Abstract

The furnace for melting metals comprises a lined casing (1), a crucible(2) and a partition (3) which subdivides the crucible (2) into a melting chamber (4) and a collecting chamber (5), which chambers are connected therebetween. An intermediate capacity (7), which is provided with a latticed bottom (10) and with an opening for charging the furnace, and an outlet pump-heater (8), of which metal-conveying conduit is inserted into said intermediate capacity (7), are arranged in the melting chamber (4). Pumps for casting the metal are fabricated as pumps-heaters and are mounted in the collecting chamber (5).

The high performance of the furnace eliminates the need for melting and heating, which eliminates the pressure and temperature. On the one hand, this reduces the non-returning process of the metal, and on the other hand, it prevents the load of the atmosphere. The latter is especially important for casting metals, which have toxic steams, such as lead. At a low temperature, there is a significant decrease in the waste of metal due to the reduction of the reduced consumption of oxygen. If this is the case, the loss of heat in the furnace and the lower temperature must be avoided, which will result in less energy consumption.

The furnace offers further protection, except that the temperature in the furnace is slightly higher than that

After a good day, the alloy, partly cool, is empty in the melting chamber. In general, the temperature in the intermediate capacitance has been reduced so that a small amount of heat is avoided in the cavalry chamber. The desired temperature of the hot melt and when filling the furnace is achieved due to the additional heating of the hot melt and the charge is heated, it is installed. 15 аче As a part of the heating pumps, any hard pumps can be used, for example, a magnet-hydraulic pump (type universal heating)

The lower part of the temperature in the main part is disposed of by the need to reduce the cost of the metal in the railway. More conveniently, the temperature is reduced by the intensive oxidation of alloy, as well as by an increase in the amount of metal in the atmosphere. Experimentally, it was found that the temperature of the alloy was higher, which increased by 20%, the melting point was 5–7 times lower, and the temperature was 150 ° C.
