Description
This dataset describes the process of crushing 1 kg of raw material during the production of non-metallic metallurgical auxiliaries, yielding 0.832 kg of crushed raw material. This process should be used in conjunction with the production of 1 kg of raw material. The dataset was compiled from data on crushing processes in the production of various metallurgical auxiliaries, with data sources including the production of carbon raisers, exothermic agents, covering agents, and de-siliconizing, desulfurizing, and dephosphorizing agents.
Activity Description
Formed by merging data from the crushing processes of multiple metallurgical auxiliary products, this dataset includes feeding and crushing processes.
Process Description
This dataset provides services related to 'crushing processes, metallurgical auxiliaries, non-metallic materials'. Non-metallic metallurgical auxiliaries refer to various non-metallic materials used in metallurgical processes, with raw materials including ores, ore concentrates, fluxes, flux additives, reductants, calcium oxalate, screened slag, screened slag sand, carbon, etc. This process is compiled from data of crushing processes in the production of various metallurgical auxiliary products. Assumptions regarding the composition of raw materials in this process are made based on material usage: it is assumed that 1 kg of raw material contains 0.4 g of graphite, 0.3 g of calcium carbide, and 0.3 g of lime.

Technology comment
This process refers to mechanically processing refractory raw materials into substances with suitable particle size. Crushing is a technique that applies external forces to the raw material to overcome its cohesive forces and cause disintegration. Commonly used crushing equipment includes jaw crushers, roll crushers, and cone crushers.
