Huab cua-resistant steel daim hlau yog tsim los ntawm kev ntxiv cov kab xws li phosphorus, npib tsib xee, thiab tooj liab rau cov hlau zoo tib yam thaum lub sij hawm smelting. Ib qhov ntom ntom, tiv thaiv zaj duab xis yog tsim rau saum npoo ntawm cov hlau, uas cuam tshuam kev sib kis ntxiv ntawm xeb, yog li tiv thaiv cov ntaub ntawv hauv qab kom qeeb corrosion. Huab cua steel vaj huam sib luag muaj qhov liab qab sab nrauv thiab tiv thaiv corrosion tsis tas siv cov txheej ntxiv. Nws yog ib puag ncig tus phooj ywg vim nws tsis ua qias neeg ib puag ncig.
Cov txheej txheem ntau lawm ntawm huab cua steel daim hlau: Weathering steel feem ntau smelted nyob rau hauv lub cub tawg, nrog rau converter, hluav taws xob rauv microalloying, argon tshuab thiab refining, qis superheat nruam casting, tsawg ntiaj teb hlau noj, tswj dov thiab tswj txias. Thaum lub sij hawm smelting, seem hlau yog ntxiv rau hauv lub cub tawg ua ke nrog tus nqi thiab smelted raws li cov txheej txheem pa. Tom qab cov hlau raug tshem tawm, deoxidizer thiab alloy ntxiv. Tom qab tshuab argon rau hauv cov hlau molten, cov hlau yog cam khwb cia tam sim ntawd, thiab cov hlau molten hloov kho los ntawm argon roj kub yog nrum los ntawm lub tshuab nruam nruam. phaj. Vim tias qhov sib ntxiv ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb rau cov hlau, cov huab cua steel yog purified thiab cov ntsiab lus suav nrog txo qis heev.
Tuam Tshoj tau siv huab cua-resistant steel daim hlau txij li xyoo 1960. Txawm hais tias nws tau siv rau lub sijhawm ntev, kev tshawb fawb thiab kev tsim kho thiab tsim cov phiaj xwm huab cua-resistant steel hauv Suav teb tsis poob qab. Nrog rau txoj kev loj hlob sai ntawm lub teb chaws kev lag luam, daim ntawv thov ntawm huab cua-resistant steel daim hlau tau raug coj los ua ke los ntawm cov tuam tsev hauv tsev. Kev xyuam xim rau kev txhim kho thiab kho dua tshiab ntawm huab cua-resistant steel daim hlau yog qhov ua tau zoo thiab muaj kev cuam tshuam tseem ceeb rau kev txhim kho cov txheej txheem ntawm kev lag luam steel.
