摘要：This invention relates to a method of heat treating articles which utilizes afluidized bed comprising a container containing a mass of refractory particles and havinga porous base, a layer of such particles adjacent to the porous base being formed ofheavier particles than the remainder of said refractory particles. According to theinvention, a non- stoichiometric fluidizing and treatment medium is supplied to theunderside of the porous base and flows therethrough into the mass of refractoryparticles at such a velocity as to leave the heavier particles unfluidized while fluidizing theremainder of the particles. A gaseous medium is also introduced into the container at aposition above and spaced from the porous base to together with the non-stoichiometric fluidizing and treatment medium, a combustible mixture which is ignited toheat the mass of refractory particles to a temperature at which the non-stoichiometricfluidizing and treatment medium will carry out the desired heat treatment.
