鋼管在線水淬熱處理工藝

On-line Heat Treatment Process for Steel Pipe with Water Quenching

摘要: 介紹了天津市無(wú)縫鋼管廠運(yùn)用鍛造熱處理工藝?yán)碚摷肮に嚹M試驗(yàn),在現(xiàn)有的熱軋管生產(chǎn)線上實(shí)施在線內(nèi)外噴水淬火和離線回火的調(diào)質(zhì)工藝生產(chǎn)N80鋼級(jí)光套管的情況。生產(chǎn)實(shí)踐證明,在大生產(chǎn)模式的條件下實(shí)施該調(diào)質(zhì)工藝,鋼管的綜合力學(xué)性能穩(wěn)定,達(dá)到了預(yù)期效果。該工藝也是一種節(jié)能增效的工藝。

Abstract: Described is the heat treatment of the N80 black casing by means of the on-line internal-external water spray quenching process and the off-line temper process on the hot rolling production line in Tianjin Municipal Seamless Steel Tube Plant based on the application of the forging heat treatment process theory and the relevant process simulation tests.The operation practice proves the quenching and tempering process is capable of ensuring the consistence of the overall mechanical properties thus meeting the expected targets in the massive production of the N80 casings.Moreover the said heat treatment process is also an energy saving one.
