Iingqiniba zentsimbi yekhabhoni zizifakelo zemibhobho yentsimbi etshintsha indlela yemibhobho kwimibhobho yentsimbi yekhabhoni.Izinto ze-elbows ziyintsimbi, insimbi engenasici, insimbi ye-alloy, isinyithi esithambileyo, intsimbi ye-carbon, isinyithi esingenawo i-ferrous kunye neeplastiki, njl.Ingqiniba engama-45°, i-90° ingqiniba kunye ne-180° ingqiniba Iintlobo ezintathu zeengqiniba zixhaphake kakhulu, kunye nezinye iingqiniba ezingaqhelekanga ezifana ne-60° nazo zibandakanyiwe ngokweemfuno zeprojekthi.Ngokwenkqubo yokuvelisa, inokwahlulwa ibe: i-welding elbow, stamping elbow, push elbow, casting elbow, etc. Sonke siyazi ukuba xa kuyilwa kunye nokuvelisa i-carbon steel elbows, iimpawu zomatshini ze-carbon steel elbows kufuneka ziqwalaselwe.Ngoko ke, indlela yokuphucula ukuqina kwe-carbon steel elbows?Emva kokuthetha oko, kufuneka sithethe ngenkqubo yonyango lobushushu.Masifunde malunga nonyango lobushushu beengqiniba ze-carbon steel.
Okokuqala, kutheni i-carbon steel elbows ifuna unyango lobushushu?Xa kuziwa ekuphuculeni iimpawu zomatshini, sonke siyazi: njengenxalenye yenkqubo yokubhobhoza, ubunzima be-elbow akufanele bube buphezulu kakhulu, ubunzima obuphezulu abukwazi ukugcina amandla okuguqula, kwaye kulula ukuphuka;iplastiki ayilunganga kakhulu, ngokusetyenziswa kwexesha.Ngokunyuka kwe-, i-deformation ye-elbow iya kuqinisa ngokuthe ngcembe, ukunciphisa ukuzinza kwenkqubo yokubhobhoza.Unyango lobushushu yinkqubo ekhoyo yokufumana ukomelela okwaneleyo, ubulukhuni kunye nokuqina kweplastiki.

Kwaye ukuqheleka kunokusombulula le ngxaki kakuhle kakhulu.I-normalizing yindlela yonyango lobushushu apho i-elbow ecinezelekileyo ishushu ngaphezu kobushushu obubalulekileyo kwaye ipholile emoyeni.Ngethuba le nkqubo, isakhiwo se-martensite esingalinganiyo siya kuguqulwa ngokuthe ngcembe sibe yi-uniform austenite structure.Kule nkqubo, I-culprit of brittleness and hardness - i-cementite e-reticulated iyanyamalala ngobuninzi obukhulu, i-grains coarse ihlanjululwa, i-hardness kunye ne-plasticity ilungelelaniswa kakuhle, kunye neempawu zomatshini ezibanzi ziphuculwe.Ke ngoko, kunoqoqosho ngakumbi ukusebenzisa i-normalizing endaweni yokucima iingqiniba ngeemfuno eziphantsi.
Ewe, oku ngasentla sisingeniso esifutshane kulwazi olufanelekileyo lwe-carbon steel elbow unyango lobushushu, enkosi ngokufunda.
