This paper presents a comprehensive study on the behaviors of titanium compounds generated in blast furnace (BF) hearth during vanadium titano-magnetite smelting by dissection method combined with experimental and theoretical analysis. The results show that considerable are formed eroded wall below taphole level. phases consist Ti(C,N) crystals, slag phase liquid iron. crystals mainly TiC0.3N0.7. formation mechanism is revealed. It found within hot metal, while originates from interaction...
The blast furnace campaign life is largely determined by the damage to hearth area. Bricks and skulls in were sampled investigated after blowing-out of one commercial furnace. A variety techniques, such as chemical analysis, scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS), X-ray diffraction (XRD), applied characterizing erosion protection mechanism sidewall. upper area was heavily eroded. Large amounts alkali chlorides identified area, which could be main contribution...
In order to explore effects of element content and temperature on the viscosity, viscosities molten iron were precisely measured by oscillating crucible method. The results obtained are summarised as follows: viscosity rises first then decreases with decreasing temperature; before after turning point property solidification property, respectively. increasing carbon content. increases silicon titanium content; contrary, shows a downward trend manganese, phosphorus, sulphur mechanism various...
The circulation and accumulation of harmful elements in blast furnace were investigated. results show that the maximum concentration K Na belly is about 50 times charge. zinc increased by 80 Pb insignificant. impact K, Na, Zn on fuel consumption was quantitatively analyzed using Rist diagram. gas utilization decreased coke rate linearly with increase load each element. Given element, loading into BF leads to 13.99 kg/tHM, 6.25 3.63 kg/tHM 0.02 respectively. under various loads element estimated.
In order to investigate the dissolution mechanism of carbon brick into molten iron, cylindrical specimens were immersed iron carry out experiments. The reaction was considered as dominant through thermodynamic analysis, result SEM revealed hole diameter decrease from interface center position brick. quantitative relationship between element content and erosion obtained experimental results, characteristic parameters selected compare influence degree on erosion. calculation model mass...
