Tasirin Niƙa Wet don Cakudar Carbide Siminti

Dalilin rigar milling shine a niƙa tungsten carbide foda zuwa girman barbashi da ake so, don cimma isasshiyar haɗaɗɗiya iri ɗaya tare da foda cobalt a cikin wani ƙayyadadden ƙayyadaddun ƙayyadaddun abubuwa, da samun kyawawan kaddarorin latsawa. Wannan tsarin niƙa mai jika ya fi ɗaukar ƙwallon tungsten carbide da hanyar mirgina barasa.

Menene tasirin niƙa rigar don gaurayawan carbide tungsten?

1. Hadawa

Akwai abubuwa daban-daban a cikin cakuduwar, kuma yawa da girman barbashi na kowane bangare shima ya bambanta. Don samun samfuran siminti masu inganci, injin niƙa na iya tabbatar da cewa dole ne a rarraba abubuwan da ke cikin cakuda daidai gwargwado.

2. Rushewa

Ƙayyadaddun ƙayyadaddun ƙayyadaddun abubuwan da aka yi amfani da su a cikin cakuda sun bambanta, musamman WC wanda ke da tsarin agglomerate. Bugu da ƙari, saboda ainihin buƙatun aiki da samarwa, WC na maki daban-daban da nau'ikan ƙwayoyin cuta galibi ana gauraye su. Wadannan al'amura guda biyu suna haifar da babban bambanci a cikin nau'in nau'in nau'in kayan aiki, wanda ba shi da amfani ga samar da kayan aiki masu kyau. Rigar nika na iya taka rawa na murkushe kayan abu da kuma girman nau'in homogenization.

3. Oxygenation

Hatsari da gogayya tsakanin cakuduwar, abin nadi, da ƙwallayen niƙa sun fi saurin kamuwa da iskar oxygen. Bugu da ƙari, ruwan da ke cikin barasa na milling yana inganta tasirin oxygenation. Akwai hanyoyi guda biyu don hana oxygenation: ɗaya yana sanyaya, gabaɗaya ta ƙara jaket mai sanyaya ruwa a waje da ganga na ƙwallon ƙwallon don kula da zafin jiki yayin aikin injin ƙwallon; ɗayan kuma shine zaɓin tsarin samarwa da ya dace, kamar wakilin noman ƙwayoyin cuta da albarkatun ɗanyen ƙwallon ƙafa tare saboda abubuwan da ke samar da kwayoyin halitta suna yin fim ɗin kariya a saman albarkatun ƙasa, wanda ke da tasirin ware iskar oxygen.

4. Kunnawa

A cikin aikin milling na ball, saboda karo da gogayya, kristal lattice na foda yana da sauƙin jujjuya shi kuma yana daɗaɗawa, kuma ƙarfin ciki yana ƙaruwa. Wannan kunnawa yana da amfani ga sintering shrinkage da densification, amma kuma yana da sauƙi don haifar da "fashe", sa'an nan kuma girma maras kyau yayin sintering.

Domin rage tasirin kunnawa, rigar niƙa kada ta yi tsayi da yawa. Kuma zaɓi lokacin jiƙan da ya dace daidai da girman barbashi na cakuda.

Idan kuna sha'awar samfuran carbide tungsten kuma kuna son ƙarin bayani da cikakkun bayanai, zaku iya tuntuɓar mu ta waya ko wasiƙa a hagu, ko Aika wasiƙun Amurka a kasan shafin.
