Square chitoliro ndi dzina lalikulu chitoliro ndi amakona anayi chitoliro, ndiye chitsulo chitoliro ndi wofanana ndi wosiyana mbali utali. Amapangidwa ndi chitsulo chopindika pambuyo pochiza. Nthawi zambiri, chitsulo chamzerewu chimatulutsidwa, chopangidwa, chophwanyika komanso chowotcherera kuti chipange chitoliro chozungulira, kenako ndikuchikulungitsa mu chitoliro chamzere, kenako ndikudula mu utali wofunikira.
Malinga ndi kamangidwe kameneka, machubu apakati amagawidwa kukhala machubu otentha opindika opanda msokonezo, machubu ozizira osasunthika osasunthika, machubu akunja opanda msoko ndi machubu akulu akulu.
The welded lalikulu chitoliro chagawidwa mu
1. Malinga ndi ndondomeko - arc kuwotcherera lalikulu chubu, kukana kuwotcherera lalikulu chubu (mkulu pafupipafupi ndi otsika pafupipafupi), mpweya kuwotcherera lalikulu chubu ndi ng'anjo kuwotcherera lalikulu chubu
2. Malinga ndi weld - molunjika welded lalikulu chitoliro ndi ozungulira welded lalikulu chitoliro.
Gulu lazinthu
Machubu a square amagawidwa kukhala machubu wamba a carbon steel square ndi low alloy square chubu malinga ndi zinthu.
1. Wamba mpweya zitsulo anawagawa Q195, Q215, Q235, SS400, 20 # zitsulo, 45 # zitsulo, etc.
2. Zitsulo zotsika za alloy zimagawidwa mu Q345, 16Mn, Q390, St52-3, etc.
Zopanga muyeso classification
Machubu a square amagawidwa kukhala masikweya machubu adziko lonse, machubu amtundu wa Japan, machubu aku Britain masikweya, machubu aku America masikweya, machubu amtundu waku Europe ndi machubu omwe siakuluakulu molingana ndi miyezo yopangira.
Gawo la mawonekedwe

1. Gawo losavuta lalikulu chubu: chubu lalikulu, chubu lalikulu la rectangular.
2. Square chubu ndi gawo zovuta: duwa zooneka lalikulu chubu, lotseguka lalikulu chubu, malata lalikulu chubu ndi wapadera woboola pakati chubu lalikulu.
Gulu lamankhwala apamwamba
Mapaipi apakati amagawidwa m'mapaipi otentha, mipope yamagetsi yama electro galvanized square, mapaipi apakati opaka mafuta ndi mipope yamapaipi osakaniza molingana ndi chithandizo chapamwamba.
Gwiritsani ntchito magulu
Machubu a square amagawidwa malinga ndi cholinga: machubu apakati okongoletsa, machubu akulu akulu azida zamakina, machubu apamtunda amakampani opanga makina, machubu akulu akulu amakampani opanga mankhwala, machubu akulu akulu achitsulo, machubu apamtunda opangira zombo, machubu apamtunda agalimoto, machubu akulu zitsulo zitsulo ndi mizati, ndi masikweya machubu zolinga zapadera.
Gulu makulidwe a khoma
Machubu amakona anayi amagawidwa molingana ndi makulidwe a khoma: machubu owonjezera okhala ndi mipanda amakona anayi, machubu amipanda amakona anayi ndi machubu opyapyala okhala ndi mipanda yamakona anayi.
