Abstract:
Ductile iron is one of the youngest material with unique constructions features, preferred combination of foundry and mechanical properties. To achieve the necessary quality ductile iron was necessary to establish the methods of control of liquid metal. The most modern and most accurate method is thermal analysis. This is quantitative criterion which comprehensively evaluates the made iron. Thermal analysis has been used in foundries for many years. Development in the field of electronics has resulted in quicker digital tools and displays, mainly for the determination of carbon and silicon contents and carbon equivalent. The displayed results include the previously mentioned information along with other estimated values such as the risk of the presence of carbides or microshrinkage and nodularization protential. Thermal analysis equipment provides a more accurate interpretation of the information available in the curves by taking into account the first and second derivatives of the cooling curves. Our aim was to examine changes in the metallurgical process and batching on the mechanical properties and structure of metal in compliance with the liquidus temperature. From the cooling curves and their derivations were observed process crystallization, graphitization ability, addiction to shrinkages and result structure in the production of ductile iron EN-GJS400-18.
