Heating wire is a common heating element and plays an important role in people's lives. Iron-chromium-aluminum alloy heating wire and nickel-chromium alloy heating wire are the two most commonly used heating wires. They each have their own advantages and disadvantages. The following is a detailed summary for you:
1. Hlau-chromium- aluminium alloy cua sov hlau
Qhov zoo ntawm hlau-chromium- aluminium alloy cua sov hlau: siab ua haujlwm kub, qhov kev sim qhia tau hais tias qhov siab tshaj plaws ua haujlwm kub ntawm hlau-chromium- aluminium alloy cua sov hlau tuaj yeem ncav cuag 1400 degree. Cov hlau -chromium- aluminium alloy cua sov hlau muaj lub neej ntev kev pab cuam, siab resistivity, siab nto composite, thiab zoo oxidation kuj.
Qhov tsis zoo ntawm cov hlau -chromium- aluminium alloy cua sov hlau: Lub zog ntawm hlau -chromium- aluminium alloy cua sov hlau yog qhov kub thiab txias ib puag ncig, thiab plasticity ntawm hlau -chromium- aluminium alloy cua sov hlau yuav nce nrog qhov nce ntawm qhov kub thiab txias, uas yog hais tias, hlau -chromium- aluminium alloy cua sov hlau yog feem ntau deformation ntawm siab. kub. Thiab nws tsis yog yooj yim los kho tom qab deformation.
2. Nickel-chromium alloy cua sov hlau
Qhov zoo ntawm npib tsib xee-chromium alloy cua sov hlau: siab zog nyob rau hauv qhov kub thiab txias ib puag ncig, ntev -lub sij hawm kub kub ua hauj lwm tsis yooj yim rau deform, nyuaj rau hloov cov qauv, thiab cov kub plasticity ntawm npib tsib xee. -chromium alloy cua sov hlau yog qhov zoo, thiab kev kho tom qab deformation yog qhov yooj yim. Tsis tas li ntawd, cov nickel-chromium alloy cua sov hlau muaj siab emissivity, tsis yog-magnetic, zoo corrosion kuj thiab lub neej ntev kev pab cuam.
Qhov tsis zoo ntawm nickel-chromium alloy cua sov hlau:
Kev khiav hauj lwm kub tsis tuaj yeem ncav cuag qib ntawm cov cua sov yav dhau los. Nickel-chromium alloy cua sov hlau yuav tsum tau siv cov nickel. Tus nqi ntawm cov hlau no siab dua cov hlau, chromium, thiab txhuas. Yog li ntawd, cov nqi tsim khoom ntawm nickel-chromium alloy cua sov hlau yog qhov siab, uas tsis tsim nyog rau kev tswj tus nqi.
