DEGREASING AGENT FOR PRETREATMENT OF CONTINUOUS ANNEALING FACILITY AND PRETREATMENT METHOD FOR CONTINUOUS ANNEALING FACILITY USING SAME

摘要

The present invention relates to a pretreatment method for a continuous annealing facility, and a degreasing agent for pretreatment of a continuous annealing facility used for the same. The pretreatment method for a continuous annealing facility comprises: an alkali degreasing step, an electrolyte degreasing step, a rinse degreasing step, and a brush roll degreasing step. The pretreatment method for a continuous annealing facility also comprises: performing a degreasing reaction using a degreasing agent for the pretreatment of a continuous annealing facility at a temperature of 35-45 degrees; and recycling the heat generated in an electrolyte degreasing step in the alkali degreasing step. As such, the pretreatment method for a continuous annealing facility has excellent energy reducing effect, excellent degreasing performance, solution stability, a deposition degreasing property, a fraction acidity property, a water treatment foaming property, and a vesicular property.;COPYRIGHT KIPO 2016
