Carbide vs high-ceev steel

Carbide thiab High-ceev steel (hss) yog ob qho ntaub ntawv tseem ceeb siv hauv kev tsim cov cuab yeej, txhua tus nrog nws cov khoom ntiag tug thiab cov ntawv thov. Carbide, feem ntau muaj ntawm tungsten carbide, yog kev ua kev zoo siab rau nws qhov kev ua kom nruj thiab hnav tsis kam, ua rau nws zoo rau kev ua tau zoo machining. Ntawm qhov tod tes, qib ceev-ceev steel yog nyiam rau nws cov tawv thiab muaj peev xwm tiv thaiv kom kub siab, uas tso cai rau nws kom tswj tau txiav cov ntawv thov ntev dua nyob rau hauv ntau yam kev siv. Thaum ob cov ntaub ntawv zoo li cov ntsiab lus, nkag siab txog lawv qhov sib txawv yog qhov tseem ceeb rau xaiv cov cuab yeej zoo rau ib txoj haujlwm tshwj xeeb, ua kom muaj kev ua haujlwm thiab precision hauv kev ua haujlwm.

Puas yog nws ua tau rau weld carbide thiab qib ceev?

Cov tswv yim vuam sib txawv txawv ntawm carbide thiab qib ceev ceev steel, txhua qhov kev sib tw tshwj xeeb:

1. Carbide Vuam:

Carbide cov cuab yeej, tshwj xeeb yog tungsten carbide, feem ntau tsis welded nyob rau hauv kev nkag siab ib txwm vim lawv hardness thiab britleness. Hloov chaw, carbide yog feem ntau brazed, tus txheej txheem uas koom nrog carbide rau ib tug hlau substrate siv cov tub lim cov khoom siv thaum kub. Cov kev txiav txim siab tseem ceeb suav nrog:

Cov tswv yim Brazing: Cov tswv yim Brazing tshwj xeeb yuav tsum ua haujlwm kom ntseeg tau tias qhov sib txuas lus muaj zog yam tsis muaj kev sib luag ntawm carbide.

Kev tswj qhov kub thiab txias: Kev tswj qhov ntsuas kub thiab txias yog qhov tseem ceeb, raws li cov cua sov ntau dhau tuaj yeem ua rau tawg lossis txo qis carbide.

Kev npaj saum npoo: kev npaj zoo yog qhov tseem ceeb rau kev ua tiav cov khoom nplaum zoo thaum lub sijhawm ua haujlwm.

2. Kev kub ceev-ceev steel vuam:

High-ceev steel yog kev hloov kho ntau ntxiv rau cov kev siv vuam siv. Nws tuaj yeem welded siv cov hau kev xws li roj tungsten arc vuam (gtaw) lossis thaiv cov hlau vuam (smaw). Kev txiav txim siab rau vuam HSS suav nrog:

Preheating: preheating cov hlau ua ntej vuam yuav pab txo cov kev pheej hmoo ntawm kev tawg.

Cov Khoom Siv Khoom Siv Ua Si: Xaiv cov tub muab cov khoom siv yog qhov tseem ceeb kom paub meej tias kev sib raug zoo thiab muaj zog.

Kev Kho Mob Tom Qab Weld: Tom qab Weld Kho Kom Sov tuaj yeem txhim kho cov khoom siv hluav taws xob ntawm kev welded sib koom tes.

Hauv cov ntsiab lus, thaum carbide yog feem ntau brazed tsis muaj welded, cov kev xav tau high-high-ceev siv tau siv cov txheej txheem tshwj xeeb, kom ntseeg tau tias muaj zog, txhim khu kev qha pob qij txha.

Khawb tsis kam tiv: carbide vs. high-ceev steel

Ob leeg carbide thiab high-ceev steel tau naag ntawv xaim, tab sis lawv cov kev ua tau zoo sib txawv raws cov khoom siv:

1. Carbide:

Carbide yog muaj npe rau nws tshwj xeeb hardness, qeb duas ib ncig ntawm 9 ntawm Mohs nplai. Qhov no ua rau nws tau kos heev-resistant, zoo tagnrho rau cov ntawv thov uas muaj cov ntaub ntawv phem. Txawm li cas los xij, thaum carbide tuaj yeem tiv thaiv cov khawb ntsuab, nws tseem muaj ntau nkev, uas yuav ua rau chipping hauv qab kev ntxhov siab ntau dhau.

2. Cov Hlau Ceev-Ceev:

High-ceev steel muaj qib nyuaj ntawm kwv yees li 6 txog 7.5 ntawm Mohs nplai, ua rau nws tsis tshua muaj dua carbide. Txawm li cas los xij, cov cuab yeej siv hss tau paub txog lawv cov kev nruj thiab ductility, uas tso cai rau lawv kom cov xwm txheej zoo, txo qis kev puas tsuaj tas mus li.

Feem ntau, carbide muaj cov ntawv nthuav dav zoo dua, thaum cov hlau ceev ceev muab cov kev sib raug zoo dua nyob hauv kev cuam tshuam.

Nrib pleb tsis kam: 

1. Carbide:

Carbide lub hardness, thaum ua kom tau zoo rau kev txiav, ua rau nws raug kev cuam tshuam ntau dua kom tawg nyob rau hauv kev cuam tshuam los yog kev ntxhov siab. Nws brittleness tuaj yeem ua rau kev puas tsuaj rau kev ua tsis tiav yog tias tsis daws tau zoo. Yog li, carbide cov cuab yeej yog qhov zoo tshaj plaws rau kev sib xws, khov kho tej yam kev mob.

2. Cov Hlau Ceev-Ceev:

High-ceev steel, nrog nws cov ductile xwm, cov khoom pov thawj zoo tsis kam mus nraus kom pom kev carbide. Nws tuaj yeem ua kom ncua kev ntxhov siab thiab chaw thau khoom ncig mus tsis muaj fracturing, ua rau nws xaiv tau txoj kev cuam tshuam uas cuam tshuam ntau yam.

Hauv cov ntsiab lus, cov tshuab ceev ceev feem ntau yog feem ntau tiv taus tawg dua carbide vim nws txoj kev nruj thiab yooj.

Yuav ua li cas sib txawv carbide thiab qib ceev ceev?

1. Pom:

Carbide: Feem ntau muaj kev tsaus ntuj, ntau dua li nws yog xim hlau thiab feem ntau siv hauv cov ntsiab lus lossis cov lus qhia.

High-ceev steel: feem ntau pom lub zog dua thiab muaj ntau zaus pom hauv cov cuab yeej lub cev.

2. Qhov hnyav:

Carbide: Denser thiab hnyav dua piv rau cov hlau ceev.

High-ceev steel: sib dua, ua kom nws yooj yim dua los lis hauv cov cuab yeej sib dhos.

3. Hardness:

Carbide: nyuaj siab, ua nws haum rau kev ua haujlwm hnyav.

High-ceev steel: nyuaj, tab sis tsis nyuaj li carbide, cia rau qee qhov hloov qee yam.

4. Cov Khoom Sib Nqus:

Carbide: feem ntau tsis muaj hlau nplaum.

High-ceev steel: sib nqus, uas tuaj yeem pab hauv kev paub qhov sib txawv ntawm ob cov ntaub ntawv.

5. Kev sim ntsuas:

Carbide: tsim lub ntsej muag kaj, luv luv thaum ntaus.

High-ceev steel: tsim ntev-ntev, ntau lub txim taws.

Hauv kev xaus, thaum ob tus neeg ua haujlwm carbide thiab qib ceev yog cov ntaub ntawv tseem ceeb hauv kev lag luam txiav, lawv pab cov laj thawj sib txawv raws li lawv cov peev txheej. Carbide exhels nyob rau hauv hardness thiab kos tsis kam, ua rau nws zoo tagnrho rau kev txiav abrasive, tab sis ntau nkig. High-ceev steel muaj cov kev nruj dua thiab tiv thaiv kom tawg, ua rau nws haum rau kev siv machinamic kev ua haujlwm.

Nkag siab cov kev sib txawv no yog qhov tseem ceeb rau kev xaiv cov cuab yeej zoo rau cov ntawv thov, kom ua tiav cov kev ua tau zoo thiab ua kom ntev hauv kev ua haujlwm machining. Thaum kawg, qhov kev xaiv ntawm carbide thiab high-ceev steel yuav tsum xav txog yam uas muaj ntau yam xws li qhov kev txiav txim siab, thiab kev saib xyuas kev lag luam kom ua tiav cov txiaj ntsig zoo hauv kev tsim cov txheej txheem.
