The principles that magnesia chrome brick manufacturers should follow when choosing refractories for glass kilns. Refractory materials are the material basis of the glass furnace, which directly affects the overall benefits of the furnace. In the glass furnace, the amount of refractory materials is large, and the cost also accounts for the main proportion of the total furnace cost. Therefore, the selection of refractory materials should be rationally configured.

The overall goal of the selection of refractory materials for glass kilns is to comprehensively consider both technical and economic factors, taking into account the physical and chemical properties, structural form and critical performance of refractory materials, the operating environment parameters of various parts of the kiln and the corrosion mechanism of materials at high temperatures. Based on the mutual reaction, we combine the accumulated detailed knowledge and practical experience about the actual operating performance of the furnace and refractory materials, select and match the refractory materials reasonably in each part of the furnace, so as to achieve the equilibrium of corrosion and loss, so as to extend the service life and reduce the cost. The effect of use. Specific requirements are as follows.

The characteristics of this kind of brick are that the raw materials are pure, the firing temperature is high, the high temperature phases such as periclase and spinel are directly combined, and the low melting phases such as silicate are distributed in islands. Therefore, the high temperature of the brick is significantly increased. Strength and slag resistance. The production process of fired magnesia chrome bricks is roughly similar to that of magnesia bricks. In order to eliminate the fine powder produced by MgO, Cr2O3, Al2O3 or calcination of chromium ore-magnesia co-milled compacts during the sintering process of bricks, the method of making bricks with coarse magnesia particles is an effective measure to eliminate the loose effect . Compared with ordinary magnesia-chrome bricks, the magnesia-chrome bricks made by this method have lower porosity, higher compressive strength, load softening temperature and flexural strength. Magnesia-chrome bricks made of chrome ore-magnesite powder compacts and high-temperature calcined synthetic magnesia-chrome sand have better slag resistance and high-temperature strength than other magnesia-chrome bricks.

What refractory materials are good for industrial furnaces?

As a kind of furnace building material, refractory materials are widely used in various industrial furnace linings, with a wide range of varieties, complex uses and diverse shapes. In actual applications, the selection is generally based on the specific use environment and process requirements. According to the operating chemical environment of the industrial furnace: select siliceous materials for acidic environments, magnesia materials for alkaline environments, and alumina materials for neutral environments; in addition to chemical properties, it must also be combined with lining performance requirements, including operating temperature, etc. index.

In order to reduce air pollution and achieve the energy goal of energy saving and emission reduction, most cities have started coal-to-electricity projects, transforming traditional coal-fueled boilers into solid electric heat storage equipment heated by electricity. Among them, in the solid electric heat storage equipment, the heating body is mainly used to convert electric energy into heat energy, and then the heat energy dissipated by the heating body is stored through the heat storage brick. When heating is required, only blow to the heat storage brick through air flow Take out the heat in the heat storage brick and use it for heating.
