Cooling horizontal continuous casting crystallizer

Abstract

The invention discloses a cooling horizontal continuous casting crystallizer. The crystallizer is provided with a first side part and a second side part which are arranged on the two different sides in the thickness direction correspondingly, wherein the first side part is provided with a plurality of water injection openings and water outlets; the outer surface of the second side part is a cooling face used for making contact with a to-be-cooled graphite mold; a plurality of water flowing grooves distributed at intervals are formed in the crystallizer in the length direction; the length direction of the water flowing grooves extends in the width direction of the crystallizer; and one end of each water flowing groove in the length direction communicates with the corresponding water injection opening, and the other end of each water flowing groove in the length direction communicates with the corresponding water outlet. The cooling effect of the crystallizer is good in the using process, when the crystallizer is matched with the to-be-cooled graphite mold, the cooling face on one side of the crystallizer makes direct face-to-face contact with the graphite mold, the heat conductivityis improved, the cooling effect of molten copper is improved, and the service life of the crystallizer is prolonged.

Description

technical field [0001] The invention relates to a cooling horizontal continuous casting crystallizer. Background technique [0002] The crystallizer is a very important part of the horizontal continuous casting machine. It is a forced water-cooled bottomless ingot mold. Its performance plays a very important role in the production capacity of the continuous casting machine and the quality of the billet. Therefore, it is called continuous casting The "heart" of the device. [0003] The traditional crystallizer usually consists of a stainless steel cooling water jacket and a pure copper crystallizer. The cooling water jacket and the crystallizer are connected by screws. In a high-temperature environment for a long time, due to the difference in thermal conductivity between stainless steel and pure copper, the amount of deformation is different. Water leakage often occurs at the sealing position, which will accelerate the corrosion of the mold, reduce the life of the mold, a...

[0003] The traditional crystallizer usually consists of a stainless steel cooling water jacket and a pure copper crystallizer. The cooling water jacket and the crystallizer are connected by screws. In a high-temperature environment for a long time, due to the difference in thermal conductivity between stainless steel and pure copper, the amount of deformation is different. Water leakage often occurs at the sealing position, which will accelerate the corrosion of the mold, reduce the life of the mold, and have a great impact on the quality of the slab
