Description

Technical Field

[0001] The utility model relates to the technical field of crystallizers, in particular to a speed-increasing mechanism for a continuous casting machine crystallizer. Background Art

[0002] Continuous steel casting is the process of continuously pouring high-temperature molten steel into billets with defined cross-sectional shapes and dimensions. This process requires continuous casting equipment, which can be categorized into various types. Based on their structural appearance, continuous casting machines can be divided into vertical casting machines, vertical bending casting machines, straight-line arc casting machines, arc casting machines, multi-radius elliptical casting machines, and horizontal casting machines. During operation, a continuous casting machine cools and forms the billet through a mold, then pulls the formed billet out.

[0003] In the prior art, for example, Chinese patent publication number CN219616663U discloses a continuous casting machine crystallizer, comprising a fixed frame, a crystallization box, a copper tube, a cooling channel, and a cooling mechanism. The crystallization box is fixedly mounted on the fixed frame, and a copper tube is disposed inside the crystallization box. A cooling channel is disposed at the bottom of the crystallization box, and a cooling ring is disposed inside the cooling channel. A guide frame is disposed below the discharge port of the cooling channel, and a plurality of guide rollers are disposed above the guide frame. A cooling mechanism is disposed above the guide rollers. The cooling mechanism comprises a fixed frame, a lifting plate, a spray pipe, and an adjusting screw. The fixed frame is mounted on a connecting plate of the guide frame, and a lifting plate is disposed inside the fixed frame. A spray pipe is disposed at the bottom of the lifting plate, and the upper portion of the lifting plate is connected to the screw hole of the fixed frame via an adjusting screw. The present utility model is intended to address the problem that the existing continuous casting machine crystallization cooling is relatively simple and slow.

[0004] The above patent can solve the problem of relatively simple and slow crystallization cooling of the continuous casting machine. However, when the cooling ring is transporting coolant, the coolant enters the cooling ring at the bottom for heat exchange. Therefore, when the coolant enters the top of the cooling ring, the coolant has absorbed enough heat and can no longer cool the steel billet, thereby reducing the use effect of the crystallizer.
