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 mathematical and numerical simulation model of the liquid steel flow in a tundish is presented in this paper. The problem was treated

as a complex and solved by the finite element method. The single-strand slab tundish is used to continuous casting slabs. The internal work

space of the tundish was modified by the following flow control devices. The first device was a striker pad situated in the pouring tundish

zone. The second device was a baffle with three holes and the third device was a baffle without hole. The main purpose of using these

devices was to cause a quiet liquid mixing as well as give directional metal flow upwards which facilitated inclusion floatation. The

interaction of flow control devices on hydrodynamic conditions was received from numerical simulation. As a result of the computations

carried out, the liquid steel flow and steel temperature fields were obtained. The influence of the tundish modification on velocity fields in

the liquid phase of steel was estimated, because these have an essential influence on high quality of a continuous steel cast slab.
