Gas permeable brick for producing carbon baking furnace flame path wall by gold tailings and iron tailings

Abstract

The invention relates to an air brick for carbon calcining furnace quirk wall produced by gold gangues and iron gangues, which effectively solves the problems of utilization of the gold gangues and the iron gangues and bad high temperature resistance capability of the existent air brick. The technical scheme includes using gold gangues and iron gangues as the powder raw materials, bauxite as the bone raw materials, andalusite powder as the shrinkproof agent and SiO2 fine powder as the binder, which are prepared in proportion to produce a mixture material, and then adding CA-70 calcium aluminate cement into the mixture as the delayed coagulant agent, PE fiber as the ignition substance and trimetric sodium phosphate as the plasticizing agent, which are all uniformly cast into the air bricks. The invention effectively solves the problems of utilization of the gold gangues and the iron gangues and high-temperature creep resistance performance of the air bricks, prolongs the service life and creates huge social and economic efficiencies.

Description

1. Technical field [0001] The invention relates to an air-permeable brick, in particular to an air-permeable brick for producing a carbon roasting furnace flue wall by using gold tailings and iron ore tailings. 2. Background technology [0002] Whether it is the gold tailings of the gold processing plant or the tailings of the iron ore, most of them are stored in the tailings ponds and have not been developed and utilized. However, they occupy a large amount of land. If they are not handled properly, they will cause environmental pollution and bring great harm to society. cause harm. The two tailings are composed of a variety of minerals, such as silicate, aluminosilicate, etc., as well as many metal minerals. It also has such as SiO 2 、Al 2 o 3 , CaO and other chemical components, besides, these tailings are stored in a very fine particle state and do not need to be crushed and crushed. They are secondary mineral resources with great potential economic value. People can...

Problems solved by technology

It also has such as SiO 2 、Al 2 o 3 , CaO and other chemical components, besides, these tailings are stored in a very fine particle state and do not need to be crushed and crushed. They are secondary mineral resources with great potential economic value. People can make full use of their physical, The chemical properties turn waste into treasure, but due to the problems in the structure and materials of the existing carbon roasting furnace flue wall, it is easy to creep at high temperature during use, resulting in shrinkage joints, which affects the use of carbon roasting furnaces , then can use gold tailings and iron ore tailings as raw materials to develop new products of breathable bricks to meet the needs of roaster construction and create wealth for the society?
