摘要： In the production of steel from pig iron melted and refined in a vessel, the pig iron is preheated in two phases. In the first preheating phase, the cold pig iron and hot gases recovered from the melting and refining vessel are moved simultaneously through a first and higher rotary tubular furnace whose lower open end is in communication with an upper open end of a second and lower rotary tubular furnace constituting a second preheating phase. The second furnace is heated from the outside to regulate the temperature of the pig iron to a desired value before it is introduced into the vessel from the second furnace.

摘要： Installation according to the invention comprising a desilication and dephosphorization stage (A), followed by a decarburization stage and in which the pig iron to be pre-smelted is intended to form a bath whose free surface is maintained at a predetermined level (N.sub.1).The dephosphorization comprises a reactor (1) comprising means (5, 6, 8) respectively for introducing the pig iron to be pre-smelted, for adding desilication and dephosphorization agents, and for creating an oxidizing atmosphere, as well as rabbling means (9). It also comprises a decanter (2) separated from the reactor (1) by a partition (3) having an opening (4) below the level (N.sub.1) and whose upper end is above the latter. The decanter comprises an immersed outlet opening (10) connected to the decarburization stage and an overflow (12) for evacuating the slag. The slag formed in the reactor (1) flows out in the decanter (2), overflows above the partition (3), and moves toward the overflow (12) which evacuated it.
摘要翻译：根据本发明的包括脱磷和脱磷阶段（A）的装置，随后是脱碳阶段，其中预先熔炼的生铁旨在形成其自由表面保持在预定水平（N1）的浴。脱磷包括反应器（1），其包括分别用于引入待熔炼的生铁，用于添加脱硅和脱磷剂并用于产生氧化气氛的装置（5,6,8）以及冲洗装置（9 ）。它还包括通过具有在水平面（N1）下方的开口（4）并且其上端在其上方的开口（4）与反应器（1）分离的滗析器（2）。滗析器包括连接到脱碳阶段的浸没式出口（10）和用于排出炉渣的溢流（12）。在反应器（1）中形成的炉渣在滗析器（2）中流出，溢出在分隔件（3）的上方，并向排出的溢流器（12）移动。
