Ukuqulunqwa kwemichiza
I-Carbon steel plate ye-Q235D, i-high-high-high-high-steel plate isetyenziswa ngokubanzi ekwakheni, kwimoto, ekwakheni iinqanawa, oomatshini kunye nezixhobo kunye namanye amashishini amaninzi, kodwa ipleyiti yensimbi ephezulu kufuneka ikhethwe ngokufanelekileyo. Okokuqala, ibakala liphezulu kakhulu, oku kuthetha ukuba ixabiso liya kuba phezulu ngenxa yeendleko eziphezulu zokuvelisa. Okwesibini, inqanaba eliphantsi lithetha ukuba ukusebenza kokhuseleko akukho kumgangatho. Okwesithathu, inkcazo yamacwecwe ensimbi ephezulu kufuneka ikhethwe ngokuhambelana ngokungqongqo kwimidwebo yokuyila. Okwesine, kucetyiswa ukuba uthenge izixhobo ezikhethekileyo zorhwebo ukuvavanya iiplati zetsimbi eziphezulu.

Inokuqina okulungileyo. Ngokulawula ngokungqongqo ukubunjwa kweekhemikhali, ukunciphisa umxholo wezinto ezinobungozi kwi-Q235D carbon steel plate, kunye nokukhetha iimeko ezifanelekileyo zokunyanga ukushisa, i-NM360 ipleyiti yensimbi inobunzima obuhle. Ke ngoko, iinxalenye zesakhiwo ezinokuthembeka okuphezulu zinokwakhiwa ngokuhambelana nokungaphumeleli kwe-brittle yeendawo zokunxiba. Icwecwe lentsimbi ye-carbon ye-Q235D ithatha itekhnoloji ephezulu kunye nezixhobo, idityaniswe nolawulo oluphezulu nolwenzululwazi lobugcisa, ukuze izinto kunye nokumila kwemveliso zifane kwaye zihle.
I-S355J2 ipleyiti yensimbi ye-Q235D ye-carbon steel plate rolling yinkqubo elawulwayo. Kwinkqubo yokujikeleza, ukushisa kwe-ingot rolling yi-1000-1050 ° C; Inqanaba lokuqala lithatha inkqubo yokunciphisa isantya esikhulu sokunciphisa, inqanaba eliphezulu lobushushu li-950-1000 ° C, isantya sokuqengqeleka si-1.6-2.0m //s, inqanaba elilodwa lokunciphisa i-Q235D carbon steel plate I-15-20%, kunye nezinga lokunciphisa i-cumulative yi-40-45% ukuqinisekisa ukuguqulwa okupheleleyo kwe-ingot. Kwinqanaba lokuqala, iqondo lokushisa eliqalayo liyi-910-930 °C, kwaye ubushushu bokugqiba ngu-≤ 870 °C.
