Spring of fire resistant industry

The principle that magnesia chrome brick manufacturers should follow in selecting refractories for glass kilns. Refractory is the material basis of glass furnace, which directly affects the overall benefit of the furnace. In glass furnace, the amount of refractory is large, and the cost also accounts for the main proportion of the cost of the whole furnace. Therefore, the selection of refractory materials should be reasonable.

The overall objective of refractory material selection for glass kiln is to comprehensively consider the technical and economic factors, based on the physical and chemical properties, structural form and critical service performance of refractories, operating environment parameters of various parts of the furnace and corrosion mechanism and mutual reaction of materials under high temperature, and combine the accumulated detailed knowledge and practical experience about the actual operation performance of furnace and refractory The results show that the material selection and reasonable matching of refractories in various parts of the furnace can achieve balanced erosion, prolong service life and reduce cost. The specific requirements are as follows.

Magnesia carbon brick manufacturer

This kind of brick is characterized by pure raw material, high firing temperature, direct combination of periclase, spinel and other high temperature phases, and island distribution of low melting phase such as silicate. Therefore, the high temperature strength and slag resistance of the brick are significantly improved. The production process of fired magnesia chrome brick is similar to that of magnesia brick. In order to eliminate the loose effect of MgO, Cr2O3, Al2O3 or the fine powder produced by CO grinding of chrome ore and magnesia in the process of brick firing, the method of mixing with coarse magnesia particles is an effective measure to eliminate the loose effect. Compared with the ordinary magnesia chrome brick, the magnesia chrome brick made by this method has lower porosity, higher compressive strength, load softening temperature and flexural strength. The slag resistance and high temperature strength of magnesia chrome brick made from chrome ore magnesite powder compacts and calcined magnesia chrome sand are better than other magnesia chrome bricks.

What refractory is good for industrial furnace?

As a kind of furnace building material, refractories are widely used in various industrial furnace linings with various varieties, complex uses and various forms. In practical application, it is generally selected according to the specific use environment and process requirements. According to the operation chemical environment of the industrial furnace, silicon material is selected for acidic environment, magnesium material is selected for alkaline environment, and alumina material is selected for neutral environment; besides chemical properties, the performance requirements of lining, including service temperature and other indicators, should be combined.

In order to reduce air pollution and achieve the goal of energy conservation and emission reduction, at present, most cities have started the coal to electricity project, transforming the traditional coal-fired boiler into a solid electric heat storage equipment. Among them, in the solid electric heat storage equipment, the electric energy is converted into heat energy mainly through the heating body, and then the heat energy emitted by the heating body is stored through the heat storage brick. When heating is needed, it is only necessary to blow the heat to the heat storage brick and carry out the heat in the heat storage brick through the air flow, which can be used for heating.
