摘　　要：定量考察了热解后长焰煤热碎半焦的成形特性。结果表明:热碎半焦具备较好成型潜力,当成型水分25%、腐植酸钠添加量13%、成型压力20 MPa、粒度级配比中低于1 mm比例占65%时,型煤可达到最佳强度393 N。应用热解-成型联合方法可有效解决热碎半焦的利用问题。Quantitatively investigated the molding characteristics of heat fragmentation char of flame coal after pyrolysis. The results show that the heat fragmentation char has good molding property. The best intensity（393 N） can be achieved, when the molding moisture is 25%, the amount of sodium humate is 13%, the molding pressure is 20 MPa, and the less than 1 mm particle size distribution proportion is 65%. The application of pyrolysis-molding joint method can effectively solve the problem of utilization of heat fragmentation char.
