摘要： Fe-Cr alloy billet manufacturing method according to the present invention, since the blooming is carried out with the high reduction rate surface of the steel strip covered with a scale layer of a large area rate as 70 % or more and without the descaling applied, can reduce the indentation and inclusion of the scale. Thereby, in the case of a billet for use in seamless steel pipes being manufactured from a steel strip of a Fe-Cr alloy, surface treatment before tube-making can be largely reduced. Thereby, when the Fe-Cr alloy billet is adopted in manufacturing seamless steel pipes, since even the Fe-Cr alloy steel pipe relatively hard to process can be manufactured at low manufacturing cost and efficiently, it can be widely applied in a field of manufacturing hot seamless steel pipes.
摘要翻译：根据本发明的Fe-Cr合金坯锭制造方法，由于用大面积率的鳞屑层覆盖的钢带的高还原率表面为70％以上而不施加除垢，可以减少刻度和包含尺度。因此，在由Fe-Cr合金钢带制造的无缝钢管中使用的坯料的情况下，可以大幅度地减少制管前的表面处理。因此，在制造无缝钢管时采用Fe-Cr合金钢坯，由于即使是相对难以加工的Fe-Cr合金钢管，也可以制造成本低，制造成本高，可广泛应用于制造领域热无缝钢管。

摘要： A continuous rolling method comprises the steps of: flash-butt welding a rear end of a preceding billet with a front end of a succeeding billet; grinding the welded portion to remove a burr on the welded portion; heating the continuous billet; and rolling the continuous billet through a series of rolling mills. The flash-butt welding step includes joining the rear end of the preceding billet with the front end of the succeeding billet by using the stationary welder (3) and joining the billets having at least double the length of the preceding billet by using the travelling welder (4). A continuous rolling apparatus comprises a stationary flash-butt welder (3), a travelling flash-butt welder (5), a travelling grinding machine (6), an induction heater (7) and a series of continuous rolling mills (8).

摘要： When rolling out a series of billets one billet (2B) at a time is ejected out of a billet furnace (1) towards a conveyor apparatus (6) which conveys the billet (2B) on towards a first mill stand (4) of a rolling mill train. To improve the throughput of billets, a sensor (3) is provided between the first mill stand (4) and the conveyor apparatus (6) close to the latter. The conveyor apparatus (6) initially has a conveying speed matched to the ejection speed of the billet (2B). The billet (2B) is conveyed at this speed until it is detected by the sensor (3), whereupon the conveying speed of the conveyor apparatus (6) is increased in dependence on signals provided by the sensor (3), and then finally is adjusted to a value which corresponds to the conveying speed of the rolls of the first mill stand (4).
摘要翻译：当轧制一系列坯料时，一个坯料（2B）一次从坯料炉（1）中排出到输送设备（6），输送设备（6）将坯料（2B）输送到第一轧机机架（4）上轧机列车为了提高坯料的生产量，传感器（3）设置在第一轧机机座（4）和接近后者的传送装置（6）之间。输送装置（6）最初具有与坯料（2B）的喷射速度相匹配的输送速度。坯料（2B）以这种速度被输送，直到由传感器（3）检测到，由此输送装置（6）的输送速度根据由传感器（3）提供的信号而增加，然后最终是调节到对应于第一轧机机架（4）的辊的传送速度的值。

摘要： A Fe-Cr alloy billet, characterized in that a high area % as high as 70 area % or more of the higher draft surface thereof is coated with a scale layer; a method for producing a Fe-Cr alloy billet wherein an ingot is subjected to blooming without de-scaling of the ingot. The Fe-Cr alloy billet allows the reduction of the thrust or enfoldment therein of scales and allows the significant reduction of the surface treatment prior to the manufacture of a tube in the production of a billet for a seamless tube. The employment of the Fe-Cr alloy billet for the production of a seamless tube allows the production of a Fe-Cr alloy steel tube being comparatively difficult to manufacture with a reduced cost with good efficiency, which leads to the widespread application thereof in the field of the production of a hot seamless steel tube.
