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 paper presents the results of simulation of alloy layer formation process on the model casting. The first aim of this study was to

determine the influence of the location of the heat center on alloy layer’s thickness with the use of computer simulation. The second aim of

this study was to predict the thickness of the layer. For changes of technological parameters, the distribution of temperature in the model

casting and temperature changes in the characteristic points of the casting were found for established changes of technological

parameters. Numerical calculations were performed using programs NovaFlow&Solid. The process of obtaining the alloy layer with good

quality and proper thickness depends on: pouring temperature, time of premould hold at the temperature above 1300o

C. The obtained

results of simulation were loaded to authorial program Preforma 1.1 in order to determine the predicted thickness of the alloy casting
