Txhua qib steel muaj nws tus kheej cov yam ntxwv thiab cov khoom. Hauv kev tsim cov khoom lag luam, metallurgists sim ua kom paub tseeb tias tag nrho cov yam ntxwv xav tau yog nyob rau theem siab tshaj plaws. Txawm li cas los xij, nws tsis tuaj yeem tsim cov alloy uas yuav haum rau txhua lub hom phiaj. Vim li no, koj yuav tsum xaiv cov kev ntsuas uas koj yuav tsum tau txhim kho txhawm rau txhawm rau ua tiav cov hlau alloy hauv ib qho kev taw qhia.

Kev piav qhia ntawm steels

Steel 40 x 13 yog qhov xav tau tshaj plaws hauv kev tsim cov riam. Cov yam ntxwv ntawm cov khoom no yog qhov zoo tshaj plaws los tsim cov khoom zoo li no. Ntawm no nws tsim nyog nkag siab tias qhov nyuaj ntawm cov tshuaj muaj pes tsawg leeg, qhov nyuaj thiab ntev ntawm kev ua haujlwm yuav yog. Tsis tas li ntawd, tus nqi ntawm cov khoom tiav kuj tseem yuav nce ntxiv. Nws tseem ceeb heev kom paub tias cov hlau zoo tshaj plaws rau kev ua riam, piv txwv li, tsuas yog tau txais tom qab kev kho cua sov xwb.

Basic qualities of the alloy

Cov yam ntxwv tseem ceeb ntawm steel 40 x 13:

• Ib qho ntawm thawj thiab tseem ceeb tsis tau yog qhov kub siab ua haujlwm ntawm cov khoom.
• Qhov thib ob parameter, uas kuj yogplays lub luag haujlwm tseem ceeb heev - nws tiv taus ntau hom kev xeb. Qhov no ua rau kom lub neej kev pab cuam ntawm tag nrho cov khoom uas yog tsim los ntawm cov hom no.
• Steel 40 x 13 yog hais txog cov khoom sib xyaw uas yuav luag tsis muaj xeb.

Cov khoom lag luam no feem ntau tshuav nws cov khoom tiv thaiv corrosion siab rau txoj kev tsim khoom siv thiab ntev, uas yuav tsum muaj xws li theem xws li hardening ntawm cov khoom. Qhov tshwm sim ntawm cov txheej txheem zoo li no yog kev ua tiav ntawm cov khoom siv xws li carbide. Qhov no yog qhov muab kev tiv thaiv siab tiv thaiv corrosion.

Nws yuav tshwm sim tias qhov kev tiv thaiv rau qhov tsis xws luag tuaj yeem txo qis. Feem ntau qhov no tshwm sim yog hais tias tus nqi ntawm carbide nyob rau hauv chromium tsawg heev los yog melting kub ntawm cov hlau poob mus rau 600 degrees. Txawm li cas los xij, nrog kev ua haujlwm zoo, qhov no feem ntau tsis tshwm sim.

Steel 40 x 13 yog melted nyob rau hauv tshwj xeeb qhib rauv. Txhawm rau ua qhov txheej txheem no, koj tuaj yeem siv induction hom furnaces. Cov txheej txheem ntawm melting cov hlau nws tus kheej yuav siv qhov chaw ntawm qhov kub ntawm 850 mus rau 1100 degrees Celsius. Txhawm rau kom tsis txhob tawg thaum lub sijhawm cua sov muaj zog, kev ua haujlwm thev naus laus zis yuav tshwm sim nyob rau theem, qhov chaw cua sov thiab txias ntawm cov khoom sib hloov.

Khoom Siv Khoom

Kev kho cua sov ntawm cov hlau 40 x 13 yog txheej txheem uas feem ntau txiav txim siab cov yam ntxwv zoo ntawm cov hlau. Tom qab dhau los ntawm theem no, cov khoom muaj cov khoom xws li carbides, martensites, residual austenites. Yog ibThaum lub sij hawm kho cua sov ntawm cov hlau, qhov kub yuav siab tshaj 1050 degrees Celsius, ces ntau austenite hais yuav raug tsim. Qhov no yuav ua rau lub fact tias hardness ntawm steel 40x13 yuav txo. Yog tias koj txo qis qhov kub ntawm cov hlau mus rau 450-550 degrees Celsius, koj tuaj yeem tau txais cov nyhuv xws li cov tawv tawv thib ob. Qhov no yog vim qhov tseeb hais tias nyob rau ntawm qhov kub ntawm no cov khoom hu ua nplua carbide pib los nag.

Daim ntawv thov ntawm alloy

Lub hom phiaj tseem ceeb ntawm kev siv hlau 40 x 13 yog kev tsim cov khoom pheej yig, tab sis muaj zog txaus riam chav ua noj. Tag nrho cov khoom tsim los ntawm cov hlau no zoo heev rau kev siv hauv tsev, vim nws yuav luag tsis muaj xeb. Tsis tas li ntawd, nws tsuas yog txaus kom ntse riam uas ua los ntawm qib steel no. Lawv siv tau yooj yim heev thiab saib xyuas lawv.

Qhov zoo ntawm cov hlau yog tias nws tsis yog tsuas yog ntse txaus kom ua tiav cov khoom noj, tab sis nws kuj yog ib puag ncig zoo, uas ua rau nws tsim nyog siv hauv chav ua noj.

Lwm cov kev taw qhia ntawm kev siv cov hlau no yog kev tsim cov scalpels kho mob. Nws tseem muaj peev xwm tsim tau lwm qhov chaw xws li springs, bearings thiab lwm yam. Qhov tsuas yog qhov tsis zoo ntawm cov khoom siv no yog nws qhov tsis tshua muaj kev tiv thaiv ib puag ncig hnyav, nrog rau qhov kub thiab txias. Vim li no, cov hlau no tsis haum rau kev siv vuam, piv txwv li.

tshuaj xyuas khoom

Steel 40 x 13 yog nyob rau hauv qhov kev thov siab, uas tau pom zoo hauv cov kev tshuaj xyuas zoo. Lub ntsiab zoo ntawm hom no yog lub neej kev pab cuam. Txawm tias tom qab sharpening, cov riam yuav nyob twj ywm ntse mus ntev. Cov khoom tsis raug cuam tshuam rau corrosion, uas kuj tau txais txiaj ntsig zoo los ntawm cov neeg siv khoom. Nrog rau tag nrho cov no, tus nqi ntawm cov khoom tsim los ntawm cov khoom siv no tau txais tag nrho, uas ua rau qhov kev xav tau ntawm cov neeg siv khoom zoo tshaj plaws.

Nws tsuas yog sau tseg tias koj yuav tsum ceev faj nrog cov khoom tsim los ntawm cov hlau no, vim nws hloov tau yooj yim hauv nws tus kheej. Vim li no, nws yog tsis yooj yim sua kom siv ib tug riam rau ua ib tug nyuaj nto. Nws tseem tsim nyog sau cia tias khaws riam thiab lwm yam cuab yeej txiav hauv qhov chaw ntub dej thiab ntub dej tsis tsim nyog - qhov no yuav ua rau lawv tsis ua haujlwm sai.
