“…The sintering of mullite-corundum ceramic of various compositions has been studied in some detail [1][2][3]. The hotpressing method makes it possible to obtain a dense corundum and mullite ceramic without the impurities which degrade its high-temperature properties [4][5][6][7].

If we compare the wear of the chrome-magnesite and the periclase-spinel products, it is clear that the chrome-magnesite products are penetrated to a greater extent by the iron oxides and SiO 2 than are the periclase-spinel products; the periclase-spinel products are mainly penetrated by iron oxides and to a lesser extent by the SiO 2 while the chrome-magnesite are penetrated by iron oxides and SiO 2 to approximately the same extent; in the chrome-magnesite products, by contrast with the periclase-spinel, the iron oxides are reduced to metal; the main form of the wear in products of both types is flashing, which occurs as the result of the formation of olivine of a complex composition, pyroxene, glass, magnetite, and magnetosioferrite, as observed to a greater extent in the chrome-magnesite products.Thus, in order to further improve the wear resistance of the periclase-spinel products, it is necessary to reduce their porosity and their concentrations of iron oxide and SiO 2. CONCLUSIONSThe interaction between zinc sinters and refractory products has been studied. The greatest resistance to the action of the zinc-sinter melt is found in the articles made from grade PShSP and MChVP products. In this case the structure and porosity of the products are found to have a significant effect on their wear resistance.The wear on chrome-magnesite and periclase-spinel products currently used to line Weltz furnaces is caused by the penetration of the refractory by iron oxides and SiO 2 forming olivine of a complex composition, pyroxene, glass, ferrites, and aluminates and silicates of zinc. In the periclase-spinel products, these processes occur to a lesser extent than in the chrome-magnesite ones.On the basis of the results from these studies it is recommended that the MChVP and PSpSP products be used in the linings of Weltz furnaces; the use of ChM and PSpSO products is not recommended.
