Composition and properties of magnesia brick

Magnesia brick is magnesium oxide containing not less than 91% and calcium oxide not more than 3%, alkaline refractory products that percales are the main minerals.

Magnesia brick phase composition of percales 80%­—90%, magnesium ferrite (MgO • Fe2O3), magnesium olivine (2MgO • SiO ₂) and calcium magnesium olivine (CaO • MgO • SiO ₂) a total of about 8% to 20%, magnesium, calcium, iron and other silicate glass about 3% 5%. these silicate may containing three calcium silicate (3CaO • SiO ₂), MERWINITE (3CaO • MgO • 2SiO ₂), calcium and magnesium olivine, forsterite, two calcium silicate (2CaO • SiO ₂) etc..

Magnesia brick characteristics: good heat conductivity; thermal expansion; resist alkali slag resistance, resistance to acid slag properties; load deformation temperature because of percales grains surrounded by silicate cement of low melting point, is the starting point is not high, but the collapse temperature and starting point of difference; refractory degree higher than 2000 ℃. But there is no significance for practical use; poor thermal stability is the main reason for the destruction of the general use. In the storage and transportation; should pay special attention to moisture proof; from back after the break easily.

How to introduce the refractory brick density to others

When customers purchase firebrick from us, and we certainly have to introduce them a range of knowledge about firebrick, and the density of firebrick most need to know, let Yilong technician to tell you how to introduce customers firebrick density.

Firebrick densities are based on different raw materials to the decision, because if the density of refractory bricks are the same, then it shows all aspects of the refractory bricks are the same, so if we choose firebrick, what does that mean? The density of the refractory bricks so we made ​​a classification according to the material used in refractory bricks. The density of the refractory bricks and refractory bricks may also be resistant to some of the impurities in the outside world.

Refractory bricks density of different materials:

Ordinary firebrick: 1.8 ~ 2.0g / cm3

Dense firebrick: 2.05 ~ 2.20g / cm3

Silica brick: 1.80 ~ 1.95g / cm3

Magnesia brick: 2.60 ~ 2.70g / cm3

Alumina magnesia brick: 2.90 ~ 3.00g / cm3

Alumina bricks: 2.25 ~ 2.30g / cm3

Comprehensive above described, for the density of refractory bricks knowledge you have some understanding of it, so you know how to introduce others firebrick, if you want to ask for more knowledge about the firebrick remember to consult us.

How to remove the refractory on the castable furnace

Castable after prolonged contact with thermal furnace wall, they will have chemical reaction, penetrate the lining, causing damage or corrosion of furnace lining, then how to deal with the furnace refractory castable on a lot of people became troublesome problems. Today, our experts will give you a brief introduction on the furnace refractory castable removal methods.

When removing the refractory castable, we must first understand the environment and the surrounding thermal furnace refractory castable life. In the demolition process refractorycastable, we should be careful not to make dust, debris, and other impurities mixed adhesion refractory castable, in order to avoid physical and chemical reaction to produce other good clean impurities. Moreover, we need to dismantle down the different categories of refractory castable, remember not to arbitrarily debris piled together. Construction workers also pay attention to put a dust mask or respirator when removing refractory castable avoids debris into the eyes, nose and mouth.

Here, we simply introduce a bit on the furnace castable refractory removal method, if you want a better understanding on the furnace refractory castable removal methods, you can log on to our website can also call our service sales Hotline.

Different boiler need different refractories

we have known using of refractory material boiler knowledge, but the boiler in different request of refractory materials are not the same, today let technicalpersonnel Yilong to tell you different boiler need what refractories.

Boiler generally the most commonly usedrefractories are power generation boiler and boiler. Power boiler refractory material, according to its component is different, different temperature, so the choice of refractory materials to match. So power refractory boiler used mainly for unshaped refractory lining. Refractory material general should be placed in the burner and burner and other parts, but due to the existence of the temperature is too high, recommended to choose high alumina or refractory clay; on the other hand is the ordinary boiler refractory material, the common boiler is composed of furnace tube system and combustion chamber and other parts, the existing working pressure is not high, but also need to withstand high temperature, so we choose the clay brick level inside, the rest three level brick. So boiler using different refractory brick is also different, we must choose the refractory brick for the boiler according to the nature of the boiler.

The content of the boiler, for the different selection of refractory material requirements of knowledge you have some understanding of it, if you want to know more about the refractory material knowledge can consult us freely.

Selection and using of refractory brick

We all know that in the refractory brick selection time not only to understand the specifications, but also to understand its use in those aspects, at the same time should understand how to buy after inspection, this knowledge is much novice distress, today let technical personnel Yilong to tell you.

Refractory brick of species, which is mainly used to refractory clay and other made of refractory materials, color is light yellow and the pale brown, is mainly used for masonry smelting furnace, high temperature resistant, so called firebrick. When we want to know the specification is very much on the choice, we want to compare and make a decision, there is the specification must be consistent with the provisions of the state and the relevant departments, but also to carry out inspection, must not be careless when we want to have a look Is it right? Acceptance and our initial order the same, but also randomly selected several blocks out have a look, to avoid damage.

And we all know that there are many kinds of refractory brick,according to the different nature of each species, can be used in many related industries. The most commonly used industry is steel series, series, rotary kiln stove series, in the steel industry using refractory brick is to prevent the furnace or eruption out to cause some damage, so to use in the fire mouth, block the fire out; refractory brick in rotary kiln is used in lining of use inside, the protection of the kiln body safety; hot blast stove series is in refining device, pre buried iron etc. mainly using refractory brick.

The content of the refractory brick, for the knowledge you have some understanding of it, if you want to learn more about refractory brick can always consult us.  http://www.chinafirebrick.com

Refractory castable antacid effect

Acid castable antacid effect has this condition is necessary, but a people that new into castable industry will tangle what is acid castable antacid effect, today let Luoyang Yilong technician tell your knowledge about acid castable acid resistance on this issue.

Castable acid erosion resistant to acidic waste, is castable greatest protection, but what is called acid castable antacid effect is because of the existence of castable surface pores more, but will be lower porosity and high temperature mechanical properties other castable it will be much higher compared; acid castable and construction in the use of time, as long as they meet a large range of acidic waste can be a good resistance, and when the casting material which adds a certain amount of bulking agent when it will not affect the acid resistance castable acid, while ensuring overall castable is not compromised, but the overall acidic waste will not be reduced, so the acid castable antacid effect in the construction time can be more well reflected.

Comprehensive above, knowledge of what is acid resistant castable antacid effect you have understand, if you want to know more about castable knowledge can contact us.
