Umahluko phakathi kokuphosa ibhola yentsimbi kunye nebhola yentsimbi yokubumba

1. Ibhola yentsimbi ephosayo: intsimbi ye-chromium ephantsi, intsimbi ye-chromium ephakathi, intsimbi ye-chromium ephezulu kunye nentsimbi ye-chromium ephezulu kakhulu (Cr12%-28%).

2. Ibhola yentsimbi yokuyila: intsimbi ye-alloy ekhabhoni ephantsi, intsimbi ye-alloy ekhabhoni ephakathi, intsimbi ye-manganese ephezulu kunye nebhola yentsimbi ye-chromium molybdenum alloy enqabileyo yomhlaba:

Ngoku ke loluphi uhlobo lwebhola yentsimbi olungcono? Ngoku makhe sihlalutye:

1. Isalathisi somgangatho wentsimbi ye-chromium ephezulu: umxholo we-chromium ungaphezulu kwe-10%, umxholo wekhabhoni kwi-1.80%-3.20% ubizwa ngokuba yi-chromium ephezulu, iimfuno zomgangatho wesizwe wobunzima bebhola ye-chromium ephezulu (HRC) kufuneka zibe yi-≥ 58, AK ≥ 3.0J/ cm ixabiso lempembelelo ye

2. Isalathisi somgangatho wentsimbi ye-chromium ephantsi: nge-0.5% ~ 2.5%, umxholo wekhabhoni kwi-1.80% -3.20% ubizwa ngokuba yi-low chromium steel, iimfuno zobunzima bentsimbi ye-chromium ephantsi yesizwe (HRC) kufuneka zibe yi-≥ 45, AK ≥ 1.5J/ cm ixabiso lempembelelo ye-2, iRolling Ball ukuqinisekisa umgangatho webhola yentsimbi ye-chromium ephantsi, ukufudumala okuphezulu okanye unyango lokuguga lokungcangcazela (ukuze kupheliswe uxinzelelo lokuphosa, njengenjongo) yomphezulu webhola yentsimbi ubomvu obumnyama ukubonisa ukuba imveliso iye yaba lunyango lokufudumala okuphezulu, njengoko umphezulu webhola yentsimbi umbala wentsimbi ubonisa imveliso ngaphandle kokufudumala.

3. Isalathisi somgangatho webhola yentsimbi eyenziweyo: ene-0.1% ~ 0.5% (ibhola yentsimbi eyenziweyo ngaphandle kwe-chromium), umxholo wekhabhoni ongaphantsi kwe-1% kunye nebhola yentsimbi eyenziweyo enobushushu obuphezulu bokuvelisa, ubunzima bomphezulu webhola yentsimbi eyenziweyo (HRC) ≥ 56 (nangona inokufikelela ngaphezu kokucima umaleko we-15 mm okanye ngaphezulu), ubunzima be-core because of steel steel ball material harden ability buhlala bungama-30 degrees kuphela. Kwiimeko eziqhelekileyo, ibhola yentsimbi eyenziweyo ngonyango lokucima amanzi, izinga lokwaphuka kwebhola yentsimbi eyenziweyo liphezulu.

4. Uthelekiso lokumelana nokuguguleka: intsimbi ye-chromium ephezulu kakhulu > intsimbi ye-chromium ephezulu > ibhola yentsimbi ye-chromium ephakathi > intsimbi ye-chromium ephantsi > ibhola yentsimbi eyenziwe ngomgunyathi.

Izinto zebhola yentsimbi engagugiyo:

Umxholo weChromium yi-1% - 3% kwaye ubunzima beHRC ≥ 45. Lo mgangatho webhola yentsimbi engagugiyo ubizwa ngokuba yibhola ye-alloy ye-chromium ephantsi. Iibhola zeChromium eziphantsi zisebenzisa i-intermediate frequency electric furnace, i-metal mold okanye i-sand casting mode. Ukusebenza kwayo kufanelekile kwezinye iimayini ze-metallurgical, i-slag kunye nezinye izimboni, ezichanekileyo kancinci kwaye zingasetyenziswa kakhulu.

Umxholo we-chromium yebhola yentsimbi engagugiyo yi-4% ukuya kwi-6% kunye nobunzima be-HRC ≥ 47. Lo mgangatho ubizwa ngokuba ziibhola ze-alloy ze-multi-element, eziphezulu kunentsimbi ye-chromium ephantsi ebhekisa kumandla kunye nokumelana nokuguguleka. Umxholo weChromium yi-7% - 10% kwaye ubunzima be-HRC ≥ 48 ziibhola ze-chromium alloy cast, ezisebenza ngazo kunye nezinye izinto ziphezulu kunebhola yentsimbi ye-alloy ezininzi.

Umxholo we-chromium yebhola yentsimbi engagugiyo ≥ 10% – 14% kunye nobunzima be-HRC ≥ 58. Iibhola ze-chromium alloy cast luhlobo lwebhola yentsimbi engagugiyo enexabiso eliphezulu elisebenzayo kunye nokusebenza kakuhle kweendleko kwimarike yangoku. Uluhlu lwesicelo sayo lubanzi kwaye isetyenziswa kwi-metallurgy, isamente, amandla obushushu, i-flue gas desulfurization, izixhobo zemagnethi, iikhemikhali, ipompo yodaka lwamanzi amalahle; ke ngoko, ibhola, umgubo ocolekileyo, i-slag, uthuthu oluphaphazelayo, i-calcium carbonate kunye nomzi-mveliso wesanti ye-quartz. Umsebenzi wayo ugxininiswa ngakumbi kumzi-mveliso wesamente, onokunyusa imveliso kwaye unciphise ukusetyenziswa kwamandla.
