The invention relates to a method for measuring the heat treatment degree by judging the final temperature of a thermal kiln furnace, in particular to a method for measuring the heat treatment degree of carbon raw material or cathode and anode for aluminium electrolysis in the process of calcining the same with the equivalent temperature correction curves. The method is characterized in that reference raw petroleum coke which is prepared with a certain method is put in a corundum crucible and is buried in the point measuring position of the thermal kiln furnace, then the reference raw petroleum coke is taken out of the corundum crucible after being subjected to the heat treatment in one cycle so that the size of crystal lattice (Lc) of the reference raw petroleum coke is analyzed and the final temperature for calcining the reference raw petroleum coke is obtained by the equivalent temperature correction curves which are drawn in steps with a certain method, and the heat treatment effect of the carbon raw material in the treatment temperature is reflected through the corresponding relationship of the created final temperature and the quality of the carbon raw material, therefore, the heat treatment degree of the carbon raw material by the thermal kiln furnace can be measured.
