There is a process for creating graphite free non-fired refractory products, which are molded using presses and which includes using a plurality of different binders. The binders comprise a first binder for binding grains of granulation between room temperature and 400&#xb0; C., a second binder binding the grains of granulation between 300 and 900&#xb0; C.; and a third binder binding granulations of the refractory materials that enter into ceramic binding at temperatures above 900&#xb0; C. This process is for producing at least one of magnesia chromite bricks, magnesia spinel and spinel bricks, magnesia zirconia and magnesia zircon bricks, magnesia hercynite and magnesia galaxite bricks, dolomite, dolomite-magnesia, and lime bricks, forsterite and olivine bricks, magnesia forsterite bricks, magnesia pleonast bricks, magnesia bricks. These products are configured to operate as a fire-side, refractory lining of large-volume industrial furnaces operated with an essentially oxidizing atmosphere, for the production of cement, lime, magnesia, and doloma.
