Ordinary clay bricks are made of soft clay with strong plasticity and great dispersibility and a part of clay clinker. Generally divided into clay clinker and aged soil clinker brick. Their main high temperature performance refractoriness is higher than 1750 ℃ for the special grade, 1730-1750 ℃ for the first grade, 1670-1730 ℃ for the second grade, and 1580-1670 ℃ for the third grade. Multi-clinker clay bricks refer to products containing more than 80% clinker and less than 20% combined clay. Since most of the multi-clinker clay bricks are in a barren state, they are not easily deformed during the manufacturing process, which can ensure the external dimensions of the bricks, so that the fired products have ideal bulk density, mechanical strength, thermal shock resistance and high of refractoriness. All-raw clay bricks, also known as clinker-free clay bricks, are made of hard clay or pyrophyllite with low plasticity, weak dispersibility and little shrinkage. Since this kind of raw material has less inherent moisture, it can still maintain the original particle composition although it is given a certain amount of added moisture after pulverization. produce shrinkage.

Special-shaped clay bricks. Those with one of the following classification characteristics are special-shaped clay bricks:
A. The mass is 2-15kg
B. Thickness dimension is 45-95mm
C. Size-to-size ratio 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 is not more than 4
F. An acute angle >50° and ≤75°.
G. Without holes and holes.
Characteristics of clay refractory bricks
1. Chemical composition: The main components determine the quality and characteristics of the refractory.
2. Bulk density: The unit volume weight and the high density indicate that the density is good, the strength may be high, but the thermal conductivity may be large.
3. Apparent porosity: There are no specific requirements, but as a manufacturer, it is necessary to strictly control the apparent porosity.
4. Load softening temperature: also called high temperature load starting deformation temperature, this parameter is very important and marks the resistance of the material.
5. Thermal shock resistance: the ability to resist rapid temperature changes without being damaged.
6. Compressive strength: the ability to withstand (normal temperature) pressure.
7. Flexural strength: the ability to withstand shear pressure.
8. Linear change rate: also called reburning line change or residual line change, which refers to the change of volume expansion and contraction in the same temperature change each time. If each expansion and contraction is the same, we define such a linear change rate as 0.
Qualified blast furnace clay bricks are the phosphoric acid impregnated products after drying treatment, vacuum phosphoric acid impregnation and secondary low temperature firing, which are used to build the upper lining of the blast furnace body.
