Kev faib tawm thiab tsim txheej txheem ntawm Medium-Frequency Bent Pipes:
Nrog rau kev siv dav hauv kev lag luam ntawm cov kav dej nruab nrab zaus, cov kav dej no paub txog lawv cov kev ua haujlwm tsis zoo, uas tuaj yeem ua rau muaj teeb meem xws li chip txiav, xov xov puas, thiab coj mus siv thaum threading stainless hlau nruab nrab zaus bent kav. . Qhov no, nyob rau hauv lem, cuam tshuam kev ua hauj lwm efficiency thiab zoo. Cia peb delve rau hauv kev faib tawm thiab tsim cov txheej txheem ntawm cov kav dej nruab nrab zaus.
I. Kev faib tawm ntawm Medium-Frequency Bent Pipes:
Medium-frequency bent kav tuaj yeem raug cais raws li cov qauv thiab cov khoom siv:
- Raws li cov qauv: Qhov no suav nrog cov kav dej nruab nrab zaus khoov (xws li cov qauv hauv teb chaws), cov kav dej tsis muaj qhov nruab nrab zaus, thiab cov qauv thoob ntiaj teb xws li German, Japanese, American, thiab British qauv.
- Raws li cov ntaub ntawv: Cov kav dej nruab nrab zaus tuaj yeem ua los ntawm cov pa roj carbon steel, stainless hlau, lossis hlau alloy.
Cov pa roj carbon steel nruab nrab zaus khoov cov kav dej feem ntau muaj me me ntawm silicon, manganese, sulfur, thiab phosphorus. Cov pa roj carbon steel tuaj yeem muab faib ua peb hom raws li nws lub hom phiaj: cov qauv carbon steel, carbon tool steel, thiab dawb-txiav cov qauv hlau. Cov qauv carbon steel tau muab faib ntxiv rau hauv kev tsim kho cov qauv hlau thiab tshuab tsim cov qauv hlau.
Tsis tas li ntawd, cov pa roj carbon steel tuaj yeem raug cais raws li cov txheej txheem deoxidation (steel boiling, tua steel, semi-tua steel, thiab tshwj xeeb tua steel), cov ntsiab lus carbon (tsawg-carbon steel, nruab nrab-carbon steel, thiab high-carbon steel), smelting. Cov txheej txheem (qhib-hearth steel, converter steel, thiab hluav taws xob rauv hlau), thiab cov ntsiab lus phosphorus thiab sulfur (cov pa roj carbon zoo ib yam thiab cov pa roj carbon zoo).
II. Kev tsim cov txheej txheem ntawm Medium-Frequency Bent Pipes:
Cov txheej txheem tsim khoom rau cov kav dej nruab nrab zaus khoov muaj cov kauj ruam hauv qab no:
1. Lub induction kauj yog muab tso rau ib ncig ntawm cov yeeb nkab steel yuav tsum tau khoov, thiab txoj kev khoov yog pib.
2. Qhov khoov ntawm cov yeeb nkab steel yog ceev ceev siv lub coolant. Qhov no suav nrog cua sov cov yeeb nkab thaum tib lub sijhawm thawb thiab khoov nws, tom qab ntawd txias tam sim ntawd.
3. Mechanical propulsion yog siv nyob rau tom qab kawg ntawm cov yeeb nkab steel, thiab ib tug neeg kho tshuab viav caj npab tuav cov yeeb nkab taub hau nyob rau hauv qhov chaw. Cov yeeb nkab steel yog rhuab los ntawm kev siv hluav taws xob nruab nrab zaus hauv qhov induction kauj. Thaum qhov kub ntawm cov yeeb nkab steel mus txog lub xeev yas, qhov corrosion kuj ntawm nruab nrab-zaus bent yeeb nkab nyob ntawm cov ntsiab lus alloying hauv cov hlau. Chromium yog lub hauv paus tseem ceeb rau kev ua tiav kev tiv thaiv corrosion hauv stainless hlau khoov. Thaum cov ntsiab lus chromium nyob rau hauv cov hlau nce mus txog kwv yees li 1.2%, nws reacts nrog oxygen nyob rau hauv nruab nrab corrosive, tsim ib tug nyias oxide zaj duab xis nyob rau hauv steel nto, zoo tiv thaiv corrosion ntxiv ntawm cov hlau.
Txoj kev tsim cov kav dej nruab nrab zaus yuav tsum tau ua raws li cov txheej txheem tshwj xeeb thiab cov qauv zoo kom tsis txhob muaj teeb meem ntau lawm. Cov txheej txheem yog complex thiab koom nrog vuam raws li cov ntaub ntawv sib txawv thiab kev siv, maj mam tsim cov yeeb nkab nyob rau hauv kev tswj lub siab.
Cov ntaub ntawv qhia saum toj no yog npaj los muab kev nkag siab zoo ntawm kev faib tawm thiab tsim cov txheej txheem ntawm cov kav dej nruab nrab zaus.
