Abstract

The invention relates to the technical field of controlled rolling and controlled cooling of hot rolled strips, in particular to a multi-cavity flow-controllable spray header. The spray header comprises a hole damping plate transversely arranged in a water spraying cavity, a nozzle arranged on the lower surface of the spray header, a long partition plate vertically arranged in the length direction of the water spraying cavity, and a plurality of short partition plates arranged in the water spraying cavity; the water spraying cavity is divided into a plurality of independent chambers in different shapes through the hole damping plate, the long partition plate and the short partition plates, and the flows of the chambers are independently controlled; and the good jet fluid shape can be kept under the condition of large-range pressure and flow adjusting. Large-range stepless adjustment of the instant cooling speed of a steel plate can be achieved, the steel plate cooling process has the extremely high uniformity, and fine and uniform cooling of the rolled steel plate can be achieved under the high-strength cooling condition; and the internal texture of the steel plate is uniform, small in stress and good in plate shape, and plate deformation appearing in the production process can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of controlled rolling and controlled cooling of hot-rolled strip steel, in particular to a multi-cavity flow controllable spray header. Background technique [0002] Controlled rolling and controlled cooling technology is widely used in the production of hot-rolled steel products. Controlled rolling is based on adjusting the chemical composition of steel, and controls the state and phase of austenite by controlling heating temperature, rolling temperature, deformation system and other process parameters. Change the structure and state of the product, so as to achieve the purpose of controlling the structure and properties of steel. Controlled cooling is to control the phase transformation conditions, carbide precipitation behavior and austenite structure state by controlling the cooling conditions of the hot-rolled steel after rolling, so as to obtain the ideal structure and performance. [0003] The ultra-...
