    12Cr1MoVG大直徑高壓鍋爐管適應(yīng)新標(biāo)準(zhǔn)的工藝技術(shù)優(yōu)化

    Process Optimization of 12Cr1MoVG Big Diameter High Pressure Boiler Pipe to Fit for a New Standard

    • 摘要: 介紹按GB 5310—2008標(biāo)準(zhǔn)生產(chǎn)的12Cr1MoVG大直徑高壓鍋爐管的熱處理生產(chǎn)工藝數(shù)據(jù)，對(duì)全壁厚大直徑高壓鍋爐管試樣進(jìn)行熱處理正交試驗(yàn)，分析影響12Cr1MoVG大直徑高壓鍋爐管硬度指標(biāo)的因素。分析認(rèn)為：新版GB/T 5310—2017將表面硬度列入驗(yàn)收條件，大大增加了熱處理難度；影響表面硬度的主次因素依次為回火溫度、回火保溫時(shí)間、淬火冷卻方式、修磨深度；應(yīng)根據(jù)實(shí)際生產(chǎn)條件，對(duì)生產(chǎn)數(shù)據(jù)進(jìn)行統(tǒng)計(jì)分析，找出規(guī)律，不斷優(yōu)化熱處理參數(shù)。

       

      Abstract: The heat treatment process data for 12Cr1MoVG big diameter high pressure boiler pipe being manufactured according to GB 5310-2008 are introduced in the paper.An orthogonal heat treatment test is carried out on a full-size sample of a big diameter high pressure boiler pipe to analyze factors affecting the hardness of 12Cr1MoVG big diameter high pressure boiler pipe.The analysis shows the following conclusions.Since surface hardness is defined in GB/T 5310-2017 as an acceptance criteria,more difficulties are put on the heat treatment process.The factors affecting surface hardness are listed in order of importance as tempering temperature,tempering holding time,quenching cooling method and repair depth.It is recommended to,according to real production conditions,do statistical analysis on production data,find the pattern and keep optimizing the heat treatment parameters.
