Za a iya raba ƙwallan ƙarfe na simintin gyare-gyare zuwa sassa uku waɗanda suka haɗa da manyan ƙwallan chromium, ƙwallan chromium matsakaici da ƙananan ƙwallan chromium.

1. Indexididdigar ingancin babban ƙwallon chromium

Abubuwan da ke cikin chromium na babban ball na chromium ya fi ko daidai da 10.0%. Abubuwan da ke cikin carbon tsakanin 1.80% da 3.20%. Dangane da ka’idodin ƙasa, taurin babban ƙwallon chromium dole ne ya zama ƙasa da 58hrc, kuma ƙimar tasirin yakamata ya zama mafi girma ko daidai da 3.0j/cm2. Don cimma wannan taurin, babban ƙwallon chromium dole ne a kashe shi kuma a huce shi a babban zafin jiki. A halin yanzu, akwai hanyoyi guda biyu na kashe manyan ball na chromium a kasar Sin, wadanda suka hada da kashe mai da kashe iska. Idan ƙarfin gwajin babban ƙwallon chromium ya yi ƙasa da 54HRC, yana nufin ba a kashe shi ba.

2. Indexididdigar inganci na ƙwallon chromium matsakaici

Ƙayyadadden abun ciki na chromium na matsakaicin ƙwallon chromium ya fito daga 3.0% zuwa 7.0%, kuma abun cikin carbon yana tsakanin 1.80% da 3.20%. Ƙimar tasirinsa kada ta kasance ƙasa da 2.0j/cm2. Matsayin ƙasa yana buƙatar taurin ƙwallon chrome ya zama mafi girma ko daidai da 47hrc. Domin tabbatar da inganci, matsakaicin ƙwallan chromium yakamata a huce su a babban zafin jiki don kawar da danniya.

Idan saman ƙwallon ƙarfe baƙar fata ne da ja, yana tabbatar da cewa ƙwallon ƙarfe an yi masa maganin zafin zafin jiki. Idan har yanzu saman ƙwallon ƙarfe yana da launi na ƙarfe, zamu iya yin hukunci cewa ƙwallon ƙarfe ba a yi maganin zafin zafin jiki ba.

3. Indexididdigar ingancin ƙananan ƙwallon chromium

Gabaɗaya magana, abun cikin chromium na ƙananan ƙwallon chromium shine 0.5% zuwa 2.5%, kuma abun cikin carbon yana daga 1.80% zuwa 3.20%. Sabili da haka, bisa ga ka’idodin ƙasa, taurin ƙananan ƙwallon chromium yakamata ya zama ƙasa da 45hrc, kuma ƙimar tasirin kada ta kasance ƙasa da 1.5j/cm2. Ƙananan ƙwallan chromium kuma suna buƙatar maganin zafin zafin jiki don tabbatar da inganci. Wannan magani zai iya kawar da damuwa na simintin gyare-gyare. Idan saman ƙwallon ƙarfe yana da duhu ja, yana nuna cewa an yi maganin zafin zafin jiki. Idan har yanzu saman yana da ƙarfe, yana nufin cewa ƙwallon ƙarfe ba a yi zafi ba a babban zafin jiki.

Ana amfani da ƙwallan ƙarfe na siminti daban-daban a masana’antar siminti daban-daban, tsire-tsiren sinadarai, masana’antar wutar lantarki, tsire-tsire yashi quartz, tsire-tsire yashi na silica, da sauransu don manyan ma’adinai.
