影响焦炭质量的因素分析

焦炭的质量主要取决于配合煤性质和工艺条件。配合煤的性质主要是结焦性、煤的粘结性对焦炭强度的影响较大;炼焦煤的性质影响焦炭的灰分、硫分等化学组成,影响焦炭强度。炼焦的工艺条件是水分、灰分、细度、堆密度等;结焦时间影响焦炭冷态、热态性能和显微特性。 Coke depends largely on the quality of coal with nature and process conditions.With the nature of mainly coal coking,coal coke on the bonding strength of the impact of larger impact on the nature of coking coal coke ash,sulfur grade chemical composition,impact strength of coke.The coking process is moisture,ash,small,bulk density;coking coke cold time impact,thermal properties and microstructure properties
