Title
(EN) GRAPHITE-CONTAINING REFRACTORY ARTICLE AND METHOD FOR MANUFACTURING GRAPHITE-CONTAINING REFRACTORY ARTICLE
(ZH) 含石墨的耐火物及含石墨的耐火物的制造方法
Abstract
(EN)
Provided are a graphite-containing refractory article which has a higher flexural strength and fracture energy than those of conventional refractory articles, and a method for manufacturing the refractory article. This graphite-containing refractory article has a graphite content ranging from 1 mass% to 80 mass%, and has disposed therein a carbon fiber bundle that has a length of 100 mm or more and that is obtained by bundling 1,000-300,000 strands of a carbon fiber having a fiber diameter ranging from 1 [mu]m/strand to 45 [mu]m/strand.
