ʻO ke pihi ʻo Tungsten carbide kahi mea hana wili pōhaku i hoʻomohala ʻia me ka hoʻomohala ʻana i nā hana pōhaku hydraulic. Loaʻa iā ia nā pōmaikaʻi o ka hana hana kiʻekiʻe, ka wikiwiki o ka hoʻoheheʻe ʻana, ka mālama ʻana i ka manawa kōkua, a me nā mea ʻē aʻe, a kūpono ia no ka ʻeli wikiwiki ʻana i nā drill pōhaku kiʻekiʻe. Ke hoʻoheheʻe ʻia ka pōhaku brittle, hoʻohana ʻia kahi drill pōhaku hydraulic kiʻekiʻe, a ʻo kāna hiʻohiʻona nui ʻo ia ka wikiwiki a paʻa ka wikiwiki o ka wili ʻana, a lōʻihi ka pōʻai hou o ka drill bit.

Mai ka 1970s, ʻo ka noiʻi nui a me ka hoʻomohala ʻana me nā pihi pahu pahu carbide ma ke ʻano he huahana nui, a ʻo ke kūʻai aku ʻana i nā ʻāpana pila-niho pōleʻa like ʻole he 60% a 70% o ka huina o nā puka drill bits. I ka makahiki 1968, ua hoʻomohala ʻo Sandvik i kahi pūʻulu o nā ʻāpana pihi pihi nui, waena a me ke anawaena no ka wili pōhaku percussive, a ua manaʻo ʻia ʻo ia he "mea hana hoʻoheheʻe kūpono no nā hoʻoheheʻe pōhaku hydraulic". I kēia mau makahiki i hala iho nei, ma ka mākeke o nā mea hana wili pōhaku, ʻoi aku ka nui o ka nui o nā pihi pihi.

Mai ka makahiki 1980 mai, ua hoʻomaka ʻo Kina e hoʻopili koʻikoʻi i ka noiʻi a me ka hoʻomohala ʻana i nā bit drill bit, a ke piʻi nei ka nui o nā mea hana e hana ana i nā bit drill bit. Mai ka makahiki 1990 mai, ua ulu nui ka nui a me ka maikaʻi o nā pahu drill bits o Kina, a ua hoʻonui ʻia ka nui o ka lawe ʻana aku i kēlā me kēia makahiki. E like me Lianhuashan, Chengtan, Changsha Mining Institute, Changjiang, Shaodong a me nā mea hana nui ʻē aʻe he nui, kiʻekiʻe kiʻekiʻe. Ma waena o lākou, ʻo nā pihi drill bit i hana ʻia e Lianhuashan e noho nui i nā mea hana drill export.

ʻO ka carbide cemented kiʻekiʻe, nā mea hana kiʻekiʻe kiʻekiʻe, ka ʻenehana hana kūpono a me ka ʻenehana mālama wela ka mea e pono ai e hōʻoia i ka maikaʻi o ka huahana i ke kaʻina hana o nā pihi drill bits. No ka mea, ʻo ke kila i hoʻohana ʻia no ka hana ʻana i nā pihi pihi kila i hana nui ʻia i ke kila chromium-nickel-molybdenum a i ʻole silicon-manganese-chromium-nickel-molybdenum steel, ʻoi aku ka kiʻekiʻe o ke kila kila. No ka carbide cemented, hiki iā ʻoe ke koho i ka carbide cemented kiʻekiʻe o ZZBETTER.

Loaʻa iā ZZBETTER kahi kī piha o nā pihi carbide cemented, a hiki ke hana ʻia a hana ʻia nā ʻano nui o nā pihi mining carbide cemented.

Nā pihi tungsten carbide ZZBETTER:

Nā pōmaikaʻi o nā pihi tungsten carbide

1.Having kū hoʻokahi hana hana

2.High paʻakikī a me ka maikaʻi ʻaʻahu kūʻē

3. Hoʻohana nui ʻia i ka eli ʻana i nā pōhaku like ʻole a me ka ʻaila ʻaila.

4.Suitable no ka uhai ikaika loa granite, limestone a me ka ilihune hao oka, etc.

Nā noi o nā pihi tungsten carbide

1.Oil drilling and shoveling, nā mīkini palau hau a me nā mea hana ʻē aʻe.

2. Hoʻohana ʻia no nā mea hana ʻeli lanahu, nā mea hana mīkini mining a me nā mea hana mālama alanui.

3. Hoʻohana ʻia i ka ʻeli ʻana, mining, tunneling, a me ke kūkulu kīwila.

4.DTH Drill bit, thread drill bit a me nā mea drill ʻē aʻe.
