Problems solved by technology

[0002] At present, most of the refractory materials are used for the protective layer of the copper melting furnace blowpipe. The proportion is unreasonable, the structure is loose, and it does not contain steel fibers. The refractory indicators cannot meet the requirements, so that the average life of the blowpipe is about 1 hour. , the consumption of a ton of steel pipe is about 300 yuan

Embodiment 1

[0010] The refractory materials are selected according to the following weight ratio: alumina aggregate 27, magnesium oxide fine powder 70, asbestos wool 2.8, steel fiber 12, sodium silicate 10 with a density of 12, and the above raw materials are fully mixed.

Embodiment 2

[0012] The present invention can select raw materials according to the following weight ratio: alumina aggregate 30, magnesium oxide fine powder 72, asbestos wool 3.0, steel fiber 1.5, sodium silicate 11 with a density of 13, and the above raw materials are fully mixed.

[0013] The alumina aggregate can be replaced by high alumina vanadium clay containing more than 85% alumina. Sodium silicate can adjust its reasonable density by water.

[0014] The refractory material in the above embodiments can be evenly applied to the outside of the blowing pipe by a vibrating machine to form a protective layer, and after drying in a drying room, a waterproof film is added for use.

Abstract

A refractory material for the protecting layer of blowing pipe used in copper smelting furnace is prepared from aluminium oxide as aggregate, fine magnesium oxide powder, asbestos wool, steel fibres and sodium silicate through proportional mixing. It can elongate the average service life of said blowing pipe.

Description

Technical field [0001] The invention belongs to a refractory material, and mainly relates to a refractory material for a protective layer of a blow pipe of a copper melting furnace. Background technique [0002] At present, most of the refractory materials are used for the protective layer of the blowpipe of the copper melting furnace. The proportion is unreasonable, the structure is loose, and it does not contain steel fibers. The refractory indicators cannot meet the requirements, so that the average life of the blowpipe is about 1 hour. , The consumption of a ton of steel pipes is about 300 yuan. Contents of the invention [0003] The purpose of the present invention is to provide a refractory material for the protective layer of the blowpipe of a copper melting furnace, which is applied to the outside of the blowpipe to form a protective layer, which can improve the oxidation resistance and fire resistance of the blowpipe and reduce pipe consumption. [0004] The obje...
