17、2主材（含焊材）無論是領(lǐng)用、發(fā)放，倉管都必須核對(duì)材料的品種、規(guī)格、數(shù)量是否與計(jì)劃單相同。2、下料2.1下料前的準(zhǔn)備工作2.1.1下料人員在下料前要熟悉本工序的技術(shù)規(guī)范、標(biāo)準(zhǔn)及相關(guān)要求。2.1.2按照公司材料領(lǐng)用程序到倉庫辦理領(lǐng)用手續(xù)。2.1.3火焰下料在上料前要進(jìn)行三查：1）查所下材料的規(guī)格、材質(zhì)、尺寸是否與圖紙或排版圖相符；2）查燃?xì)?、氧氣的壓力、存量是否能滿足下料的需求；3）查割嘴是否與所下料的規(guī)格相對(duì)應(yīng)；2.1.4剪切下料要檢查剪

18、板機(jī)上下刀口間隙是否與所下材料板厚相符。2.2下料2.2.1火焰下料在下料前要根據(jù)不同板厚調(diào)整燃?xì)?、氧氣的壓力以及更換不同的割嘴。其參考數(shù)據(jù)見下表：切割氧孔徑切割厚度切割速度氣體壓力MPa割嘴號(hào)mmmmmmmin氧氣丙烷氣00.75～10600～4500.2～0.3＞0.0310.910～20480～3800.2～0.3＞0.0321.230～35400～3200.3～0.4＞0.0331.536～60350～2800.3～0.4＞0.
