Protection of Blast Furnace hearth lining by the addition of TiO2 . Thermodynamic calculations indicate that TiO2 is in euilibrium with titanium carbonitride in the slag at the tuyere level when the slag TiO2 Ti after reduction from TiO2 precipitates into HM and reacts with carbon and nitrogen to form titanium carbonitrides which forms
A KINETIC STUDY OF CARBON INJECTION INTO ELECTRIC ARC FURNACE SLAGS 399 Introduction Slag ing has been extensively studied because of its importance in many pyrometallurgical processes12. In the Key words: carbonslag reaction, kinetics, slag ing. Figure 1. Schematic of carbonslag reaction Gas CO CO2.
The resulting titanium slag generally contains 40 wt % to 50 wt % TiO2. Get Quote; Research on the Titaniferous Slag Smelting Process and Furnace. The coke has low reducibility but it is used widely in titanium slag smelting conductivity, largescale reserves, a high carbon
In order to better evaluate the application of graphite electrode in large scale titanium slag furnace, this paper focuses on the comparison and analysis of ordinary and highpower graphite electrode from the aspects of main parameters of electrode, selective application test of electrode and cost, so as to find the type of graphite electrode suitable for large scale titanium slag furnace.
Titanium is one of the most valuable elements found in blast furnace slag, with a concentration of approximate %. Because of the low level of titanium in slag, the best method of extraction is hydrometallurgy. In this study, parameters such as slag particle size, temperature, concentration of acid, solidtoliquid ratio, and ultrasonic wave time were used to determine the recovery of

Groundgranulated blastfurnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing
Titaniumbearing blast furnace slag is carbonised in the nitrogen plasma. With the sample of slag held for 1h in the plasma furnace at 1700, 92% TiO2 in the slag can be transformed into TiC(N) and the diameter of 40% TiC(N) crystalline is more than 20 m. Carbonized slag is separated by weightdressing. As a result, the concentrate is obtained which contains TiC(N) of more than 50%, and
Request PDF | Carbonthermal reduction nitridation of blast furnace slag bearing titanium | Utilization of blast furnace slag bearing titanium is a key project. A new approach to utilizing the
#0183;#32;Roasting experiments for titanium slag were conducted in a muffle furnace (YFX12/16QYC, Shanghai, China). Firstly, g of Panzhihua titanium slag was selected by an electronic balance and then placed in a ceramic crucible, followed by introduced the slag samples into a drying oven.
