Embodiment Construction

[0007] The gravitational ratio of the electrode anti-oxidation coating composition of the present invention is:

[0008] 1. Boron carbide: aluminum dihydrogen phosphate: copper powder: conductive carbon black = 1:4:1:0.67. The anti-oxidation coating produced by this ratio is used to paint graphite electrodes for zinc smelting and zinc powder.

[0009] 2. Boron carbide: aluminum dihydrogen phosphate: nickel powder: conductive carbon black = 1:4:1:0.67. The anti-oxidation coating produced by this ratio is used to paint graphite electrodes for steelmaking.

[0010] The preparation methods of the above two formulas are as follows: take boron carbide, aluminum dihydrogen phosphate, metal powder, and conductive carbon black in proportion and place them in a vessel, stir at room temperature for one hour, and after standing still for 30 minutes, repeatedly paint on the surface with a brush. The graphite electrode surface is sufficient. The electrode anti-oxidation coating has good co...

Abstract

The invention discloses an electrode antioxidant coating, and the antioxidant coating comprises the following components: boron carbide, aluminium dihydrogen phosphate, metal powder, and conductive carbon black; The manufacturing method comprises the following steps: proportionally weighing boron carbide, aluminium dihydrogen phosphate, copper powder or nickle powder, and conductive carbon black into a vessel, stirring for one hour at normal temperature, allowing the mixture to stand for 30 min, and brushing the mixture on a surface of a graphite electrode repeatedly by a hairbrush. The coating brushed on the surface of the graphite electrode has protective effect, can decrease the oxidation consumption of the electrode side surface by above 50% during application, can greatly decrease the consumption of the graphite electrode per ton of zinc or steel, and can solve the problem of electrode fracture caused by the oxidation consumption of the electrode side surface.

Description

1. Technical field [0001] The invention relates to an anti-oxidation paint used for reducing consumption of graphite electrodes in electric furnace zinc smelting, zinc powder and electric furnace steelmaking industries. 2. Background technology [0002] Graphite electrodes are mainly used in refining furnaces for zinc smelting, zinc powder, and steelmaking. Its function is to guide a large current to the smelting chamber, and generate an arc between the electrode and the charge to heat the charge. Graphite electrodes work in a high-temperature oxidizing atmosphere, and the electrode consumes a lot, mainly due to oxidation. The cost of electrode consumption in production is second only to electricity. At present, measures to reduce electrode consumption in applications generally adopt cooling electrodes, controlling the atmosphere in the furnace, reducing power outage time, etc., but the effect is not obvious. 3. Contents of the invention [0003] In order to solve the def...
