摘　　要：采用可调气氛高温抗压试验机研究焦炭的高温抗压强度。在高炉实际反应程度范围内,焦炭抗压强度与失碳率呈近似直线关系。失碳率对强度的影响随温度升高而减弱,抗压强度也随温度升高而降低。在此基础上,从理论上分析了高炉用焦炭的破碎机理。Investigating high temperature compression strength of the coke using a high temperature compressive testing machine with adjustable atmosphere.In the range of the practice reaction in blast furnace,the relation between coke compression strength and the carbon lose rate is the close to beeline.The effect of carbon lose rate for strength is increasingly lower along the temperature increasing.And the same with the compression strength.On the base of it,analyze the crash mechanism of the coke for blast furnace...
