Brown fused alumina, alumina porcelain, high-frequency porcelain, what material is used for grinding the? And other?

Brown fused <a href="https://www.facebook.com/pages/White-fused-alumina/151832528325664">White fused alumina</a>is mainly used in: 1: abrasives 2:3: refractory sandblasting 4: emery wear-resisting floor 5: precision casting mould making.<br />Dongguan  widely suggested is a dedicated to promoting new environmental  protection polishing equipment, grinding materials, additives, such as  hundreds of kinds of product research and development of high and new  technology enterprise, the high frequency porcelain products used in  various types of high-<a href="http://www.hnhxgk.com/key-sic-refractory-240/">Sic Refractory</a>insulator,  porcelain dial section switch axis, porcelain bushing, resistance  matrix and containment shell electron yuan, device, it has high thermal  insulation, good chemical stability and good compressive strength  etc.Grinding stone is indispensable in the process of grinding and  polishing metal processing material. With centrifugal, vibration, eddy  current, rotary, box-type grinding machine. To metal burr, flash, scale,  rusty spot, inverted, rough grind cutting edges and corners

Fused silica refractory

Fused silica refractories and technical equipment for its manufacturing  process compared to other refractory industry is relatively simple, and  compare its performance and relative location, and the cost is low, and  it could get a lot of applications, since we started late in our  manufacturing processes and equipment Western countries is less than  perfect with industry manufacturers, compared with foreign refractory  Sic Refractoryindicators and the results of not less than the level of  similar products, but our products due to processing equipment is not  complete, in appearance, there is a large gap with foreign products,  select performance processing equipment, improve the appearance of the  product, and should be not only external beauty but also inner beauty so  that product quality to the next level.

Types of high alumina refractories

Ordinary Alumina Oxide bricks: the main mineral composition of alumina bricks mullite, corundum and glass phase. With products in the aluminum oxide content.Increases, mullite and corundum phases increases the number, a corresponding reduction in the glass phase, products increase as refractoriness and high temperature performance
Modified alumina bricks: including high load soft high alumina bricks, high alumina bricks micro-expansion, low creep high alumina bricks, high alumina brick phosphate-binding.

How much is the density of corundum?

Density is divided into two kinds of Brown Corundum is called, one corundum bulk density, particle density, the second is Brown Corundums.

Bulk density of 1.53 ~ 1.99g/cm3, abrasives and abrasive particle bulk density, particle size composition, species, particle shape and other factors are related, in general, coarse-grained than fine-grained abrasive abrasive bulk density, particle size of the abrasive mix Bulk density is greater than a single particle density.

Particle density of 3.95 ~ 4.0/cm3, the silicon carbide abrasive particle density refers to the unit volume (excluding the volume of open porosity) contained within the abrasive mass
