Classification and application of mullite insulating bricks

    Mullite insulating brick is different according to the density is divided into light and heavy mullite brick, according to the use of different temperature are divided into: 1350 mullite bricks, 1450 mullite bricks, 1550 mullite bricks etc.

    Performance and application of mullite insulating brick:
    Refractory degree is high, can reach more than 1790 DEG C. Refractoriness under load was 1600 ~ 1700 DEG C. Compressive strength of 70 ~ 260MPa. Good thermal shock resistance. Sintered mullite brick and fused mullite brick two. Sintered mullite brick with high alumina bauxite clinker as the main raw material, adding a small amount of clay or raw bauxite as binder, after molding, sintering and made. Electric cast mullite brick with high alumina, A12O3 and refractory clay as raw material, adding charcoal or coke fines as a reducing agent, after forming by reduction of electric melting method to manufacture. Crystal fused mullite than sintered mullite, thermal shock resistance than sintered products. Uniformity of content in the high temperature properties of alumina and mullite mainly depends on their distribution and glass. Mainly used for blast furnace hot blast stove top, bottom, and glass furnace regenerator, ceramic sintering furnace, petroleum cracking system dead lining.

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 Changxing 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.

Details should understand when patching refractory brick

     Refractory brick most are used in the kiln, but for a long time are damaged, we need to replace it, and the change of refractory brick is not easy in the kiln, the need to pay attention to detail is very much, so today let technical personnel in Changing to tell you dig the refractory bricks need to understand knowledge.

    First, when we replace the refractory brick new needs to the refractory brick broken down, and then replaced with new, need to pay attention to in the refractory brick we had broken, to start from the weakest, then one brick at a time to take, but do not continuously down, when refractory brick with broken to the attention of the kiln body around have loose phenomenon, if have loose would stop or the brick back, when not loose and take, this is what we in the patch kiln refractory brick inside need to pay attention to details.

The second is when we place patching refractory brick alkaline, if the situation is not very good, we can consider replacing the whole site from tire, and so as to avoid distorting phenomenon appears in the repair time.

     The content of the, need to know the details of when patching refractory brick you have some understanding of it, if you want advice on refractory brick more knowledge can consult us

Refractory brick grinder designing needs to follow the rules

Refractorybrick in the production process cannot do without the help of the size and quality of mold, mold determines the quality of refractory brick molding, the following is the principle of making refractory brick shaping mould:

1, the form must be smooth surface, smooth, and have higher hardness.

2, installation of formwork should taper, under the mouth small, big, catchy symmetry, and to ensure that qualified size refractory brick. Taper model after installation is generally 5/1000.

3, uneven surface should be made into a hopper.

4, as far as possible to make the maximum area of the refractory brick as the compression face.

Ditch edge at 5, within the model with radian, template at a corner with L - 2 mm arc.

6, in the event of a mould bottom protruding part, try to make the survival of wedge.

7, the scaling length ratio. The general is according to different kind of brick and clay, is determined by the actual test. At present, China's production of brick, scaling rate is generally 3-4%; length ratio put clay brick for 1-2.5%.

8, thick skin: refractory brick more than 150 mm, should consider two pressures.

Through the above simple introduction I hope can help to you, we produced the high quality and low price firebrick , please contact us if you have the need.

Cause and prevention method of refractory brick burst

Firebrick occurs burst when experiencing thermal shock, the simple reason there is expansion and contraction, and the reason is prone to burst firebrick type as follows:

1.The refractory brick is composed of mineral quartz, tridymite, cristobalite composition, the temperature change is accompanied by a transformation of the crystalline form of the quartz, resulting mutations volume, thermal shock so that the refractory bricks easily burst.

Magnesia or magnesia-chrome brick, due to the thermal expansion coefficient, thermal firebrick burst prevention

1.The use of insulating firebrick, insulating firebrick with insulation due to the role of firebrick inside low stability, not easy to burst.

2.To avoid thermal shock, slow heating and cooling can be effective in preventing refractory bricks burst.

3.Select the heat transfer coefficient is relatively high, toughness good bricks, can reduce the probability of bursting.

Several methods of refractory brick masonry

Refractory brick masonry is divided into: 1, flat bond 2, side wall 3, vertical wall, next we will have a detailed description of these there methods.

1. Refractory brick - laid flat method

Flat wall is mostly for furnace wall, there are a few for the bottom most layer. In China, the most common flat wall, brick wall "with a" bond. Circular bricklaying (like the wall of blast furnace is the bond that).

2. Refractory brick side wall

The side masonry method mainly used in two parts: one is the brick layer, such as the open hearth and the bottom of the heating furnace; two is the side masonry arch, such as the open hearth furnace steel tapping whole arch.

3. Refractory brick - vertical masonry method

Vertical - also called soldier, mainly used in two parts: one is the top bottom, such as the open hearth furnace bottom and furnace bottom; two is the working layer of bottom, such as the open hearth bottom.

As straight standard brick (230x114x65 mm) as an example, laid flat and its maximal plane (230x114 mm). In a horizontal position; side of the side block (also known as the mid plane, 230x65 mm) in a horizontal position; vertical masonry is small (114x65 mm) in a horizontal position
