PN series of monolithic purging lances are made from ultra fine power and effective additive according to the theory of tightest piling-up, which show the features of high-strength, excellent thermal shock resistance, superior erosion and corrosion resistance. PN series of monolithic purging lances can be applied for the top purging system solely or together with bottom purging system, and obviously improve the efficiency of smelting and the quality of steel.
