TY - JOUR AU - Nikolaev, A. AB - V. G. Borisov and A. R. Nikolaev UDC 666.763.42.041 The service life of tarred-dolomite converter refractories is increased by the use of dense dolomite clinker with low impurity concentrations in their production [1]. This clinker can be obtained froradolomites from various deposits by developing high temperatures in the firing zone of the rotary kilns, but such tem- peratures are difficult to achieve and affect adversely the resistance of the kiln lining. Only in certain cases is it possible to obtain high-density clinker with ordinary calcination techniques [2]. It is possible to obtain high-density clinker by adding substances to the dolomite which reduce its sintering temperature but these additions simultaneously impair the service properties of the clinker. There also existmethods of preparing raw materials so as to allow a denser product to be obtained under the same conditions of firing. Thus a method has been proposed for obtaining dolomite clinker with an apparent density of 3.1-3.2 g/cm ~ by firing at a temperature of not more than 1700~ and soaking up to 30 min [3]. Natural dolomite containing very small impurities is fired at 1200-1400~ converting it into "caustic" having a loss upon ignition of not more than 10%.
