INNOVATIVE TECHNOLOGY
Production of massive slag pots with increased operating parameters (SLAG LADLE TECH).
The aim of the project was to develop an innovative technology and its implementation for the production of large-size slag pots weighing up to 30 Mg.
Slag Pots were characterized by a number of technological advantages, the implementation of which in the activities of Krakodlew translated into its position on the domestic market and expansion into new foreign markets.
Industrial research and development work
The goals of the project were achieved thanks to industrial research and development works on an innovative technology for the production of heavy slag ladles from high-quality ductile iron and cast steel. As a result, materials and production technology were developed, and an experimental series of a ladle weighing 30 tons was finally produced from a new type of cast steel and a newly developed ductile iron.
News of the project results
The development of an advanced technology of alloy refinement, i.e. cast steel and ductile iron, will allow the production of slag tanks weighing up to 30 tons with increased operating parameters
Increasing the resistance to tensile and elongation of cast iron, - development of proper microstructure and mechanical properties
Increasing the resistance to thermal shocks (thermal fatigue) during their operation at changing temperatures
Optimizing the proportion of perlite and ferrite in the metal matrix in the required wall thickness range of massive slag ladles thanks to the modified mold technology and optimized chemical composition of ductile iron
Reduction of the casting porosity - improvement of swelling and oxidation resistance
Minimization of the residual stresses occurring in the ladle castings to the greatest extent
Macro-scale research
Achieving the assumed project results was a breakthrough for the Applicant, as well as for the Polish foundry industry, so recognized and valued abroad. The most important aspect was the possibility of conducting tests on a "macro" scale, i.e., on full-size prototypes that could be developed and produced. Only a "macro" study allowed for the accurate acquisition and evaluation of scientific and technical information in terms of the product under development and production technology. Such research was not possible without the expenditures described in the project being carried out, neither at the Applicant's nor at external institutions.
