摘要： A method for treating a steel slab containing 2.5 to 4% Si to a temperature not lower than 1260.degree. C. in a continuous heating furnace of the walking-beam type, comprising; charging the slabs into the continuous heating furnace through its charge inlet, transferring the slabs by means of walking-beams in the furnace with the rear end of a preceding slab substantially contacting a front end of a subsequent slab under the condition that the contact time of the slab with fixed beams is not more than three times longer than the contact time of the slab with the transfer beams, and separating the adjacent slabs with a space sufficient to permit remelting of solidified slag adhered between the adjacent slabs approaching the extraction outlet of the furnace.

摘要： In a method for producing a cold-rolled steel sheet by continuously casting, hot-rolling, cold-rolling, and continuously annealing Al-killed steel, it is known to coil a hot-rolled strip at a coiling temperature of 630.degree. C. to 710.degree. C. so as to attain satisfactory precipitation of AlN in the hot-rolling step. When the direct-rolling of a continuously cast strand (DR method) is employed to produce a cold-rolled strip, it is impossible to attain satisfactory precipitation of AlN even by carrying out the known coiling method. The present invention is characterized in that an extremely high coiling temperature of at least 780.degree. C. is used to essentially prevent aging due to the precipitation of AlN, and, further, the carbon content of a continuously cast slab is 0.005% at the highest so as to essentially prevent the occurrence of orange peel. Heat conservation due to use of the DR method and excellent properties of the cold-rolled steel strip are simultaneously attained.
摘要翻译：在通过连续铸造，热轧，冷轧和连续退火Al镇静钢的冷轧钢板的制造方法中，已知在630℃的卷取温度下卷取热轧带材到710℃，以便在热轧步骤中获得令人满意的AlN的沉淀。当使用连续铸造线材（DR法）的直接轧制来制造冷轧带材时，即使采用已知的卷取方法也不可能获得令人满意的AlN的析出。本发明的特征在于，使用极高的至少780℃的卷取温度来基本上防止由于AlN的沉淀引起的老化，此外，连续铸造的板坯的碳含量最高为0.005％以便基本上防止橙皮的发生。同时获得使用DR法的热保存和冷轧钢带的优异性能。
