Chiyambi cha makhalidwe a chrome refractory njerwa

Njerwa zomangira chromium zimakhala ndi zinthu zambiri za Cr2O3 (zoposa 30%), pomwe njerwa zomangira zokhala ndi MgO zochepa (10-30%) ndi njerwa zomangira chromium.

Khalidwe lake lalikulu ndilakuti ndi ndale refractory zakuthupi. Chifukwa Cr2O3 ndi osayidi osalowerera ndale, imakana bwino ku slag yamchere ndi acid slag. Njerwa za Chrome nthawi zina zimagwiritsidwa ntchito pomanga pamphambano wa njerwa za asidi refractory ndi njerwa zamchere zotchinga kuti apewe kuchitapo kanthu pakati pa njerwa za asidi refractory ndi njerwa za alkaline refractory pa kutentha kwambiri.
