Abstract: PURPOSE:To reduce the abnormal erosion of a refractory material at the corner of a hearth, by analyzing the fluidization and transfer of a molten body in a pool for molten pig iron on the hearth during constructing the blast furnace to obtain the condition to suppress an erosion amount, and constructing the hearth. CONSTITUTION:In determining the position of a hearth during constructing the hearth of a blast furnace, the distributions of velocity and temp. in the spontaneous convection of pig iron in a pool 13 for molten pig iron derived from cooling it with a side wall are calculated using a model of turbulence. Using the experimental formula of melting velocity or the analogy between the transfers of heat and substance on the basis of said calculation result, the erosion amount of a refractory material 12 at each part of the hearth is calculated to estimate the condition of erosion at the hearth. By these calculating methods, the erosion line of the refractory material is estimated on the assumption that the erosion of the refractory material at the corner 5 of the hearth is caused by the spontaneous convection of the molten pig iron 13 in the vicinity of the furnace wall derived from the withdrawn of heat through the side wall part of the hearth. Thus, the condition to suppress the erosion amount is determined to construct the hearth.

Filed: 1987-04-21
Abstract: PURPOSE:To improve S/N characteristic of a semiconductor laser without rely ing upon the variation in a returning light ratio by forming a periodic structure for selectively feeding back only a light of wavelength used by diffracting a light generated in an active layer at the upper or lower side of the layer of a laser which is self-oscillated.
