Description
Technical Field
The invention relates to the technical field of refractory materials for continuous casting, in particular to a zirconium-ceramic combined erosion-resistant material for a submerged nozzle.
Background
In the continuously developing engineering of the steel industry, the aluminum-carbon refractory material for continuous casting is a novel refractory material which has emerged in the last century. The method is gradually popularized from the beginning of application to ladle bricks to tundish continuous casting. Provides technical support for the development of continuous casting technology.
The submerged nozzle material in the refractory material for continuous casting is generally designed by mainly using a resin-bonded Al2O3-C material, in order to strengthen the corrosion resistance, the slag line part is usually formed by bonding materials such as zirconia, graphite and the like into a zirconium-carbon material by resin, and additives (such as SiC, Si and Al) improve the oxidation resistance of the material and ensure that the product meets the requirements of molten steel continuous casting.
In recent years, the molten steel smelting rhythm is accelerated, and the requirements on the refractory materials for continuous casting are higher and higher. In the case of a submerged nozzle, particularly, at a nozzle slag line part (a joint of molten steel and casting powder), because the casting powder with an ultrahigh pulling speed is high in alkali and low in melting point, the zirconium oxide at the nozzle slag line part is inevitably increased, thermal shock of a nozzle is reduced, and an anti-cracking layer has to be arranged on the inner wall of the nozzle, so that the effective wall thickness of the nozzle is thinned, the service life of the nozzle is reduced, and the problem is a contradiction.
Under the condition of ultrahigh machine pulling speed production, in order to ensure the blank shell cooling effect, dissolve the covering slag and prevent slag entrapment and the like, the adjustment range of the immersion depth is only 20-30 mm, and the slag lifting is not obvious due to the deformation of a tundish and other reasons in actual production, so that the slag lifting is almost close to a slag line for use.
The conventional ZrO2-C material has not been able to meet the use requirements of the continuous casting process. When molten steel with high oxygen content is met, the oxidation of carbon of a zirconium carbon material is also accompanied, so that the original submerged nozzle material cannot meet the long-service-life requirement of continuous casting production.
