Q:What is the apparent porosity of high alumina brick?
Total porosity is porosity refers to the total volume of sample porosity in the percentage of total volume of samples. Apparent porosity refers to the percentage of the total volume of openings, pores, and total specimens in the sample.
Q:Use of high alumina refractory bricks?
High alumina brick refractory than clay refractory bricks and brick refractory degree are higher, up to 1750~1790 DEG C, which belongs to high-grade refractory materials.
Q:What is the difference between fireclay bricks and high alumina refractory bricks?
First of all, there is a difference in the material, one is clay, and one is high aluminum.Also known as clay brick brick, is a man-made small bulk building, clay brick clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting, solid and hollow.
Q:What is the price of the latest thermal insulation material?
There are many kinds of insulation materials, and the price will fluctuate with the market. Small quantities of inquiry or procurement, then go directly to the local thermal insulation market, a wide variety of prices are basically the market price.
Q:What's the difference between a well type annealing furnace and a box type annealing furnace?
1. The shell of the furnace is welded by section steel and steel plate. 2, the furnace cover support adopts steel and guide rail combination mobile type. 3. The heating element is made of high resistance alloy 0Cr25Al5 produced by Beijing Shougang Group and arranged on the furnace side. 4, because the bottom bearing adopts high aluminum bricks, the circle center of the furnace set small, inside and outside heating. 5 、 furnace cover adopts hydraulic lifting, motor control, automatic walking. 6 、 temperature control system adopts PID SCR control, high accuracy.
Q:What kind of material is the general metal case?
Generally speaking, the outer surface of the case is usually made of a steel plate of more than 1 millimeters. The thickness and the material of the steel plate are directly related to the rigidity of the case, as well as the capability of sound insulation and anti electromagnetic radiation. The regular manufacturers of the chassis plate thickness not less than 1.3mm, but there are also some small manufacturers with a thickness of only about 1mm steel, we do not need the ruler to the amount, as long as you put him up, the more weight in the same volume of the chassis is better, in addition, we can also use the finger bomb case shell. If you can hear the crisp percussion sound proof of the casing plate is thin and brittle, if you hear is relatively dull and heavy sound that the chassis material must be good, good general steel plate coated with a layer of thin zinc (bright part), so it can withstand high strength, impact resistance, hardness high elasticity. The frame parts of the chassis are made of high quality materials with high hardness. They are bent into angle shapes or strip shapes. We can shake the chassis frame of the case by hand. Good chassis should be relatively stable, and inferior chassis light is easy to shake. When choosing, we should also pay attention to the outer edge of the case and the edge of the inner bracket. Whether the incision is smooth or not, a good case will not appear in the case of rough edges, sharp edges, burrs and so on. While the poor case appears above phenomenon, often appear when installing the blood splattered". Generally speaking, the chassis must go through the corresponding grinding process before leaving the factory. The edge of the flat plate some burr, edges and corners are rounded, the corresponding fold some corner. When you install such a case, you don't worry about cuts, and some rough, poorly built cabinets tend to scratch your hands.
Q:How to reduce porosity of high alumina brick
In order to reduce the porosity of high alumina brick, the corresponding measures should be taken from the selection of raw materials, batching, mixing, molding and firing.The water absorption rate of the first grade high alumina bauxite clinker should be less than 5%, and the water absorption rate of two grade high alumina material should be less than 7%. Fine grinding of soft clay and bauxite clinker with less than 4% water content. Mixed fine milling ingredients with this, can reduce the porosity of bricks.
Q:Are there any differences between insulating bricks and refractory bricks?
As the name suggests, the main role of insulating brick is used to preserve heat and reduce the loss of heat. Such as: Molai S; and the firebrick is mainly used to withstand flame burn. Bricks usually do not contact fire directly, while refractory bricks usually contact the flame directly.
Q:What is the standard classification of high alumina bricks or high alumina bricks?
High alumina brick is a kind of refractory material in refractory brick products. It is made of refractory clay or other refractory material. It belongs to the product of Si Al System
Q:Aluminum content 38. silicon content 55 What refractory bricks?
Hello Only on behalf of the Zhengzhou colt as refractory product index your answer to this question is not entirely separate from the chemical index of aluminum content, silicon content and judgment, personally think that three types of refractory bricks may respectively is: Two: semisilica brick high alumina brick
