The background technology is as follows:
a typical production process of the twin-roll thin strip casting technology is as follows: molten steel uniformly flows and flows in a space surrounded by two casting rolls which are rotated in opposite directions and are cooled by water and a baffle plate of ceramic material to form a molten pool, the molten steel is solidified on the roll surface, and thin strip steel is formed by rolling between the two casting rolls. The double-roller thin-strip casting and rolling process eliminates a series of conventional procedures such as continuous casting (also known as ingot casting), rough rolling, hot continuous rolling, related heating, head cutting and the like, combines a sub-rapid solidification technology and hot working forming into one, and greatly shortens the production process flow of the steel materials. The double-roller thin strip casting and rolling process has the advantages of saving energy by more than 50%, saving equipment investment by about 70% and the like.
The cooling of the molten steel on the surface of the mold is very rapid, and some oxides or other impurities are precipitated and adhere to the surface of the mold, which is difficult to remove in a cold state. These substances affect the uniformity of heat transfer on the surface of the mold, affect the finish of the mold surface, and cause defects on the surface of the strip steel. In the rotating process of the surface of the copper matrix of the crystallizer, a layer of oxide film is formed on the surface due to repeated cold and hot impact, and the layer of oxide film can greatly influence the heat transfer efficiency of the crystallizer, so that the temperature of the surface of the crystallizer is increased, and the strength and the heat transfer performance of the crystallizer are reduced due to secondary crystallization and other reasons.
