Problems solved by technology

[0003] However, the temperature in the copper liquid pool is generally as high as 1100°C or more. At present, most of the blowpipes used in copper smelting furnaces are iron pipes coated with a refractory protective layer on the surface. The scouring vibration and slag erosion performance of high-speed gas flow is poor, and the refractory layer is rapidly melted and eroded, which makes the metal pipe...

Abstract

The invention discloses a blow pipe for a copper smelting furnace and a manufacturing method thereof. In the blow pipe, one side of a metal pipe is sleeved on one side of a fire-resistant pipe; the sleeved part is sealed by fire clay; a non-fire-resistant pipe is the metal pipe; and the fire-resistant pipe contains the following raw materials in part by mass: 55 to 65 parts of alumina, 20 to 25 parts of magnesia, 10 to 15 parts of active magnesia powder, 2 to 3 parts of zirconia micro powder, 2 to 4 parts of plasticizing agent, and 7 to 9 parts of binding agent. The blow pipe for the copper smelting furnace has the advantages of high-temperature resistance, thermal shock resistance, high strength, resistance to corrosion of gases such as SO2 and the like, resistance to scouring and vibration of copper slag and high-speed combustion-gas flow and corrosion of molten slag, and long service life.

Description

technical field [0001] The invention relates to a blow pipe for a copper smelting furnace and a manufacturing method thereof. Background technique [0002] The smelting of copper needs to go through the stages of charging, melting, oxidation, reduction, casting, etc. In the oxidation stage, the blowpipe is inserted into the copper liquid and blown into compressed air to remove some impurities in the copper liquid. A reducing agent such as heavy oil is blown into the liquid to remove the gas in the copper liquid and reduce cuprous oxide. [0003] However, the temperature in the copper liquid pool is generally as high as 1100°C or more. At present, most of the blowpipes used in copper smelting furnaces are iron pipes coated with a refractory protective layer on the surface. The scouring vibration and slag erosion performance of high-speed gas flow is poor, and the refractory layer is rapidly melted and eroded, which makes the metal pipe oxidize rapidly, resulting in a large a...
