Opis:: The paper presents a new methodology for research on gas generation property of materials used for sand forms and cores, models made of foamed polystyrene, protective layers, etc. In the form of an example, full analysis has been presented of gas generation property of a selected furan resin bonded sand, stating the course and kinetics of gas generation, their intensity in the time function, and in the heating temperature function. The description is of quantitative nature. The existence of peaks in gas generation intensity was observed at several temperature values. The results are well-correlated with the inclination to form surface defects of casts made in furnace resin bonded sands. This is the first study on gas generation kinetics in the mass heating temperature function.

Opis:: The article presents the new technology of the refractory materials used for the ladles and pouring devices. The aim for solving the majority of the problems that originated from the refractory lining was to develop the group of cement-free TRIAD products by Vesuvius company. The cement-free setting system in the TRIAD products eliminates calcium oxide (CaO) that occurs in low and extra low cement concretes resulting in its higher strength at higher temperatures. The features of the new cement-free castables were described. One of the most unique features of this technology is the porous material structure. Small venting microchannels are formed during the concrete setting process. These micro-channels allow for removing water vapor from the lining without affecting its refractory properties. On the other hand, the diameter of pores is so low that it disallows the penetration of slag and metal into the lining, extends its operating life at the same time facilitates cleaning and removing build-ups. The procedure of the preparation of these materials, as well as the method of building of the lining, were presented. An example of the practical use of these materials in the ductile cast iron foundry was presented, showing the advantages of the new refractory materials over the traditional ones.
