Ingqele steel liqengqiwe: iimpawu, iimpawu, isicelo

steel Cold liqengqiwe (s / a) - enye yezi ntlobo uthandwayo namhlanje ngentsimbi-roll. Inani lilonke oxwebhu sentsimbi eyenziweyo liyaqhubeka umthamo. Oveliswa Nanjengoko igama layo lixela, indlela ehlelayo ebandayo. metal Ductile iphathwa xi okhethekileyo ngaphandle preheating. Iyafumaneka iifom ezimbini - iphepha ngengqele-liqengqiwe ilisuse. iimveliso Kugqityiwe unokuba ubude nobukhulu ezahlukeneyo, ngohlangothi cut kunye ucinezelo.

Iimpawu ngensimbi abandayo-wasusa

Imfuno ekhulayo for steel ebandayo-ezityikitywe ngenxa iimpawu umgangatho ophezulu ngaphezu imveliso ezishushu liqengqiwe. Ngaphezu koko, sheet metal ubukhulu 1 mm ngaphantsi inokusebenza ngokorhwebo kuphela inkqubo ebandayo. ehlelayo Cold ufakwa carbon eqhelekileyo, icarbon ezikumgangatho ophezulu, yodidi exutyiweyo eliphezulu-ingxubevange, ubushushu-ukumelana nobushushu-enganyangekiyo aluminiyamu emelana nokudliwa ngumhlwa. Le khemikhali Ukwakhiwa ngentsimbi aphathwe kugqiba iimpawu zentsimbi kunye othile yayo. Ngenxa yoko, amanqaku ezintsonkothileyo oluxonxiweyo kusetyenziswa intsimbi onekhaboni ephantsi amaxwebhu, abandayo ezityikitywe, GOST 19904-90. i emincinci metal emva kokuba eqengqele kakhulu imisela plasticity yayo, ceteris paribus.

steel Cold liqengqiwe, iveliswa 0.25-5.0 mm ubukhulu kwaye lufumaneka sheets ngobukhulu ezahlukeneyo - ukusuka 510h710 mm ukuya 1250h2500 mm. Steel 0.25-2 mm Isefu zamafu ezinokubonelelwa. Ingqele-liqengqiwe sheet steel sombane ukuvelisa mm 0,28-0,5 ubungakanani sheet engqindilili 750-1000 mm. Ngu transformer steel kwiimfuno ezibalulekileyo ubeke phambili, oko kukuthi - ixabiso mninzi obhobhozayo Imagnethi yomhlaba kunye watt ilahleko isisombululo. Kwaye kuveliswe uxwebhu umqulu sentsimbi yodidi ezibandayo ezityikitywe zesakhiwo, ingxubevange eliphezulu yodidi noshowo injongo ekhethekileyo zombane ephantsi carbon kunye lesilicon yodidi. Iveliswe kubanda ezityikitywe estrip spring, isixhobo, ngokuba iziphaluka ngemagnethi.

Iimpawu ze sheet abandayo liqengqiwe

jikelele-njongo sheet ebandayo-liqengqiwe, akhutshwa yodidi komsindo wakhe imichiza ichaza GOST 1050-88: 08ps, 08kp, 10PP, 10ps, 15 ps, 15kp, 20ps, 20kp, 25, 30, 35, 40, 45. Kuba ehlelayo abandayo ufakwa Ukubetha umgangatho amabakala steel 08U, 08kp kunye 08ps. umphezulu steel Cold liqengqiwe yi iimilo made nengqalileyo zejometri.

Ngokwahlukileyo igama layo, intsimbi abandayo saliqengqa akuthethi kusinda impatho ubushushu. Nawuphi metal ebandayo-liqengqiwe, uveliswa billet ashushu liqengqiwe.

imveliso steel abandayo wasusa

I Iphepha ebandayo-ezityikitywe kwenziwa ngeendlela ezimbini: iphepha elinye okanye roll. Xa iphepha-indlela luvelise ngentsimbi eshushu-ezityikitywe emva ehlelayo abandayo isikwe amaphepha, baye owandithumayo ngokwahlukeneyo kuqhubekeko oluphambili (annealing, eqondisa et al.).

Kwinkqubo mihla imveliso ukuze umqulu wokuzikhethela. Kulo mzekelo, zonke izigaba yokuvelisa ye x / k intsimbi imiqulu oluqhutywa iimveliso esele zenziwe yi manual okanye oluzenzekelayo cut ibe sheets. indlela Round kwenza imisebenzi bulk processing nokuhambisa, kwandisa imveliso imveliso igqityiwe, uphucula iimpawu intsimbi kunye nefom uzinzo ngenxa inkqubo yokuvelisa. Ngale ndlela yokwandisa imveliso kweemveliso ezigqityiweyo kunokwenzeka kwimimandla efanayo. Kwezinye iimeko intsimbi ebandayo-ezityikitywe ikhutshwa ngazo rolls. Kuxhomekeka inkqubo yokuvelisa ezinye amashishini umatshini-isakhiwo, kuyanceda ukucutha ubuninzi benkunkuma. Ekuvelisweni ngengqele steel liqengqiwe, imisebenzi ezinyanzelekileyo ukucocwa descaled strip eshushu-ezityikitywe, ukuziqengqa Mills ukuba (ingathityazwa okanye eqhubekayo), unyango ubushushu, ukusika, bezama.

Ukwahlula iinkalo eshushu-liqengqiwe nengqele-wasusa

metal Hot kuba lula ukusebenza. Kuba amanqaku ezenziwe ehlelayo eshushu isetyenziswa kakhulu ephantsi-grade, lilikhulu iindleko ngentsimbi. iimveliso Kugqityiwe basoloko wambu abasakhasayo zifuna unyango olongezelelweyo. Nje ngoko ke kunzima ukuba abale imida metal deformation ngexesha zokupholisa Hot geometry metal liqengqiwe, abawa ezahlukeneyo (ubukhulu obungalinganiyo, izitenxo emancamini kunye iikona).

indlela Cold-qikeka kwenza kube lula ukugcina ngqo efunekayo iimveliso imilinganiselo. Umphezulu of a ogudileyo, ubukhulu efanayo enjalo liqengqiwe, ngoko ke unyango imveliso yokugqibela uyacutheka, kwaye maxa wambi nkqu efunekayo. Ngenxa isakhiwo bomzi, metal abandayo liqengqiwe ixesha elide kakhulu yaye uneempawu ngcono lekhefu, ayeguqa, elula. Ukuze ze amabakala eziphakamileyo ngentsimbi.

Ukusebenza steel abandayo-wasusa

metal Cold-ezityikitywe isetyenziswa kumacandelo amaninzi: kwi uzinzo izithuthi, oomatshini ukuba izakhiwo, izixhobo mveliso, iindawo umatshini, ulwakhiwo, ishishini elihambisayo, ukuveliswa zasendlini.

3 steel ebandayo wabulala - enye indleko kuyabiza. Ubuncinane isiqulatho oxygen kuphucula ukufana lwesakhiwo, plasticity kunye nokumelana. Isetyenziswa izakhiwo nzima intsimbi kunye nezinto umthwalo-langa, iimilo zezakhiwo, izinto ipipi ezifakwe. steel Cold-ezityikitywe isetyenziswa ekwenziweni kumacandelo ekucaca ukuba ukuhlasela thermal nemichiza.
