Physical modeling of traffic behavior and formation of stagnant zones in a single-line tundish during casting in the conditions of a metallurgical micro-mill

Abstract

моделювання поведінки розплаву формування застійних зон в однострумковому проміжному ковші умовах металургійного The research presented in this paper is aimed at choosing the optimal geometric shape of the tundish box, which must meet the conditions of work in a single-flow tundish with continuous or semi-continuous casting of high-grade or bloom billets in small metallurgical micro-mills. The experiments based on the establishment of a hydrodynamic pattern of metal leakage in the tundish, performed on a physical cold model, were based on the following options: without tundish box (№ 1), asymmetric tundish box with low side, deployed towards the dispenser glass (№ 2), asymmetric tundish box with a low side, deployed in the direction of the nearest narrow wall (№ 3), asymmetric tundish box without side, also deployed in the direction of a narrow wall (№ 4). The best results were shown by broom tundish box deployed towards the nearest narrow wall. But it should be noted that the impact of convec-tive and circulating flows on the lining in this area needs further research. An volume tundish tundish, beaker. was first the narrow tundish. tundish seconds, tundish box design 2 seconds; 3 seconds; a stagnant the tundish box and the tundish nozzle 35–60
