The invention relates to a method for producing an expanded granulate from sand grain-shaped mineral material (1) with a propellant, wherein the material (1) is fed into a vertically upright furnace (2) from above and said material (1) falls along a drop section (4) through multiple heating zones (5) in a furnace shaft (3) of the furnace (2), wherein each heating zone (5) is heatable using at least one independently controllable heating element (6), and the material (1) is heated to a critical temperature at which the surfaces (7) of the sand grains (15) plasticize and the sand grains (15) are expanded by the propellant. In order to enable setting a closed surface of the expanded granulate in a purposeful fashion, it is provided in accordance with the invention that upon detection of a first reduction in the temperature of the material (1) between two successive positions (9) along the drop section (4) the heating elements (6) are controlled along the remaining drop section (4) depending on the critical temperature. |

The invention relates to an installation for melting pig-iron comprising a cupola furnace, a combustion chamber burning the waste gases leaving this cupola furnace. This installation comprises furthermore a heat exchanger between the flue gases leaving this combustion chamber and a thermodynamic fluid driving at least one rotary machine coupled to at least one electric generator, a superheating furnace for the pig-iron in the liquid state disposed between the cupola furnace and a casting station. This superheating furnace is supplied by said electric generator, and switching means for diverting a part of the electric energy of the electric generator towards user means, which permits, by simply adjusting the proportion of coke in the charge of the cupola furnace, to regulate the superheating temperature of the pig-iron leaving the cupola furnace to a value such that there is obtained a better overall economy derived, on the one hand, from the economy in the consumption of coke and, on the other hand, from the production of electric energy for other user means. |

Combustion gases are generated in the liquid fuel combustion chambers provided on the middle shell of a cupola and blasted on the red-hot coke which is supplied automatically below said combustion chambers, to generate gas mixtures consisting of CO, H2 and N2 by water gas reaction and reducing reaction. These gas mixtures can be used as useful heat sources. By this process, the steam which has been so far regarded as a taboo in cupola operations can advantageously be utilized as hot gas so that cast iron of superior quality may be produced with better yields.

Metal bodies such as billets and blooms are reheated for rolling in a metal-refining operation having a blast furnace by first heating the top gas of the blast furnace to at least 800.degree. C. by means of a plasma torch, then, before the gas has cooled appreciably, burning the heated top gas in a preheating chamber. The metal bodies are exposed in the preheating chamber to the heat of the burning and heated top gas. The heated top gas is mixed with combustion-inducing gas to burn it. Before it is mixed with the heated top gas it is preheated by heat exchange with combustion-product gas withdrawn from the preheating chamber. In this manner it is possible to raise the temperature of this combustion-inducing gas to at least 600.degree. C., so that the burners firing the preheating chamber burn clean. In addition much of the heat of the process is recovered, again reducing energy costs for the system. |
