Problems solved by technology

In addition to objective reasons such as process technology and equipment, the low proportion of recycled refractory materials and the lack of corresponding recycling technical standards to regulate and guide are also factors that make it difficult to further reduce the unit consumption of refractory materials.
The simple treatment of a large number of waste refractory materials not only pollutes the environment, but also wastes resources. How to use waste refractory materials to standardize the production of products without affecting the service performance and life of the products is a common issue for refractory manufacturers.
[0003] High-strength anti-aluminum penetration castable is a refractory castable used in aluminum melting furnaces. Aluminum melting furnaces are high-temperature heating furnaces used in the aluminum processing industry. They are used to melt aluminum ingots or scrap aluminum. The operating temperature is 800-1000 ° C. The temperature is much lower than that of the iron trough, but because aluminum is a very active metal, and aluminum alloy contains many active elements, such as Mg, Mn, Si, Zn, etc., these active elements are easy to mix with refractory materials. Some of the components in the reaction react, causing the material to peel off, which is the main reason for the damage of this refractory material

Abstract

The invention relates to the field of refractory materials, in particular to a high-strength aluminum-resisting permeable castable as well as a preparation method and the application thereof. The high-strength aluminum-resisting permeable castable is prepared from the following components in parts by weight: recycled corundum, a brown fused alumina powder, an alumina powder, cement, a silica powder, barium sulfate, a carborundum powder, a dispersant and an explosion-proof agent. The high-strength aluminum-resisting permeable castable provided by the invention has the advantages of good construction performance, moderate hardening speed, good use performance, high strength, good wear resistance, good aluminum corrosion resistance and good thermal shock resistance; the high-strength aluminum-resisting permeable castable can be applied to various refractory environments which need high-strength aluminum-resisting permeable ability.

Description

technical field [0001] The invention relates to the field of refractory materials, in particular to a high-strength anti-aluminum penetration castable and its preparation method and application. Background technique [0002] At present, the output and consumption of steel and refractory materials in my country rank first in the world. Although the consumption of refractory materials per ton of steel (iron) in the iron and steel industry has been declining in recent years, there is still a huge gap with the world's advanced level. In addition to objective reasons such as process technology and equipment, the low proportion of recycled refractory materials and the lack of corresponding recycling technical standards to regulate and guide are also factors that make it difficult to further reduce the unit consumption of refractory materials. The simple treatment of a large number of waste refractory materials not only pollutes the environment, but also wastes resources. How to us...
