Product Description:

Refractory Cement with High Refractories for Furnace Lining is made out of a naturally-occurring material known as bauxite. This material includes aluminum hydroxide, which is what gives the bricks such great warmth resistance. Refractory Cement also include kaolinitic clays, which are roasted to create an unique combination including mullite and also synthetic alumina. This is where the name “high alumina” stems from.

Q:Refractory insulation board, pressure plate, nano heat transfer plate, calcium silicate board and ceramic fiber board?
Sheng Yang series of ceramic fiber board is based on the traditional process of comprehensive upgrading of the excellent vacuum forming insulation materials, slag ball content of less than 3%, fiber distribution uniformity, internal and external strength consistent, size controllable.Ceramic fiber board is made by spraying superfine ceramic fiber through water washing, slag removal, fiber freezing and vacuum forming. The product has superior high temperature resistance, excellent rigidity and toughness.
Q:What is the difference between ceramic fiber board and nano ceramic fiber board?
The nano ceramic fiber board through the introduction of nanotechnology, the special production process, product performance has been greatly improved, high strength, low thermal conductivity, good heat insulation performance, energy saving effect is obvious, which improves the safety of the furnace, and in high temperature and high pressure conditions, can also play a good performance the product.
Q:Ceramic fiber plate and aluminium silicate plate are chosen as lining materials
Volume density is low: the density of the ceramic fiber lining is about 25% of the lining of the light heat insulation brick, about 10% of the lining of the light pouring material; adopting the fiber lining can greatly reduce the steel structure load of the furnace and prolong the service life of the furnace lining.
Q:What are the specifications of the ceramic fiber board?
Ceramic fiber board, also known as aluminum silicate or refractory fiber, including ceramic fiber blanket, ceramic fiber, ceramic fiber fireproof plate (plate).
Q:What are the sound-absorbing fiber boards?
Ordinary materials have sound-absorbing effect, just how much difference. And when it comes to sound-absorbing board, we are only sound-absorbing coefficient of more than 0.3 of the material known as sound-absorbing material.
Q:What are the differences between nano ceramic plate and ceramic fiber board?
Ceramic fiber board is a kind of ceramic fiber cotton produced by injection technology. It is made by continuous production and advanced technological production line.
Q:What are the uses of ceramic fiber boards?
The ceramic fiber board, also called aluminum silicate fiber board or refractory fiber board, is divided into five grades according to the temperature grade:Fire dragon type ceramic fiber board HLGX-164Fire dragon standard ceramic fiber board HLGX-264Fire dragon high purity ceramic fiber board HLGX-364The dragon of high alumina ceramic fiber board HLGX-464Fire dragon contains zirconium type ceramic fiber board HLGX-564
Q:What are the standards for ceramic fiber boards?
Ceramic fiber board is made of continuous production, water production line and advanced technology, ceramic fiber board produced with smooth surface, accurate size, good toughness, can be arbitrarily cut, good insulation effect and other performance characteristics.
Q:How much pressure can the ceramic fiber board withstand?
Ceramic fiber board divided by density, can be divided into ceramic fiber, ceramic fiber board density 250-260Kg/m fand; density, fand 300-350Kg/m;
Q:What method should be used to measure the thermal conductivity of fiberboard?
It is concluded that the test error of this method and device is about 2%. This filament ultra light aluminum silicate fiber product: the filament ultra light aluminum silicate product is by Shandong Zibo high quality burnt precious stone as raw material, passes through the smelting furnace, the rejection silk, blows the cotton, the auxiliary mold and so on to deliver the work procedure. Therefore, the thermal conductivity of fiberboard is chosen by heat flow meter method.
