Description

Дл  удлинени  срока службы огнеупорной кладки печей примен ютс  различные конструкции холодильли«о;в , охлаждаемые водой, и, реже, газом или воздухом. Преимуществом такого охлаждени   вл етс  простота устройства и обслуживани . Недостатком его  вл етс  то, что при любой конструкции холодильников охлаждение рабочей поверхности происходит за счет теплопроводности стенок холодильника и теплопередачи от стенок холодильника к стенам кладки, а также и то обсто тельство, что непосредственному охлаждению подвергаетс  лишь незначиФельна  часть рабочей поверхности, равна .поперечному сечению холодильника. Промежуточные , между холодильниками, участки кладки охлаждаютс  только за счет теплопроводности самой кладкИ. Так как теплопроводность огнеупорных материалов относительно невелика, то эффективность охлаждени  на промежуточных участках резко снижаетс .In order to extend the life of the refractory masonry of the furnaces, various designs of refrigerators or plants are used, cooled with water and, less commonly, with gas or air. The advantage of this cooling is the simplicity of the device and its maintenance. Its disadvantage is that in any design of refrigerators the cooling of the working surface occurs due to the thermal conductivity of the walls of the refrigerator and heat transfer from the walls of the refrigerator to the walls of the masonry, as well as the fact that only a small portion of the working surface is directly cooled to the cross section the fridge. Intermediate, between refrigerators, parts of the masonry are cooled only by the thermal conductivity of the masonry itself. Since the thermal conductivity of refractory materials is relatively low, the cooling efficiency at intermediate sites decreases sharply.

В предлагаемом способе охлал даетс  поток гор чего газа, движущегос  вдоль внутренней поверхности рабочего пространства, газом, паром, водой или их смесью, вд}ваемых через фурмы, имеющие только боковые выходы. Выход ща  из бокового отверсти  стру  охлаждаемой среды, дв)га сь вдоль стенки кладки, будет, с одной стороны, слул-;ить защитньп фильмом от гор чих газов, а с другой , лодмешива сь к гор чим газам, будет снижать температзру газа у стен кладки. При вдувании воды или пара, температура газа будет понижатьс  еще и за счет разложени  паров.In the proposed method, a stream of hot gas moving along the inner surface of the working space is cooled by gas, steam, water, or their mixture, blown through tuyeres having only side exits. Outgoing from the side opening, the stream of the cooled medium, moving along the wall of the masonry, will, on the one hand, listen to a protective film from hot gases, and on the other hand, mix up hot gases and reduce the temperature of the gas. masonry walls. When water or steam is blown in, the gas temperature will also decrease due to vapor decomposition.

Предлагаемый способ охлаждени  .может оказатьс  весьма эффективнььм дл  доменных и мартено15ских печей, особенно при работе на кислородном дутье.The proposed cooling method can be very effective for blast furnaces and open-hearth furnaces, especially when operating on oxygen blowing.
