Ukuze uqonde iingenelo zemivalo yentsimbi enemisonto, ezi zigwebo zilandelayo zinokutsalwa.
1. Ukuchongwa kokwakheka kweekhemikhali
Uhlalutyo lomxholo weC, Si, Mn, P, S, njl. kwi-Rebar
Ukwakhiwa kweekhemikhali kufuneka kuhambelane ne-ASTM, i-GB, i-DIN kunye neminye imigangatho.
2. Uvavanyo lokusebenza koomatshini
Uvavanyo lwe-tensile lubonisa amandla okuqina, amandla esivuno, indawo yoxinzelelo, njl.
Rockwell okanye Vickers uvavanyo lobulukhuni.
Iikhrayitheriya zokusebenza koomatshini ezichazwe kwimigangatho ehambelanayo kufuneka zilandelwe.
3. Ukufunyanwa kwesinyithi
Jonga isampuli kwi-metallographic analyzer ukujonga iziphene kunye neesampuli ezikumgangatho ophantsi.
Ubume kufuneka bube bushelelezi, bufanane, bungabi naziqhekeza kunye nokufakwa kwamanye amazwe.
4. Jonga umgangatho wewebhusayithi.
Jonga ngokubonakalayo inkangeleko, umgangatho womphezulu, umonakalo owenziwe ngoomatshini, iintanda, izibonda, njl.
I-Ra isetyenziselwa ukufumanisa uburhabaxa bomphezulu
5. Khangela intsingiselo
Iijigs kunye nezixhobo zisetyenziselwa ukujonga iiparitha ezifana nomgangatho wesinyithi, isandi kunye nokunyamezela.
Khangela iziphene, umonakalo, ukuguqulwa, njl.
Ngokuhambelana nemigangatho yelizwe kunye nezoshishino
6. Uvavanyo olungonakalisi
Zombini umphezulu kunye nengaphakathi zivavanywa ngendlela yolwelo yokungena okanye indlela yamasuntswana ombane.
Ke ngoko, ukuba ngaba iziphumo zovavanyo ziyahlangabezana neemfuno zomgangatho woshishino zinokwenza uphononongo oluhle lwe-rebar.Oku kufuna ukusetyenziswa kwezixhobo zovavanyo ezizodwa kunye neenkqubo zovavanyo.
