【摘要】 研究了在配煤中添加石油焦对焦炭质量的影响。采取配比为5%的不同粒度的添加方案进行配煤炼焦实验,最佳配煤方案与武钢生产配煤焦炭相比,灰分降低0.57%,硫分增加0.02%,抗碎强度基本不变,耐磨强度M10下降0.95%,反应性降低3.12%,反应后强度提高6.59%。焦炭的X-射线衍射对比测试表明,在配煤中加入石油焦能促进焦炭各向异性的发展。更多还原

【Abstract】 The influence of petroleum coke added into coal blend on coke quality is studied. The blending and coking test is carried out with 5% of petroleum coke in different sizes added into coal blend, comparing optimum coal blending proposal with the coke quality produced from coal blend in production of WISCO, coke ash is lowered by 0.57% , sulfur increased by 0.02% , the crushing strength is basically unchanged, the reactivity is reduced by 3.12% , the strength after reaction is increased by 6.59% . It is shown from X- ray diffraction comparison and test, petroleum coke added into coal blend is able to promote the development of coke anisotropy.更多还原
