The process and method of control for the production of cast iron vermicular

摘要

The process and method of control for the production of cast iron vermicular. The present invention is a process and control method for the manufacture of cast iron vermicular, carried out in two stages of treatment with magnesium alloy. First, the metal is transferred to a pot of leakage or treatment where it is held a pre - treatment or conditioning with magnesium alloy.After this conditioning shall be carried out direct analysis of oxygen content in liquid metal, by means of an electrochemical probe, and also the thermal analysis of liquid metal, by means of conventional glasses samplers with only one thermocouple in its interior.In this way, the quantities of magnesium alloy and inoculant necessary for obtaining iron vermicular are estimated based on the results of these analyses, and then added, leading to formation of graphite vermicular.
