Energy-efficient raw material analysis of Monolithic refractories

Monolithic refractories do not require pre-forming and firing and have become a very important component of refractory materials. Our country has made remarkable achievements in the technological research and development of monolithic refractories. The degree of use of monolithic refractories is getting higher and higher, and the material the basic performance can effectively meet the production work requirements of the domestic high-temperature industry. However, with the rapid development of my country's high-temperature industry, especially after the country has put forward the work requirements for energy conservation and emission reduction in high-temperature industries, the energy-saving work of monolithic refractories is a very arduous task, so the company needs to effectively reduce the furnace. The heat dissipation on the outer surface of the wall can effectively improve the energy-saving work effect of monolithic refractories by increasing the thickness of the furnace wall and selecting thermal insulation materials with low thermal conductivity. The following is an analysis of energy-saving raw material measures for monolithic refractories.

Lightweight raw materials for Monolithic refractories

At present, the preparation methods of the more common porous monolithic refractories and porous ceramics are the same. In these working methods, organic matter will decompose to produce toxic gases. The whole process is relatively complicated, and the economic cost in the early stage is relatively large. At the same time, there are also problems such as large pore size and low strength of the material. After the lightweight treatment of monolithic refractories, the energy-saving work effect of the material can be effectively achieved, especially for the microporous treatment method, which can not only improve the use strength of monolithic refractories but also effectively reduce the thermal conductivity of the material. Based on the slag resistance of the material, the energy loss of the refractory material can be effectively reduced.

Hollow sphere raw material for Monolithic refractories

Alumina hollow spheres are one of the more important raw materials in lightweight monolithic refractories, in addition to the development of magnesium oxide, hollow spheres, glass spheres, and other related methods. By using magnesium oxide hollow spheres to effectively replace alumina hollow spheres, a porous raw material is made. After passing the rotary anti-slag corrosion test, under the same working conditions, the slag loss rate and anti-permeability ability of iron oxide are 5-10 times higher than that of porous materials of alumina hollow spheres. Glass hollow spheres are produced by foaming technology using waste glass produced during glass manufacturing and processing. With the casting material made of this glass hollow sphere, as the external temperature continues to rise, a crystallization reaction will occur between the glass hollow sphere and the matrix of the casting material, which effectively improves the heat resistance of monolithic refractories, and also improves the heat resistance of monolithic refractories. There is a certain expansion phenomenon.

Microporous raw materials for Monolithic refractories

By adding metal aluminum powder and magnesium powder to the clay, the material is synthesized into micropores with just the right bulk density. Metal aluminum is also used as an additive, and zirconia and mullite are used as composite materials. High-strength microporous materials such as mullite, spinel, and forsterite are used, and the pore size of the material does not exceed 10um. By using the in-situ decomposition method, the density of the prepared amorphous material is 1 gram per cubic centimeter, and the raw materials of monolithic refractories mainly indicate calcium aluminates as a light refractory material. After high-temperature treatment, a high-purity microporous material with CA6 as the main component is obtained, and the bulk density of the raw material is 0.70 grams per cubic centimeter.

To effectively achieve the energy-saving effect of non-monolithic refractories, the raw material structure of the material will be transformed from a dense structure to a microporous lightweight structure. The production method can choose the homogenization sintering method.
