Advantages of Silica Bricks and Zero-Expansion Silica Bricks
Application of Silica Bricks and Zero-Expansion Silica Bricks in Glass Kilns, refer to acidic silica products with SiO2 content greater than 93%. The properties of silica bricks include chemical mineral composition, true density, bulk density, refractoriness, load softening temperature, high-temperature volume stability, thermal shock resistance slag resistance, etc. Refractory Bricks WikiTags Silica Bricks, Zero-Expansion Silica Bricks.
What are the Advantages of Fused Silica Bricks for the Hot Repair of Coke Ovens? During the long-term use of coke ovens, the furnace body will inevitably gradually aging due to high temperature, mechanical force, and physical and chemical reactions. The generation of melt holes in the coke oven carbonization chamber is the main sign of coke oven aging. For repairing coke ovens, fused silica bricks or ordinary silica bricks are generally used.
Similar to most sintered refractory bricks, silicon bricks are created by semi-dry methods in addition to being fired in tunnel kilns. It is what you need to know for the boost in its scrap charge due to cracks in the manufacturing process. Next, I will briefly expose the cause of si Let’s take a search at the types in order to result in packet cracks! Types and factors of silicon brick fracturesThe cracks of silica brick products can end up being divided into surface splits and internal cracks, typically the latter can also be called spalling. Surface cracks are broken down into transverse cracks, longitudinal cracks, and network splits.
Silica bricks are produced simply by using a semi-dry substance press molding method to be able to prepare compact bodies. The particular cracks produced along typically the direction of the packet pressing are transverse splits, and the cracks created perpendicular to the pushing direction in the bricks happen to be vertical cracks. It will be composed of several breaks, that are distributed like a new spider web, that will be, a net-like crack. Typically, for a standard silica brick, the pressing path of the green human body is usually the width direction. The molding method of silica brick goods is essentially a procedure of making the contaminants in the blank thick and expelling air in order to create a compact physique. After the brick is usually pressed and formed, this has the advantages involving high density, high strength, smaller drying shrinkage and shooting shrinkage, and easy control over product size.
However, once the press molding process is definitely improperly controlled, layered breaks perpendicular to the pushing direction will be shaped during the pressing procedure. Therefore, the layered fractures inside the silicon packet, or simply laminar splits, will also be longitudinal cracks. Huge spalling can be recognized when the brick is just formed or following the brick has dried out. Yet, the tiny spalls inside the bricks can simply be clearly detected right after firing if the silicon stones continue to expand along with the action of cold weather stress during the shooting process. Silicon bricks made up of crack defects, especially spalling, are susceptible to break, which can not end up being used and reduces typically the yield of silicon large rock products.
Kinds of Silica Bricks Shapes Customized Size Available
Silica brick is featured with strong acid slag erosion resistance, high refractoriness under load, and volume stability at high temperatures. It is mainly used in the coke oven, open hearth, glass kiln, ceramic kiln, blast furnace, etc. The silica bricks have the ability to keep volume stable at high temperatures for a long time. If you are a silica buyer and want to buy silica bricks for your glass kiln, coke oven, or hot blast stove, please Email Rongsheng Kiln Refractory Company to get the cheap silica bricks! The silica brick is made of tridymite, cristobalite, silica, and glass phase, choosing natural silica as the main raw material, adding the appropriate amount of mineralized, and pouring into some binding agent. Silica bricks are made of the original rock of silica. The larger the amount of the SiO2 content of silica raw materials, the higher the refractoriness. Zhengzhou Rongsheng Kiln Refractory Co., Ltd. is committed to the production of high quality, the use of safe, stable, and reliable refractory bricks products, for the majority of customers to provide quality, comprehensive service, sincerely welcome customers to come to consult, procurement of refractory material, we will serve you wholeheartedly.
