摘要： A method of controlling heat flux between the casting pool and the surfaces of the casting roll in a strip steel casting process includes controlling the concentration of nitrogen in the steel melt. The concentration of nitrogen may be controlled to achieve an operational heat transfer to the casting roll. The heat flux to the casting rolls may be controlled by maintaining the sum of partial pressures calculated from the nitrogen and hydrogen concentrations in the casting pool below 1.15 atmospheres. Decreasing the concentration of nitrogen can increase heat flux at the casting rolls.

摘要： A refractory material for steel making is comprised of 50 to 95% zirconia (ZrO 2 ), 0 to 35% silica (SiO 2 ), 5 to 35% carbon (C), less than 5% alumina (Al 2 O 3 ) and anti-oxidant such as silicon (Si) metal and a carbide. The anti-oxidant maybe in amounts up to about 10% by weight. The refractory material has application in making delivery nozzles and transition pieces. Disclosed also is a method of continuous casting steel strip comprising the steps of assembling a pair of casting rolls having a nip between them; assembling a delivery system for delivering molten steel to form a casting pool comprised of at least some refractory material for contacting the molten steel comprised of 50 to 95% zirconia, 0 to 35% silica, 5 to 35% carbon, less than 5% alumina and anti-oxidant and carbides, and rotating the casting rolls to form thin steel strip delivered downwardly through the nip.
