The thermal shock resistance of a refractories, that is, the ability to measure the resistance of a refracting material to damages caused by temperature changes during heating and cooling, has a great influence on the lifetime of the refractories. The thermal damage of refractories is mainly related to the thermal stress generated during use.
Thermal stress is divided into two types: the first type of stress, caused by temperature gradients, ie, temperature stress; the second type of stress, ceramic fiber blankets are caused by volume expansion due to heterogeneity, linear thermal expansion, chemical reaction, polycrystalline transformation, etc. Or caused by shrinkage. Due to production inspections, system failures, etc., the production of Australian furnaces is interrupted or the production is not normal, and it is very easy to cause two types of thermal stress to damage the refractories.
Chemical corrosion occurs at the grain boundaries of the refractory crystals, that is, the slag enters the grain boundaries and chemically reacts with the grain boundary minerals to make the low-melting impurities in the grain boundary become thicker and longer, and the refractory mineral crystals are gradually surrounded and dissociated by the liquid phase. A type of erosion is severer than in the previous case. The larger the size of the refractory mineral crystal, the smaller the amount of impurities in the refractory material, the thinner the crystal film, the more reasonable the grain boundary chemical composition, the more resistant the grain boundary minerals to slag, and the slag resistance of the refractory material. The stronger it is. Improve the density, reduce the porosity, reduce the air permeability, the stronger the slag resistance of the refractories.
Ground Anchor / Earth Auger is a device designed to support structures, most commonly used in geotechnical and construction applications. Also known as earth auger, percussion driven Earth Anchor or mechanical anchor, it may be impact driven into the ground or run in spirally, depending on its design and intended force-resistance characteristics.
Earth augers are used in both temporary or permanent applications, including supporting retaining walls,guyed masts, and circus tents.garden or vineyard fence & .
Ground anchor mainly made of carbon steel/ thread steel ,with high dip galvanized surface treatment or powder coated treatment .
There are many colors of ground anchor ,such as black ,white ,red colors .
diameter of ground anchor pole :13-16 mm,length 30-60' or according to clients' request .
In addition to earth anchor,we also supply earth auger,Helical Ground Screw Anchor,Helical Ground Anchor,ground anchor pile,anchor bolt.
