Causes and solutions of oxide scale bulging on HRB500E steel bars surface
Reasons for oxide scale bulging on HRB500E steel bars surface were analyzed and studied,and it was found that reasons were high final rolling temperature,insufficient water penetration capacity after rolling,slow cooling speed,and low water pressure were not enough to penetrate steam film on steel bar surface,resulting in water vapor contact with high-tem-perature steel bars.Solution is to improve water penetration intensity after final rolling,increase water volume,reduce gen-eration of water vapor and eliminate it in time by transforming water penetration equipment after rolling,adding anti-water penetration protective cover and a special exhaust chimney;Optimize rolling process,reduce temperature of cooling bed,e-liminate phenomenon of oxide scale bulging on steel bar surface,and improve product quality.
