Tempering ntawm Steel yog dab tsi?

Cov hlau alloys yog tsim los ntawm kev sib xyaw ua ke ntawm cov ntsiab lus, xws li cov hauv cov zaub mov txawv. Txoj kev cov ntsiab lus sib xyaw ua ke hauv qab cua sov hloov cov khoom ntawm cov hlau. Tempering steel hloov cov khoom siv ntawm cov hlau, ua rau nws muaj zog thiab ruaj khov. Qhov no ua rau nws yog ib qho khoom siv zoo rau cov cuab yeej, springs, structural steel thiab txawm swords.

Vim li cas Temper Steel?

Hlau yog tempered los muab nws cov khoom siv haum rau nws daim ntawv thov. Nws yog txias hauv qab nws qhov melting point, txog 2,500 degrees Fahrenheit, thiab tom qab ntawd txias los txhim kho nws lub cev. Nws yog siv los ua kom lub zog, hardness thiab roughness ntawm steel. Thaum cov hlau yog cua sov thiab txias, nws lub cev hloov pauv. Tsis tas li ntawd, nws tuaj yeem yog:

Txo hardness thaum nce toughness (cov ntaub ntawv nyuaj tiv thaiv chipping ntawm kev cuam tshuam, qhov twg cov ntaub ntawv nyuaj tiv thaiv indentation thiab tawg ua ntej khoov)

Ua kom ductility (tso cai rau nws hloov pauv yam tsis muaj kev tawg)

Ua kom hnav tsis kam

Txhim kho machinability yog tias cov hlau xav tau kev ua haujlwm ntxiv

quenched thiab tempered steel txheej txheem

Koj feem ntau quench cov hlau kom tawv nws ua ntej tempering nws. Tom qab ntawd lub tempering kub txiav txim siab npaum li cas hardness koj tshem tawm ntawm cov hlau. Qhov kub siab dua, qhov hardness ntau dua raug tshem tawm. Piv txwv li, cov cuab yeej nyuaj yog tempered ntawm qhov kub thiab txias, thaum lub caij nplooj ntoos hlav hloov tau tempered ntawm qhov kub siab dua.

Hlau feem ntau yog cua sov hauv cov pa roj, tsis kam lossis induction furnaces nrog lub tshuab nqus tsev lossis cov roj inert los tiv thaiv oxidation. Tom qab cua sov cov hlau mus rau qhov ntsuas kub, qhov kub thiab txias yog khaws cia rau ib lub sij hawm nyob ntawm seb hom hlau thiab cov khoom siv tshuab ua kom tiav.

Tempered vs Annealed Steel: Qhov txawv yog dab tsi?

Ob qho tib si annealing thiab tempering koom nrog cua sov thiab txias steel los txhim kho nws lub cev. Txawm li cas los xij, tau hais tias, tempered steel tsis zoo ib yam li annealed steel. Annealing yog txheej txheem hlau ua haujlwm uas siv txoj kev ua kom txias qeeb dua thiab tswj tau ntau dua, thaum tempering yog txheej txheem hlau ua haujlwm uas siv txoj kev ua kom txias dua thiab tswj tau tsawg dua. Nrog annealing, steel yog rhuab mus rau ib tug tshwj xeeb kub thiab ces maj mam txias nyob rau lub sij hawm ntev. Annealed steel muaj hluav taws xob ntau dua li tempered steel, tab sis tempered steel muaj lub zog zoo thiab hardness.

Cov ntawv thov siv

Muaj ntau qhov kev lag luam uas vam khom rau cov hlau tsis zoo rau lawv cov khoom xav tau. Nov yog qee cov ntawv thov uas tuaj yeem siv rau koj qhov kev lag luam:

Kev tsim choj thiab kev tsim vaj tsev

Lub tank ruaj khov

Txiav ntug ntawm xyaum thiab saws

Liners rau trailer, pob tseg tsheb thauj khoom thiab chutes

iav

Deflector
