无黏结剂型煤块配煤炼焦试验研究

Study on Coking Test for Blend with Briquettes without Bonding Agent

利用煤压机压制的无黏结剂型煤块进行炼焦试验,结果表明,随着型煤配量从0到10%、15%、再到20%,焦炭冷热态指标整体呈改善趋势。当型煤配量达到20%时,与型煤配量为0时相比,焦炭的M30改善2.8%、M10改善2.5%,入炉煤多装约3%。在保持焦炭强度不变的基础上,可以通过配用型煤减少价格高的主焦煤配量,达到降低配煤成本的目的。

Briquettes were pressed by tamping machine without bonding agent for carrying out coking test for blend the briquettes. The test results showed that along with the mixing-ratio of briquettes from zero, 10 percent, 15 percent to 20 percent, the quality indexes of coke were improved. Comparing with the mixing-ratio of the briquette in zero, when the mixing-ratio of the briquette is 20 percent, the index M30 was improved by 2.8 percent, the index M10 was improved by 2.5 percent and charged coal was increased by 3 percent about. Based on holding changeless of the coke strength, the main coking coal with high price can be reduced by adding the briquettes, reaching the aim of reducing mixing coal cost.
