Critical temperature control: how to add coolant and tone quality Deoxidants lance, temperature and composition of the molten steel to make changes to reconcile, while meeting the requirements of blowing end. The purpose of the temperature control process: to make the process of blowing temperature equilibrium Deoxidants prices, guaranteed to operate smoothly. Stick iron and furnace churn. Somersault stick iron and furnace heats Deoxidants, Deoxidizer should reduce it. Bottom blowing effect is good or bad. Good effect of furnace bottom blowing oxygen scavenger should reduce it. The length of time pressure gun. Long time pressure gun heats, deoxidizer should reduce it. Whether the thermostat before adding cold ball pull carbon. Kallang ball before pulling carbon thermostat heats, deoxidizer should Zhuojia.
