How to choose suitable refractory brick

Choose our own firebrick is very important, first of all we must understand what is firebrick, refractory bricks and you want to know the parameters and dimensions.
refractory brickWe commonly divided into three main firebricks; the first one is common, ordinary type is one of our more common bricks, the main difference lies in the shape of firebrick less than other entrant. Another is now using more and more, is heterosexual bricks, shaped refractory bricks are also more popular in recent years, a new type of refractory brick, its weight is generally around 16 kg, which is about firebrick itself with three concave corner, shaped refractory bricks are now a lot of very suitable refractory masonry, is also the best choice for most people, and even more groove-shaped refractory bricks than the average of about three firebrick. refractory blockAnother is the standard firebrick, more suitable for this firebrick refractory masonry in general, no special requirements. If there is no special requirements for masonry can choose a standard firebrick.
We can not be at the time of purchase on the types of refractory bricks to choose their own bricks, you can also choose from the color up on the market of yellow and yellow clay firebricks belong, as well as that square brick general observation that species are varied and some relatively bright colors, such as red, brown, white, red, etc., there is usually relatively shallow aluminum brick color white more.
We choose the firebrick or from many different perspectives, I hope you read this article on to choose your own firebrick have some help.

The definition of the fire resistance of refractory material

Refractoriness refractory contend in no load temperature when the utility without melting softening function. Significance and melting refractory degree is not the same. refractoryThe melting point is a crystallization of pure object phase and liquid phase in the flat static temperature. While the ordinary refractory material is composed of a variety of mineral synthesis of multi solid mixture, non congruent melting, but under certain temperatures have liquid, liquid on the proportion unceasingly increases with the temperature rising, to a fixed temperature solid phase can completely melted into a liquid, in a temperature range the two fixed temperatures during the in both liquid and solid, two also exist.
The fundamental decision conditions refractoriness of the material chemical mineral synthesis and distribution. Variety magazine, especially magazine ingredients with strong flux utility, will seriously decrease products refractoriness. Component is not evenly distributed, high melting point of mineral and cannot constitute an ideal, will make the products refractoriness decreased. Ceramic Fiber BlanketNote the, refractoriness does not represent the product using the temperature, because the refractory material in the process often subjected to high temperatures utility at the same time, also with load and material flux effect, so the temperature often are much lower than the refractoriness.
Refractoriness are usually made of cone, pyrometric cone scale representation. Measure refractory refractory experimental approach is: will the tested refractory raw materials or made of refractory fiber products test cone with known refractoriness scale cases in cone, in under the premise of gun and compare test cone and scale of smelting temperature cone bend down, until the test cone top bent the pilot scale contact chassis, and on behalf of the cone bend down the temperature for the test cone refractoriness.
