Abstract
The evaluation shows that the temperatures in the car-type furnace and the crusher jackets became considerably more even following conversion of the car-type furnace to natural gas. Test Jacket 2 - placed in one corner of the bogie hearth - still heats unevenly, however. This is caused by inleaked air infiltrating through the lifting door and the fact that the burners are at the same level as the crusher jackets. Owing to the effect of one burner on the flame, the temperature in test jacket 2 rises rapidly at the measuring points nearest the burner when this is ignited. Test jacket 1 at the centre of the bogie hearth is heated uniformly but somewhat more slowly than test jacket 2 in the natural gas firing experiment. The converse applied to the rate of heating in the oil firing experiment. In the case of both test jackets, temperature differences remain when the jackets are removed from the furnace. For test jacket 1 at the centre of the bogie hearth, the differences are small, while for test jacket 2 the gradients are approx. 60 deg. C on completion of the heat treatment cycle in the natural gas firing experiment. Productivity did not
