截齒等離子堆焊層的工況條件比較復(fù)雜，截齒在切割煤巖過(guò)程中除了承受周期性壓應(yīng)力、切應(yīng)力和沖擊載荷作用外，還要承受長(zhǎng)時(shí)間磨粒磨擦、沖擊產(chǎn)生的溫升作用以及腐蝕介質(zhì)的腐蝕作用。因此，截齒堆焊耐磨層的作業(yè)環(huán)境較為復(fù)雜、惡劣。 </p> <p> 截齒等離子堆焊層的性能要求比較苛刻，首先自身要耐磨，也就是說(shuō)在采煤過(guò)程中，截齒堆焊層與煤層間會(huì)發(fā)生持續(xù)磨擦運(yùn)動(dòng)，截齒堆焊層必須經(jīng)受住煤層的長(zhǎng)時(shí)間磨損。 </p> <p> 在這種情況下，堆焊層的硬度、耐磨性越高越好；其次，必須考慮截齒在切割煤巖過(guò)程中不可避免的沖擊載荷作用，如果堆焊層的硬度太高，金屬韌性較差，堆焊層金屬容易發(fā)生崩裂或斷裂。因此，堆焊層的硬度不一定是越高越好，而是應(yīng)當(dāng)綜合考慮，使其具有良好的綜合抗磨性能。 </p> <p> 同時(shí)需要注意，煤巖材料特性對(duì)堆焊耐磨層的影響。煤質(zhì)的軟硬以及夾矸石的多少，對(duì)截齒堆焊層磨損影響非常明顯。煤質(zhì)較軟、夾矸石較少的煤巖，截齒切割阻力較小，采煤機(jī)牽引阻力也較小，截齒的磨損率較??；反之，截齒的磨損率較大。 </p> <p> <br /> 溫州閥座堆焊技術(shù)</p><p
