Iinkcukacha zeMveliso

Iithegi zeMveliso

Umbhobho wentsimbi ochanekileyo owenziwe ngokubanda ochanekileyo luhlobo olutsha lombhobho wentsimbi, olona phawu luphambili luchanekileyo.Ngokuqhelekileyo imveliso ye-roller-roller kunye ne-three-roller mill yeenkqubo ezimbini zemveliso, imveliso ye-roller ye-three-roller ye-cold rolled seamless steel tube precision iphezulu, inokulawulwa ngaphakathi kwesilika embalwa, kodwa ixabiso liphezulu kakhulu. -Izityhubhu zentsimbi ezichanekileyo ezitsalwa ngokubanda ezichanekileyo zokugcina intsimbi, ukuphucula ukusebenza kakuhle, ukonga amandla. ukugqiba, ukujikeleza, ukuthe tye, kunokonga kakhulu iiyure zoomatshini, ukuphucula ukusetyenziswa kwezinto, ngelixa unceda ukuphucula umgangatho wemveliso.

Iindlela eziphambili zokubanda zombhobho wentsimbi ngumzobo obandayo kunye nendlela ebandayo yokuqengqeleka.Kwiminyaka yakutshanje, kunye nophuhliso lwenzululwazi kunye nobuchwepheshe, kunye nophuhliso lwendlela ebandayo ejikelezayo, ngale ndlela inokuvelisa ububanzi obukhulu, iityhubhu eziqengqelekayo ezichanekileyo eziphezulu kunye neetyhubhu eziqengqelekayo ezinecandelwana eliguquguqukayo.Ukusetyenzwa okubandayo kombhobho wentsimbi izinto ezikrwada kunokuba ngumbhobho wentsimbi ongenamthungo oshushu nawo unokudityaniswa nombhobho.Isici esiqhelekileyo sendlela yokucubungula ebandayo yombhobho wensimbi kukuchaneka komgangatho ophezulu, uburhabaxa obuhle bomgangatho, unokuvelisa kakhulu (ukuya kuthi ga kwi-0.05 ~ 0.01mm) iityhubhu ezinodonga olucekeceke kwaye zicoleke kakhulu (ububanzi ukuya kuthi ga kwi-0.3 ~ 0.1 mm) i-capillary. imibhobho.Imibhobho yentsimbi engenamthungo yimibhobho enemingxuma enqamlezileyo, esetyenziswa ngobuninzi njengemibhobho yokuthutha ulwelo, njengemibhobho yokuthutha ioli, igesi yendalo, igesi, amanzi kunye nezinto ezithile eziqinileyo.Xa kuthelekiswa nentsimbi eqinileyo efana nentsimbi ejikelezayo, umbhobho wensimbi ukhaphukhaphu kubunzima xa ukugoba kunye nokuqina kwe-torsional kuyafana, kwaye iyintsimbi ye-economic cross-sectional steel, esetyenziswa ngokubanzi kubunjineli bemibhobho.

Umboniso weMveliso

Ukukhuthazwa kunye nokusetyenziswa kweetyhubhu zentsimbi ezichanekileyo ezichanekileyo ezigcinwe ngokubanda ukuze kugcinwe isinyithi, ukuphucula ukusebenza kakuhle, ukugcina amandla. ukugqiba umphezulu ongqongqo, wangaphakathi nangaphandle, ukujikeleza, ukuthe tye kulungile, kunokonga kakhulu iiyure zokulungisa oomatshini, ukuphucula ukusetyenziswa kwezinto, ngelixa unceda ukuphucula umgangatho wemveliso.

Umzobo wenkqubo yokuvelisa

Imveliso :Inkqubo ejikelezileyo ityhubhu ayinanto → ukufudumeza → ukugqobhoza → ukuqengqeleka okuqengqelekayo okuqengqelekayo okuqengqelekayo okuqengqelekayo , ukuqengqeleka okuthe gqolo okanye ukukhupha → ukususwa kwetyhubhu → ubungakanani (okanye ukunciphisa) → ukupholisa → ukuqondisa → uvavanyo lwe-hydrostatic (okanye ukufunyaniswa kwesiphene) → ukuphawula→ ukugcina umbhobho wentsimbi ongenamthungo. eyenziwe ngentsimbi yentsimbi okanye izikhala zetyhubhu eziqinileyo ngokugqobhoza ukwenza iityhubhu ze-capillary, kwaye emva koko zishushu-ziqengqeleke, ziqengqeleke zibandayo okanye zitsalwe ngokubanda.
