  • While refractories recycling may have more impact on demand for virgin refractory raw materials due to substitution, there is also an impact on primary refractory demand. Most recycling is of shaped refractories with the aim of obtaining coarse aggregates for reuse in high-quality refractories - in direct competition with virgin raw materials. However, industry participants report that in-situ recycling of monolithic refractories is becoming more common, which decreases the amount of 'primary' refractories that are purchased from third parties. This may help to partly explain the drop in Chinese production of primary monolithic refractories in Q1 2016, which has defied the overall trend over the last decade towards greater use of monolithics due to the speed and ease of their installation.

    The global average consumption of refractories per tonne of crude steel is around 15kg/tonne at present, but there are large variations regionally; in Japan this figure is closer to 7kg/tonne, while in China, Roskill estimates that average consumption is around 20kg/tonne. In 2000, Chinese refractories use in steel production was closer to 30kg/tonne and was still as high as 23kg/tonne in 2008. Chinese consumption of refractories in crude steel production has typically
