How to choose the one-step firing process

How to choose the one-step firing process?

If you are not professional and confused about the brick firing processing, Brictec would like to offer some help. Hope it really can help your business.

a).material placitily index must be available.for exmple: the natural water content of the raw materials is less than 16%, the drying shrinkage is less than 3%, the drying sensitivity coefficient is less than 0.8. To stack the wet brick on the kiln cart or stack in kiln need to stack 9~15 layers to reach the production requirements, generally it is more suited to the shale and gangue materials, not suitable for High-volume fly ash material.

b) the wet green body strength/ cm², or several under layers will fracture due to low strength. Wet blank must be semi-hard plastic or hard plastic extrusion, extrusion pressure must be more than 2.5MPa, the chamber vacuum is more than 80%, the raw material particles is equipped to be reasonable. is higher. to reach 2.5 ~ 2.8kg

c) product shape and structure is not complex. The product size is not too large, no more corners , the pore wall is not too thin, the hole shape can not be too complex ,which appropriate one step firing process.

How to differentiate between the one-step firing process and two-steps firing process

There is difference when in the process of brick firing which has effects on the finished product. 

Brictec would like to offer some tips as follows:

The basic process of fired brick can be divided into: material processing, aging, extruding, stacking, drying, stacking in kiln and firing. The difference between the one-step firing process and two-steps firing process lies in Stacking process, drying process, stacking in kiln and firing process.

Two-steps firing process

Wet brick—stacking –natural drying—stacking in kiln — Hoffmann kiln

Wet brick—drying cart—dryer—kiln cart---tunnel kiln
