron and other key smelting links, so as to obtain the most optimized raw molten iron. In the process of the application experiment of this process in a steel company in Shandong, in the process of producing ductile iron 450-15 medium and large ductile iron castings using the duplex process, the main chemical elements of the original molten iron smelted by the electric arc furnace are C3.65 and Si1. 05, MN0.16, S0.017, P0.013. After being poured into the intermediate frequency furnace for fine adjustment of the composition and vulcanization treatment, all the indexes greatly exceed the indexes of the castings produced by the smelting of the intermediate frequency furnace alone.

2. It can realize the stable production of high-quality and uniform high-end castings suitable for various batches of different weights.

3. It can stably produce high-end, heterogeneous, and extreme special castings with high wear resistance, high rigidity, high extension, high and low temperature resistance, corrosion resistance, and impact resistance.

Easy to realize intelligent and automated management

1. Due to centralized smelting, it is convenient to realize automatic smelting, transfer pouring, improve safety factor, save human resources, precise molten iron quality, and optimize smelting efficiency.

2. It is convenient for non-leakage, automation, intelligence, dust removal management, and the dust collection rate is much higher than the intermittent production mode of intermediate frequency furnace with multiple heats.

3. Facilitate the realization of system-wide intelligent management, such as intelligent scheduling, intelligent process control, intelligent warehouse storage, intelligent sales, etc.
