Q345B Square Tube
Q345B umuyoboro wa kare, 16Mn kare Imiyoboro y'icyuma y'urukiramende, imiyoboro itagira ingano iringaniye y'ibyuma n'ibindi bicuruzwa bya kare.
Umuyoboro wa Q345B ukorwa ukurikije ibipimo ngenderwaho byigihugu GBT 6728-2002 bikonje bikonje byubatswe igice cyicyuma kubunini, imiterere, uburemere no gutandukana kwimiterere.Ikozwe muri Q345B ya strip nyuma yo gutunganya no kuzunguruka.Umuyoboro wa Q345B ukozwe mu bikoresho bya Q345B (ibivanze bito), bitandukanye cyane na tari kare isanzwe mu bikoresho fatizo (Q195, Q215, Q235).Mubisanzwe, Q345B ikuramo ibyuma (alloy alloy) irapakururwa..Uburebure busanzwe ni metero 6, kandi ubwinshi bwa metero 12 burashobora gutunganywa ukurikije ibyo abakiriya bakeneye.Mubisanzwe, ubunini buto ni ibice 50 kuri buri paki, naho ubunini ni ibice 4 buri kimwe kandi uburemere bugenzurwa kuri toni 3.Imiyoboro ya Q345B ahanini ni 80MM * 80MM-500MM * 500MM mubisobanuro binini mububiko, kandi ubunini ni 3MM-16MM.
Q345B kare ya tube itagira ikidodo kandi irasudwa
Q345B itagira ingano ya kare igizwe no gukuramo Q345B itagira uruziga.
Q345B ya kare ya plastike
Plastike bivuga ubushobozi bwibikoresho byibyuma byo gukora plastike (deformasiyo ihoraho) bitarangiritse munsi yumutwaro.
Q345B kare kare
Gukomera ni igipimo cy'ubukomezi bw'ibyuma.Uburyo bukoreshwa cyane mugupima ubukana mubikorwa nuburyo bwo gukomera bwa indentation, bukoresha indenter yimiterere ya geometrike kugirango ukande hejuru yibikoresho byuma kugirango bipimishe munsi yumutwaro runaka, kandi agaciro gakomeye kagenwa ukurikije urwego rwo kwerekana.
Uburyo bukunze gukoreshwa burimo ubukana bwa Brinell (HB), ubukana bwa Rockwell (HRA, HRB, HRC) na Vickers gukomera (HV).
Q345B umuyoboro wa kare ni igice cya kare cyuzuye urumuri ruto rukikijwe n'icyuma, kizwi kandi nk'icyuma gikonjesha.Nicyuma cyigice gifite ubunini bwa kare buringaniye nubunini bukozwe muri Q345B bishyushye cyangwa bikonje bikonje cyangwa igiceri nkibikoresho fatizo, bikozwe no kugonda ubukonje hanyuma bigasudwa no gusudira kenshi.Usibye kubyimbye kwubukuta bwurukuta rwubushyuhe bushyushye burenze uburebure bwurukuta rwa kare, ubunini bwinguni hamwe nuburinganire bwurugero bwageze cyangwa burenze urwego rwurwanya rusudira rukonje rufite imiterere ya kare.
Q345B ikoreshwa rya kare
Imiyoboro ya Q345B isanzwe ikoreshwa mubwubatsi, gukora imashini, imishinga yo kubaka ibyuma, kubaka ubwato, gushyigikira ingufu z'izuba, ubwubatsi bw'ibyuma, ubwubatsi bw'amashanyarazi, inganda z'amashanyarazi, imashini zikoreshwa mu buhinzi n’imiti, urukuta rw'umwenda w'ikirahure, chassis y'imodoka, ibibuga by'indege, n'ibindi.
Q345B kare ya pine ishami ryuburemere bwo kubara: impande 4 zongeweho * uburebure * 0.00785 * uburebure
Q345B umuyoboro urukiramende ushyigikira formula yo kubara uburemere: (uburebure bwuruhande + uburebure bwuruhande) * 2 * 0.00785 * uburebure bwurukuta * uburebure
