A method for the time to be optimally circulate the bar in the manufacture of hot finish seamless steel pipe by a continuous steel tube method and apparatus

摘要

Apparatus for circulating optimally mandrel bar, additional drying for lubricants to be applied to the mandrel bar by the cases of (1) the mandrel bar lubricating station and (2) cooling table or mandrel bar for feed table I would roller table that is attached to the station and (3,4). Bar collateral circulation path of the other is provided on the upstream side of the standard bar circulation path consists of (11, 12) delivery two tables that operate redundantly said bar collateral circulation paths, the delivery table is no longer needed is coupled to the cooling table or the supply tables through the first roller table third roller or table (2) for delivering from the standard bar circulation path bars are not, the third roller table to the first It is either, or forming an extension of the roller table, if they are staggered in parallel thereto. Furthermore, the fourth roller table for delivery to the standard bar circulation path through the intermediate buffer or to receive the mandrel bar (9) is provided in parallel with the first roller table on the other side of the delivery table have.
