Abstract

FIELD: roller-type quenching equipment of heat treatment line. SUBSTANCE: equipment for cooling by gas stream has two or more jet nozzles arranged along axis of cooling rollers through metallic strip. Width of jet nozzles is less than that of metallic strip. Jet nozzles are mounted with possibility of motion along motion direction of cooling rollers. At least one jet nozzle may move along axis of roller. Process is realized with use of apparatus controlling pressure or velocity of cooling gas stream fed to each nozzle. Small-width jet nozzles move directly over hot zones usually being W-shaped and having small dimension along width of non-uniform distribution of temperature. Cooling gas is forced to said zones. Pressure or velocity of cooling gas flow is controlled by means of special apparatus providing concentric cooling of hot zones. EFFECT: effective elimination of non-uniform temperature distribution.

Предлагаемое изобретение относится к устройству и способу охлаждения металлических полос в роликовом закалочном оборудовании линии тепловой обработки, которое предусматривает использование оборудования для охлаждения газовой струей, в котором две или более насадок сопел расположены по направлению оси охлаждающих роликов через металлическую полосу, ширина насадок сопел меньше ширины металлической полосы, а сами насадки сопел установлены с возможностью перемещения вдоль направления движения охлаждающих роликов и как минимум одна из насадок сопел может перемещаться вдоль оси ролика; использование устройства регулирования газа предназначено для регулирования давления или скорости потока охлаждающего газа, поступающего в каждую насадку. В зависимости от подобной конструкции насадки сопел узкой ширины перемещаются непосредственно над горячими точками, обычно имеющими форму буквы W и небольшой размер по ширине неравномерного распределения температуры, а охлаждающий газ нагнетается в эти горячие точки, причем давление или скорость потока этого охлаждающего газа регулируется с помощью специального устройства регулирования газа, благодаря чему осуществляется концентрическое охлаждение горячих точек и тем самым эффективно устраняется неравномерное распределение температуры.The present invention relates to a device and method for cooling metal strips in roller quenching equipment of a heat treatment line, which involves the use of gas jet cooling equipment in which two or more nozzles of nozzles are located in the direction of the axis of the cooling rollers through a metal strip, the width of nozzles of nozzles is less than the width of the metal strip, and the nozzle nozzles themselves are installed with the possibility of movement along the direction of movement of the cooling rollers and at least one and nozzle headers is movable along the axis of the roller; the use of a gas control device is designed to control the pressure or flow rate of the cooling gas entering each nozzle. Depending on this design, nozzles of narrow-width nozzles move directly above the hot spots, usually having the shape of the letter W and a small size along the width of the uneven temperature distribution, and the cooling gas is pumped into these hot spots, and the pressure or flow rate of this cooling gas is regulated using a special gas control devices, due to which concentric cooling of hot spots is carried out and thereby uneven tempo distribution is effectively eliminated Aturi.
