Cov Cheebtsam yauv ua cov txheej txheem ntawm kev sib tsoo thiab tua hluav taws tom ntej, thiab tom qab ntawd melting siv lub tshuab hluav taws xob arc.
Cov kev daws tiav lawm yog cov khoom ntawm qhov kev rho tawm thiab yog tom qab tawg thiab txheeb.
Qhov ntsuas qhov tsawg kawg rau kev tsim cov calcium carbide yog 1619 degree. Feem ntau, cov txheej txheem ntau lawm yog nqa tawm ntawm qhov kub ntawm 1900-1950 degree. Cov txheej txheem ntawm kev nce qib kub yuav ua rau cov decomposition ntawm calcium carbide rau hlau thiab carbon.
Cov txheej txheem ntawm calcium carbide tsim tau tuaj yeem luam tau siv cov hluav taws xob me me arc thiab lub zog hluav taws xob.
Cov cuab yeej ua ntej muaj cov kab ke ntoo khaub ncaws crucite lossis cov pa hluav taws xob, uas tau hloov kho los ntawm kev tsim kev nyuaj siab thiab coke, uas tau ntsuas tawm hauv cov sib npaug sib npaug raws li lawv qhov hnyav. Nws yog paub tias kev ua kom haum zoo rau kev sib xyaw, yog li cov txheej txheem ntev li ib nrab ib teev txog thaum arc hlawv tawm. Qhov sib tov yog tom qab ntawd tso cai rau txias, ua rau muaj kev tsim ntawm ib qho alloy. Yog tias qhov kev sim ua tiav, cov alloy no yuav tsum muaj cov khoom me me ntawm carbide. Txhawm rau tshuaj xyuas qhov no, cov huab hwm coj tau muab tso rau hauv dej, thiab cov roj npuas ua rau muaj nyob hauv qhov ntsuas tsis pub dhau muaj dej.
Ib tug xov tooj ntawm cov yam ntxwv tuaj yeem txheeb tau tias cuam tshuam tus nqi ntawm kev tsim thiab cov yam ntxwv zoo ntawm cov khoom kawg, thiab muaj kev cuam tshuam nrog cov khoom noj. Nws tseem tsim nyog yuav tau coj mus rau hauv tus account lub cev - cov lus qhia ntawm cov cub hluav taws xob thiab ua tiav nrog cov theem ntawm cov txheej txheem thev naus laus zis. Txawm hais tias muaj niaj hnub no ntawm cov txheej txheem ntau lawm, kev tsim cov calcium carbide tseem muaj zog, xav tau cov chaw loj thiab kev nqis peev nyiaj txiag.
