Lub sab sauv thiab nqes dej ntawm kev lag luam aluminium dov kev lag luam kuj tseem qhia txog cov yam ntxwv ntawm cov pyramid faib: cov kab hluav taws xob kub dov muaj peev xwm ntau lawm ib kab (feem ntau 100, 000 tons mus rau ntau pua txhiab tons) thiab tsawg dua cov kab ntau lawm; qhov nruab nrab-kwj txias-dov txuas muaj ib qho me me ib kab ntau lawm (feem ntau (100,000} tons), nrog rau ntau cov kab ntau lawm; ib chav tsev tsim muaj peev xwm ntawm cov ntawv hlau dov txuas yog me dua , tsuas yog ob peb txhiab tons mus rau kaum txhiab tons.
Yog li ntawd, qee lub tuam txhab muaj kev tsim kho me me thiab feem ntau tsis muaj cov khoom siv hluav taws xob kub dov lossis casting thiab dov cov kab ntau lawm, thiab lawv yuav blanks rau kev ua haujlwm rov qab.
Tam sim no, cov kev sib txuas hauv kev lag luam saw nrog nruj tsim muaj peev xwm yog kub dov thiab ntawv ci dov. Ua ntej tshaj plaws, txij li kev nthuav dav ntawm cov peev txheej tsim tau yog tsom rau hauv qhov sib txuas ntawm cov khoom siv txias txias, qhov tsis sib xws ntawm cov khoom siv thiab kev thov hauv qhov sib txuas txias dov yog me dua, thiab cov peev txheej sab saud yog qhov loj thiab qhov ntsuas ntawm ib kab ntau lawm yog qhov loj, yog li. kev lag luam nqis peev tsawg dua thiab ceev faj nyob rau sab saud.
Thib ob, nyob rau hauv cov nqe lus ntawm daim ntawv thov davhlau ya nyob twg, qhov kev thov rau txhuas ntawv ci yog muaj zog, yog li cov ntawv ci dov txuas kuj tseem nyob rau hauv cov khoom luv luv (vim tias tsis muaj kev txheeb xyuas meej ntawm cov peev txheej ntau lawm thiab cov ntaub ntawv ntawm cov khoom sib txawv, cov ntaub ntawv hauv kab lus no. yog cov kwv yees kwv yees).
