The technological progress of glass furnace puts forward new requirements for silicon bricks: Due to the long-term work under high temperature load, the silica bricks of the glass melting kiln have different softening degrees on different thicknesses. Therefore, it is important to use high-quality silica bricks for the melting kiln.
The role of the mineralizer is to accelerate the transformation of quartz into low-density quartz variants (tridylquartz and square quartz) during firing without significantly reducing its refractoriness. It also prevents loosening and cracking of silica brick adobe due to rapid expansion during firing.
The refractory degree of general refractory bricks indicates its high temperature resistance. However, high refractory is not necessarily a high-grade refractory brick, and other properties should be comprehensively considered. This situation will be encountered when refractory bricks are used in glass pool furnaces. Even refractory bricks with low refractory degrees are used for better results.
1. Silica brick for coke oven Silica bricks for coke ovens are used to masonry silicon refractory products of coke ovens with pyroquartz as the main crystal phase. Modern coke ovens are large-scale thermal equipment built with tens of thousands of tons of nearly 1,000 kinds of brick-type refractory materials, of which the amount of silicon bricks accounts for 60% -70%. Coke oven silicon bricks used in masonry coke oven silicon bricks should have the following characteristics:
A glass furnace is a thermal equipment for melting glass composed of refractory materials. When choosing refractory materials for glass kilns, the type of kiln, the location of use, the damage mechanism, the variety of fused glass and the type of pigment should be considered. Refractories for glass kilns should first be able to resist the erosion of glass melts and gaseous agents, and should have a sufficiently high load softening temperature and thermal stability.
A common problem that has plagued users of continuous operation of glass kilns in the glass manufacturing industry since the beginning is that glass kilns have a short service life. In order to extend the life of glass kilns, a lot of research and development work has been carried out.
High-quality silica brick is a kind of refractory mouth. It is made of silica as the main raw material. Human mineralizers and binders will be added in the process of processing, such as iron, phosphorus, lime milk and sulfite pulp.
The purchasing staff of many enterprises will always pay special attention to his price when purchasing high-quality silicon bricks, and want to know how much this material needs, but the price of high-quality silicon bricks is not fixed when they are sold in the market, because it can be divided into many different types according to different shapes.
High-quality silicon bricks have a very wide range of uses in daily life, especially in some special processing enterprises, this material is often used, but when purchasing this material, people are a little confused and do not know where to go.
Nowadays, it is very common to use AZS fused brick companies. With the continuous discovery of sustainable technology, this product has also been applied in different industries. So what are the famous AZS fused brick companies in China now? Next, the editor will introduce this issue to you, hoping to bring help to the relevant people.
