Cov lus qhia rau kev siv mica hluav taws xob cua sov coil:

Cov lus qhia rau kev siv mica hluav taws xob cua sov coil:

1. Cov kab hluav taws xob tau muab tso rau sab nraum cov cua sov txheej thiab txheej rwb thaiv tsev, thiab lub plhaub yuav tsum tau ua kom zoo hauv av;

2. Khaws rau hauv qhov chaw qhuav.

High resistivity tus nqi:

Hluav taws xob cua sov alloy cov ntaub ntawv yuav tsum xub muaj kuj siab resistivity. Lub tshuab hluav taws xob cua sov ua los ntawm cov khoom siv hluav taws xob muaj zog muaj kev hloov pauv hluav taws xob siab; qhov ntim ntawm cov hluav taws xob cua sov yog me me; cov khoom siv alloy raug cawm; high-power ceev cua sov tuaj yeem pom tau. Nws yog ib qho tseem ceeb tshwj xeeb tshaj yog thaum tsim hluav taws xob cua sov rau hluav taws xob nrog qhov kub thiab txias, lub zog siab thiab qhov me me.

Chav tsev kub resistivity ntawm feem ntau siv hluav taws xob cua sov alloys yog 1.00-1.60μΩ•m. Lub resistivity ntawm cov hlau complex aluminium alloy yog siab dua li ntawm cov nickel-chromium thiab nickel-chromium-hlau alloys. Chav tsev kub resistivity ntawm ib txwm hluav taws xob cua sov alloys yog teev nyob rau hauv Table 5-1. Cov tuam txhab sib txawv sib xyaw ua ke lawv cov qib alloy kom muab cov chav ntsuas kub tiv thaiv qhov tseem ceeb.

Kev siv tswv yim ntawm mica hluav taws xob cua sov coil:

1. Dav siv nyob rau hauv tsev hluav taws xob lub voj voog, xws li mov cookers, microwave ncu, hluav taws xob tua kab mob, tshuab ziab plaub hau, hluav taws xob irons, thiab lwm yam.

2. Nws yog dav siv los ua cua sov qhov chaw ntawm ntau lub tshuab lub voj voog, xws li kev txhaj tshuaj molding tshuab, tshuab luam ntawv, tshuab luam ntawv, fax tshuab, thiab lwm yam.

3. Ntau yam kev lag luam thiab kev ua liaj ua teb cua sov, xws li pwm cua sov, tshuab yas, thiab lwm yam khoom siv cua sov thiab ziab.

Cov nyhuv ntawm carburizing roj nruab nrab ntawm hluav taws xob cua sov alloy

Carburizing roj nruab nrab siv nyob rau hauv kev kho mob ntawm cov hlau yog ib tug muaj zog txo nruab nrab. Cov pa roj carbon kev koom tes tuaj yeem muab faib ua ob hom: endothermic thiab exothermic, thiab nws muaj pes tsawg leeg (%) yog raws li hauv qab no.

Gas hom H2 CO CO2 N2

Endothermic type 30~40 20~30 0.1~0.5 margin

Exothermic type 10~15 5~7 5~6 margin

Tsis tas li ntawd, nws kuj muaj activated carbon thiab methane.

Cov kev kho mob carburizing feem ntau yog 900 ~ 950 degree, thiab qhov kub ntawm qhov cua sov tuaj yeem ncav cuag 1000 ~ 1100 degree. Thaum carburizing, cov khoom cua sov yuav tsum tau muab cais tawm ntawm cov roj nruab nrab, txwv tsis pub, cov cua sov yuav raug corroded.

Thaum cov khoom los yog hlau nrog cov roj nplua nyeem uas tsis tau ntxuav, ncaj qha nkag mus rau hauv lub qhov cub rau kev kho cua sov, nws tseem yuav tsim kom muaj zog txo cov roj vim yog decomposition ntawm hydrocarbons, uas yuav corrode hluav taws xob cua sov qhov chaw.
