摘要： In this invention, the smelting reduction operation can be carried out in a high efficiency by charging a carbonaceous material in such an amount that total surface area is not less than 60 m.sup.2 per 1 ton of slag weight. Carbon substance finely particulating through thermal crumbling under a high-temperature atmosphere inside the vessel is used as the carbonaceous material, whereby it is possible to stably conduct the smelting reduction while controlling the scattering of the carbonaceous material, and also the erosion, particularly locally erosion of refractory in the smelting reduction furnace, which was a serious problem in the conventional technique, can considerably be decreased to largely prolong the service life of refractory.

摘要： A process for continuous casting of ultra low carbon aluminum killed steel, characterized in that the steel contains 6-20 ppm of calcium, less than 0.01 wt % of sulfur, and less than 30 ppm of oxygen, the molten steel superheat temperature in the tundish is higher than 16.degree. C., and the average flow rate of molten steel is greater than 1.2 m/sec in the straight part of the nozzle. This process prevents rusting and eliminates the necessity of blowing a gas into the immersion nozzle and hence prevents the swelling of cold rolled sheets.

摘要： A side wall construction for a continuous belt caster includes a metallic side wall body and a refractory layer attached on the central portion of the side wall body. The metallic side wall body has side edge portion extending substantially in flush with the the surface of the refractory layer. The refractory layer is formed with a center projection of essentially triangular cross-section. The height of the peak of the projection is gradually decreased toward downstream of transfer direction of the liquidus and solidus metal. On the other hand, it may be possible to formulate the refractory layer as double layer construction of a heat insulating refractory layer and a wear-resistantive refractory layer.

摘要： A continuous casting process introduces the factor of rate temperature change for detecting break out in the cast metal. Introduction of rate of temperature change as a parameter representative of the cast metal condition is successful for avoiding the influence of variation of the casting condition, fluctuation of the powder to be introduced between the casting mold wall and the cast metal, casting speed and so forth. For achieving accurate detection of break out of the cast metal by introducing the temperature change factor, casting mold wall temperatures are measured at various measuring points which are circumferentially aligned. Rates of temperature change at each measuring point and average rate of temperature change of all measuring points are derived and compared for making judgement of possible break out when the difference of the rate of temperature change at each measuring point and the average rate of temperature change becomes greater than a predetermined value.
