High temperature nano non-burning slide plate and its processing technology

Abstract

The invention relates to a high temperature nanometer non-burning slide plate and a processing technique thereof. By applying a method for shaping for many times, namely, a primary shaped slide plate is prepared firstly, and then slide plates in line of dimension requirement are shaped through gradually expanding outwards for several times on this basis; the slide plate is integrated structure. By applying the method of shaping for many times and the progressive way, the slide plate is more compactly pressed, and the primary shaping dimension is big; thus the primary shaped slide plate is not easy to deform and damage even through being pressed during the secondary shaping; meanwhile, the slide plate is provided with a reinforcing pipe to provide stress load during the pressing process, thus the shaping quality of the slide plate is further guaranteed; meanwhile, the reinforcing pipe is further arranged to be a hollow pipe, thus the reinforcing pipe can play a certain bearing effect during the secondary shaping and the third shaping; the reinforcing pipe also can be deformed and compactly inlaid in the groove for being pressed, thus the shaping quality and compact consistence of the slide plate are guaranteed.

Description

technical field [0001] The invention relates to a high-temperature nano non-burning sliding plate and a processing technology thereof, belonging to the technical field of refractory materials. Background technique [0002] In recent decades, new technologies for iron and steel smelting have developed rapidly. With the continuous development of continuous casting technology, the requirements for refractory materials for continuous casting have also increased. In order to meet the new generation of continuous casting technology, it must have excellent thermal shock resistance, high temperature flexural strength and thermal shock resistance. The sliding plate is a functional refractory material for steelmaking and continuous casting, which plays a role in controlling and regulating the flow of molten steel. Its quality level determines the service life, and its reliability is related to the safety of continuous casting production, and also affects the quality of the steel. [...

Problems solved by technology

[0003] The existing skateboard materials are mainly aluminum carbon and aluminum zirconium carbon, which are generally fired in a reducing atmosphere at around 1500 degrees Celsius, which consumes a lot of energy and pollutes the environment

In order to save energy and protect the environment and shorten the production cycle of skateboards, many companies have developed non-burning skateboards, and reduced the firing temperature of the original fired aluminum-carbon skateboards from about 1500 degrees Celsius to about 200 degrees Celsius for baking. 90t ladle continuous casting production, but this type of slide has the disadvantages of low high temperature strength, poor oxidation resistance, etc., and can only be used once
