Title:
THIN-STRIP CONTINUOUSLY-CAST BAND STEEL COOLING MECHANISM AND COOLING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/119550
Kind Code:
A1
Abstract:
A thin-strip continuously-cast band steel cooling mechanism. Multiple cooling groups (C1, C2, …, Cn) are disposed in the thin-strip continuously-cast band steel cooling mechanism. Each cooling group comprises at least one cooling unit (1), and a cooling manner of each cooling unit in the cooling group is at least one of aerial fog cooling, laminar cooling and jet cooling. The cooling units are located on the upper side and a lower side of a path of a roller, and comprise a collector assembly (2) connected to a water path channel and a gas path channel and at least two collector sub-branches (3) connected to the collector assembly. Multiple nozzles (4) are disposed on the collector sub-branches, and a turn-on-and-off switch (5) used for controlling the cooling units to be turned on or off is disposed on the collector assembly. An opening control valves (6) used for controlling the flows of gas and liquid in the cooling units are also disposed on each of the water path channel and the gas path channel. By means of the cooling mechanism, the cooling speed of the band steel is controlled, and the band steel is uniformly cooled. The present invention also comprises a cooling method using the thin-strip continuously-cast band steel cooling mechanism.
