A MELTING FURNACE

A melting furnace comprising lateral walls, furnace bottom, furnace pool, opening for loading the raw stock into the furnace, opening for discharge of combustion products, opening for supplying the melt for manufacture, threshold in the furnace bottom, zone for preparing the melt, zone of manufacturing the melt, recuperator, connected to the opening for discharge of combustion products, burners connected to the recuperator. The furnace additionally has the housing being tightly adjacent to the outer surface of walls, bottom and furnace arch, made with double walls mounted at the distance one from another, at that void adjacent to the lateral wall having the opening for loading the raw stock into the furnace, is provided with a fitting for intake of air from the blow device, and space of this void is connected to the void of housing adjacent to the outer surface of furnace bottom, which is connected to the voids of housing adjacent to the lateral walls of furnace, which are connected to the void of housing being adjacent to the outer surface of the furnace arch. Voids of housing being adjacent to vertical furnace walls are divided by partitions into reciprocally isolated ports, and void of housing being adjacent to the outer surface of arch has fitting for discharge of air by which it is connected to recuperator which is connected to pipeline with burners, at that combustion space in front of the opening for discharge of combustion products has additionally transverse partition being tightly adjacent to the inner surface of the arch and crosses the furnace combustion space under the arch below the level of burners exit to the combustion space. Плавильная печь, которая включает боковые стенки, дно печи, свод, бассейн печи, отверстие загрузки печи сырьем, отверстие выхода продуктов горения, отверстие выдачи расплава на выработку, порог в дне печи, зону приготовления расплава, зону выработки расплава, рекуператор, соединенное с отверстием выхода продуктов горения, горелки, соединенные с рекуператором. Печь дополнительно оснащена кожухом, который плотно прилегает к внешней поверхности стенок, дна и свода печи, выполненным с двойными стенками, смонтированными на расстоянии одна от другой, при этом пустота, которая примыкает к боковой стенке, обеспеченной отверстием загрузки печи сырьем, обеспечена патрубком приема воздуха от дутьевого устройства, а пространство этой пустоты соединено с пустотой кожуха, который примыкает к внешней поверхности дна печи, которая со
