Изобретение относитс к облает термической обработки металлических изделий в нагревательных печах и может быть использовано в металлургической, машиностроительной и других отрасл х промышленности .The invention relates to heat treatment of metal products in heating furnaces and can be used in the metallurgical, engineering and other industries.
Известна секционна печь скоростного нагрева с диаметром рабочего пространства 800 мм € шестью тангенциально установленными ( в кладке печи) стальными соплами дл подачи топливо-воздушной смеси на внутреннюю поверхность кладки печи, на которой и происходит полное сгорание топлива 1.The known sectional furnace of high-speed heating with a working space diameter of 800 mm € six tangentially installed (in the furnace masonry) steel nozzles for supplying the fuel-air mixture to the internal surface of the furnace masonry, on which the complete combustion of fuel 1 occurs.
Недостатками этой печи вл ютс развитие процесса горени на внутренней поверхности кладки и, как следствие, ее перегрев (налипание окалины на поверхности кладки вследствие центробежных сил враш,аюшихс газопотоков); недостаточно высокие скорости нагрева издели и, как следствие, перерасход тепла на процесс.The disadvantages of this furnace are the development of the combustion process on the inner surface of the masonry and, as a result, its overheating (sticking of scale on the masonry surface due to the centrifugal forces of the vras, ayushih gas flows); not enough high heating rate of the product and, as a consequence, the waste of heat on the process.
Известна также печь скоростного струйного нагрева металлических изделий, содержаша футерованную рабочую камеру, горелки с металлическими соплами, установленными от оси печи на рассто нии 0,5-0,65 минимального размера камеры, и транспортирующее устройство .Also known is a furnace of high-speed jet heating of metal products, containing a lined working chamber, burners with metal nozzles mounted from the furnace axis at a distance of 0.5-0.65 of the minimum chamber size, and a transport device.
Одна-ко конструкции такой печи имеютHowever, the design of such a furnace have
недостаточно большие скорости нагреваinsufficiently high heating rates
металла, а также неравномерный нагревmetal, as well as uneven heating
изделий, что приводит к увеличениюудель5 кого расхода топлива.products, which leads to an increase in fuel consumption.
Целью изобретени вл етс повышение скорости нагрева металла и сокрашение удельного расхода топлива.The aim of the invention is to increase the heating rate of the metal and reduce the specific fuel consumption.
Цель обеспечиваетс тем, что сопла горелок равномерно размещены по периметру (окружности) камеры и по длине с шагом , равным 10-12 калибрам диаметра сопла, причем сопла выполнены с возможностью их осевого перемещени на рассто ние, равное 0,03-0,15 минимального размера камеры, а диаметр сопел горелок составл ет 0,01-0,02 поперечного минимального размера камеры.The goal is ensured by the fact that the nozzles of the burners are evenly placed around the perimeter (circumference) of the chamber and along the length with a step equal to 10-12 caliber diameter of the nozzle, and the nozzle is made with the possibility of their axial movement for a distance equal to 0.03-0.15 minimum the size of the chamber, and the diameter of the burner nozzles is 0.01-0.02 of the transverse minimum chamber size.
Теплоотдача при ударе струи о металл 20 определ етс двум основными факторами- температурой и скоростью струи в точке удара.Heat transfer from the impact of a jet on metal 20 is determined by two main factors, temperature and velocity of the jet at the point of impact.
