Cov pa roj ntws thiab nqus cov tubular hluav taws xob rauv tuaj yeem ua tiav ib txhij?

Hais lus nruj me ntsis, tubular hluav taws xob rauv tsis tuaj yeem ua pa lossis khiav tawm. Lub tubular hluav taws xob rauv yuav tsum tau nruab nrog lub kaw lus kaw ua ntej nws tuaj yeem tso cua lossis khiav tawm. Lub kaw lus kaw lus muab faib ua A configuration, B configuration thiab C configuration. Yuav tsum configure,

Cov txheej txheem kev teeb tsa tshwj xeeb: Ib qho kev teeb tsa: quartz raj, cov cuab yeej sib khi, peb txoj kev nkag yeeb nkab nrog valve, ib lub taub hau qhov hluav taws xob yeeb nkab nrog valve, ntsuas ntsuas ntsuas. B configuration: quartz raj, sealing ntaus ntawv, peb-txoj kev cua inlet yeeb nkab nrog valve, ib lub taub hau cua qhov hluav taws xob yeeb nkab nrog valve, lub ntsuas ntsuas ntsuas, roj ntws ntsuas ntaus ntawv. C: Quartz tube, sealing ntaus ntawv, peb-txoj kev cua inlet yeeb nkab nrog valve, ib lub taub hau cua qhov hluav taws xob yeeb nkab nrog valve, ntsuas ntsuas ntsuas, roj ntws ntsuas ntaus ntawv, dej txias ntaus ntawv.

Lub luag hauj lwm ntawm nitrogen gas nyob rau hauv lub tubular tsis kam rauv

Nws muaj ob yam teebmeem:

1. Kev tiv thaiv nitrogen. Nitrogen tuaj yeem tso pa tawm thiab tiv thaiv cov pa oxygen nkag mus, uas tuaj yeem tiv thaiv oxidation ntawm tubular hluav taws xob cua sov cov ntsiab lus thiab txhim kho lub neej ntawm tubular resistance furnace.

2. Nitrogen ua raws li lub tshav kub hloov nruab nrab.

Cov lus teb no raug pom zoo los ntawm tus neeg nug

Puas muaj peev xwm ua kom npau taws los txo cov tawv nqaij tom qab muag nitriding?

Tempering tuaj yeem txo qhov hardness ntawm mos nitriding. Nws tsis tau qhuav heev, thiab mos nitrogen feem ntau tsis tas yuav tsum muaj qhov txwv ntawm hardness. Koj cov neeg siv khoom puas xav txog qhov teeb meem ntawm brittleness? Qhov no tuaj yeem qhia nws tias nws tsis tsim nyog, vim tias qhov sib txawv ntawm hardness tsis cuam tshuam nrog brittleness.

Puas muaj tus qauv rau kev ntsuas qhov tawv tawv ntawm nitrocarburized workpieces?

Feem ntau hais lus, qhov nyuaj ntawm qhov nruab nrab-carbon alloy steel tom qab kev kho nitriding yuav tsum tshaj 500, tab sis nws qhov tseeb tus nqi yog qhov nyuaj los txiav txim siab. Nyob rau hauv lub sij hawm, tus neeg sab nrauv yuav tsis muab ib qho kev piav qhia los ua pov thawj tias nws cov hardness saum npoo yog qhov tseeb tus nqi. Kev hais lus theoretical, lub npe hu ua hardness yuav tsum ntsuas los ntawm qhov chaw. Qhov tseem ceeb yog qhov zoo ntawm qhov chaw yuav tsum zoo, xws li roughness thiab indentation zoo (yuav tsum tau meej, thiab qhov sib piv yuav tsum tsis txhob tshaj tus qauv), yog li polishing tseem tsim nyog.

Lwm lub tuam txhab ntsuas qhov nyuaj ntawm qhov chaw los ntawm qhov hla ntu. Qhov tseeb, qhov nyuaj ntawm qhov nitriding yog hais txog qhov nyuaj ntawm cov txheej txheej, yog li nws tseem tuaj yeem txheeb xyuas qhov sib txawv ntawm cov txheej txheem sib xyaw, tab sis muaj ob qhov yuav tsum tau ua ua ntej: 1. Txhua tus neeg muag khoom hauv cov khoom siv thiab tus neeg tau txais kev pom zoo; 2. Lub load yuav tsum me me, xws li 0.1 los yog 0.05 kg, kom paub meej tias yuav tau txais ib tug ntshiab indentation.
