Product Name:Clay Bricks For Coke Oven
Product Description:
Clay brick is aluminum silicate refractory products with alumina content of 30~40%, and its mineral composition is mullite (3Al2O3·2SiO2)20%~50%, glass phase 25%~60%, quartzite and quartz (up to 30%).According to the content of Al2O3, ordinary clay bricks can be divided into: first class (>;40%), second class (>;35%), third class (>;30%).
The corresponding refractoriness is not less than 1700℃, 1670℃ and 1610℃;The softening temperature under load was between 1250 ℃ and 1450℃.Good thermal stability.It is generally used in the drying zone, pre-heating zone, decomposition zone and cooling machine of rotary kiln.In recent years, many countries have developed special clay bricks in order to improve the fire resistance temperature while maintaining alkali resistance.
What physical and chemical index does clay brick have
Clay brick is made of clay clinker as aggregate and refractory clay as binder.Its Al2O3 content is 30%~48%, suitable for heat exchange position, chain belt, decomposition zone, cooling zone, smoke chamber, grate cooler, etc., the brick wear-resisting performance is good, thermal conductivity is small, the price is cheap, only other brick price 1/4 ~ 1/2, but the fireproof degree and strength are lower.
The primary understanding factor in purchasing clay brick is the specification of clay brick.Specification of clay brick is divided into standard model, general model, special model and super special five kinds.
The following is a detailed introduction for you:
(1) Standard clay brick.Specification size of standard clay brick is 230mm×114mm×65mm.
(2)general clay brick.It is a general clay brick that has one of the following classification characteristics:
A. The mass is 2~8kg;
B. The thickness size is 55~75mm;
C. Not more than 4 measuring sticks;
D. Size to size ratio not greater than 4;
E. No concave Angle, arc, groove, hut, hole, hole and acute Angle ≤75°.
(3) special clay brick.Any one of the following classification characteristics is a special-shaped clay brick:
A. The mass is 2~15kg;
B. The thickness size is 45~95mm;
C. Size to size ratio is not greater than 6;
D. The total number of arcs and concave angles is not more than 2;
E. The total number of ditches and houses shall not be more than 4;
F. a & gt;An acute Angle of 50° and ≤75°.
G. Without holes.
4, special clay brick.One of the following classification characteristics is the general clay brick:
A. The mass is 1.5~30kg;
B. The thickness size is 35~135mm, and the length size of tubular brick is no more than 300mm;
C. Size to size ratio is not greater than 8;
D. The total number of arcs and concave angles is not more than 4;
E. The total number of ditches and houses shall not be more than 8;
F. An acute Angle of 30°~50°.
G. Not more than 1 hole or hole.
Where more than special characteristics for super special clay brick.
