Problems solved by technology

The flow of molten steel in the slab nozzle of the prior art is concentrated, the flow of molten steel is large, and the slag roll is serious. During the steel casting process, the surface of the cast steel is easily divided into upper and lower layers, and small cracks gather together to form large cracks, which poses quality risks. , affecting the quality of delivery, it is easy to cause the production of scrap steel and waste resources

Abstract

The invention discloses an anti-erosion high-quality casting blank long-service-life slab nozzle. The nozzle comprises a bowl part, a slab nozzle body, a lining, a molten steel channel, a slag line and four side holes, every two of the four side holes correspond to each other, the four side holes are all communicated with the molten steel channel, and the four side holes are specially formed in the side face of the bottom of the slab nozzle. One the one hand, molten steel can flow out from the side face of the slab nozzle body, the molten steel is divided, the flow speed of the molten steel isdecreased, the slag entrapment situation of the molten steel is reduced, tiny cracks and large cracks cannot be formed on the surface of cast steel, the production quality of continuous cast steel isimproved, scrap steel cannot be generated, on the other hand, the shunting effect of the four side holes greatly slows down the flushing and erosion of the molten steel to the slab nozzle and furtherimproves the service life of the slab nozzle, the service life of the slab nozzle is 2-3 times that of an existing slab nozzle, the nozzle does not need to be replaced frequently, resources are saved, the production cost is reduced, and the production requirement of the continuous cast steel is met.

Description

technical field [0001] The invention relates to the technical field of continuous casting of refractory materials, in particular to an erosion-resistant, high-quality cast slab and long-life slab nozzle. Background technique [0002] The slab nozzle is one of the refractory materials used in the tundish continuous casting, mainly used for billet continuous casting to control the flow of molten steel. In recent years, the requirements for steel quality have become more stringent. In order to obtain better quality slabs, many steel mills have paid more attention to the causes of scrap steel. The slab nozzle is the heart of continuous casting steel, which is directly related to the quality of continuous casting steel. . The flow of molten steel in the slab nozzle of the prior art is concentrated, the flow of molten steel is large, and the situation of slag rolling is serious. During the steel casting process, the surface of the cast steel is easily divided into upper and lower...
