With the over-exploitation of natural resources in the current industrial production, the problem of resource bottlenecks is very serious, and the raw materials directly used for insulating fire bricks are becoming less and less. Among them, refractory clay is an advantageous resource in my country, and it plays an important role in the production of insulating fire brick. However, due to the current shortage of reserves and the sharp decline in the amount of refractory raw materials, it is urgent to improve the production process of insulating fire brick. should be given high priority. The following is the relevant information for insulating fire brick.
The following is a list of contents:

Mechanical stress damage is the key factor leading to the damage of the insulating fire brick. According to the damage phenomenon of the insulating fire brick, the causes of the damage can be analyzed, and then targeted improvements can be made. In addition, the damage methods of refractory bricks encountered by the company are also different. According to the damage to the insulating fire bricks, combined with the ovality of the cement kiln cylinder, the locking ring, and the construction of the insulating fire bricks, a comprehensive analysis can be carried out. Reducing the damage of the insulating fire brick caused by mechanical factors can prolong the service life of the refractory brick, ensure the efficient and safe operation of the cement kiln, and at the same time achieve the purpose of energy-saving, consumption reduction, and cost-saving.
The advantages of using microbial technology to treat tailings to prepare insulating fire brick production materials are mainly reflected in the following aspects. First of all, the selected strain has high acid production, and the produced acid has a good iron removal effect. It can leach more than 90% of the iron in the tailings. The cost is low, the treatment conditions are mild, and the equipment performance requirements are low. Secondly, the refractoriness of tailings after treatment can reach above 1730℃, which can be directly used as the raw material of insulating fire brick. The tailings in the production of insulating fire bricks are finer in particle size and used for the production of refractory materials, which can save the cost of grinding, and use the residual liquid of biological acid leaching in the cycle to achieve clean production. In the final tailing treatment process, the by-product ferrous bio-acid can be obtained, which can be purified and sold as a product, and by-products with higher added value such as ultra-fine iron oxide powder or iron powder can be developed, which has good economic benefits. Therefore, the use of microbial technology to treat tailings to prepare insulating fire brick can achieve large-scale and high-value-added application goals of bauxite beneficiation tailings.
In this paper, related research has been made on this, and the microbial technology to treat bauxite tailings with low production. The method for co-producing nano-iron oxide with the base material of insulating fire brick is to better improve the production efficiency of the insulating fire brick material. It can improve the softening temperature and refractoriness under the load of the insulating fire brick produced, and reduce the black spots of the product at the same time. The bulk consumption and resource utilization of bauxite beneficiation tailings, the aluminum industry waste residue, can increase the replaceable mineral resources of refractory clay to a certain extent, which has important practical significance for my country's social development and national construction.
All in all, judging from the current actual situation, there are fewer and fewer high-quality refractory materials in our country, which can no longer meet the needs of the current social production of insulating fire bricks, resulting in a huge contradiction between supply and demand. The company must attach great importance to this, according to its nature and characteristics, reasonably select microbial technology for beneficiation and purification, as much as possible to improve the productivity of the insulating fire brick, while reducing the environmental pollution and cost input.
