Preparation of CaO-Al O -SiO system glass from molten

tial heat of molten slag is recovered through a cooling me-dium during the close contact process, which is reserved by heat recovery boiler. Therefore, this process of heat recov-ery is associated with a great waste, such as water waste, leading to the reduced utilization of molten slag. Preparation of glass from slag started in the late 1950s.

Blast Furnace Control using Slag Viscosities and Liquidus

Phase diagrams from literature were studied to obtain an indication of the stable phases under equilibrium conditions for the blast furnace type slag. One such source of ternary diagrams is the Slag Atlas3 in which ternary phase diagrams can be found for the SiO2-CaO-MgO-Al2O3 system with 10% and 15% Al2O3 respectively.

Energies Free Full-Text Preparation of Slag Wool by

A novel method of slag wool preparation from molten BF slag and coal ash by a high-speed air injection method was investigated in the laboratory. The proper liquidus temperature and viscosity of the slag mixture for slag wool fabrication were experimentally studied and the relations of the properties of the slag wool and the process parameters

Slag melting temperature and contact angle on high carbon

A comparison has been made between the synthetic slag results obtained and the CaO-Al 2 O 3-SiO 2 and CaO-SiO 2-MgO-15%Al 2 O 3 phase diagrams [15]. The use of this latter quaternary diagram was due to its similar Al 2 O 3 content with the ES0, ES10 and ES15 synthetic slags.

Use of Blast Furnace Slag Aggregate in Concrete

slag is dependent on the method of cooling and can be produced in the following forms: a) Air-Cooled Blast Furnace Slag If the liquid slag is poured into beds and slowly cooled under ambient conditions, a crystalline structure is formed, and a hard, lump slag is produced, which

Thus, the correct size of electrode for the joint preparation, the correct angle to the workpiece for good penetration and a smooth weld bead profile are all essential to prevent slag entrainment. In multi-pass vertical welding, especially with basic electrodes, care must be taken to fuse out any remaining minor slag pockets and minimise undercut.
