Description

Technical Field

[0001] The utility model relates to the technical field of steel metallurgy continuous casting, in particular to an automatic cooling spray device for a slab continuous casting machine. Background Art

[0002] Continuous casting is a crucial process in steel production, transforming high-temperature liquid steel into solid ingots. Water cooling is a crucial step in the tail-capping process of the continuous casting mold. The original tail-capping water pipe cooling method had the following problems: uneven cooling could easily cause molten steel to spurt out of the mold, resulting in minor local explosions and significant safety hazards for on-site operators; uneven cooling at the mold cap could easily lead to surface quality defects in the ingots, causing numerous surface reassessments and user quality objections; excessive cooling could cause the ingots to become too dark, making it difficult to pull and damaging equipment; and excessive cooling could lead to uneven solidification of the molten steel at the tail of the ingot, resulting in uneven shell thickness. Molten steel could easily escape from thinner areas of the shell, causing leaks in the fan-shaped sections.

[0003] Therefore, in the closing process of the continuous casting crystallizer, in order to ensure that the tail billet of the continuous casting does not leak steel in the fan-shaped section or the billet is too black, and the molten steel at the tail of the billet is solidified in the crystallizer, it is necessary to design a spray cooling device that can both ensure the cooling effect and control the time. The cooling water enters the crystallizer after passing through the spray pipe to meet the safety production and quality requirements. Utility Model Content
