Fog cooling ring suspension type continuous casting machine crystallizer

Abstract

The invention discloses a fog cooling ring suspension type continuous casting machine crystallizer. The continuous casting machine crystallizer comprises a crystallizer body; the crystallizer body comprises an upper crystallization channel opening and a lower crystallization channel opening; the crystallizer body is provided with a horizontal upper opening cooling channel and a horizontal lower opening cooling channel; the horizontal upper opening cooling channel and the horizontal lower opening cooling channel are communicated through a plurality of vertical cooling channels; a suspension fog cooling ring is further included and is an annular pipe fitting; a secondary water inlet pipe is arranged on the outer side of the suspension fog cooling ring, and a plurality of cooling nozzles are formed in the inner side of the suspension fog cooling ring; and the suspension fog cooling ring is arranged at the bottom of the crystallizer body and is connected with the crystallizer body through a mounting lifting plate, The water spraying height of second-time cooling is adjusted, and therefore the crystallizer is suitable for meeting the requirements of different materials for the continuous casting secondary cooling technology, and the casting quality of a casting is improved.

Description

technical field [0001] The invention relates to a mist cooling ring suspension type continuous casting machine crystallizer, which belongs to the technical field of continuous casting machine crystallizer manufacturing. Background technique [0002] The crystallizer used in metal casting is mainly made of copper and other good heat-conducting metals. By setting cooling channels in the mold, the coolant flowing through the cooling channels absorbs and transfers the heat of molten metal and metal castings. During the process of smelting and casting, the metal molten liquid in fluid form enters the upper mouth of the mold through the diversion groove, and is cooled and crystallized rapidly in the mold. output from the lower port, and enter the next process for heat preservation or secondary cooling. [0003] In the crystallizer in the prior art, after the metal molten liquid enters the crystallization channel, it is cooled by the crystallizer body for the first time, and the m...

Problems solved by technology

However, its disadvantage is that the water spray height of the second cooling is fixed relative to the crystallizer body and cannot be adjusted, and the thermodynamic properties of castings with different textures are not the same. When the castings do not reach the low plasticity zone, the secondary Cooling is easy to cause gradual deformation, which affects the quality of castings; in addition, the cooling water for the second cooling has been heated up, and the cooling effect has declined, and the cooling water channel for the second cooling is restricted, and the overall water flow must be consistent with the The overall water flow in the first cooling channel is consistent, thus resulting in limited applicability of the above crystallizers
