Problems solved by technology

However, due to its relatively high silicon and chromium content, it is also difficult to produce and the quality of castings is difficult to guarantee.
At present, the high-silicon cast iron anode produced by the conventional process has low strength, is easy to break, has poor impact resistance, weak corrosion resistance, and high anode consumption rate.

Abstract

The invention discloses a production technological process of a solid rod high silicon cast-iron anode. The production technological process comprises the specific steps of mold heating, sand mould manufacturing, box closing, box burying, alloy smelting, casting, aftertreatment, assembly, boxing and goods delivering. During sand mould manufacturing, a rod model is heated, specially-made precoated sand covers the model according to a certain thickness, a cover plate is closed, then, heating is carried out, and after sintering molding is carried out, a sand mould is taken out to be cooled; during box closing, an inner sand core is contained in the sand mould, buckling is carried out, and then a box is buried in casting sand; and during alloy smelting, alloy materials are put into a smelting furnace to be smelted according to the proportion and the sequence, refining is carried out, and gas and impurities in a molten alloy are removed. The high silicon cast-iron anode has the beneficial effects that internal grains are dense, uniform and fine, and the outer surface quality is excellent; and the mechanical strength and the impact resistance of the anode are greatly improved, the corrosion resistance is improved, the consumption rate of the anode is reduced, and the process has the good economic benefits in cathode protection application.

Description

technical field [0001] The invention relates to the technical field of cathodic protection systems, in particular to a production process flow of a solid rod high-silicon cast iron anode. Background technique [0002] Solid rod high-silicon cast iron anode is used as an auxiliary electrode for impressed current cathodic protection. It uses the principle of electrochemical corrosion to inhibit the corrosion of steel structures. ) etc. form an electrical circuit. The silicon content of high-silicon cast iron anode reaches about 15%, and a certain amount of chromium, manganese, carbon and other elements are added to make it very superior in corrosion resistance, and its stability in cathodic protection is also very good, becoming a high-quality anode auxiliary anode. However, due to its relatively high silicon and chromium content, it is also difficult to produce and the quality of castings is difficult to guarantee. At present, the high-silicon cast iron anode produced by t...
