Description

Archives of Foundry Engineering continues the publishing activity started by Foundry Commission of the Polish Academy of Sciences (PAN) in Katowice in 1978. The initiator of it was the first Chairman Professor Dr Eng. Wacław Sakwa – Corresponding Member of PAN, Honorary Doctor of Czestochowa University of Technology and Silesian University of Technology. This periodical first name was „Solidification of Metals and Alloys” , and made possible to publish the results of works achieved in the field of the Basic Problems Research Cooperation. The subject of publications was related to the title of the periodical and concerned widely understand problems of metals and alloys crystallization in a casting mold. In 1978-2000 the 44 issues have been published. Since 2001 the Foundry Commission has had patronage of the annually published “Archives of Foundry” and since 2007 quarterly published “Archives of Foundry Engineering”. Thematic scope includes scientific issues of foundry industry:

  • Theoretical Aspects of Casting Processes,
  • Innovative Foundry Technologies and Materials,
  • Foundry Processes Computer Aiding,
  • Mechanization, Automation and Robotics in Foundry,
  • Transport Systems in Foundry,
  • Castings Quality Management,
  • Environmental Protection.

Abstract

The herein paper contains the results of investigations on a new type of cellulose blend used for the manufacture of profiles applied in the

process of making gating systems in the foundry industry. A standard cellulose profile was subjected to an experiment. During the

experiment the profile was filled with a liquid cast iron and at the same time the temperatures of the liquid metal crystallizing inside the

profile were measured as well as the temperature of the outer layer of the profile was controlled. Further, the microstructure of the cast

iron, which crystallized out inside the cellulose profile, was analysed and the cellulose, thermally degraded after the experiment, was

verified with the use of the chemical analysis method. Moreover, a quality analysis of the original as well as the degraded cellulose profile

was run with the use of the FTIR infrared spectroscopy. The presented results revealed that the cellulose blend is aluminium silicate

enriched and contains organic binder additives. The cast iron, which crystallized out, tended to have an equilibrium pearlitic structure with

the release of graphite and carbides. The generation of disequilibrium ausferrite phases was also observed in the structure.
