摘要
the present invention refers to a process of manufacture of refractory products dolomitice and magnezio - dolomitice liate ceramic.characterized by a high stability and a hydration speed and 1 three times less than similar products related with tar and termooxidate.the raw materials used are refractory material with iron free (10 70%) and mgo content (40 90%), obtained from mixture of treading brucitice, dolomite with and without mgo, sintered in 1850..1900 degree c.the glue used on the basis of paraffin, wax and harnessing waste polythene, mineral oil and vaseline semifabricatului stability of special temporary before combustionand after eliminate combustion without residue, coking, giving the final product texture with little direct connection, porosity, high density, high compresiuni resistant.
