Kaalay oo wax ka baro HSS
Steel xawaare sare leh Waxaa sidoo kale loo yaqaannaa birta cad.
Steel xawaare sare leh waa bir bir ah oo leh aalad cakiran oo ay ku jiraan walxaha dhismaha ee ay ka kooban tahay walxaha ka mid ah waxyaabaha loo yaqaan 'Carbide' sida Tungsten, Molybdem, Chromium, Valatt. Wadarta tirada walxaha ka kooban waxay gaarayaan 10 ilaa 25%. Waxay ilaalin kartaa adkaanta sare ee ka hooseysa kuleylka sare (qiyaastii 500 ℃) Goynta xawaaraha sare, HRC waxay ka sarreyn kartaa 60. Tani waa dabeecadda ugu muhiimsan ee HSS - casaan casaan ah. Iyo birta kaarboon-ka-goynta ah oo hoos udhaca iyo kuleylka heerkulka hoose, heerkulka qolka, in kasta oo ay jirto si heer sare ah, laakiin si buuxda ayaa heerkulku u daadanayaa in la gooyo aaladda birta, taas oo xaddidaysa qalabka goynta goynta goynta goynta goynta goynta alwaaxda. Iyo bir xawaare sare leh awgood adag oo casaan ah oo wanaagsan, si loogu sameeyo khaladaadka dilaaga ah ee birta kaarboon-ka ah.
Birta xawaaraha sare ayaa inta badan loo isticmaalaa in lagu soo saaro aalado goyn kara oo jilicsan oo jilicsan oo u adkaysan kara.
Kaalay oo baro wax ku saabsan Tungsten bir
Tungsten Star (Carbide) wuxuu leeyahay taxane guryo aad u wanaagsan sida adkaanta sare, iska caabbinta, iska caabinta, iska caabbinta, iska caabbinta, iyo is-caabbinta, iyo waliba waxay leeyihiin si heerkul ah oo ah 500 ℃.
Tungsten Birta, oo qaybaha ugu weyn ay yihiin Tungsten Carbide iyo Cobalt, ayaa ah 99% dhammaan qaybaha kale, sidoo kale waxaa loo arkaa inay yihiin hilib loo yaqaan 'Tungsten bir', waxaana loo arkaa inay tahay ilkaha warshadaha casriga ah.
Tungsten Birta waa shey isku dhafan oo ku saleysan ugu yaraan hal bir bir ah. Tungsten Carbide, Cobalt Carbide, Niobium Carbide, Niobium Carbide, titanium Carbide, Tantalum Carbide, iyo Tantalum Carbide waa qaybo caadi ah oo ah tungsten bir bir ah. Cabbirka hadhuudhka ee qaybta 'karbide' (ama wajiga) ayaa caadi ahaan ku jira baaxadda 0.2-10 micraan micron, iyo hadhuudhka carbiska ah ayaa isku xidhnaa iyadoo la adeegsanayo bir bir ah. Birta isku xidhka ayaa guud ahaan waa birta birta birta ah, caadi ahaan cobalt iyo nickel. Markaa waxaa jira Tungsten-Cobalt alloys, Tungsten-Nickel Alles iyo Tungsten-Titanium-tittt alls.
Tungsten demster oo qaabeysan ayaa ah in foornada lagu riixo si ay ugu kululeeyaan heerkul gaar ah (waqti cayiman) oo ku qabooji si aad u hesho sheyga birta ee Tungsten ee guryaha loo baahan yahay.
①Tungsten iyo Cebatten Chanted Carbide
Qeybta ugu weyn waa Tungsten Carbide (WC) iyo Cint Chanttt (Co). Darajada waxay ka kooban tahay "YG" ("adag, cobaltt" ee Hanyan Pinyin) iyo boqolleyda celceliska cobalt cobalt. Tusaale ahaan, YG8, oo macnaheedu yahay celceliska WCO = 8% halka inta soo hartayna waa Tungsten Carbide Carbide.
②Tungsten, tatnium iyo coother conbide
Waxyaabaha ugu waaweyn waa Tungsten Carbide, Ttanium Carbide (TIC) iyo Cobalt. Darajada waxay ka kooban tahay "YT" ("adag, Titanium" ee Hanyan Pinyin) iyo celceliska nus-darada ee Titanium Carbide. Tusaale ahaan, YT15, waxaa loola jeedaa celceliska TIC = 15%, inta soo hartay waa Tungsten Carbide iyo Chrottens-ka Cobaten ee TITALTEN COBTIde Carbide.
③Tungsteren-titnium-tantaum (niobium) carbide
Waxyaabaha ugu waaweyn waa Tungsten Carbide, titanium Carbide, Tuntalus Carbide (ama niobium carbide) iyo cobalt. Carbide noocan ah waxaa sidoo kale loo yaqaannaa ujeedada guud ee loo yaqaan 'carbide guud' ama 'Universal Carbide'. Darajada ayaa ka kooban "YW" ("adag" iyo "milyan" oo ku taal Hanyan Pinyin) oo lagu daray lambar isku mid ah, sida YW1.
Tungsten Steel ayaa leh taxane guryo aad u wanaagsan sida adkaanta sare, caabbinta ka fiican, adkeyn, iska caabbinta kuleylka, iwm. Carbide-ka sibidhka ayaa si weyn loogu isticmaalaa sidii qalab ahaan, sida aaladaha iftiinka, aaladaha dhajinta, aaladaha, aaladaha caajiska ah, iwm.
