Kusiyana pakati pa Tungsten Carbide ndi HSS Cutting Tools

Kuphatikiza pa zida za tungsten carbide, zida zodulira zimatha kupangidwanso ndi zitsulo zothamanga kwambiri. Komabe, chifukwa cha mitundu yosiyanasiyana ya mankhwala ndi njira zopangira tungsten carbide ndi zitsulo zothamanga kwambiri, ubwino wa zida zodulira zomwe zakonzedwa ndizosiyana.

1. Mankhwala katundu

Chitsulo chothamanga kwambiri, chomwe chimatchedwanso kuti chitsulo chothamanga kwambiri kapena chitsulo chakutsogolo, chimatchedwanso HSS, zigawo zikuluzikulu za mankhwala ndi carbon, silicon, manganese, phosphorous, sulfure, chromium, molybdenum, faifi tambala, ndi tungsten. Ubwino wowonjezera tungsten ndi chromium kutsogolo kwachitsulo ndikukulitsa kukana kofewa kwa chinthucho chikatenthedwa, potero kumawonjezera kuthamanga kwake.

Tungsten carbide, yomwe imadziwikanso kuti cemented carbide, ndi alloy material yozikidwa pazitsulo zosakanizika zazitsulo ndi zitsulo ngati zomangira. Magulu olimba omwe amapezeka ndi tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, tantalum carbide, ndi zina zambiri, ndipo zomangira wamba ndi cobalt, faifi tambala, chitsulo, titaniyamu, etc.

2. Zinthu zakuthupi

Mphamvu yosunthika yazitsulo zothamanga kwambiri ndi 3.0-3.4 GPa, kulimba kwake ndi 0.18-0.32 MJ/m2, ndipo kuuma kwake ndi 62-65 HRC (kutentha kumakwera mpaka 600 ° C kuti kuuma kudzakhala 48.5 HRC). Zitha kuwoneka kuti chitsulo chothamanga kwambiri chimakhala ndi mphamvu zabwino, kukana kuvala bwino, kukana kutentha kwapakatikati, komanso kutsika kwa thermoplasticity. Zoonadi, zizindikiro zenizeni za zitsulo zothamanga kwambiri zimagwirizana kwambiri ndi mankhwala ake komanso chiŵerengero cha zinthu zopangira.

Mphamvu yopondereza ya tungsten carbide yomwe imagwiritsidwa ntchito kwambiri ndi 6000 MPa ndipo kuuma kwake ndi 69 ~ 81 HRC. Kutentha kukakwera mpaka 900 ~ 1000 ℃, kuumako kumatha kusungidwa pafupifupi 60 HRC. Kuphatikiza apo, ili ndi mphamvu zabwino, kulimba, kukana kuvala, kukana kutentha, komanso kukana dzimbiri. Komabe, zizindikiro zenizeni za carbide yopangidwa ndi simenti ndizogwirizana kwambiri ndi kapangidwe kake ka mankhwala ndi chiŵerengero cha zinthu zopangira.

3. Njira yopangira

Njira yopangira chitsulo chothamanga kwambiri nthawi zambiri imakhala: kusungunula ng'anjo pafupipafupi, kuyengetsa kunja kwa ng'anjo, kusungunula vacuum, kusungunula kwa electro slag, makina othamanga, nyundo yopumira, kubisa makina olondola, kugubuduza kotentha muzinthu, chinthu chamba, ndi kujambula. mu mankhwala.

Kapangidwe ka tungsten carbide nthawi zambiri ndi: kusakaniza, mphero yonyowa, kuyanika, kukanikiza, ndi sintering.

4. Ntchito

Chitsulo chothamanga kwambiri chimagwiritsidwa ntchito kwambiri popanga zida zodulira (monga zobowolera, matepi, ndi masamba a macheka) ndi zida zolondola (monga ma hobs, zojambulira zida, ndi ma broaches).

Kupatula zida zodulira zomwe tungsten carbide imagwiritsidwanso ntchito popanga migodi, kuyeza, kuumba, kusavala, kutentha kwambiri, ndi zina.

Makamaka pansi pazikhalidwe zomwezo, kuthamanga kwa zida za tungsten carbide ndi 4 mpaka 7 kuposa chitsulo chothamanga kwambiri, ndipo moyo ndi 5 mpaka 80 nthawi zambiri.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZANI MAIME pansi pa tsamba.
