Q:What is the problem about splintering when the refractory brick is fired?
There are many bubbles inside the refractory brick, it is also possible that the brick itself is not up to the standard about volume density, then refractory brick fragmentates. There are many reasons, may be in the process of repression
Q:does furnace use refractory cement to make refractory bricks?
use refractory clay, refractory clay is made of refractory clinker clay mixing with cornstarch in a certain proportion, generally refractory cement refers to alumina cement, which is generally used in castable refractory, producing binder.
Q:does 90m high reinforced concrete chimney need firebrick?
The chimney need firebricks or casting fire or acid resisitant concrete after casting, one aim is to resist high temperature, then is to resist acid corrosion. there is a variety of models of the refractory brick , you can refer to the installation quota.
Q:The shape and size of general used refractory brick
240mm * 115mm * 53mm. and the width is 115mm, the shape and size of mechanism red brick is: 230mm * 114mm * 65mm, the outline dimension of special refractory brick is of 65mm thickness according to the national standard: Length is 230mm. That is: Length is 240mm. General type refractory brick's outline dimension is of 114mm width. That is, thickness is 53mm: 345*328*97
Q:What are the differences between sintered bricks and refractory bricks?
Sintered bricks belong to a type of refractory bricks.
Q:What material are used to burn firebrick?
Alkaline series of refractory bricks /, can be classified into five types. Refractory bricks are generally made from refractory clay (white clay) or other refractory materials. Refractory brick according to the composition of refractory material, that is, silicon aluminum refractory brick / carbon containing refractory brick / thermal insulation refractory brick/ zirconium containing refractory brick /
Q:should clay or refractory cement be used to lay refractory bricks?
structure strength of this brick lining is not good, apply some refractory mud, only use some virgin clay and corundum, many of the traditional approaches are very simple, mullite and carbon slurry, the specific products are selected according to the selected material and water glass or organic binder. binding agent can choose phosphate, silica and high alumina, clay is one part of the refractory clay, there are many kinds of refractory slurry according to the material, clay-based mud does use refractory cement and corrosion resistance is low
Q:How much is the silica powder in refractory bricks.
It's not easy to construct, also need to consider the technical and economic indexes, DH3, 1 kg silica powder replaces 1 ~ 3 kg cement, which is the reason why silicon powder was not used and spreaded in concrete in past, choose some silica power fume. In general, with the smoke escaping by special capture device for collecting and processing To determine the mixing method of silica powder, when mixing silica powder, you should find out the optimal dosage in order to obtain the best results, as the study, the content is 5% ~ 30%, H, the mixing of super high strength concrete, use same amount of silicon powder to replace equal cement to main same fluidity, Microsilica or Silica Fume, it is mainly according to the design requirements, and does not reduce the amount of cement, sand and stone to adjust the optimal dosage of water reducer, when deciding the best mixing amount of silica fume, the concrete is too sticky, most use naphthalene water reducing agent.
Q:How to repair the boiler?
What kind of boiler, the external wall or the furnace arch, the smoke wall, the material: High-alumina cement, refractory brick, refractory clay, knife brick
Q:air-cooled razheng times of magnesia-alumina spinel refractory bricks
The ingredients are magnesium, oxygen, and aluminum. the components of spinel refractory can be magnesia-alumina spinel with excessive aluminium oxide, or magnesia-alumina spinel with excessive magnesium oxide. excessive magnesium oxide and aluminium oxide can form magnesia-alumina spinel in above 1700 degrees.
