Cov yam ntxwv thiab siv cov xwm txheej ntawm qhov cub tawg

Quenching rauv yog lub cub tawg uas ua kom cua sov ua haujlwm ua ntej quenching. Kev tua hluav taws yog muab cov khoom ua haujlwm tso rau hauv lub tshuab ua kom sov thiab ua kom sov siab dua qhov tseem ceeb ntawm kev ntsuas kub thiab ua kom nws nyob ib ntus, tom qab ntawd nqa cov khoom ua haujlwm tawm ntawm lub cub tawg sai sai thiab muab tso rau hauv cov kua quenching (roj lossis dej) rau quenching. Qhov cua sov ntawm lub tshuab ua kom sov tuaj yeem yog hluav taws xob thiab roj, thiab ntsuas kub tau nrog lub thermocouple. Rau cov cua sov uas siv hluav taws xob, roj thiab roj ua kua, qhov kub tuaj yeem tswj tau thiab hloov kho los ntawm cov ntsuas.

Lub tshuab ua kom sov sov yog siv rau kev kho quenching ntawm extruded aluminium alloy yeeb nkab thiab bar profiles. Ua ntej quenching, cov khoom siv extruded yog rhuab uniformly, thiab qhov kub sib txawv yuav tsum tsawg dua ± 2.5 ℃; thaum lub caij tua, lub sijhawm hloov pauv yuav tsum luv dua, tsis pub ntev tshaj 15 vib nas this.

Yav dhau los, aluminium alloy extrusion khoom tau kho nrog nitrate (KNO3) da dej. Raws li qhov ntev ntawm aluminium alloy extruded cov khoom nce, qhov txheej txheem quenching tau raug tshem tawm. Lub tshuab ua kom sov ntsug feem ntau siv hauv tsev thiab txawv teb chaws, thiab lub pas dej quenching tau teeb tsa ncaj qha hauv qab lub cev rauv. Cov cua sov quenching no muaj cov yam ntxwv hauv qab no:

Fore Ua ntej quenching, cov khoom siv extruded tuaj yeem ua kom sov thiab ua kom sov sai;

② Cov khoom tuaj yeem muab tso rau hauv lub pas dej quenching hauv lub sijhawm luv;

T Nws tuaj yeem zam kev khoov thiab torsion deformation ntawm cov khoom lag luam extruded vim nws tus kheej qhov hnyav thiab cua sov, uas muaj txiaj ntsig zoo los tswj cov khoom ntawm cov khoom;

④ Cov khoom siv dag zog ntawm cov khoom siv extruded tom qab quenching yog ib yam.

Lub tshuab ua kom sov ntsug tsim los ntawm Non-ferrous Metal Processing Design thiab Research Institute tuaj yeem siv rau kev kho quenching ntawm aluminium alloy extruded cov khoom, tab sis qhov ntev ntawm cov khoom loj tsis tuaj yeem siab dua 8 meters. Nws tau siv tiag hauv cov ntoo me thiab nruab nrab cov txheej txheem txhuas, nrog rau kev ua haujlwm txhua xyoo ntawm 1,000 tons. Lub cub tawg tau muab faib ua tsib ntu cua sov, nrog lub zog cua sov siab tshaj plaws ntawm 300 kilowatts. Tom qab ntxiv cov cuab yeej pabcuam, tag nrho lub zog yog 424 kilowatts.

Cov mob uas siv

1. Siv sab hauv tsev.

2. Qhov ntsuas kub nyob ib puag ncig ntawm -5 ℃ -40 ℃.

3. Qhov nruab nrab txhua hli txheeb ze cov av ntawm thaj chaw siv tsis tshaj 85%, thiab qhov nruab nrab qhov kub nruab nrab tsis tshaj 30 ℃.

4. Tsis muaj cov hmoov av, cov pa tawg lossis cov pa tawg uas tuaj yeem ua rau hlau puas tsuaj thiab rwb thaiv tsev.

5. Tsis pom kev tshee lossis pob.
