Indlela yokuthuthukisa ukufana kwezinga lokushisa kwe isithando somlilo se-tubular?

Eyokuqala: Sebenzisa (ubuchwepheshe obusha) idivayisi evuthayo:

Isishisi esilawula izinga lokushisa esinesivinini esiphezulu sisetshenziselwa ukufaka esikhundleni sokushisa okunesivinini esiphansi sokuqala. I-high-speed burner ngokuyisisekelo iwukushisa okuphelele kukaphethiloli nomoya ovuthayo ekamelweni elivuthayo, futhi igesi ephezulu yokushisa ngemva kokuvutha ijovwe ngesivinini se-100-150m / s, ngaleyo ndlela ithuthukise ukudluliswa kokushisa kwe-convective. Thuthukisa ukuhamba kwegesi esithandweni ukuze ufinyelele umgomo wokushisa okufanayo kwesithando somlilo. Ngaphezu kwalokho, ngokungena emoyeni wesibili, izinga lokushisa legesi elivuthayo eliphumayo liyancishiswa ukuze lisondele ekushiseni kokushisa kwe-workpiece, futhi izinga lokushisa legesi le-flue lingashintshwa ukuze kuthuthukiswe izinga lokushisa futhi longe uphethiloli. Umphumela obalulekile.

Okwesibili: Lawula ingcindezi esithandweni:

Uma ingcindezi esithandweni ingalungile, isibonelo, uma ingcindezi esithandweni ingu-10Pa, isivinini sokudonsa esingu-2.9m/s singakhiqizwa. Ngalesi sikhathi, inani elikhulu lomoya obandayo limuncwa emlonyeni wesithando somlilo nakwezinye izindawo ezingaqinile, okubangela ukuba igesi ye-flue iphume esithandweni. Ukulahlekelwa kwekhalori ekuhambeni kuyanda. Uma ingcindezi esithandweni ilungile, igesi ye-flue ephezulu yokushisa izophuma esithandweni, okuzophinde kubangele ukulahlekelwa ukushisa kwegesi ye-flue.

Okwesithathu: Thuthukisa izinga lokulawula okuzenzakalelayo:

Izinkinga ezibangelwa ukushisa okungafanele zingahlukaniswa zibe:

1. Ukukhubazeka okubangelwa izinguquko esimweni samakhemikhali sengqimba yangaphandle ye-blank ngenxa yethonya le-medium, ithonya le-medium, ithonya le-medium, ukuguqulwa kwesimo samakhemikhali sengqimba yangaphandle ye-blank. okubangelwa i-oxidation, i-decarburization, i-carbonization ne-sulfidation, ukungena kwethusi, njll.

2. Ukukhubazeka okubangelwa izinguquko ezingavamile kusakhiwo senhlangano yangaphakathi, njengokushisa, ukushisa ngokweqile nokuntuleka kokushisa.

3. Ngenxa yokusabalalisa izinga lokushisa elingalingani ngaphakathi kwe-billet, amandla adonsela phansi angaphakathi ngokweqile (njengamandla adonsela phansi, amandla adonsela phansi ezicubu) akhiqizwa, futhi i-billet iyaqhekeka.
