Mitundu ya DTH batani pang'ono ndi mabatani pa izo

Masiku ano, zopangidwa ndi tungsten carbide zimawoneka m'malo osiyanasiyana ogwirira ntchito ngati zida za tungsten carbide kapena tungsten carbide zomangika ku zida zina zazikulu. Bokosi la Down-The-Hole (DTH) nthawi zonse limafuna mabatani apamwamba kwambiri a tungsten carbide omwe amakana kukhudzidwa kwambiri komanso kuvala kwa abrasive. Mabatani a DTH amagwiritsidwa ntchito pobowola DTH kuti apange dzenje lolunjika kapena dzenje lolowera lomwe lili ndi mainchesi akulu. Atha kugwiritsidwanso ntchito pobowola m'miyala yolimba komanso yolimba. M'nkhaniyi, tikambirana zambiri za mabatani a DTH ndi mabatani a tungsten carbide omwe amagwiritsidwa ntchito pa iwo.

Mitundu ya DTH Button Bits

Malinga ndi mawonekedwe osiyanasiyana a mabatani a mabatani, mabatani a DTH amatha kugawidwa m'mitundu itatu ya mabatani. Ndi mabatani a concave, mabatani a convex, ndi mabatani amtundu wathyathyathya.

1. Mabatani a Concave

Mabatani a concave amadziwika ndi mawonekedwe a concave komanso ozungulira pamakona a batani. Mzere wamkati ndi wakunja zonse zimayikidwa ndi mabatani a tungsten carbide. Ndipo mzere wamkati umayikidwa kuti uteteze mzere wakunja kuti usavale kwambiri. Nthawi zambiri, mabatani a concave amatha kuthana ndi mapangidwe ovuta kwambiri.

2. Mabatani a convex

Mosiyana ndi mabatani a concave, mabatani a convex amakhala opindikira ndipo amazungulira kunja kwa mabataniwo. Ndiwoyenera kwambiri pamiyala yofewa kapena yapakati, monga miyala yamchere, shale, kapena miyala yomwe yatha kale. Ndi pakati panja, mabatani a convex adzakhala ndi kulowera kwabwinoko.

3. Mabatani a nkhope yosalala

Mabatani ankhope yathyathyathya alibe chakunja kapena mkati pa batani la tungsten carbide koma amakhala athyathyathya. Amagwiritsidwa ntchito pokumba mapangidwe olimba monga granite, basalt, kapena miyala yamchere yolimba.

Mabatani a Tungsten Carbide

Mabatani a Tungsten carbide pa mabatani a DTH amapangidwa ndi ufa wa WC ndi zomangira zina ngati cobalt. Pambuyo njira zotsatizana monga kusakaniza, mphero, kukanikiza, ndi sintering, mabatani a tungsten carbide amakhala ndi kuuma kwakukulu, kukana, ndi kulimba. Ndi mabatani a tungsten carbide pamenepo, mabatani a DTH ndi amphamvu kwambiri.

ZZBETTER Tungsten Carbide nthawi zonse imayika mawonekedwe apamwamba pa gawo loyamba. Ngati mukufuna mabatani a tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZIRE MAIME pansi pa tsambalo.
