In the present study, 35MnVS experimental steels containing nanoparticles are manufactured using a vacuum induction furnace (VIF), as well as a vacuum induction levitation furnace (VILF). The differences on the utilization ratio of nanoparticles (URN), inclusion characteristics, and steel ...
The invention relates to a novel ingot mold for enhancing the quality and increasing the utilization ratio of a steel ingot. The novel ingot mold comprises an ingot mold body for casting the steel ingot, wherein a riser is arranged in the ingot mold body; a heat-insulating groove which ...
1)material utilization ratio材料利用率 1.Introduce the forming technology of compound extrusion for a shell piece, analyzing the material utilization ratio of two processing ways including extruding process and machine work, calculate and design the extrusion piece drawing of a shell part, and design...
Whereas, the second set was designed to explore the effects of a combined steel and synthetic fiber system. The first set of mixes entailed the preparation of seven distinct concrete mixtures. The study's mix design was based on a water-to-cementitious materials ratio of 0.30, targeting a ...
Similar results were also found in [17] that reasonable scheduling of steel mill gases not only reduced peak-valley ratio of the electricity grid, but also brought economic benefits to the steel industry. Zeng et al. [18] expanded the SMGUS with steel mill waste heat recovery units and ...
Adjusting the water-to-binder ratio (w/b) ensures the mixture behaves fluidly and moves smoothly through the delivery system. Once the proportions of sand (and coarse aggregate) and powders, as well as the w/b ratio, are determined, the mix should be optimized for desired characteristics ...
The paste sample was prepared with a water/cement ratio of 0.5, where the required mass of binder (OPC and SSB) and water were weighted and well mixed in a mixing machine for 3 min. The fresh paste was then sealed in a container with a plastic wrap to stop water evaporation and ...
After carbonation, the reacted EAFRS product is successfully utilized as supplementary cementitious materials, with a substitution ratio of 10%, in cement mortar. Additional benefits from using carbonated EAFRS product in cement mortar, such as reduced leaching potentials of heavy metals, enhanced ...
