Qhov txawv ntawmKub dovthiabCov Yeeb Nkab Hlau Txias?
Txawm hais tias ob qho khoom siv rau hauv kev tsim hlau, qhov sib txawv tseem ceeb los ntawm cov txheej txheem tsim.
Hauv kev tsim cov raj hlau ua vaj tse, "kub dov" feem ntau yog txuam nrog cov seem hollow kub tiav, thaum ntau lub raj plaub fab thiab plaub fab yog tsim los ntawm kev tsim txias los ntawm cov hlau dov kub.
Txoj kev tsim khoom ncaj qha cuam tshuam rau qhov xwm txheej ntawm lub raj, qhov tseeb ntawm qhov ntev, kev ntxhov siab seem, thiab kev ua haujlwm zaum kawg.
Cov Txheej Txheem Tsim Khoom: Yuav Ua Li Cas Cov Raj Kub Thiab Cov Raj Txias Uas Tsim Los
Cov Hlau Kub Dov
Cov kav hlau kub dov yog tsim tawm ntawm qhov kub siab dua qhov kub recrystallization hlau, feem ntau siab dua 926 ° C.
Thaum kub siab, hlau ua rau mos dua thiab yooj yim dua rau deform, ua rau cov chaw tsim khoom tsim cov ntu loj nrog kev ruaj khov zoo.
Tom qab ua tiav lawm, cov hlau yuav txias ntuj ntawm qhov kub thiab txias hauv chav tsev. Cov txheej txheem txias qeeb pab txo cov kev ntxhov siab seem thiab muab kev ywj pheej zoo thiab kev ua haujlwm tsim khoom.
Kev Tsim Khoom Txheej Txheem
Cov Yeeb Nkab Hlau Txias

Rau cov raj welded square thiab rectangular, cov txheej txheem ib txwm yog:
Qhov Tiav Ntawm Qhov Chaw Thiab Qhov Ntsuas Qhov Tseeb
Qhov Nto Nto
Kub dov hlau raj
Thaum lub sijhawm txias, qhov chaw hlau kub ua rau cov pa oxygen thiab tsim cov hlau oxide.
Qhov no tsim cov txheej txheem oxide grey tsaus, feem ntau hu ua zeb nplai.
Cov yam ntxwv:
- Qhov chaw oxide tsaus nti
- Kev ntxhib me ntsis
- Yuav tsum tau npaj qhov chaw ua ntej txheej
Cov Yeeb Nkab Hlau Txias
Vim tias kev tsim khoom tshwm sim ntawm chav tsev kub, tsis muaj cov txheej txheem oxidation kub siab.
Cov yam ntxwv:
- Nto du
- Zoo dua qhov tsos
- Ntau qhov loj sib xws
Kev kam rau siab ntawm qhov ntev
Cov kav hlau kub dov feem ntau muaj kev kam rau siab dav dua vim tias kev txias txias tuaj yeem tsim kev hloov pauv ntawm qhov ntev.
Cov raj xa dej txias ua tiav qhov kev kam rau siab dua vim tias lawv tau ua tiav los ntawm cov menyuam thiab cov tuag precision.
Kev Sib Piv Txog Cov Khoom Siv Kho Tshuab
