Φ460 mm錐形輥穿孔機主傳動系統(tǒng)的改造

Revamp of Main Drive System of Φ460 mm Cone Type Piercer

摘要: Φ460 mm錐形輥穿孔機在生產(chǎn)大規(guī)格厚壁管尤其是P91、P92高壓鍋爐管時，主傳動系統(tǒng)作用在軋輥上的傳動力矩不能滿足要求。在保留原有主電機及電氣傳動裝置的前提下，采取適當增大主減速機減速比、更換萬向接軸的方案對穿孔機主傳動系統(tǒng)進行了改造。實踐證明：改造后的穿孔機主傳動系統(tǒng)提高了軋輥傳動力矩，滿足批量生產(chǎn)大規(guī)格高鋼級鋼管的需要。

Abstract: When producing the large-sized heavy-wall pipe especially the P91 or P92 high-pressure boiler pipe, the drive torque forcing on the roll by the main drive system of the Φ460 mm cone type piercer is insufficient.So while keeping the original main motors and electric drive devices, the main drive system of the piercer is revamped by appropriately increasing the reduction ratio of the main reducer and changing the universal shaft.Relevant actual operation practice shows that the revamped main drive system of the piercer has increased the drive torque of the roll and can meet the requirements of batch production of large-sized high-grade steel pipes.
