Indlela ukukhetha kwesokudla usayizi Sills

Ukuma sici steel futhi amandla awo izici niyenzé ukusetshenziswa ngezihloko ezihlukene emikhakheni eyehlukene yomnotho. Kuye isicelo, khetha Tinhlobo nosayizi imigoqo siteshi. Zisetshenziswa zokuhlala kanye nokwakhiwa zezimboni, imishini, ujantshi imoto, ngesikhathi elungisa ahlukahlukene okwenza Shelving nokuqiniswa phansi, futhi ongaphandle kudivayisi ukukhangisa ramps.

Isiteshi ngenkuthalo esetshenziswa njengoba isici ezihlelekile womshini Cranes, amabhuloho, high voltage pylons, uwoyela yokumba, iyiphi nohlaka wokwakha ukuvala zokuxhumana. Nomaphi lapho udlala amandla indima ubuhlungu impahla obalulekile ngesikhathi isisindo iphansana.

izinhlobo Sills

Indaba eziyisisekelo womshini mikhiqizo - steel (carbon kwesakhiwo, ingxubevange ongaphakeme, iphuma ashisayo nabandayo iphuma). Hlukanisa esishisayo (ngokunemba abavamile futhi anda ugingqe) kanye isiteshi insaliwe.

Hot iphuma steel ejwayelekile emashalofini okufanayo, kodwa zingase zimiswe nge eyehlelayo (hhayi ngaphezulu kuka-10%). Ubukhulu Sills inhloso jikelele noma injongo ekhethekile (ngokukhethekile, ngoba yezimoto) kuhluke ububanzi nobude emashalofini (Ubukhulu zinikwa CCITT 8240-89, futhi 19425-74). GOST Hlukanisa ukhona amaphrofayli yokwakha imoto (GOST 5267.1-90).

umkhiqizo Bent kungukubonakala ohlukaniswa le oyindilinga kwangaphakathi ekhoneni emashalofini futhi ilingana futhi engalingani. It has a usayizi isiteshi (GOST 8278-75) ubude namamitha angu-12, kodwa ngesicelo futhi ukukhiqiza amaphrofayli isikhathi eside.

Ubukhulu Sills

Uma ukhetha iphrofayli uholwe imingcele yayo eziyisisekelo enquma ukuphakama, ububanzi kanye flange ukujiya, udonga ukujiya, engaba sangaphakathi ugobile noma ukuqoqa emashalofini.

Kukhona izinhlobonhlobo eziningi, osayizi kanye nezici kulawulwa amazinga. Ngakho-ke, ikhwalithi yomkhiqizo kulula ukunquma ngokuqhathanisa Ubukhulu langempela U-izigaba licaciswe ku GOST.

ubuqili kophawu

Lapho wokugubha ubukhulu iphrofayela ngokuvamile kukhonjisiwe amasentimitha futhi izinhlamvu uqoke ipharamitha ngabanye. Ngokwesibonelo, isiteshi 8P, izilinganiso okuyizinto ejwayelekile, uthi ukuphakama kwalo - 8 amasentimitha, futhi emashalofini ngokulinganisa. By the way, imikhiqizo usayizi standard advantageously esetshenziswa reinforcer izakhiwo, njengoba bebizwa ashiselwe ndawonye ngaphandle kwezinkinga, futhi ekhiqizwa kusuka olinganiselayo nokuzola carbon steel.

Ukuze nokwehlisa ukwakhiwa isiteshi metal futhi wasebenzisa 12P, esesikhundleni ephakeme izici amandla. Kodwa umdayisi kuwukwenza iphrofayli ashisayo-16P.

Ngokucacile metal kwesicelo ngokuvamile kuxhomeke ekutheni lo steel grade, esetshenziselwa ukukhiqizwa yayo. Ngokwesibonelo, izinhlelo zokusebenza e ezingxenyeni ezikude zenyakatho, lapho amazinga okushisa aphansi kukhona iziteshi evamile ukusetshenziswa eyenziwe ongaphakeme-carbon steel kwesakhiwo 09G2S. Lokhu kungenxa yokuthi amandla high mechanical grade kunikezwa steel, kalula Welding, ukumelana okushisa aphansi.
