Реферат | This work has the following purposes: increasing of resistance of linings of horizontal copper-nickel converters and rotary furnaces; study of reasons of low resistance of tuyere zone of converters and reaction zone of rotary furnaces; development of methods of soaking of standard refractories by various joints; creation of efficient refractory masses, adhesives, guncrete bodies and laying designs. There were developed the technologies of soaking of refractories by phosphate binders and mattes. Testing and implementation of the foregoing activities allowed to increase the resistance of lining of converters and rotary furnaces by 1.5–2 times at non-ferrous metallurgy enterprises. It was also possible to realize the reduction of number of maintenances and losses of non-ferrous metals. Authors have developed a new method for determination of slag resistance of refractory masses and laying solutions on the basis of various magnesia powders of both sintered, fused and various ligaments. Solution of fused periclase-chromite and orthophosphoric binder is the most resistant to copper and nickel converter slag. There was developed a range of methods of improvement of Russian refractory products by soaking with aluminophosphate joint. There was made a proposition to use a heat transfer mass on the basis of chromite-periclase and cast iron powder with liquid glass. Synthesized materials with high physical and mechanical properties were created on the basis of self-spreading hightemperature synthesis. Testing and implementation of the foregoing activities made it possible to do the following operations: increasing of resistance of lining of converters and rotary furnaces by 1.5–2 times at non-ferrous metallurgy enterprises; reduction of number of maintenances and losses of non-ferrous metals. Thus, it is appropriate to create a number of sites for production of the considered refractory materials and for creation of a range of guncrete installations for carrying out of «hot» maintenances. |
