Determination of Process Parameters by Production of Vermicular Cast Iron

Production of vermicular cast iron by method of restricted or exact addition of magnesium treatment alloy is difficult due to very narrow range of residual Mg, which is often less than ± ; ; ; 0, 001%. Crystallization of graphite is not controlled only by residual Mg but also by dissolve oxygen and nitrogen and oxides and silicates present in melt. In this paper influence of chemical composition of treated melts, fading of Mg during the pouring, section thickness (cooling intensity) and inoculation on obtained microstructure properties and hardness of the vermicular cast iron samples (castings) have been analyzed.
