Ipleyiti yentsimbi ye-A36yenye yentsimbi eqhelekileyo, ukhe wazi ngayo?
Ngoku ndilandele kuhambo lokufumanisa malunga nentsimbi ye-A36!
I-ASTM-A36 ipleyiti yensimbi yintsimbi yaseMelika esemgangathweni ye-carbon structural eyenziwe ngokwemigangatho ye-ASTM.I-A36 carbon steel coil ukwakheka kweekhemikhali kunye neempawu zomatshini zihambelana nemigangatho ye-ASTM yaseMelika.Ukuqengqeleka okushushu kusetyenziswa njengesiseko sonikezelo, kwaye ubukhulu bemveliso buphakathi kwe-2mm kunye ne-400mm.Iimfuno zobugcisa zamacwecwe ensimbi zinokubhekisa kumgangatho we-A578 waseMelika wokufumanisa isiphene.Kukho amanqanaba amathathu okubona iziphene A, B, C kunye nenqanaba le-A435 lokubona iziphene.Ukusebenza kwentsimbi ye-A36 eshushu eqengqelekayo kuzinzile kwimveliso.Ipleyiti yentsimbi ye-A36 eshushu eshushu ineempawu ezintle zoomatshini, ukusebenza kwe-welding kunye nokumelana nomhlwa, kwaye isetyenziswa ngokubanzi kulwakhiwo, iibhulorho, ukwenziwa koomatshini kunye namanye amacandelo.
I-ASTM-A36 luhlobo lwentsimbi yekhabhoni enemichiza exutywe kakhulu nekhabhoni (C), i-silicon (Si), i-manganese (Mn), i-phosphorus (P), isulfure (S) kunye nezinye izinto.Phakathi kwabo, i-carbon yinto ephambili, kwaye umsebenzi wayo kukwandisa amandla kunye nobunzima bensimbi.I-silicon kunye ne-manganese zizinto ezidibanisayo ezinyusa ngakumbi amandla kunye nokuqina kwentsimbi.Iphosphorasi nesalfure zizinto ezingacocekanga.Ubukho babo buya kunciphisa ukuqina kunye nokuxhatshazwa kwe-corrosion yensimbi, ngoko umxholo wabo kufuneka ulawulwe ngokungqongqo ngexesha lenkqubo yokuvelisa.
