Channel Steel - enye yeyona ixhaphakileyo metal iintlobo

Nayiphi zokwakha (mveliso okanye civil) ziphelele ngaphandle kokuba ukusebenzisa inani elikhulu kwimpahla yentsimbi ezahlukeneyo (iimpahla zesinyithi) oko kunokusetyenziswa njengezixhobo eqwalasele, kwaye njengenxalenye njengelungu inkxaso noshowo. Kwiimeko ezininzi sincanyathiselwe zenziwe iintlobo ezahlukeneyo ngentsimbi (carbon kukhethwa ephantsi), kwaye ethandwa kakhulu phakathi kwazo iimveliso ngesinyithi, ingakumbi iiprofayili zokwakha. Ngokwakha iinkangeleko ziquka iimveliso ezifana imiqadi, brand, I-imiqadi, imijelo, i-engile, njl

Eli nqaku igxininisa imiphantsi, ezisetyenziswa kumacandelo ahlukeneyo zombini yokwakha mveliso kunye yoluntu.

Ingcamango of U-amacandelo

amajelo Beam (itshaneli intsimbi) ibizwa umqadi ube mnye apho has a icandelo emise-U emnqamlezweni; Loo candelo kuthiwa 'ibhokisi-like ". Kwiimeko ezininzi namajelo isetyenziswe njengento inikeza extra umgangatho ezinzileyo kunye ngqongqo belenza. Kananjalo ikwanika ukuxhathisa elihle lokuba imithwalo yezihlunu kunye ukugoba.

Yintoni eyenza?

Ngokuphathelele izinto yokuvelisa, wayedla ngokusebenzisa iintlobo ezahlukeneyo ngesinyithi (steel noshowo kunye ongeziweyo alloying, onekhaboni ephantsi kunye omkhulu), ngokuxhomekeke kwiimfuno eso sakhiwo. Ngenxa yoko, eneneni, lo gama - i "ijelo kwensimbi." Kwezinye iimeko, ezifana ekwakheni emotweni, liye emivalweni, kukho iimfuno ezikhethekileyo; zimele ukuba iipropati anti-entsimbini. Ukuze ezi njongo, wenza imijelo ezikhethekileyo insimbi, iindleko iza kuba ngaphezulu, kodwa iimpawu thermo-emzimbeni ezifanayo, ukuba eqinile kakhulu kwiimpembelelo bangaphandle, xa kuthelekiswa ne-bar channel eshushu.

ngezigaba

Channel steel nemveliso metal liqengqiwe, ukuba zihlelwe ngolu hlobo lulandelayo:

1. Ngokuxhomekeke inkqubo yokuvelisa:

• amajelo steel Hot-liqengqiwe (iveliswayo ehlelayo eshushu);
• okhethekileyo;
• alinganayo egobile (iveliswayo bagobe abandayo umatshini okhethekileyo bokwakha);
• ukungalingani egobile (iveliswayo ubuchwepheshe obufanayo njengoko ifom elidlulileyo).

Phela, kufanele kuqatshelwe ukuba intsimbi channel ezishushu liqengqiwe, ibheke ngokwangaphandle ezahlukeneyo: yokugqibela yi ukhetho xa ubuso isondezwa, oko kukuthi, imveliso ayinazo iikona ezibukhali, ngelixa eshushu-wethala kusoloko kukho iimbombo (bona ifoto ngezantsi.).

2. Ngokuxhomekeke imilo nobukhulu:

• Thina - olu hlobo uye elintlangothi angaphakathi ezishelifini kunye icala elithile;
• P - iishelfu imveliso kunye ubuso parallel;
• E - imodeli eyongayo elintlangothi engumzekelo kweeshelfu;
• L - iimodeli series ukukhanya ngobuso parallel;
• C - udibaniso series okhethekileyo.

3. Ngokusekelwe ukuchaneka yokusebenza ezityikitywe, imijelo bangaba:

• A - yeklasi (class ngqo phezulu);
• B - class (ngokuchanekileyo ephakamileyo);
• B - yeklasi (class of omnye-ngqo).
