Abstract：In order to solve the problem of low production efficiency of the heating furnace on the special-shaped production line of the section steel plant,this article applies management tools such as the energy consumption bridge and KAI to carry out on-site diagnosis.According to the site investigation,the main influencing factors include the damage of refractory of the furnace body resulting in heat dissipation and gas escape,improper control of furnace pressure and air-fuel ratio(KAI index),unreasonable sequence/stride of material,high billet weight,and excessive oxidation and burning loss.After taking measures such as repairing the furnace body refractory materials,optimizing furnace pressure and air-fuel ratio adjusting material loading parameters,and improving pipeline insulation,the coal consumption of the heating furnace has approached the design value of 1.38 GJ/t from 1.97 GJ/t,with an annual cost reduction and efficiency increase of about 1.066 million Yuan;the yield has increased by more than 0.14%,and the oxidation and burning loss has decreased by 0.3 percentage points,effectively improving the production efficiency.
