Lub hom phiaj ntawm steel pob nyuaj sib tsoo yog kom tshem tawm qhov tsis xws luag hauv cov txheej txheem yav dhau los thiab decarburization, oxide txheej thiab txheej txheej troostite tsim thaum kho cua sov, ntxiv txhim kho qhov raug qhov tseeb, kheej kheej qhov tseeb thiab qhov chaw zoo, thiab npaj rau cov txheej txheem sib tsoo tom ntej. . Kev sib tsoo nyuaj yog ib txoj kev sib tsoo uas siv cov cam khwb cia hlau ua ib qho kev sib tsoo thiab lub log sib tsoo ua cov cuab yeej abrasive los ua cov txheej txheem ntawm lub pob steel, raws li pom hauv daim duab 1.
Thaum lub sij hawm sib tsoo nyuaj, lub pob steel yog coj los ntawm lub voj voog ntawm qhov chaw ua haujlwm ntawm lub phaj ruaj khov, thiab lub pob steel yog nias rau ntawm qhov chaw ua haujlwm ntawm lub log sib tsoo, thiab lub pob steel yog hauv av hauv qhov kev txiav txim siab. . Tom qab lub pob steel txuas ntxiv dov qhov chaw ua haujlwm ntawm lub log sib tsoo, grooves yuav maj mam tsim ntawm qhov chaw ua haujlwm. Thaum lub sij hawm sib tsoo txheej txheem ntawm lub pob steel, vim hais tias lub linear tshaj tawm nyob rau sab nraud ntawm lub sib tsoo log zawj yog ntau dua li linear tshaj tawm ntawm lub puab ntug ntawm lub sib tsoo log zawj, thaum lub sij hawm ua hauj lwm ntawm lub sib tsoo log, zawv zawg kev sib txhuam yuav inevitably. tshwm sim ntawm qhov chaw sib cuag ntawm lub log sib tsoo thiab lub pob steel; raws li qhov zawj qhov tob zuj zus raws li kev sib txhuam nce, cov zawv zawg kev sib txhuam kuj nce; zawv zawg kev sib txhuam ntawm ntug hauv qab ntawm qhov sib tsoo log zawj yog me me, tab sis cov nyhuv dov yog qhov loj tshaj plaws; Nyob rau hauv no txoj kev sib txhuam, cov nplej abrasive nyob rau saum npoo ntawm kev sib tsoo log zawj cuam tshuam rau cov hlau Lub pob ua raws li kev sib tsoo. Lub zog ntawm lub pob steel thaum lub sij hawm sib tsoo cov txheej txheem kuj yog complex, nrog rau lub kiv puag ncig ntawm lub steel pob nyob ib ncig ntawm lub axis ntawm lub sib tsoo log thiab kev sib hloov ntawm lub pob steel nyob ib ncig ntawm nws lub hauv paus. Kev sib hloov tuaj yeem hloov pauv kev coj ua tsis tu ncua, yog li txhua qhov taw tes ntawm lub pob steel muaj lub sijhawm rau kev sib tsoo; lub kiv puag ncig koom tes nrog kev sib tsoo cyclic ntawm lub tshuab cuab yeej kom thaum kawg paub txog cov txheej txheem sib tsoo nyuaj ntawm lub pob steel.
Kev sib tsoo lub log yog ib qho tseem ceeb hauv cov txheej txheem steel pob nyuaj sib tsoo. Ua ke nrog cov yam ntxwv ntawm kev sib tsoo nyuaj, txhawm rau ua kom zoo dua qhov tseeb thiab qhov zoo ntawm lub pob steel, cov qauv hauv qab no yuav tsum tau ua raws li kev sib tsoo vitrified rau steel pob nyuaj sib tsoo:
1. Sib tsoo log specifications thiab qhov ntev
Lub ntsiab specifications thiab qhov ntev ntawm lub sib tsoo log muaj xws li: sab nraud txoj kab uas hla, lub qhov taub thiab thickness, uas yog tsim nyog xaiv raws li cov kev ua tau zoo ntawm lub tshuab cuab yeej. Qhov ntau thiab tsawg thiab specifications ntawm ceramic sib tsoo log rau steel pob nyuaj sib tsoo yog qhia nyob rau hauv Table 1.

2. Hom abrasives
Abrasives yog ib feem tseem ceeb ntawm cov cuab yeej abrasive thiab feem ntau ua lub luag haujlwm sib tsoo. Kev xaiv ntawm hom abrasive thaum tsim cov cuab yeej abrasive feem ntau yog nyob ntawm cov khoom ntawm cov khoom sib tsoo. Cov kabmob steel pob feem ntau yog ua los ntawm cov kabmob steel, thiab corundum-based abrasives tuaj yeem nyiam. Brown corundum muaj zog tsis kam rau crushing thiab siab toughness, thiab feem ntau yog siv nyob rau hauv zus tau tej cov steel pob nyuaj sib tsoo ceramic sib tsoo log. Thaum lub sij hawm sib tsoo cov txheej txheem, thaum cov nplej abrasive passivated, vim lub siab toughness ntawm corundum abrasives, cov nplej abrasive tsis tuaj yeem tawg los ntawm lawv tus kheej hauv kev sib tsoo kom nthuav tawm cov npoo tshiab, uas cuam tshuam rau kev sib tsoo. Yog li ntawd, cov txheej txheem steel pob kub kho thiab cov txheej txheem sib tsoo ua ke. Txhawm rau txhim kho cov yam ntxwv ntawm kev txiav, koj tuaj yeem xaiv los qhia txog silicon carbide abrasives kom tsim nyog, uas yog, vitrified sib tsoo log rau steel pob nyuaj sib tsoo siv cov sib xyaw ntawm corundum thiab silicon carbide.
3. Abrasive particle loj
Thaum xaiv abrasive particle loj, nws yog tsuas yog raws li kev sib tsoo nto roughness thiab kev sib tsoo efficiency. Ua ntej tshaj plaws, nws yog ib qho tsim nyog los xyuas kom meej tias qhov roughness ntawm lub workpiece tom qab sib tsoo ua tau raws li qhov yuav tsum tau ua. Yog hais tias qhov luaj li cas yog ntxhib heev, lub coarse-grained abrasive yuav txiav ib tug loj npaum li cas thaum lub sij hawm sib tsoo thiab ua kom muaj cua sov ntau dua, tab sis qhov chaw sov yuav me me, thiab me me me me yuav yooj yim tshwm sim ntawm lub pob steel. Yog hais tias qhov loj me me dhau lawm, nws yuav cuam tshuam rau kev sib tsoo ntawm ib sab, thiab ntawm qhov tod tes, vim qhov me me txiav quab yuam ntawm qhov loj me me, steel pob thiab zawj arc nto feem ntau muaj nyob hauv daim ntawv. ntawm kev sib txhuam, uas generates ib tug loj npaum li cas ntawm kev sib txhuam thaum tshav kub kub, thiab nto ntawm steel pob Burns yuav tshwm sim yooj yim. Raws li qhov ua tau raws li qhov yuav tsum tau ua ntawm machining nto roughness, sim siv coarse-grained abrasives los txhim kho kev sib tsoo efficiency ntawm cov cuab yeej sib tsoo. Rau qhov loj me me ntawm ceramic sib tsoo log rau steel pob nyuaj sib tsoo, thov xa mus rau Table 2.

4. Sib tsoo log hardness
Hardness yog ib qho tseem ceeb ntsuas ntsuas qhov zoo ntawm kev sib tsoo log. Rau cov pob zeb sib tsoo siv rau steel pob nyuaj sib tsoo, yog tias lub hardness yog mos heev, cov abrasives yuav poob ntxov thaum lub sij hawm sib tsoo, nthuav tawm cov nplej tshiab. Cov nplej abrasive tshiab no muaj ntau dua Sharp sib tsoo hniav muaj zog sib tsoo muaj peev xwm thiab ua kom muaj cua sov ntau. Yog tias qhov txias txias tsis tau raws sijhawm, nws yuav ua rau qhov chaw kub hnyiab ntawm lub pob steel. Nyob rau tib lub sij hawm, vim hais tias lub hardness ntawm lub sib tsoo log yog mos heev, qhov zawj yuav raug txo thaum lub sij hawm sib tsoo txheej txheem. Kev txwv ntawm lub pob steel ntawm qhov zawj tuaj yeem yooj yim ua rau muaj kev hloov pauv ntau dhau ntawm txoj kab uas hla ntawm lub pob steel. Yog hais tias lub hardness siab dhau lawm thiab tus kheej-sharpening cov cuab yeej tsis zoo, raws li qhov zawj arc nto txuas ntxiv mus zom cov pob steel, txoj kab uas hla ntawm lub pob steel yuav me dua thiab qhov zawj arc nto thiab steel pob nto tsis zoo, txo qhov zawj qhov cuam tshuam rau lub pob steel. Lub zog khi tau yooj yim ua rau cov pob hlau yob ua ke, thiab nyob rau hauv cov xwm txheej hnyav, cov kab hluav taws xob yuav tshwm sim rau saum npoo ntawm cov pob hlau.
Qib hardness ntawm vitrified sib tsoo log siv rau kev sib tsoo steel pob yog qib Y. Qhov tob ntawm cov xuab zeb blasting hardness qhov tob hauv 28cm3 xuab zeb chamber ntawm ceramic sib tsoo log rau sib tsoo steel pob tsis ntau dua 0 .6 hli. Lub hardness ntawm kev sib tsoo log yog ua raws li cov kev cai. Peb qhov kev ntsuam xyuas sandblasting hardness tau ua nyob rau txhua qhov chaw, thiab qhov ntsuas thib peb yog tus nqi hardness kawg. Rau kev xaiv hardness ntawm ceramic sib tsoo lub log rau steel pob nyuaj sib tsoo, thov mus rau Table 3.
