Although the platelet structure of calcium hexaluminate (CaAl 12 O 19 , or CA 6 ) grains can strengthen and toughen Al 2 3 –MgO–CaO system materials designed in high‐alumina region, it also results poor densification subsequent accelerated slag penetration for refractory application. Considering this aspect, MgAl 4 –CaAl 7 composite was fabricated by solid‐state reaction sintering work, effect ZrO addition on mechanical properties investigated. The showed that presented a more equiaxed...
A calculation model of surface tension for molten slags in SiO2–Al2O3–CaO–MgO systems has been developed the present study, based on a statistical modelling approach. total 832 experimental data have critically selected and used optimization parameters, fairly lower average deviation with 4.60% within applicable composition temperature ranges. And also, dependences discussed using model. The results indicate that tensions always decrease increasing SiO2 content increase MgO content. will temperature.
Equilibrium phase relations in the Na 2 O–CaO–SiO system at <50 wt% SiO concentrations have been experimentally investigated temperatures between 1200° and 1400°C. The liquidus temperature was determined with differential scanning calorimetry. equilibrated samples were quenched high‐pressure nitrogen, examined electron probe X‐ray microanalysis diffraction. Based on experimental results, surface projection has constructed for this range. Six primary fields, Ca 4 , 3 Si O 7 CaSiO 9...
Coal bump refers to a sudden catastrophic failure of coal seam and usually causes serious damages underground mining facilities staff. Considering the combined coal‐rock structure for bumps, process acoustic emission (AE) characteristics coal‐sandstone samples under different loading rates were studied by uniaxial compression tests, three basic modes proneness obtained. The following conclusions are drawn: (1) when rate was relatively low, plastic deformation mass fully developed, while...
A kinetic model of vanadium extraction from the metal bath has been established for describing oxidation behavior different elements including [V], [Ti], [Si], [Cr], [Mn], and [C] in based on a 70 t practical vanadium‐extraction converter. The results show that calculated values using models are good agreement with measured values. calculation also silicon titanium is rapid at initial stage blowing (0–1.5 min), ends after 2 min. intensive happens intermediate stages (1.5–4.5 content...
Nickel slag can be recycled as one of excellent secondary sources due to valuable amounts iron contents. Viscosity CaO–SiO 2 –“FeO”–Al O 3 –MgO system during iron‐extracting process from nickel by aluminum dross is investigated 1723 1873 K. Evolution viscosity and structure are studied with “FeO”/Al ratio decreasing 1.69 0.48. Under the coupling effect “FeO” Al , increases slowly before reduction degree 60% following a significant increase. Structure investigation shows that always acting...
Dissolution rate of limestone in converter slag is a key to evaluate the feasibility slagging mode during steelmaking process. In this work, kinetics dissolution at 1300–1400°C were studied and influence decomposition reaction investigated. The results showed that process can be divided into three stages: stagnation stage, coupling stage sole stage. Higher temperature lower basicity conducive reduce duration time obtain higher degree. was confirmed controlled by chemical reaction, whereas...
Nickel slag can be recycled as one of excellent secondary sources due to valuable iron resource and the thermophysical property CaO–SiO 2 –“FeO”–Al O 3 –MgO system is significant for iron‐extracting process by aluminum dross.
