Innovative! Machine Tool Casting Synthesis Technology to
Help Casting Enterprises to Reduce Efficiency
2017-10-12    From:
Recently, the Chinese foundry industry is facing downward pressure, on the one hand, machine tools, cast iron and other raw materials prices remain high, on the other hand machine tool casting orders limited, making a large number of casting machine tooling operating costs are greater, many companies appear cut Discontinued status.

This year, through painstaking research, and finally realized the use of synthetic technology to produce cast iron machine castings.

Since the price of scrap is much lower than that of foundry pig iron, most of the amount of pig iron added in production is replaced with scrap and carbon agent. The use of furnace scrap and converter iron synthesis technology is used to produce cast iron pieces by adding carbon stabilization and optimizing product performance.

This method to increase the amount of pig iron from the original 70% to 20% -30%, scrap from the original 20% to 50% now, tons of steel costs reduced by 612 RMB / ton.

It is worth mentioning that the use of synthetic technology to produce large cast iron, not only reduces the cost of casting performance also has a certain upgrade.

The traditional process of production of cast iron platform, due to the large amount of pig iron, and there are many pig iron with a large unpackaged over eutectic graphite, increasing the tendency of iron liquid contraction, the production of castings prone to defects.

The new synthesis technology can improve the graphitization capacity of molten iron, and the molten iron is more pure, can prevent or reduce the tendency to shrink. The addition of carbon to increase the number, size, distribution and morphology of the graphite in the molten iron, such as the shortness of the graphite, which reduces the influence of the reduction or passivation of the graphite nuclei during the melting of the furnace, Carbon body, white mouth tends to decrease. At the same time, the use of machine tool casting technology to significantly increase the amount of pearlite and thinning, the material strength and hardness, plasticity and toughness has improved.
