Abstract

The invention discloses a safe and energy-saving smelting furnace body and a smelting device employing same and belongs to the technical field of smelting devices. The smelting furnace body includes ashell and a lining arranged therein, wherein the lining includes a refractory brick layer made of light-weight mullite bricks. The light-weight mullite brick is mainly prepared from, by weight, 40-55parts of aluminum oxide aggregate, 15-20 parts of coal gangue, 5-10 parts of fly ash, 3-8 parts of silicon carbide, 3-8 parts of an expansion agent, 8-20 parts of a binding agent, and 5-10 parts of apore forming agent, the content of Al2O3 in the aluminum oxide aggregate being 40-100%, the expansion agent being at least one of andalusite, kyanite and sillimanite, the binding agent being at leastone of clay and sodium carboxymethylcellulose, and the pore forming agent being at least one of graphite, polyethylene, polypropylene and polystyrene. The smelting furnace body is good in stability,is not liable to be burnt-through and is low in construction cost.

Description

technical field [0001] The invention relates to the technical field of smelting equipment, more specifically, to a safe and energy-saving smelting furnace body and a smelting device using the furnace body. Background technique [0002] Most of the current thermal equipment such as industrial kilns use light-weight thermal insulation refractory materials to achieve the purpose of saving energy and reducing consumption. Among them, mullite lightweight brick is a kind of thermal insulation refractory material that is widely used. It has a large number of pores inside, light weight, stable performance, long service life, and does not produce toxic and harmful gases, which is green and environmentally friendly. [0003] The Chinese invention patent with application publication number CN102276242A discloses a mullite lightweight brick and its preparation method. The mullite lightweight brick uses coal gangue and bauxite as raw materials, plus pore-forming agents, expansion agents ...
