The effects of intermittent operations


In the process of filling steel-transportation-refining-stop-pouring steel-slag-repair-waiting (preheating) alternately, the temperature of steel package can change from room temperature to 1700 Celsius. Such temperature fluctuations can cause great stress in refractory lining.Refractories are brittle materials at low temperature and are prone to cracks and peeling, which is leading to abnormal loss and reducing the service life of the lining.Therefore, in order to reduce peeling and abnormal loss, we should speed up the turnover of steel package and strengthen the preheating and insulation of steel package, to prevent the temperature drop of steel package waiting for steel connection, which can improve the life of steel package by more than 30%.
