摘要： PROBLEM TO BE SOLVED: To provide a method and a device for turning a material at a suitable position in a furnace in order to achieve the decrease of uneven heat at the upper and the lower parts of a material to be heated while restraining the lowering of a furnace capacity and the increase of an equipment cost to the minimum in a walking hearth type heating furnace. SOLUTION: In the limited range of at least either one of a moving furnace hearth or a fixed furnace hearth in this walking hearth type heating furnace for a steel material, one pair or more of slopes 2 rolling down a round cross sectional material with the material dead wt., are formed and a furnace hearth in a range except the slopes is almost flattened. The shape of the slope is formed so that the length B2 in the slope horizontal direction of a side where the material steps over, is got over even in the shortest carrying pitch. Further, the length B1 of the slope on which the material rolls down, is made so as to obtain the necessary material rotation per one time. Then, the material is rolled down by laying the slope at each one time of carrying. In this way, even in the case that the interval of the material is not specially widened, the material is uniformly heated from the all surfaces in order according to the turning to decrease the uneven heat at the upper and the lower parts.

摘要： PROBLEM TO BE SOLVED: To change the spacings between materials to be heated in a suitable position in a walking hearth type heating furnace in order to minimize the degradation in capability at the time of opening the spacings between the materials so as to reduce the vertical heat deviation of the materials to be heated in this furnace. SOLUTION: A moving hearth is divided at several points in the longitudinal direction of the furnace. Horizontal transporting devices 17, 18 are discretely installed to the respective moving hearths 1, 2 to make the spacings between the adjacent materials 5 to be heated changeable by demarcating at their respective dividing parts 6. The hearth of the dividing parts of the moving hearths are composed of >=1 pair of rugged parts viewed flatly and are so formed as to prevent the disengagement of the fitting of the rugged parts in spite of a change in the distances between the respective moving hearths by transportation, by which the instantaneous fall of the materials to be heated into the spacings of the dividing parts 16 during the transportation is prevented. Further, in the case of the materials to be heated of a circular shape in section, the stationary hearth side is provided with a slope for rolling down the materials from the dividing parts to an extraction side. The lower part of the slope is provided with stoppers facing backward from the slope from which the materials fall.
