Taw qhia txog hom hluav taws xob rauv taws

Hluav taws xob qhov cub
Lub tshuab hluav taws xob tuaj yeem siv cov khoom siv hlau lossis cov khoom tsis yog xim hlau los tsim cov cua sov. Nws cov qauv yooj yim thiab ntau yam kev siv yog nws cov yam ntxwv tseem ceeb. Lawv tuaj yeem siv dav hauv annealing, normalization, quenching, tempering, carburizing, thiab carburizing thiab nitriding. Lub ntsiab hlau hluav taws xob hluav taws xob muaj xws li Ni-Cr hluav taws xob kub xov hlau (feem ntau, mus txog 1200 degree), Mo-Si alloys, thiab cov hlau ntshiab xws li W thiab Mo; Cov khoom siv hluav taws xob tsis yog xim hlau muaj xws li SiC (feem ntau, uas tuaj yeem ua kom sov txog 1600 degree), LaCrO3, thiab graphite rods (uas tuaj yeem ua kom sov txog 2000 degree hauv lub tshuab nqus tsev lossis tiv thaiv huab cua).
qhov zoo:
1) Nws yog qhov yooj yim dua kom tau txais qhov kub thiab txias piv rau cov roj cua sov.
2) Cov khoom tuaj yeem ua kom sov los ntawm sab hauv.
3) Yooj yim rau siv hauv cov cua sov cua sov thiab lub tshuab nqus tsev vacuum.
4) Lub tshuab hluav taws xob hluav taws xob tsis muaj qhov hluav taws xob poob los ntawm lub tshuab hluav taws xob, yog li nws muaj thermal efficiency siab.
5) Yooj yim los tswj qhov kub thiab txias, yooj yim rau kev tswj chaw taws teeb thiab kev kho kom zoo.
6) Muaj peev xwm ua cua sov sai.
7) Kev ua haujlwm zoo, tsis muaj kuab paug ib puag ncig.
Qhov tsis zoo:
1) Tus nqi ntawm cov khoom siv hluav taws xob yuav tsum tau nce ntxiv.
2) Cov nqi hluav taws xob siab.
3) Thaum cov cua kub tsis kam kub siab tshaj 1000 degree, cov ntaub ntawv refractory yuav ua hluav taws xob, thiab yuav tsum tau them nyiaj rau cov teeb meem rwb thaiv tsev.
