Abstract

The invention provides a high silicon-ferrum based electrode plate for pickling tank and its making process, wherein the electrode plate comprises Si 14.4-18.0%, C 0.4-0.8%, Mn 0.1-0.8%, P<0.03%, S<0.02%, Cu 1.8-10.0%, RE 0.01-0.05%, and balancing impurity and Fe. Its making process includes alloy smelting, deterioration treatment, cast forming, and thermal treatment.

Description

technical field [0001] The invention relates to an alloy electrode plate for a pickling tank and a manufacturing method thereof. Background technique [0002] After the stainless steel plate is cold-rolled and annealed, there are a certain amount of scale and stains on the surface. Generally, these scales and stains must be removed through surface treatment. Pickling is one of the commonly used surface treatment methods for cold-rolled stainless steel plates. In order to improve The efficiency and effect of surface treatment, using high-temperature sulfuric acid, nitric acid and sodium sulfate solution as pickling solution, pickling in the pickling pool under the condition of electricity, improve the resistance between the pickling solution and the scale and stains on the surface of the cold-rolled stainless steel plate reaction speed. The electrode plate in the pickling pool is soaked in the pickling solution for a long time, and under the condition of low voltage and high...
