3.ceramic fiber felt

Ceramic fiber blanket, also known as aluminum silicate fiber blanket, because one of its main composition is alumina, and aluminum oxide is the main ingredient of porcelain, so called ceramic fiber blanket. Ceramic fiber blanket consists of spray type and jilt silk rug type, ceramic fiber jilt silk rug has longer fiber length, its thermal conductivity is smaller and thermal insulation performance is better than spray ceramic fiber blanket. So, Most of the thermal insulation pipeline construction used jilt silk rug ceramic fiber blanket.

The structure of light burning magnesium ball

There are between light burning magnesium powder crystal molecule and a molecule force there, this force is called intermolecular forces. Intermolecular forces and the polarity of the molecules related to the whole molecule is electrically neutral. Because the molecular positive charge and negative charge of electricity power is equal.

Both internal charge distribution situation, the molecule can be divided into polar molecules and non-polar molecules categories.

Each charge, there is a "charge centers", such as positive and negative charge relative position of the center of the "+" or "one" is represented, the positive and negative charges coincide with the center of the molecule is called the non-polar molecules, the molecules do not coincide called a polar molecule.

As q, the distance l, called the product of the two dipole moment p - P.

Forming a refractory material light burning magnesium ball intensity light burning magnesium ball size depends on the structural strength of the internal structure of the organization's role in the size of the force. Theoretically, the process of forming a refractory company light burning magnesium ball strength, mainly two physical and chemical processes.

After extrusion. Light burning magnesium powder diameter of about 0.074mm, molecules or crystal structure was physics.

According to a large number of experimental and theoretical results show that there is interaction between the charge and the charge, the same charge repel each other, dissimilar charges attract each other. Show that the interaction force between two point charges, whose size is proportional to the product of two charges of electricity.

It is inversely proportional to the square of the distance from the charge. Light burning magnesium powder crystal unit there are also an equal amount of positive and negative charges.

In a moment there will always be a dipole exists, this is called an instantaneous dipole-dipole. Intermolecular forces and the polarity of the molecules related to the whole molecule is electrically neutral. Because the molecular positive charge and negative charge of electricity power is equal.

Application and advantages of acid proof brick

Acid proof brick and plate are widely applied in petroleum, chemical industry, medicine-making, food, paper-making, chemical fertilizer, agriculture, pesticide, chemical fibre, textile industry, smelting, and power-generating plants etc., 

 Acid proof brick use quartz, feldspar and clay as main raw material. It is anti corrosion and acid proof material sinterred through high temperature kiln. It possesses features of high acid resistance, low water absorption rate, not easily be oxidized under room temperature, not easily be contaminated by media. The main component of acid proof brick is silica which is kind of Mullite formed by sintering under high temperature, which is a material with high acid resistance. Because its intensive structure, low water absorption rate, it can be resistant against any alkaline medium with any concentration, but it is not resistant to high temperature molten alkali. Refractory material acid brick containing 70% or more silicon dioxide. It is mainly used in chemical industries, such as ditch puzzle acid, acid wells, acid storage library and impacted ground that bears huge acid.

Ladle slide gate damage theory and meaning of conjunction

Ladle slide gate plate mainly contains two types, alumina carbon and alumina zirconium carbon. With steel production increasing and steel quality improving, calcium treatment process is applied, therefore, calcium content in the melton steel increased. Using alumina carbon and alumina zirconium carbon slide gate plate when casting steel, SiO2 and Al2O3 in the slide gate plate would mixed with [Ca], [CaO] in the melton steel or slag and get into low-melting point materials and feldspar, which would cause damage of slide gate plate. This type low-melting point materials would be easy to crushed down by erosion, new low-melting point material would re-appear. This progress would cause the erosion heavier, in which way the slide gate plate would be damaged gradually.

Conjunction of slide gate plate can reduce the number of turnover ladle, low down ladle serves and turnover pressure. In addition, slide gate plate conjunction can low down labor working, improve ladle lining temperature, thus low down casting temperature and bring a number of benefit for production and reducing cost.

From Year 2008, our refractory material factory succeed to develop double conjunction and from Year 2010, triple conjunction is developed. With the triple slide got into the normal production, on-site production, reduce labor intensity, the effect of reducing the cost of generation is very obvious.
