Abstract

The invention relates to an electrode plate used for a corrosion resisting pickling bath and a manufacturing method thereof. The electrode plate used for the pickling bath comprises the following compositions (weight percentage): 0.4 to 0.7 percent of C, 14.5 to 18 percent of Si, 0.3 to 0.8 percent of Mn, less than 0.03 percent of S, less than 0.03 percent of P, 18 to 36 percent of Ni, and Fe andunavoidable impurity as the rest. The method for manufacturing the electrode plate used for the pickling bath sequentially comprises the following steps: firstly, an alloy-used induction furnace or an electric arc furnace is smelted by a double smelting method, then the material is put into the furnace to be smelted, acid slag former which comprises 1 to 3 weight percent of liquid iron is added, and cast iron ingot is cast for reserve; then the cast iron ingot which is smelted and cast in the first time is put into the furnace to be smelted for the second time, and acid slag former which comprises 3 to 5 weight percent of liquid iron is added, when the elements of the liquid iron fulfill the requirement, the liquid iron can be taken out of the furnace after standing for 40 minutes, and then casting and forming are carried out. The electrode plate manufactured by the method for manufacturing the electrode plate used for the corrosion resisting pickling bath has high anti-fracture toughness and is not easy to fracture.

Description

technical field [0001] The invention relates to a method for manufacturing an electrode plate for a corrosion-resistant pickling tank. Background technique [0002] With the development of stainless steel rolling technology and the continuous introduction of rolling production lines for wide stainless steel slabs, the technical requirements for the manufacture of electrode plates for corrosion-resistant pickling tanks for stainless steel sheets are getting higher and higher. The overall size of the electrode plate is increased from 2500mm to 3800mm, and the opening size is increased from 1500mm to 2650mm. The existing electrode plates for corrosion-resistant pickling tanks are ferrite matrix of high-silicon cast iron, there is a phase transition during the solidification process, so phase transition stress is generated, it is a body-centered cubic structure, and this structure has serious low-temperature brittleness , Therefore, resulting in extremely low casting yield.
