WebGraphite refractory bricks are made of carbonaceous materials and added with a suitable amount of binder to make high temperature and neutral refractory. Material products. The raw materials of graphite refractory bricks include anthracite, coke and graphite, as well as pitch, tar and anthracene oil binders. WebGraphite additions to oxide refractories effectively increase the refractory's thermal conductivity and also improve its thermal shock resistance. As carbon is non-wetted by slag, its presence in the refractory limits slag penetration (Lee and Zhang, 1999; Barthel, 2008; Shen, Fujii, and Nogi, 2009).

WebDec 16, 2015 · High purity (99.8%) fused alumina was mixed thoroughly with synthetic graphite with 5 wt% phenolic resin as a binder. The concentration of carbon in the substrate ranged between 50 and 90 wt%. Refractory substrates were prepared by compacting the mixture in a steel die using a hydraulic press and pressing to a pressure up to 10MPa. WebAug 3, 2016 · The working layer of a ladle furnace unit (LFU) lining made from periclase-graphite refractory is most strongly subjected to the effect of corrosion factors that concern thermal, mechanical, and chemical action. The strongest destructive effect on a lining is the chemical factor. This article provides results of studying the effect slag phase … rcpch feedback form
