A temperature controlled high-speed continuous chromium plating technology has been developed.This article compares and analyzes the energy-saving and emission reduction effects of the traditional hexavalent chromium plating process from the aspects of the consumption per ton of chro-mium plated chromium anhydride steel,the consumption per ton of chromium plated electricity per ton of steel,the production of chromium containing wastewater,and the production of chromium plated sludge.The pollutant emission effect of temperature controlled high-speed continuous chromium plat-ing technology:the production of hexavalent chromium per ton of product is 0.52 kg/t,the discharge of chromium containing wastewater is 0.37 kg/t,the unit consumption of chromic anhydride per ton of product is 1.06 kg/t,the discharge of chromic acid mist is 0.005 kg/t,the production of chromium con-taining slag is 0.002 kg/t,and the production of chromium containing sludge is 1.76 kg/t,all of which are safely disposed.
