Case Study

KAlF4 and Salt Cake Added as Fluidizers to Steelmaking Slags

Sweet, G. A., et al. High Temperature Materials and Processes, 2012, 31(4-5), 529-537.

This study investigated the feasibility of using a mixture of salt cake and KAlF4 in slag fluidization applications by measuring viscosity and weight loss at high temperatures (to assess whether significant amounts of potentially harmful gases are formed). A mixture of aluminum salt cake and KAlF4 is suitable for use as a fluidizing agent in terms of fluidity. The results of the study suggest that a mixture of 25% KAlF4 and 75% salt cake must be a suitable replacement for fluorite on an industrial scale.
· Composition of Fluidizers
Both KAlF4 and salt cake fluidizers were evaluated in a master slag (CMS) made up of 40 mass% CaO, 30 mass% SiO2, and 10 mass% MgO, with comparisons made to a baseline slag that utilized traditional fluorspar as a fluidizer. The specific compositions of these salt fluidizers can be found in Table 1.
· Preparation of Slag
Initially, a master slag (CMS) was created by combining powders of CaO, MgO, and SiO2. Afterward, the master slag was mixed with a fluidizer. The composition of this slag was designed to reflect that of a typical steelmaking slag, maintaining the same proportions as previous research: 40 wt% CaO, 30 wt% SiO2, 10 wt% MgO, and 20 wt% fluidizer. To improve particle interaction and enable the samples to fit into the crucible, they were subsequently compressed using a cold isostatic press (CIP).

The Effect of KAlF4 Flux on the Sintering Process of Aluminum Powder

Narva, V. K., et al. Russian Journal of Non-Ferrous Metals, 2007, 48, 475-477.

Porous powder materials have been successfully used in aerospace engineering, agriculture, mechanical engineering, medicine, nuclear power engineering and instrument manufacturing. The effect of KAlF4 flux and its particle size on the sintering process of PA-4 aluminum powder was studied.
· The process by which the KAlF4 flux spreads across the surface of aluminum during sintering has been established. When in a molten state, the KAlF4 flux effectively dissolves viscous oxides (Al2O3) from the aluminum particle surfaces, preventing further oxidation. It also wets the surfaces of the components, facilitating the free spread of silumin over the aluminum particles and helping to bind them together. Upon cooling, the flux remains as a thin, closely adhering film where the particles make contact.
· The effectiveness of the flux is influenced by its particle size. For aluminum particles larger than 60 µm, it is advisable to use a flux with a particle size smaller than 50 µm, maintaining a total concentration of 1-3%.
· Sintering in air at a temperature of 600°C for 15 minutes results in a sample porosity ranging from 21% to 41%, with a strength between 6 and 21 MPa, when the aluminum particles have a size distribution of 46-100 µm.
