摘　　要：介绍了神木废弃半焦粉生产冶金型焦过程中的无机、有机以及复合粘结剂，研究了粘结剂配方与型焦质量的关系。研究结果表明：聚乙烯醇的加入可以保证型焦的冷态强度，使用聚乙烯醇和水玻璃复合粘结剂效果最佳，其冷态、热态抗压强度可达7．56MPa和3．98MPa。This paper introduced the adhesives in process of making metallurgical formed coke by using Shenmu semi- coke powder, and discussed the relationship between adhesive prescription and formed coke quantity. The results showed that the joining of polyvinyl alcohol can make formed coke keep enough cold - state strength. The optimum effect may be achieved by using complex adhesive made up of soluble glass and polyvinyl alcohol, the cold state and the heat state compressive strength can reach to 7.56MPa and 3.98MPa respectively.
