High-purity magnesia is an important refractory raw material with a wide range of applications. It is made of natural homogeneous magnesite after crushing, classification, desulfurization and other treatment processes. The main chemical composition is MgO, and the content can reach more than 98%. High-purity magnesia has a series of excellent characteristics, which make it widely used in the refractory industry.
High-purity magnesia has high temperature melting resistance and fire resistance. Its melting point is as high as 2800°C, so it can withstand high temperature and thermal shock, it is not easy to melt and soften, and has good fire resistance. These excellent properties make high-purity magnesia widely used in the manufacture of various refractory materials used at high temperatures.
The magnesia-iron spinel bricks and magnesia-alumina spinel bricks produced by ZHENJIN REFRACTORIES are high-grade refractory materials, which are widely used in high-temperature equipment in the fields of cement, metallurgy, building materials, and chemical industry. These materials are made of high-purity magnesia and other auxiliary raw materials, and have excellent fire resistance, mechanical strength and thermal shock resistance. High-purity magnesia is one of the essential raw materials in the manufacture of magnesia-iron spinel bricks and magnesia-alumina spinel bricks. According to different formulations and production processes, high-purity magnesia can be used in the manufacture of different parts.
First of all, in the manufacture of magnesia-iron spinel bricks, high-purity magnesia is mainly used to make investment patterns and bottoms. The investment pattern is the most vulnerable part of the furnace body, so it needs to be protected with high-quality refractory materials. High-purity magnesia has excellent refractory performance and thermal shock resistance, which can effectively protect the investment mold in the furnace body. The bottom is an important part of the furnace body and needs to withstand greater mechanical and thermal stress. High-purity magnesia can maintain stability in high-temperature and high-pressure environments, and has good toughness and thermal shock resistance, so it is very suitable for making the bottom of the furnace body.
Secondly, in the manufacture of magnesia-aluminum spinel bricks, high-purity magnesia is mainly used in the manufacture of furnace linings, furnace roofs and accumulation areas. These parts are subject to very high temperatures and erosive action, so they need to be protected with high-quality refractory materials. High-purity magnesia has excellent chemical stability and corrosion resistance, which can effectively prevent material erosion and damage. At the same time, it also has excellent thermal conductivity and thermal shock resistance, which can help control the temperature in the furnace body and maintain stability.
High-purity magnesia is widely and important used in magnesia-iron spinel bricks and magnesia-alumina spinel bricks. As one of the important raw materials for advanced refractory manufacturing, high-purity magnesia has excellent refractory performance, mechanical strength and thermal shock resistance, which can effectively protect high-temperature equipment and prolong its service life.
First of all, magnesia-iron spinel bricks and magnesia-alumina spinel bricks have excellent refractory properties. They are all made of raw materials such as high-purity magnesia, which have extremely high melting point, chemical stability and corrosion resistance. These characteristics allow them to withstand very high temperatures and corrosive media such as strong acids and bases, greatly extending the service life of the equipment.
Secondly, magnesia-iron spinel bricks and magnesia-alumina spinel bricks have excellent mechanical strength and thermal shock stability. These materials have a dense structure and fine particle size, so they have good toughness and thermal shock resistance. They can withstand very high mechanical shock and thermal stress, and are not prone to cracking and damage, thus ensuring the safety of the equipment during use.
Third, magnesia-iron spinel bricks and magnesia-alumina spinel bricks are easy to process and maintain. These materials have moderate hardness, good toughness, and are easy to process such as cutting, punching and shaping, so they can be manufactured according to the requirements of various special equipment. Even if there is partial damage during use, it can be easily repaired and replaced.
Finally, magnesia-iron spinel bricks and magnesia-alumina spinel bricks have good economics. Although the price of these materials is relatively high, due to their excellent performance and long life, they can greatly reduce the maintenance cost and downtime of equipment, and have very high economic benefits in the long run.
High-temperature industrial industries need to use refractory materials to protect various high-temperature equipment to ensure their normal operation. Among the many different types of refractory materials, magnesia-iron spinel bricks and magnesia-alumina spinel bricks are one of the main choices. When choosing magnesia-iron spinel bricks and magnesia-alumina spinel bricks, in order to protect various high-temperature equipment and ensure their normal operation. These materials have excellent fire resistance, mechanical strength and thermal shock stability, are easy to process and maintain, and have good economy, so they are widely used in cement, metallurgy, building materials, chemical industry and other fields.
