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.

The reasons of refractory brick collapse in the process of use
For refractory brick, we may not feel strange. With the progress of society, the application of refractory brick is
more and more widely. Refractory brick appear collapse phenomenon in
the actual using, so what causes it; following the Xinmi Changxing
refractory material factory is simple to give you introduced the
refractory brick collapse reason:
1, red hot refractory brick suddenly quenched with water will rupture and fall.
2, oven heating stage , rate master is not strict, temperature rise too fast, causing severe dehydration, masonry and damage due to expansion and shrinkage.
3, building stove masonry to expand stay insufficient, cracked and falling temperature after expansion.
4, the ash accumulation system, most of the metal salt corrosion of the refractory brick, embitterment of vanadium and nickel will penetrate into the refractory brick falling off caused by.
5 when the liquefied gas, heating, air flow ratio is undeserved, cause furnace blasting and vibration split off.
6, poor air flow furnace, flame directly flush furnace brick, the furnace brick thinning after a serious fall.
7, the operation course lifting furnace temperature pressure to balance, it is strictly prohibited to excessive temperature and pressure, avoid the sharp rise in the drop, because the temperature of each layer of brick always lags behind the furnace temperature, the more rely on the outer temperature changes more slowly, if drastic changes in a short time the temperature of the furnace, brick layer between refractory brick and brick joints rupture is caused due to temperature difference is too large to generate huge internal stress. Furnace pressure will cause the sudden change, refractory brick for each layer of gas pressure can't balance, pressure increasing and destroyed, may cause the whole refractory lining of furnace temperature fluctuation pressure serious collapse.

Refractory performance requirements of blast furnace trough
what are the requirements of blast furnace trough refractories
performance? According to introducing, blast furnace trough is leads to
high temperature molten iron or slag channel. In the production process
to the following destructive effect subjected to several factors:
(1) The refractory material withstands high temperature molten iron and slag flow intense erosion.
(2) The chemical erosion of blast furnace slag.
(3) The destruction of action of thermal shock and intense intermittent iron.
Therefore, the requirements of trough lining refractory material should have the following characteristics:
(1) Trough lining stronger anti high temperature molten iron and slag corrosion and erosion ability of refractory materials.
(2) With anti high temperature performance and excellent wear resistance.
(3) The chemical erosion of stronger anti high temperature slag.
(4) Better thermal shock resistance, small changes in heavy firing.
(5) Against various oxidative ability stronger.
(6) Easy construction, convenient for disassembly and repair, does not produce harmful gases, is conducive to the Protect environment.
Xinmi Changxing refractory exporters introducing the construction method, in addition to the use of blast furnace spray paint, blast furnace ramming material, by using the method of vibration molding or casting molding trough. When using these two methods can not dismantle the trough residues lining, making full use of original trench lining, thereby reducing the consumption of refractory material, at the same time, to improve the working conditions of construction. That can prolong the service life of iron trough.

Steel Flow Initiator
Steel flow initiator is a kind of ladle slid nozzle filler which is successfully developed by our company in recent years, results show that ladle castables success rate of automatic start casting can reach above 95 percent. There is no metallic inclusion in ingot surface, is a kind of ideal ladle slide nozzle filler. Steel flow initiator contains metal mixture whose weight is heavier and melting point is lower than molten steel. Before pouring we put it into upper nozzle, using it to burning and causing the molten steel within the upper nozzle will not be solidified, to achieve the purpose of automatic start casting and avoid the problem of ingot inclusions.
