Ibha yentsimbi yeAngle SS400 JIS
Xa kuthengwa kwaye kusetyenziswa olu hlobo lwe-angle bar, kubaluleke kakhulu ukuqonda iimpawu zayo eziphathekayo kunye neenkcukacha.
Ukuqulunqwa kwemichiza
Ukubunjwa kweekhemikhali ze-SS400 yentsimbi ye-angle bar kufuneka ihambelane nemimiselo ye-JIS G 3112. Amacandelo ayo aphambili aquka isinyithi (Fe), i-carbon (C), i-silicon (Si), i-manganese (Mn) kunye nezinye izinto. Phakathi kwabo, umxholo wekhabhoni kufuneka ube phakathi kwe-0.18% -0.28%, umxholo we-silicon kufuneka ube phakathi kwe-0.12% -0.30%, kwaye umxholo we-manganese kufuneka ube phakathi kwe-0.70% -1.00%. Ukongezelela, intsimbi ye-angle kufuneka iqulethe izinto ezithile ze-phosphorus (P) kunye nesulfure (S) ukunyusa ubunzima kunye namandla.
Iimpawu zomatshini we-SS400 yentsimbi yeprofayili kufuneka ihambelane nemigaqo ye-JIS G 3112. Amandla ayo okuqina (σb) akufanele abe ngaphantsi kwe-400N/mm², kwaye amandla ayo okuvunwa (σs) akufanele abe ngaphantsi kwe-240N/mm². Kwangaxeshanye, i-elongation (δ) yentsimbi yentsimbi egobileyo ayifanele ibe ngaphantsi kwama-22%. Ezi zixhobo zomatshini ziqinisekisa ukuba i-SS400 angle yensimbi inomthwalo ophezulu wokuthwala umthwalo kunye nokuqina kwiimeko ezahlukeneyo zesicelo.

Ukusebenza kwenkqubo
I-angle ye-SS400 elinganayo inenkqubo elungileyo yokusebenza kwaye ingasetyenziselwa ukugoba, ukolula, ukucheba, isitampu kunye neminye imisebenzi yokucubungula. Kwangaxeshanye, olu hlobo lweeprofayili zentsimbi ezishushu eziqengqelekayo zinokusebenza kakuhle kwe-welding kwaye zinokuhlangabezana neemfuno ezahlukeneyo zokuwelda. Ngexesha lokucubungula, kufuneka kuhlawulwe ingqalelo ekulawuleni izinga lokushisa kunye nesantya sokupholisa ukuphepha ukuqhekeka kunye nokuguqulwa kwentsimbi ye-angle.
Ukunyangwa kokuMhlwa
Intsimbi ye-engile ye-SS400 inoxhathiso oluthile lokutya, kodwa ithanda ukuba nomhlwa kwiindawo ezifumileyo. Ukuze kuphuculwe ukuxhathisa kwe-corrosion, umphezulu wentsimbi ye-angle unokugqunywa ngoluhlu lwepeyinti echasene ne-rust. Ukongezelela, ngexesha lokuthutha kunye nokugcinwa, intsimbi ye-angle kufuneka igcinwe yomile kwaye icocekile ukuphepha ukubonakaliswa kwexesha elide kumswakama.
Ngamafutshane, intsimbi yaseJapan esemgangathweni ye-SS400 yintsimbi ekumgangatho ophezulu esetyenziswa ngokubanzi kulwakhiwo oluhlukeneyo, iibhulorho, iinqanawa, iimoto kunye nezinye iindawo. Kubaluleke kakhulu ukuqonda iimpawu zayo eziphathekayo kunye neenkcukacha xa kuthengwa kwaye kusetyenziswa olu hlobo lwentsimbi ye-angle. Ngethuba lokusetyenziswa, ingqalelo kufuneka ihlawulwe ekugcinweni nasekugcinweni ukuze kuqinisekiswe ukhuseleko kunye nobomi benkonzo.
