Unyango lobushushu olungaphezulu luhlulwe lwahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlula-hlula kabini: inye inyathelo lokucingela kunye nokunyangwa kobushushu, kwaye enye inyanga inyanga. Indlela yovavanyo lobunzima ngolu hlobo lulandelayo:
1. Ukucima umphezulu kunye nonyango lobushushu
Ukucima umphezulu nokucinywa kobushushu obutshatileyo kudla ngokuqhutywa ngokuthambisa okanye ukufudumeza. Iiparamitha eziphambili zobuqili bubunzima obuphambili, ubunzima bendawo kunye nobunzulu bobunzulu obusebenzayo. I-Veskers Hardy Tester okanye i-robwell ubunzima be-rockwell bunokusetyenziselwa uvavanyo lobunzima. Ukuvavanywa kwamandla oKhetho kunxulumene nobunzulu becala elicekeceke kunye nobunzima bomsebenzi. Kukho oomatshini abathathu abalukhuni babandakanyeka apha.
. Ingasebenzisa amandla ovavanyo lwe-0.5-100kg ukuvavanya umaleko onqeni onzima njengo-0.0mmm ubukhulu. Ukuchaneka kwayo kuphakama kwaye kunokwahlula-hlula amachaphaza athethwe ngamandla. Umahluko omncinci kubunzima bomphezulu, ukongeza, ubunzulu be-therter esebenzayo kwaye buchongwe ngabaphumeleleyo kwiiyunithi ezisebenza nzima okanye zisebenzisa inani elikhulu lemisebenzi yobushushu.
. Kukho izikali ezintathu ze-rockwell hardtrance ye-rought yokukhetha ukusuka. Ingavavanya iindawo ezahlukeneyo zokusebenza ezinzima ezinobunzima obunobunzima obunamandla obuchule obungaphezulu kwe-0.1mm. Nangona ukuchaneka komphezulu we-rockwell ubunzima obuqinileyo abuphakamiswanga njengabo abaphumeleleyo, kungenzeka ukuba bafezekise iimfuno zendlela yokuchonga yolawulo lomgangatho kunye nokuhlolwa kwenqanaba lokunyanzelwa kobushushu. .Bestides, ikwaneempawu zokusebenza ngokulula, ukusetyenziswa ngokulula, ixabiso eliphantsi, imilinganiselo ngokukhawuleza, kunye nokufunda ngokuthe ngqo amaxabiso obunzima. Umphezulu we-rockwell hardtrance titer unokusetyenziswa ngokukhawuleza kwaye ungayonakalisa i-of iqaqambe iimfazwe eziphathwa gadalala. Ibaluleke kakhulu ekusebenzeni kwentsimbi kunye neefektri zoomatshini. Xa unyango lobushushu obukhuselekileyo lube lukhuni lube lukhuni, i-rockwell ubunzima be-gurwell bunokusetyenziswa. Xa ubushushu obunzima ubunzima obuqinileyo bukhulu yi-0.4-0.8mm, isikali se-HRA sinokusetyenziswa. Xa unobunzulu becala elinzima xa kudlula i-0.8mm, isikali se-HRC singasetyenziswa. I-Vickers, i-Rockwell kunye ne-Superficial Rockwell amaxabiso amathathu aqhelekileyo anokuguqulwa ngokulula omnye komnye, aguqulwe abe yimigangatho, imizobo okanye amaxabiso afanelekileyo afunwa ngabasebenzisi, kwaye itafile ehambelana nayo ikwi-iso kwi-ISO yehlabathi. I-American Standard Astm kunye ne-China esekwe kwi-GB / T inikiwe.
. Xa ukulinganisa, ingqalelo kufuneka ihlawulwe kumphezulu wokugqibela kunye nobungqingqwa bemisebenzi yomsebenzi. Le ndlela yokulinganisa ayinabaphumeleleyo kwaye i-Rockwell i-titer yobuqili ichanekile, kodwa ilungele ukulinganiswa kwendawo kumzi-mveliso.
2. Unyango lobushushu ngemichiza
Unyango lobushushu lwekhemikhali kukuthintela umphezulu womgangatho wokusebenza ngeeatom zenye okanye ezininzi zekhemikhali, ngokutshintsha ukwakhiwa kwamachiza, isakhiwo kunye nokusebenza komphezulu womsebenzi. Emva kokucima kunye nokuxinana kweqondo lokushisa eliphantsi, umphezulu womsebenzi unelukhuni ephezulu kwaye unxibe ukunganyangeki. Nokunxibelelana namandla okudinwa, kwaye eyona nto iphambili kwi-coremerpiece inamandla aphezulu kunye nokuba nobunzima. Iiparamitha eziphambili zonyango lwemichiza onyango lobushushu bubunzulu becala elilukhuni kunye nobunzima bomphezulu. Umgama apho ubunzima baye khona ukuya kwi-50hrc yindlela enobungozi esebenzayo. Uvavanyo lobunzima obulukhuni lwekhemikhali lwekhemikhali luhlelwe luvavanyo olufana nobunzima bobunzima bomsebenzi obugxothiweyo. I-Veskers Hests Testers, umphezulu we-rockwell hards testers okanye i-robwell testers ze-rockwell ziya kusetyenziswa. Ubunzima obunzima bokufumanisa, kuphela ubukhulu be-nitracker hicker ticker, ngokubanzi ingabi ngaphezu kwe-0.7mm, emva koko i-rockwell ubunzima obungasetyenziswanga
3. Unyango lobushushu basekhaya
Ukuba iinxalenye zonyango lwasekhaya zifuna ubunzima obuphezulu lwendawo, ukunciphisa impangelo lobushushu kungaqhutywa ngeyona ndawo ishushu, kwaye uvavanyo lokuvavanywa kwendawo kufuneka lusebenzise ixabiso le-HRC lokuvavanya ixabiso le-HRC. Ukuba unyango lobushushu lukhuselekile ukuba lungasebenzi, umphezulu we rotwell ubunzima obungasetyenziselwa ukuvavanya ixabiso elinzima.
