Ukuthetha malunga nokunyangwa kobushushu kweengqiniba emva kokubumba

Iingqiniba zentsimbi yekhabhoni zizifakelo zemibhobho yentsimbi etshintsha indlela yemibhobho kwimibhobho yentsimbi yekhabhoni. Izinto ze-elbows ziyintsimbi, insimbi engenasici, insimbi ye-alloy, isinyithi esithambileyo, isinyithi sekhabhoni, isinyithi esingenawo isinyithi 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 yemveliso, 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.

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-grain coarse ihlanjululwa, i-hardness kunye ne-plasticity ilungelelaniswa kakuhle, kunye neempawu zomatshini ezibanzi ziphuculwe. Ngoko ke, kunoqoqosho ngakumbi ukusebenzisa i-normalizing endaweni yokucima ii-elbows ezineemfuno eziphantsi.

Ewe, oku ngasentla sisingeniso esifutshane kulwazi olufanelekileyo lwe-carbon steel elbow unyango lobushushu, enkosi ngokufunda.
