Kev siv cov hlau soldering

Ntxiv chromium rau hlau tuaj yeem txhim kho nws cov oxidation tsis kam thiab ua kom nws cov corrosion kuj. Chromium muaj nyob rau hauv ntau cov hlau nrog tshwj xeeb lub cev thiab tshuaj. Chromium hauv hlau yog ntxiv nrog ferrochrome. High carbon ferrochrome yog siv los ua tus neeg sawv cev alloying rau pob steel ({{0}}}.5 feem pua ​​- 1.45 feem pua ​​Cr), Tool steel, tuag steel (5 feem pua ​​- 12 feem pua Cr) thiab high-speed steel (3.8 feem pua ​​- 4.4 feem pua ​​Cr), uas tuaj yeem txhim kho lub hardenability ntawm steel thiab ua rau kom hnav tsis kam thiab hardness ntawm hlau. Ntxiv chromium rau cam khwb cia hlau tuaj yeem ua kom tawv tawv thiab txhim kho hnav tsis kam. Cov cuab yeej cuab tam ntawm cam khwb cia hlau tuaj yeem txhim kho los ntawm muaj 0.5 feem pua ​​​​rau 1.0 feem pua ​​​​chromium. High carbon ferrochromium thiab rauv qib ferrochromium yog dav siv los ua cov khoom siv hluav taws xob rau smelting stainless hlau (AOD lossis VOD txoj kev), txo cov nqi tsim khoom. Nruab nrab thiab qis carbon ferrochromium yog siv nyob rau hauv zus tau tej cov nruab nrab thiab tsawg carbon structural steel, carburized steel, zog, high-pressure blower hniav, valve daim hlau, thiab lwm yam. resistant steel, thiab hluav taws xob cua sov alloys.
