The relations between the results calculated in Parts II and III for the model device and the basic melting characteristics (specific energy consumption and output) of a real melting tank furnace can be expressed by means of the model device. With real tank furnaces the, values of the fictive dead zones are high (0.7 - 0.8) and indicative of considerable reserves, especially as regards the course of flow, which mostly involves a large proportion of recycling melt. The reserves can be reduced above all by means of mathematical models of the melting zones. As indicated by the graphic representation of the cutting down of the reserves in Figs.1 and 2, an economic way is provided by raising the output of the melting zones while not decreasing the melting temperature. |
