Clay bricks are the oldest, the most widely used refractory materials, to produce the raw material is clay mineral clay brick,
natural refractory clay generally can be divided into hard clay and soft clay, the refractory material in the manufacturing process,
the former is the most used after calcining clinker;The latter after adding water, plasticity is good, easy to sintering, used as a binder.
Refractory clay, clay clinker for orthopaedic binder made of Al2O3 content is 30-48% of refractory products.Clay bricks are the oldest, the most widely used refractory.In the 70 s China clay brick production accounts
for about 65% of the total output of refractory, countries such as America, Britain, Japan accounted for about 40 ~ 50%.
Raw material is clay mineral to make clay brick.Natural fire clay in general can be divided into hard clay and soft clay.
In refractory material in the manufacturing process, the former most used after calcining clinker;The latter after adding water,
plasticity is good, easy to sintering, used as a binder.China's shandong province and other places the chamotte (hard) and
suzhou clay (soft) is a famous high quality refractory clay.Clay minerals are mainly kaolinite (2 sio2, Al2O3 · 2 h2o),
dickite (composition and kaolinite and same, but different lattice constant), montmorillonite (4 sio2, Al2O3 · 6 h2o) and mica mineral.
- Q:What is the role of refractory brick, whether is there any books to introduce refractory bricks
- Fire resistant, flame retardant, used for building stove and firewall,
- Q:What is the refractory temperature of refractory bricks?
- First look at the used parts of refractory brick, anti stripping performance, these are the most basic performance factors, the refractory temperature of high alumina brick is 1770 -1790 degree, the refractory temperature of clay brick is 1380-1570 DEG C, record the anti acid corrosion data of refractory bricks, the compressive strength of refractory bricks, at the same time, you should analyze each part of the furnace pH index and sintering temperature of working. When purchasing refractory bricks, you need to pay attention to many factors, high temperature creep property, softening temperature under a fixed load, 6548, volume stability at high temperature. Because the production of the product is affected by the weather and fuel energy, etc.. 186, select the suitable refractory bricks
- Q:Why do some people say that clay brick insulation effect is good, and some people say that bad, in the end what is right?
- Now is the best thermal insulation hollow powder briquette, because it is hollow, blocking the heat transfer, plus foam insulation on the outside, good insulation effect,
- Q:How to test the various components of the refractory brick?
- If you want to know the chemical?compound components, you can do the analysis of meteorological chromatography, and then testing, if you just want to detect contents of elements, you can do a XRF, but you should smash, grind and homogenize the refractory bricks. The specific operation process is not convenient to describe in detail, that is, X ray diffraction, through X ray fluorescence analysis, you can know that the elements and contents contained in it, if you want to understand its internal structure, you can also do a XRD
- Q:What kind of coal should be used to burn refractory brick? and how many calories smoke is suitable?
- Coal briquette's effect is also good
- Q:MU10 what are the non clay solid bricks?
- Clay solid brick with clay and is needed by adding admixture as raw materials, solid bricks by water mixing, molding, high temperature calcination made, mainly used for masonry bearing and non bearing wall, wall materials is a kind of widely used.
- Q:Why is the brick instead of solid clay brick
- Shale has the characteristics of high temperature resistant, is fire gangwa, pottery, porcelain power the best materials, especially shale burning system with shale brick is a new type of environmentally friendly building materials, has become the main building material to substitute for clay brick, high economic and social benefits, the market prospect is broad, is the best raw material for production of high hollow brick wall the quality of the.
- Q:How to count the number of loading refractory bricks?
- Use one meter by one meter wooden raft-towing: use one meter raft-towing to count: Known your brick is T-3 standard bricks, each four layers lies down 15 and sidewards is 4 =64; according to 3.4kg, 47 clay bricks can hold 10 to 12 layers. According to the upper limit, each raft-towing can hold 2.3 tons
- 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:What are the weak points of clay bricks?
- Clay bricks are clay products with Al2O3 content of 30%~40% aluminum silicate material. Clay brick is made of 50% soft clay and 50% hard clay clinker, according to the requirements of a certain particle size. After molding and drying, the clay brick is burnt at high temperature 1300~1400 degrees celsius. The mineral composition of clay brick is mainly kaolinite (Al2O3, 2SiO2, 2H2O) and 6%~7% impurities (potassium, sodium, calcium, titanium, iron oxides). The sintering process of clay brick is mainly the process of the continuous dehydration of kaolinite and the formation of crystallization of mullite (3Al2O3. 2SiO2).
