Abstract:

Steel slag is hydraulic cementing material, which is mainly applicable approach to the production of cement, admixture of high performance concrete, road engineering. But as a result of hydration expansion of the free calcium oxide and free magnesium oxide and dicalcium silicate morphological changes which is contained in slag cause poor stability of steel slag used in engineering, the steel slag utilization is very low. Therefore, the key technology of steel slag treatment process is to improve the stability of steel slag. Steel slag is alkaline slag, with lower temperature, the viscosity inc

Due to the expansion of the nomenclature of steel grades in the industry and the development of new special alloys with increased strength and corrosion-resistant properties, both in the metallurgical industry and in welding, researchers are very interested in the dissolution of nitrogen in metals and slag. Gas permeability of slag is one of the reasons for the appearance of gases in both the base metal and the weld metal. It is determined by two properties: solubility and mass transfer of gases in slag. In addition, in real conditions, the process of dissolving gases in slag is influenced by

Abstract:

In this paper, the effect of titanium carbonitride (Ti(C,N)) on the viscosity of high-titanium-type blast furnace slags was investigated. The different Ti(C,N) contents were achieved by adjusting the reduction degree of TiO2 to reflect the real characteristics of the high-titanium slag. The results show that the viscosity of the slag increased with the increasing Ti(C,N) content and decreased with the rising temperature. A deviation between the measured and the fitted viscosity appeared as the content of the Ti(C,N) was beyond 4 wt%. Furthermore, the apparent viscous flow activation energy of

The utilization of steel slag as resource is very important in the circle economy of metallurgy industry. Because the composition of steel slag is similar to that of the raw materials of ceramic industry, the sintering process of ceramics with steel slag as one of the raw materials was studied, and the ceramic products of high performance were abstained. Based on the study above, the microstructure of slag ceramic and its effect on the performance of ceramic were studied combining the analysis methods of SEM, DTA and XRD and the software FactSage.

As by-product of steeling making, steel slag accounts for 10% to 13% of steel production. Utilization of it as resource has been tried in many fields. For example, it can be used as building materials, most for paving and backfilling. However, utilization level of steel slag is still low, and to find a novel way to utilize steel slag efficiently is urgent. Steel slag includes much calcium and silicon, similar to those of clay, which means that it can be one of the raw materials for ceramic sintering. In this research, the process of steel-slag based ceramics sintering was developed. The cerami

Phosphorous slag, one of the pozzolanic active materials, is a by-product from the production of yellow phosphorous. In this paper, phosphorous slag was ground and adopted to prepare concrete as a mineral admixture. Specific strength method was used to assess the influences of phosphorous slag content on the pozzolannic effects in concrete with different age. The results indicated that with the increase of phosphorous slag content and age, the pozzolanic effects were enhanced in concrete. Phosphorous slag powder is beneficial to the development of long-term strength of concrete.

The slag viscosity decreased with decreasing ZnO/PbO mass ratio because of the depolymerization of the silicate structures. The viscosity decreased with increasing FeOX/SiO2 mass ratio as the experimental temperature was above 1623 K, while the viscosity increased significantly with the increase of FeOX/SiO2 as the experimental temperature below 1623 K because of the phase transition and the change of slag melting point.
