Sentence examples for hot slag from inspiring English sources
Her arms, like those of many women shipyard workers, still bear tiny white scars from "metal sparkles," hot slag that fell into her sleeves and gloves as she welded overhead.
Utilization of hot slag and its waste heat (1450 1650 °C) constitute a great challenge for iron and steel industry.
Experiments to investigate the effect of different process parameters on temperature distribution in the furnace and preparation of glass-ceramics from the modified hot slag were conducted.
During the process, composition and structure of hot slag are modified to meet the need of target materials, while its waste energy is utilized to lower heat consumption during the melting and reactions of raw materials.
To achieve efficient flow ability and take advantage of more hot slag, the steel slag was modified to include a higher basicity (CaO/SiO2) of 0.6 0.7 compared to the traditional product (commonly below 0.5).
However, the multimodal powder was more effective in workability than the unimodal alumina, so the bulk density was greatly increased and apparent porosity was decreased as shown in Figure 2. Reduction of the apparent porosity of the castable should lead to a lower hot slag and metal penetration, reduced spalling, and therefore, increased lining life in steel-making applications.
The integrated CO2/sludge gasification using the waste heat in hot slags, was explored with the aim of syngas production, waste heat recovery and sewage sludge disposal.
These deciphered results appealed potential ways of reasonable disposal of sewage sludge and efficient recovery of waste heat from hot slags.
The results demonstrated that hot slags presented multiple roles on sludge gasification, i.e., not only a good heat carrier (500 950 °C) but also an effective desulfurizer (800 900 °C).
Cold air is used to recover heat from hot solid slag granules in the heat exchanger.
The results showed that bio-oil production by pyrolysis of biomass using waste heat from hot BF slag was reliable.
