Interaction between refractory and liquid steel study of tundish working linings to analyze stability of forsterite and periclase in front of a liquid steel bath containing dissolved mg and si in solution, the fe-si-mg-o system was studied at different temperatures. Tundish working layer refractory materials uses high quality magnesia or magnesia calcium as raw material,mixed with detonation inhibitor and water reducing agent this product is characterized by easy-construction, good erosion resistance, easy break down after using, and non-crack, can be operated by hand or machine.
5 interesting facts about tundish refractories posted on august 28, 2014 by jason a tundish is an essential component of the continuous casting system in steelmaking.
Our tundish refractories products cover tundish working layer refractory materials,tundish covering agent, tundish nozzle, tundish refractory lining. Researcher in order to study metal flow analysis of tundish and enhancement in the design and physical model also the presented research aiming to develop a new design of tundish with used of available study key words: continuous casting tundish, mathematical modeling, physical modeling, turbulent fluid flow. Refractory lining of a continuous casting tundish in the continuous casting (cc) of steels, tundish is a buffer refractory lined vessel which is located between the ladle and the cc mould the tundish serves the purpose of a reservoir and a distribution vessel over the years, there have been dramatic changes in cc tundish.
The tundish has a key role in casting operations as fluid flow, heat transfer and chemical reactions taking place within it have a strong influence on the quality of steel delivered to the molds one of the main variables to be taken into account is the tundish working lining material in contact with liquid steel. Liquid steel in the tundish and in the ladle heat stored in side wall and bottom of tundish refractory lining, heat losses through the side and bottom shell during an operating tundish cycle, and heat flux distribution through the tundish shell at a given time step figures 2 and 3 show typical graphic outputs fig 2. Refractory lining of a continuous casting tundish in the continuous casting (cc) of steels, tundish is a buffer refractory lined vessel which is located between the ladle and the cc mould the tundish serves the purpose of a reservoir and a distribution vessel.
In order to satisfy the requirement of metallurgical technology development such as clean steel making, high speed casting,lowering non-metallic inclusion, it is necessary to develop high quality tundish refractory with long service life the present project presents the study of basic tundish lining refractory and slag interaction. The molten steel temperature in a tundish has a strong influence on the quality and properties of cast product, caster operation, and refractory life control of melt temperature in a very narrow range is beneficial for improving the quality of the product. The tundish slags have different chemical compositions, liquidus temperatures and viscosity an attempt has been made in the present work to understand the wear mechanisms of mgo-based refractory linings by different tundish slags in the three steel grades.
• refractory materials, as consumables, account for 2-3% of steel production cost however, they have much greater indirect influence on steel production • selection of refractory lining materials and designs are critical for safe, stable, energy efficient, and cost effective steel production. The tundish is a refractory-lined intermediary vessel located between the ladle and the caster it is an integral part of the continuous casting process that directs and controls the.
