Description
(54) КРИСТАЛЛИЗАТОР(54) CRYSTALIZER
1one
Изобретение относитс к металлургии, в частности, к непрерывной разливке металлов и сплавов и вл етс усовершенствованием кристаллизатора, описанного в авт. св. № 500881.The invention relates to metallurgy, in particular, to the continuous casting of metals and alloys and is an improvement of the mold described in the ed. St. No. 500881.
По основному авт. св. № 500881 известен кристаллизатор, состо щий из корпуса, облицовки, полости дл охлаждающей жидкости и пластин из пористого материала, причем пластины установлены в полости дл охлаждающей жидкости и примыкают к облицовке кристаллизатора, а на поверхности пластин, обращенных к облицовке, выполнены каналы 1.According to the main author. St. No. 500881 is known a mold consisting of a body, a lining, a cavity for cooling fluid and plates of a porous material, the plates being installed in the cavity for coolant and adjacent to the lining of the mold, and channels 1 are made on the surface of the plates facing the lining.
Такой кристаллизатор обладает следующими недостатками:This mold has the following disadvantages:
необходимо больщое количество чистого жидкого охладител ;need a large amount of pure liquid cooler;
требуетс дополнительный конденсатор с отводом тепла, и, кроме того, применение проточной воды приводит к засорению капилл ров пористого материала при испарении воды, что приводит к нарушению равномерности теплоотбора и к ухудшению качества литого металла. В св зи с тем, что пористый материал имеет конкретную толщину, определ ющую предельную диффузионную инерцию дл передачи через себ жидкости, то это ограничивает быструю передачу большого количества воды дл данного участка облицовки, на котором произошли соответствующие изменени . При этом отвод паров, производимый ,по длинному каналу, нарушает отбор тепла на соседнем участке кристаллизатора .An additional condenser with heat removal is required, and, in addition, the use of running water leads to clogging of the capillaries of the porous material during the evaporation of water, which leads to a violation of the uniformity of heat extraction and deterioration of the quality of the cast metal. Due to the fact that the porous material has a specific thickness, which determines the limiting diffusion inertia for transferring through the liquid itself, this limits the rapid transfer of a large amount of water for a given lining area where the corresponding changes took place. In this case, the removal of vapors, produced by the long channel, violates the heat in the neighboring section of the mold.
Таким образом, в этом кристаллизаторе не осуществл етс или в минимальной степени проис.ходит регулирование интенсивности теплоотбора, что снижает качество литого металла.Thus, in this crystallizer the regulation of the intensity of heat extraction is not carried out or to a minimum extent, which reduces the quality of the cast metal.
Цель изобретени - повышение равиомерности и возможности регулировани интенсивности теплоотбора.The purpose of the invention is to increase raviomernosti and the possibility of regulating the intensity of heat extraction.
Это достигаетс тем, что кристал.изатор снабжен металлической оболочкой, в которой размещены пластины из пористого материала , а каналы заполнены испар ющейс жидкостью, например, фреоном, причем в пористых пластинах, в месте расположени каналов, выполнены пазы.This is achieved by the fact that the crystallizer is equipped with a metal sheath in which plates of porous material are placed, and the channels are filled with evaporating liquid, for example freon, and grooves are made in the porous plates at the location of the channels.
