Ib txoj hauv kev los tiv thaiv decarburization ntawm cov khoom siv hlau suav nrog thov kev sib xyaw ntawm SiC hmoov thiab nws yog xim hlau Al hmoov rau ntawm cov khoom hlau , ntxiv kev siv cov oxidation inhibitor ntawm qhov ntawd, thiab cua sov yog li ntawd. coated steel khoom, thiaj li muab 30 mus rau 500 g / m 2 SiC ntawm cov khoom hlau.
Yuav txo qis decarburization li cas?
Qee zaum, qhov kev puas tsuaj ua los ntawm decarburization tuaj yeem ua undone ntawm cov pa roj rov qab. Qhov no suav nrog muab ib feem rov qab rau hauv lub qhov cub nrog cov cua calibrated los hloov cov pa roj carbon monoxide uas yav tas los kos tawm.
Dab tsi ua rau decarburization ntawm steel?
Decarburization tshwm sim thaum cov hlau tau rhuab mus rau qhov kub ntawm 700 ° C lossis siab dua thaum cov pa roj carbon hauv cov hlau ua rau cov pa roj carbon monoxide lossis hydrogen. Kev tshem tawm cov pa roj carbon tshem tawm cov txheej txheem nyuaj carbide ua rau cov hlau softening, feem ntau ntawm cov chaw uas muaj kev sib cuag nrog cov roj decarburizing.
Yuav ua li cas thiaj tiv thaiv cov hlau tsis muaj cua sov?
Tempering cov hlau txoj cai tom qab cov txheej txheem hardening thiab ua tiav qhov kev hloov pauv nrog kev kho mob tuaj yeem pab tiv thaiv kom txias tawg. Tiv thaiv cov teeb meem kev kho cua sov los ntawm kev siv cov tswv yim no: lub tshuab nqus tsev vacuum, tsim kom muaj zog, quenching, tempering thiab molten ntsev.
Koj tiv thaiv kev kho cua sov li cas?
Txhawm rau tiv thaiv kev ntsuas thiab decarburization,kev saib xyuas yog coj mus rau siv cov txheej txheej txheej ntawm cov khoom siv. Cov txheej kuj tseem txo cov decarburization ntawm cov pob zeb thiab cov ingots thaum lub sij hawm kub-forging thiab kub dov. Thaum tshav kub kub hloov ntawm qhov nruab nrab cua sov mus rau cov hlau tsis cuam tshuam los ntawm txheej.
