Description

щий газ по системе трубопроводов поступает в охлаждающие короба 3. В зоне предварительного охлаждени  (фиг. 1) охлаждение изделий осуществл етс  за счет теплообмена с холодной поверхностью стальной пластины охлаждающего короба 3. В зоне окончательного охлаждени  6 охлаждение изделий происходит за счет воздействи  на них высокоскоростных струй газа, истекающего из сопл 4.The gas flows through the piping system to the cooling ducts 3. In the pre-cooling zone (Fig. 1), the products are cooled by heat exchange with the cold surface of the steel plate of the cooling box 3. In the final cooling zone 6, products are cooled by high-speed gas jets flowing out of nozzles 4.

Охлаждающий газ можно направл ть в короба 3 зоны окончательного охлаждени  6 (фиг. 4), где он, истека  из сопл 4, охлаждает издели  до требуемой температуры, а затем отсасываетс  вентил тором 9 по системе трубопроводов 8 и нагнетаетс  в короба 3 зоны предварительного охлаждени  5.The cooling gas can be directed to the box 3 of the final cooling zone 6 (Fig. 4), where it, having flowed from the nozzles 4, cools the products to the required temperature, and then is sucked off by the fan 9 through the piping system 8 and is injected into the box 3 of the pre-cooling zones five.

Охлаждающий газ может проходить первоначально через полость 11, затем поступает в полость 12, откуда истекает через сопла 4 на охлаждаемые слитки; при этом сам газ охлаждаетс  за счет поперечного омывапи  сопл газом в полости 11. В этом случае одиовременно реализуетс  радиационный и конвективный режимы теплообмена, охлаждение ироисходит высокоскоростными стру ми и за счет холодной поверхности стальной плиты полости 11.The cooling gas can pass initially through the cavity 11, then enters the cavity 12, from where it flows through the nozzles 4 to the cooled ingots; at the same time, the gas itself is cooled by transversely washing the nozzles with gas in cavity 11. In this case, radiation and convective modes of heat exchange are simultaneously implemented, cooling and high-speed jets occur due to the cold surface of the steel plate of cavity 11.

В предложенном устройстве повышаетс  эффективность использовани  охлаждени  газа.In the proposed device, the efficiency of using gas cooling is improved.
