Refractories For Blast Furnace Body

The refractory industry is an important basic industry serving high-temperature technology and is particularly closely related to the iron and steel industry, ceramic industry, and glass industry. The new development of the high-temperature industry, especially iron and steel smelting technology, has promoted the technological progress of the refractory industry. The technological progress of the refractory industry has guaranteed the implementation of new technologies in the high-temperature industry. The stable production, high production, and long life of various kilns in the iron and steel industry are inseparable from refractory materials. Due to different uses and conditions of use, various kilns have different requirements for refractory materials that constitute their main bodies, and different types of refractory materials are also different. Due to the difference in chemical composition, microstructure, and production process, it shows different basic characteristics. Therefore, it is necessary to understand the basic properties of refractory materials to understand and study refractory materials for industrial kilns. On this basis, this article focuses on refractories for blast furnaces and hot blast stoves. The blast furnace is the main equipment for ironmaking. It has the advantages of large output, high productivity, and low cost, which is unmatched by other ironmaking methods. With...

Refractory Bricks: The Foundation of Industrial Safety

Refractory bricks are a crucial component in industrial settings where high temperatures and harsh conditions are commonplace. These bricks, made of ceramic materials, can withstand extreme temperatures and are used to line furnaces, kilns, and other high-temperature equipment. They are essential for ensuring the safety of workers and preventing catastrophic accidents. One of the main benefits of refractory bricks is their ability to resist thermal shock. Thermal shock occurs when a material is rapidly heated or cooled, causing it to expand or contract quickly. This can lead to cracking or even the complete destruction of the material. Refractory bricks are specially designed to resist thermal shock, making them ideal for use in high-temperature environments. In addition to their thermal shock resistance, refractory bricks also have excellent insulation properties. This allows them to maintain a consistent temperature within the equipment they line, which is essential for ensuring that the equipment operates efficiently and safely. Insulation also helps to prevent heat loss, which can save energy and reduce costs. Refractory bricks come in a variety of shapes and sizes, which allows them to be customized to fit specific applications. They can be made into different shapes, such as curved, flat, or tapered,...

What Are the Properties of Refractory Bricks?

1. Refractoriness According to the refractoriness, refractory bricks can be divided into ordinary refractory bricks with a refractory degree of 1580-1770 degrees Celsius; advanced refractory bricks with a refractory degree of 1770-2000 degrees Celsius; special-grade refractory bricks with a refractory degree greater than 2000 degrees Celsius. 2. Porosity Generally, those with a porosity of about 3%-10% are called high-density refractory bricks, those with a porosity of about 20%-30% are called ordinary dense refractory bricks, and those with a porosity of 45%-48% are called lightweight refractory bricks. 3. Load Softening Temperature Refractory bricks can withstand a constant pressure load and produce deformation temperature at a certain heating rate. He said that the resistance of the refractory bricks to high temperatures and load at the same time. 4. Slag Resistance Acid refractory bricks have a strong ability to resist acid slag erosion, alkaline refractory bricks have a strong ability to resist alkaline slag erosion and neutral refractory bricks can resist both acid slag erosion and alkaline slag erosion. There are many types of refractory bricks, and choosing the right refractory bricks also has an important impact on the service life of the kiln.
