Description
Известные в промышленной практике индукционные печи с тигл ми и подовыми камн ми, изготовленнымн из огнеупорных масс, примен емые дл плавки легких цветных металлов и сплавов, быстро выход т из стро , вследствие зарастани футеровки окислами и шлаками и от воздействи солевых расплавов. Зарастание футеровки вызывает необходимость частой механической очистки. Кроме того, футеровочные огнеупорные массы требуют дополнительной сушки и частичного обжига.Known in industrial practice, induction furnaces with crucibles and hearths, made of refractory masses, used to melt light non-ferrous metals and alloys, quickly deteriorate due to the overgrowing of the lining with oxides and slags and from the effect of salt melts. Lining overgrowth necessitates frequent mechanical cleaning. In addition, refractory lining masses require additional drying and partial roasting.
Описываемые печи дл плавки легких цветных металлов и сплавов, как показала эксплуатаци их, не имеют этих недостатков.The described furnaces for smelting light non-ferrous metals and alloys, as shown by their operation, do not have these disadvantages.
Отличительной особенностью печи вл етс то, что ее плавильную камеру {тигель или подовый камень) изготавливают из воздушпо-твердегош ,его материала - жароупорного бетона - следуюш,его состава: 20-25% магнезита, 15-20% жидкого стекла, 1,5-2,0% кремне-фтористого натри , 20-25% шамотного песка и 30-35% шамотного шебн .A distinctive feature of the furnace is that its melting chamber (crucible or hearth stone) is made of air-solids, its material - heat-resistant concrete is next, its composition: 20-25% magnesite, 15-20% liquid glass, 1.5 -2.0% silica-fluoride, 20-25% chamotte sand and 30-35% chamotte shebn.
Предмет изобретени Subject invention
Печь дл плавки легких цветных металлов и сплавов с электрическим обогревом, отличающа с тем, что, с целью увеличени срока службы футеровки печи, ее плавильна камера (тигель или иодовый камень ) выполнена из жаропрочного бетона, содержашего 20-25% магнезита , 15-20% ЖИдкого стекла, 1,5-2,0% кремпе-фтористого натри , 20-25% шамотного песка и 30-35% шамотного шебн .A furnace for melting light non-ferrous metals and alloys with electric heating, characterized in that, in order to increase the service life of the furnace lining, its melting chamber (crucible or iodine stone) is made of heat-resistant concrete containing 20-25% magnesite, 15-20 % Of living glass, 1.5-2.0% of creamy sodium fluoride, 20-25% of chamotte sand and 30-35% of chamotte shebn.
