Paʻa kiʻekiʻe ʻo Tungsten Carbide Roller Ring for High Speed ​​Rolling of Alloy Steel Bars

Ua hānau ʻia nā apo carbide wili me ka hoʻomohala ʻana i ka ʻoihana hana metala ma hope o ka hiki ʻana mai o ka ʻenehana pauka metallurgy ma 1909. Mai ka hoʻokomo ʻia ʻana o ka cemented carbide uea kaha kiʻi make ma Germany i ka makahiki 1918, ua hoʻoulu ʻia ka noiʻi ʻana i ka carbide cemented ma nā ʻāina like ʻole, a me nā ʻōwili. no na mea like ole, ua puka mai kekahi mahope o kekahi.Eia naʻe, ua hele mai ka nui-nui o ka cemented carbide rollers ma hope o 1960. I ka makahiki 1964, i ka hanau ana o ka mua kiʻekiʻe-māmā nui wili-free uea koʻokoʻo rolling wili o Morgen Company hoonui i ka pau ana o ka uwea kookoo e 4 manawa.Ma muli o ka hana ʻana o ka mīkini wili hoʻopau i ka wikiwiki kiʻekiʻe a me ke koʻikoʻi kiʻekiʻe, ʻoi aku ka maikaʻi o ka pale ʻana o nā wili hao a me nā mea kila kila, pōkole ke ola o ka ʻōwili, a ʻo ka hoʻoponopono ʻana a me ka hoʻouka ʻana a me ka wehe ʻana o nā ʻōwili e pinepine pinepine ʻia. ka pono o ka wili wili a ʻaʻole kūpono hou no ka hoʻopau ʻana i ka hana ʻōwili.pono, no laila ua pani ʻia e nā huila carbide hui.Aia ma mua o 200 mau wili aʻa ma ka honua, e ʻai ana i nā haneli haneli o ka carbide cemented rolling i kēlā me kēia makahiki.
