Thermal conductivity represents the amount of heat per in unit area, unit time and unit temperature gradient in the energy transfer process.</p><p><br /></p><p>At 1000 ℃The thermal conductivity of various <b><i><a href="http://www.chinafirebrick.com/Fire-Brick11.html" target="_blank">refractory bricks</a></i></b> rate as shown below. The thermal conductivity of different materials is often very different. At normal temperature, the thermal conductivity of various refractory bricks can be from a few percent to several tens (w/(m℃), which is nearly a thousand times lowst than the highest value. As the temperature rises, although the difference between the thermal conductivity of various refractory bricks tends to decrease, but the difference is still large. Such as 1000 degrees centigrade, the thermal conductivity of lightweight silica is only about 0.35W, recrystallized silicon carbide products is about 17.5W/(m℃), graphite can be up to 35W / (m℃).</p><p><br /></p><p>In addition to temperature, the thermal conductivity of <b><i><a href="http://www.chinafirebrick.com/" target="_blank">refractory material</a></i></b> bricks is closely related to its chemical composition and structure. When refractory bricks are made of crystal, the properties of crystal have obvious influence on thermal conductivity. As we all know, the thermal conductivity of inorganic nonmetallic materials is generally much lower than that of metal. Because inorganic nonmetallic materials are different from metals with metal bonds, there are very few free electrons. The thermal conductivity caused by free electrons in this material is extremely limited, and the lattice vibration is mainly deviated from the degree of resonance. The greater the degree of deviation from the resonance, the thermal conductivity is smaller. The degree of lattice vibration deviation increases with the difference in the molar mass of the constituent components, so the thermal conductivity of the element is the largest. (So the thermal conductivity of graphite is relatively large).</p><p><br /></p><p>China refractory bricks have a complex structure of crystals, the thermal radiation of the lattice is greater and the thermal conductivity is smaller, such as MgO, A12O3 and MgAl2O4 Such as MgO, A12O3 and MgAl2O4 are equiaxed, but the structure of MgAl2O4 is complex and the thermal conductivity is low. Non-coherent crystals, in the direction of dense particles along the crystal, thermal conductivity is larger. The quartz along the C axis has a dense accumulation of particles, and its thermal conductivity (13.6W/(m℃)) is about twice as high as that of the C axis. The layered structure of graphite, the thermal conductivity parallel to the direction of the level of about 4 times in the direction perpendicular to plane direction.</p><p><br /></p><p>If the crystal is defective, the formation of substitutional solid solution, because the rules of the crystal structure of the destruction caused by thermal scattering phenomenon, resulting in a decrease in thermal conductivity. Other crystal defects such as vacancies, dislocations and so on, also has a similar effect. Due to the thermal scattering of the grain boundary, the thermal conductivity of the polycrystalline material is lower than that of the single crystal. The refractory raw material of fine grain is lower than that of coarse grain. The material contains impurities, the thermal conductivity is lowered due to the scattering effect.</p><p><br /></p><p>When refractory bricks contain glass phase, due to the amorphous structure of the disorder, the probability of collision between atoms. So compared with the crystal, thermal conductivity is low. When the refractory brick contains pores, because the thermal conductivity of the gas is smaller than the solid, so with the increase in porosity, the thermal conductivity of the material decreases. This is the basic reason for the low thermal conductivity of porous materials.</p><p>Thermal Conductivity</p><p><br /></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhcApXFm-dllJ94M52bgKNE7kTs_BrMUnIoKACMgtOA3yn3cqjJ-mrD-yUjtV4eM69Il2vjqluK4ylGMJ6TWDx2uzpUUWpXhjmgynIPoZW-XEq0AKQRYylj6buTRHnrRRbTcjbO_PBb9Xw/s560/Thermal+Conductivity.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="560" data-original-width="560" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhcApXFm-dllJ94M52bgKNE7kTs_BrMUnIoKACMgtOA3yn3cqjJ-mrD-yUjtV4eM69Il2vjqluK4ylGMJ6TWDx2uzpUUWpXhjmgynIPoZW-XEq0AKQRYylj6buTRHnrRRbTcjbO_PBb9Xw/s320/Thermal+Conductivity.jpg" /></a></div><br /><p><br /></p><p><br /></p><p><br /></p><p>1-Silicon Carbide Brick;2-<i><b><a href="http://www.chinafirebrick.com/1Magnesia-Carbon-Brick.html" target="_blank">Magnesia Brick</a></b></i></p><p><br /></p><p>3-Silicon Carbide Brick(SiC70%);4-Corundum Brick</p><p><br /></p><p>5-Silicon Carbide Brick(SiC50%);6-Sintered Dolomite Brick</p><p><br /></p><p>7-Zirconia Brick;8-Chrome-Magnesite Brick</p><p><br /></p><p>9-Corundum(A12O390%);10-Sillimanite Brick</p><p><br /></p><p>11-Olive Brick;12-Chromite Brick</p><p><br /></p><p>13-Silica Bricks;14-Dense Clay Bricks</p><p><br /></p><p>15-Clay Brick</p><p><br /></p><p>Article Source:</p><p><b><a href="http://www.chinafirebrick.com/Company_News_128.html">http://www.chinafirebrick.com/Company_News_128.html</a></b></p><p>E-mail:sales1@chinafirebrick.com</p>cxrefractoryhttp://www.blogger.com/profile/05981944982062373022noreply@blogger.com0tag:blogger.com,1999:blog-1724404593062751375.post-81802090901468536102017-11-20T00:46:00.000-08:002017-11-20T00:46:01.024-08:00The trend of fused magnesia sand priceFrom news on foreign media that influenced by Chinese market, Fused magnesia sand price in European market is also higher and higher now, while the price is more than 1500USD/T now.<br />
<br />
The main reason is still because of lacking supply of <b><i><a href="http://www.yilongrefractory.com/ProductServlet?id=6" target="_blank">refractory raw material</a></i></b>. What was worse that there is no any evidence show that the price will be lower in nearly future.<br />
<br />
Winter is coming, and environment pollution will be heavier. Chinese government will carry out more and more environment protection policy, while more and more plant need to close which result in higher and higher price of fused magnesia sand.<br />
<br />
Most purchaser from all of the world calculate that fused magnesia sand price will be higher and higher in coming 2018.<br />
<br />
What is more, some foreign purchaser indicate that magnesia sand quality is not as good as before. This is also because there is not enough mineral supplying, which result in poor quality than before.<br />
<br />
So if you need <b><i><a href="http://www.yilongrefractory.com/AllProductServlet?id=1&number=20" target="_blank">refractory products</a></i></b>, please purchase as soon as possible. Time is money for you.<br />

Introduction<br />
<br />
The ladle nozzle well block connects the wearing refractory lining of the ladle bottom to the mechanism or ladle gate for the flow control. To the well block is asked a huge wearing resistance and moreover it has to protect the nozzle placed inside it. Our ladle nozzle well block is made with magnesia carbon material or alumina carbon material, which can be made according to customized.<br />
The ladle nozzle well block can be realized in any size and shape and strengthened with steel fibers to improve its mechanical resistance.<br />
<br />
The series of well blocks for nozzles are made from high-purity, high-density, high-strength materials. Based on different materials, they have corundum, magnesia carbon and alumina spinel carbon.<br />
Advantages<br />
<br />
They show the features of stable structure, excellent thermal shock resistance, good corrosion/erosion resistance and long service life.<br />
Application<br />
<br />
It is mainly used to fix upper nozzle in steelmaking.<br />
