Makhalidwe ndi Ntchito za Cemented Carbide

Makhalidwe a tungsten carbide

Tungsten carbide imakhala ndi kuuma kwakukulu komanso kukana kuvala. Kuthamanga kwa zida za carbide ndi 4 mpaka 7 kuposa chitsulo chothamanga kwambiri komanso nthawi 5 mpaka 80 moyo wapamwamba wa utumiki. Zogulitsa za Carbide zimatha kudula zida zolimba pafupifupi 50HRC. Zolembazi zipereka chidziwitso chofunikira chokhudza simenti ya carbide.

Zakuthupi za tungsten carbide

Simenti carbide makamaka ndi yaying'ono-kakulidwe ufa wa carbides (WC, TiC) high-kuuma refractory zitsulo. Zigawo zikuluzikulu ndi ufa metallurgical mankhwala sintered mu ng'anjo zingalowe kapena wa hydrogen kuchepetsa ng'anjo ndi cobalt (Co), faifi tambala (Ni), ndi molybdenum (Mo) monga binder.

Matrix a carbide opangidwa ndi simenti amapangidwa ndi magawo awiri: gawo limodzi ndi gawo lolimba, ndipo gawo lina ndi chitsulo chomangira.

Gawo lowumitsidwa ndi carbide, monga tungsten carbide, titanium carbide, ndi tantalum carbide. Kuuma kwake ndikokwera kwambiri. Malo ake osungunuka ali pamwamba pa 2000 ° C, ndipo ena amatha kupitirira 4000 ° C. Kukhalapo kwa gawo lowumitsa kumatsimikizira kuuma kwambiri komanso kulimba kwa carbide.

Tungsten carbide WC kukula kwa tirigu zofunika carbide simenti ntchito zosiyanasiyana tirigu kukula WC malinga ndi ntchito zosiyanasiyana.

Nkhaniyi makamaka ikuwonetsa ntchito zitatu za simenti ya carbide:

1. Tungsten carbide yopangira zida zodulira carbide

Zida zodulira Carbide zimagwiritsidwa ntchito kwambiri podula zitsulo ndi kukonza. Makina opangira makina abwino monga mabala odulira phazi ndi mipeni ya V-CUT amagwiritsa ntchito WC yabwino kwambiri, yocheperako, komanso yosalala bwino. Zosakaniza zopangira zitsulo zimagwiritsa ntchito WC watiriji. Ma aloyi odulira mphamvu yokoka ndi zida zodulira zolemetsa amagwiritsa ntchito sing'anga ndi coarse Granular WC ngati zopangira.

2. Simenti ya carbide yopangira zida zamigodi ya carbide

Mwalawu uli ndi kuuma kwakukulu komanso kukhudzidwa kwakukulu. Coarse WC imatengedwa, ndipo mphamvu yamwala ndi yaying'ono yokhala ndi katundu wochepa. WC yapakatikati imagwiritsidwa ntchito ngati zopangira.

3. Aloyi yolimba yopangira zida zolimbana ndi carbide

Pogogomezera kukana kwake kuvala, kukana kukanikiza, ndi kutha kwa pamwamba, WC yokhala ndi makulidwe osiyanasiyana imagwiritsidwa ntchito ngati zopangira, ndipo zapakati komanso zobiriwira za WC zimagwiritsidwa ntchito ngati zida zazikulu.

4. Chitsulo cholimba chopangira tungsten carbide Imafa

Ma carbide amafa amakhala ndi moyo wautali nthawi makumi angapo kuposa nkhungu zachitsulo. Chikombole cha carbide chimakhala ndi kuuma kwakukulu, mphamvu zambiri, kukana kwa dzimbiri, kukana kutentha kwambiri, ndi kagawo kakang'ono kakukulitsa, komwe kamene kamapangidwa ndi tungsten cobalt.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena KUTITUMIZIRA MAIL pansi pa tsambali.
