Kaedah pengiraan masa pegangan bahan kerja dalam relau elektrik eksperimen

For the heat treatment of the workpiece in the experimental electric furnace, the commonly used formula for calculating the holding time is t=α·K·D

Di mana:

t——Holding time (min);

α——pekali pemanasan (min/mm);

K——Pekali pembetulan apabila bahan kerja dipanaskan;

D——Ketebalan berkesan bahan kerja (mm).
