APPROACH TO Zn CONSUMPTION REDUCTION AND SERVIC LIFE INCREASE OF COAL FIRED ZINC BATH

Based on the technological parameter comparison between the domestic coal fired zinc bath and the foreign-made oil fueled zinc bath,factors responsible for such weak points of the former as short service life and high zinc consumption are analyzed.Also presented in the paper are technical measures taken by Bazhou Steel Tube to improve on the service life and zinc consumption of the coal fired zinc bath and the results thereof.
