摘要： A continuously cast strand is cut into elongated billets having ends and the billets are run through a rolling stand. after cutting the strand into billets and before rolling the billets one of the billets is engaged in the rolling stand and a trailing end of the one billet and a leading end of another billet are enclosed in a mold with the ends longitudinally spaced. This space between the ends is filled with molten metal in contact with the ends of the billets and the molten metal is hardened to interconnect the billet ends. Then the mold is removed from around the billet ends. The molten metal is of substantially the same composition as the billets. Furthermore the one billet is advanced in a travel direction by means of the stand and the mold and the other billet are advanced synchronously with the one billet after enclosing the billet ends in the mold. The mold is removed from the billet ends before the hardened metal between the billet ends enters the rolling stand.

摘要： A method of coiling or placing bar steel or wire in coils, wherein the rolling stock is reeled from rolling heat in a basket or is placed by a coiler in the form of coils onto a conveyor and is collected at the end of the conveyor over a mandrel into a coil, wherein the rolling stock is cooled during coiling and the rolling stock is further cooled after the coiling process or the formation of coils. Cooling of the rolling stock from rolling heat prior to coiling into the transformation range characterized by the Ar.sub.3 line or Ar.sub.1 line of the transformation time-temperature diagram corresponding to the type of steel to be cooled is extended, such that, depending on the type of steel, the rolling stock is transformed immediately after cooling prior to, during or after coiling, uniformly over the entire length and entire cross-section thereof essentially isothermally from the austenite phase into the ferrite phase or pearlite phase and, as required, into the bainite phase.

摘要： A method of rolling steel sections, particularly in a universal section mill, wherein X-shape rolling and H-shape rolling are carried out alternatingly and specifically directed cooling of the steel section is carried out during rolling. During roughing rolling in a X-shaped groove a cooling water channel is formed at each side of the steel section at the connecting locations between web and flange. The roll cooling water flowing off from the H-shaped rolls is concentrated in the cooling water channels. An additional quantity of water may be added either without pressure or in the form of spray water to the concentrated roll cooling water.
摘要翻译： 在轧制过程中，进行轧制钢部分的方法，特别是在通用型轧机中进行X形轧制和H型轧制，以便在轧制过程中进行交替和特定的冷却。 在X形槽中进行粗轧时，在钢板和钢板之间的连接位置处，在钢板的两侧形成冷却水通道。 从H型辊流出的辊冷却水集中在冷却水通道中。 可以向压缩冷却水中添加额外量的无压力或喷雾形式的水。
