Ngophuhliso olukhawulezayo lweshishini leoli laseTshayina, imfuno yensimbi ephezulu ikhula, kwaye intsimbi ephezulu kufuneka icinywe, kwaye ke uphononongo lokucinywa kwentsimbi lubaluleke kakhulu.China Heavy Machinery Research Institute iye yaphuhlisa "dip quenching + ukutshiza yangaphakathi + spin" yaye "ngaphandle jet ishawa yangaphakathi + spin" iinkqubo ezimbini, kunye nophando kunye nophuhliso enxulumene ukucima umgca, kwaye iphumelele iziphumo ezilungileyo.Zombini inkqubo yokucima ineempawu zayo, ishawari yangaphandle ngaphakathi kwijethi yokucima umgca wokuvelisa ilungele imibhobho yeoli ye-oyile, i-oyile ye-oyile, i-drill pipe quenching, inceda ngakumbi kwityhubhu yentsimbi yokucima udonga ngokubanzi;ukuntywiliselwa quenching umgca imveliso ilungele uthelekiso ubukhulu eludongeni Omkhulu iyonke lukhuni ukusebenza eliphezulu ityhubhu ashinyeneyo-engqingqwa, kunye neemveliso zayo ikakhulu zisetyenziswa kukhuselo lwesizwe, amandla enyukliya, i-oyile negesi kunye namashishini iimoto.

Ukuntywiliselwa ukucima umgca wemveliso
Izixhobo zokucima zasekhaya ezisetyenziswayo ngoku, kukho iziphene zetyhubhu ezishinyeneyo, ezinje (1), ukugoba kombhobho ongqindilili olucima ngokulula, ukuthe tye, ukungqukuva okungalunganga, ukuya kubunzima obulandelayo bokubunjwa;(2) umbhobho wangaphakathi nangaphandle awunakucinywa, okubangela ukuba umxholo womzimba kaMarkov uphantsi, ubulukhuni obungalinganiyo;(3) iindleko eziphezulu zokusebenza, ukhuseleko olubi.Ukuphendula kwezi ntsilelo, isibhedlele esizimeleyo sophando kunye nophuhliso, iiseti ezipheleleyo zokwenza ukusetyenziswa kokuqala kwehlabathi "kokucima ukuntywiliselwa + Ukujikelezisa + ukutshiza kwangaphakathi" ukucima umbhobho wentsimbi ubukhulu bodonga ngaphezu kwe-20 mm ukusuka kumgca wokuntywiliselwa wokucima ukucima umgca wemveliso.Indlela yenkqubo yile: izixhobo zokufudumeza zentsimbi eqinisiweyo → igeyiji yokufika ebekwe kwilifti ijikeleza ngokukhawuleza ithetha ukucinezela kuthetha ukucinezela umbhobho wentsimbi wokuqhuba ivili → ujikeleze umbhobho wokuphakamisa ojikelezayo ojikelezayo ukuqhuba isakhelo sentsimbi umqadi wokuntywiliselwa ngokukhawuleza ocimayo emanzini → ngaphakathi kwesitshizi. umlomo wombhobho oya ngaphakathi wenaliti yombhobho wentsimbi → isiphelo sokucima, ngaphakathi kwendawo yokutshiza → malunga nokuphakamisa umbhobho uya kunyuka imiqadi yesakhelo sentsimbi → skrola ukumisa isixhobo sokutyisa kwisixhobo sokutyisa ngebhloko-ngokujika kwingcambu yamanzi angenanto. isibiyeli sombhobho → Amanzi angenanto athetha ukuphakamisa enye incam yombhobho ziphakanyiswe ngakumbi ukuvuthela umoya ocinezelweyo wokucima amanzi → amanzi → umbhobho wokuhambisa umbhobho onyathelayo ngaphakathi kumbhobho othuthwa ngokuthe chu ukuya kwiirola zefidi → intsimbi epheleleyo eqina.Le yunithi ukucima ukucima ukucima okokuqala usebenzisa "ukuntywiliselwa quenching + Jikelezisa + isitshizi sangaphakathi" iteknoloji entsha ubukhulu ubukhulu, ityhubhu eshinyeneyo-engqindilili jikelele quenching ukusombulula ubukhulu obukhulu-engqingqwa umbhobho bend quenching quenching, ukucima iingxaki zobugcisa ongenakungena;Siphumelele ezi ziphumo zilandelayo ezibalulekileyo: (1) Ngenxa yomgangatho opheleleyo wombhobho wamanzi, ukujikeleza kwesantya esiphezulu, inkxaso yokuncedisa amanqaku amaninzi, ukwenzela ukuba kuphuculwe kakhulu ukuthe tye kwentsimbi, ngaphantsi kwe-2 mm / m, ukuhlangabezana neemfuno imveliso.(2) usebenzisa umsebenzi wokujikelezisa ngaphakathi komlomo wesitshizi esihambayo, ukunciphisa umbhobho ovality intloko ehambisa ubungakanani bombhobho.(3) Ngokucinywa kwentshukumo ngaphakathi kwenkqubo yokucima bhetyebhetye ngakumbi, iipropathi ezifanayo zoomatshini zentsimbi, emva kokucima isantya sokuguqulwa kwemartensite ngaphezulu kwama-90%, nokuba ngama-95%, ukuqina kunye nolwalathiso lobungqimba lwempazamo yombhobho wentsimbi wobude obugcweleyo ≤ 3 HRC.

"Ukutshiza + ishawari yangaphandle + spin yangaphakathi" inkqubo yokucima.
Le nkqubo incinane kakhulu eludongeni ubukhulu bombhobho.Iziko lentsimbi eliqinileyo elifudumezelelwe malunga ne-1000 ℃, i-roller feed kwisikhundla esilindelekileyo, isixhobo sokutyisa ukuphakamisa intsimbi ukuyifaka kwi-rotation ecothayo ithetha ukujikeleza kwamavili enkxaso, uxinzelelo olubekwe kwi-rock yokutshiza ukuqinisa ngokukhawuleza kuthetha ukucinezela umbhobho, i-rotary drive ithetha ukujikeleza ngokukhawuleza umbhobho wentsimbi ojikelezayo, umbhobho wentsimbi ubekwe ngqo phezu komphezulu ongaphandle wombhobho wokugalela kwisitshizi sombhobho wangaphandle ofanayo, ngelixa isitshizi sithetha ukufakelwa kumbhobho ekupheleni kodonga lombhobho ukuya kwintloko yokutshiza.Ngaloo ndlela iindawo zangaphakathi nangaphandle zombhobho wensimbi ziye zacinywa ngokufanayo.
