據(jù)了解,超粗晶粒硬質(zhì)合金是一種新型合金,具有極高的熱導(dǎo)率、較高的斷裂韌性與紅硬性、較好的抗熱疲勞與抗熱沖擊等優(yōu)異性能。目前國(guó)內(nèi)先進(jìn)水平的硬質(zhì)合金晶粒度為8微米左右,國(guó)外先進(jìn)水平為10微米左右。
該公司通過(guò)原材料篩選、設(shè)備更新和再優(yōu)化、煅燒、還原、碳化等工藝改進(jìn)而研制的碳化鎢粉,可較好地適應(yīng)超粗晶硬質(zhì)合金對(duì)原料碳化鎢要求,使合金晶粒度超過(guò)10微米,達(dá)到國(guó)內(nèi)領(lǐng)先、江西省內(nèi)首創(chuàng)的水平,形成產(chǎn)業(yè)化生產(chǎn)后,將填補(bǔ)江西作為中國(guó)鎢資源大省無(wú)法批量產(chǎn)出超粗晶硬質(zhì)合金原料碳化鎢粉的空白。
