Q:Scheme of cement kiln replacing 40 meter refractory brick kiln

If only replace refractory bricks, it just needs three days under the condition of 200 degrees. It will be simpler if there is only free water in the refractory brick (no pouring material).

Q:What is the density of the high alumina refractory brick?

According to the quality, the general level is two point four to two point seven or so

Q:does the electric kiln burner need to be sealed?

seal when open the kiln, and observe the temperature, when the temperature reaches a point, you can move the firebrick away, and continue observing the temperature to decide whether to seal it or not, but do not seal it completely, repeat the procudure until reach the sinter point or skill requirement.

Q:The difference between clay bricks and clay bricks?

Sintering bricks do not have clay bricks, so sintering bricks are made of stone. Clay brick is clay cooking, two yo, qualitative difference, but the appearance and color almost, but the quality is very different, life expectancy is also a great gap.

Q:90 porous brick and ordinary shale brick, clay brick difference

Porous brick is the original clay brick (now don't let in) and shale increased by a certain gap, but it is also the porosity, thickness is 90, not 53 of the original, there are also some differences in the use of solid brick and. Not for underground use.

Q:Characteristics of refractory bricks

The ability to resist rapid changing temperature and not to be destroyed is 6, it refers to the change of the volume expansion and contraction in the same temperature change. the porosity is 3, this parameter is very important in its own properties, anti bending strength, but as a manufacturer, you must strictly control the explicit hole through the material unit area of heat flow rate: The main composition determines the quality and characteristics of the refractory material 2: Unit volume weight, good impact resistance, abrasion resistance show good compactness: Also called high temperature load, it begins to deformation temperature, the volume density, we define such a linear change rate is 0 physical and chemical properties is 1: 5, but the heat conductivity coefficient may be large, load softening temperature, porosity: The ability to withstand shear stress is 8, compressive strength: Did not make specific requirements about thermal shock resistant performance: Resistance to anti penetration erosion under high temperature and not destroyed 7: Don't have to explain it, linear change rate, thermal conductivity, slag resistance: Also known as linear?change?on?reheating or the residual line change, if the expansion and contraction of each time is the same: Under the condition of unit temperature gradient, the service life is 4, chemical composition.

Q:The state's policy on clay bricks

Now the country for the solid clay brick is the policy of emerge of itself and perish of itself. Because solid clay bricks occupy resources, vigorously encouraging new brick, I was open brick reached up to four, but we have to see this with money the disease I do, I don't think they all sold, finally want to engage in a new type of brick, but in the investigation that model free burning brick cost is too high, and a lot of people are not optimistic, finally did not dare to engage in this, we also have the business,

Q:What refractory mortar is better if masonrying 4 meters height and 114 mm width of refractory brick

The selection of refractory mud should keep the principle of homogeneous phase with refractory bricks, that is to maintain the same material, according to the suitable temperature, choose appropriate binding agent compensation measuring forging Yao tic surprised boxing super man (phosphate, sodium silicate, or other organic combination), composite high performance admixture, it can be combined better in high temperature.

Q:What matters should be noticed when using clay refractory bricks in a glass kiln?

There are a variety of products for the production of shaped and unshaped refractory clay, such as blast furnace insulation and high alumina bricks. Brick products include refractory clay bricks, plastic materials for overload, refractory clay and high alumina casting materials, etc.. In the amorphous part, if to support the horizontal induction furnace and the straight induction furnace lining, such as refractory clay and high alumina plastic

Q:can the red brick be used as refractory brick?

1200---1750 of the refractory bricks, below 1000 degrees of red brick brick is ok.
