High-frequency Quenching yog dab tsi?

High-frequency quenchingfeem ntau yog siv rau saum npoo quenching ntawm industrial hlau qhov chaw.Nws yog ib hom kev kho cua sov hlau uas ua rau qhov chaw ua hauj lwm nto tsim ib qho kev cuam tshuam tam sim no, sai sai cua sov ntawm qhov chaw, thiab tom qab ntawd sai sai quenching.Induction cua sov khoom, uas yog, lub workpiece induction cua sov, thiaj li yuav nto quenching. khoom siv.

Lub hauv paus ntsiab lus ntawm induction cua sov: Lub workpiece yog muab tso rau hauv cov cua nrog lub hollow tooj liab yeeb nkab nyob rau hauv sensor, tom qab nkag mus rau intermediate zaus los yog high zaus alternating tam sim no (ac), tsim nyob rau hauv lub nto nrog lub zaus ntawm induced tam sim no, lub workpiece nto. los yog cov cua kub ceev hauv zos (ob peb vib nas this rau qhov kub thiab txias ntawm 800 ~ 1000 ℃, cov tub ntxhais tseem nyob ze rau hauv chav tsev kub) tam sim ntawd tom qab ob peb feeb sai sai txau (dip) dej txias (los yog tshuaj tsuag roj immersion txias) ua kom tiav qhov hluav taws kub ua haujlwm, Ua kom cov workpiece nto los yog hauv zos kom ua tau raws li qhov yuav tsum tau muaj hardness.

Piv nrog rau cov cua sov zoo tib yam quenching, nws muaj:

1. Cov cua kub ceev ceev ceev heev, uas tuaj yeem nthuav dav ntawm A lub cev hloov pauv kub thiab txo lub sijhawm hloov pauv.

2. Zoo heev cryptocrystalline martensite tuaj yeem tau txais ntawm qhov chaw ntawm lub workpiece tom qab quenching, thiab hardness yog me ntsis siab dua (2 ~ 3HRC).Low brittleness thiab siab qaug zog.

3. Lub workpiece kho los ntawm cov txheej txheem tsis yooj yim rau oxidize thiab decarbonize, thiab txawm tias qee qhov workpiece tuaj yeem ncaj qha sib dhos thiab siv tom qab ua tiav.

4, lub hardening txheej yog sib sib zog nqus, yooj yim los tswj cov kev khiav hauj lwm, yooj yim kom paub mechanization, automation.

5, nplaim taws kub quenching

High zaus quenching yog siv rau lub workpiece uas yuav tsum tau dais qhov kev txiav txim ntawm alternating load xws li torsion thiab dabtsi yog khoov.Nws yuav tsum tau cov txheej txheej saum npoo kom muaj kev ntxhov siab ntau dua los yog hnav tsis kam tshaj qhov tseem ceeb, thiab qhov chaw ntawm lub workpiece yuav tsum muaj zog.Nws yog tsim rau steel nrog cov ntsiab lus carbon Peb = 0.40 ~ 0.50%.
