Abstract

The invention relates to the field of energy-saving equipment, in particular to a composite furnace wall for a fused magnesite furnace. The composite furnace wall comprises a magnesium castable, a magnesium aluminate spinel porous castable, an anchoring part and a heat-resistant furnace steel shell; the thickness of the magnesium castable is 200-250 mm; the thickness of the magnesium aluminate spinel porous castable is 100-150 mm; one end of the anchoring part is a T-shaped part and is fixed in the castable, and the other end of the anchoring part penetrates through a through hole in the heat-resisting furnace steel shell and then is fixed to a positioning pile on the outer side of the heat-resisting furnace steel shell; a magnesia fire clay connecting part is arranged between the castables; and convex-concave parts are correspondingly arranged at two vertical ends of the castable. Compared with the prior art, the composite furnace wall for a fused magnesite furnace has the beneficialeffects that 1) the furnace wall temperature is effectively reduced, the steel shell temperature is within 600 DEG C, and the working environment of workers is improved; 2) molten metal is prevented from entering skin sand due to overflow of high-temperature melt, and the grade of the skin sand is improved; and 3), the energy loss of the metal furnace shell is reduced.

Description

technical field [0001] The patent of the invention relates to the field of energy-saving equipment, in particular to a composite furnace wall for an electric fused magnesia furnace. Background technique [0002] Fused magnesia is a basic high-quality magnesia refractory raw material prepared by using high-grade magnesite ore as raw material, usually using first-grade or super-grade magnesite as raw material, through electric melting technology and intermittent production methods. It is widely used in metallurgy, building materials, chemical industry and other high temperature industries. [0003] With the rapid development of metallurgical technology, the industry's requirements for the performance of refractory materials are gradually increasing, and the demand for high-grade fused magnesia with uniform structure and structure is increasing year by year. However, the production process of traditional fused magnesia is usually accompanied by the production of fused skin san...
