Understand the Refractory Fire Clay Mortar

Clay clinker is an important component of clay refractory mortar, which accounts for about 75% to 80%. Raw clay is a binding agent. It is added to increase the plasticity of clay fire clay and reduce air permeability and water loss rate. The added amount is about 20%-25%.

As a joint material, Kerui clay refractory motar can adjust the dimensional deviation of the refractory bricks. This maintains gas regulation and load balance inside the kiln. Masonry can also form a tight whole to resist damage from external forces and the intrusion of chemical gases and molten liquids.

Importance of Choosing High-quality Fire Clay Mortar

Keep the Stability of Your Kiln

A kiln’s stability is paramount to its functionality and longevity. The fire clay refractory mortar used in its construction serves as the binding agent for the refractory bricks, creating a cohesive and resilient structure. High-quality fire clay mortar ensures a robust bond between the bricks, which prevents gaps or weak points that could compromise the kiln’s structural integrity.

Improve the Efficiency of Kiln

Efficiency in kiln operations is closely tied to the ability to contain and control heat. The use of high-quality fire clay mortar plays a pivotal role in creating tight seals between refractory bricks. These seals minimize heat loss, which ensures that the kiln operates at optimal temperatures. The result is improved energy efficiency and reduced fuel consumption and enhanced overall performance.

Choosing Conditions of Kerui Clay Mortar

  1. Masonry joints are generally the weak link of the gas, and in most cases are damaged before the gas, so their quality has a close relationship with the overall life of the gas;
  2. The refractory degree and chemical composition of clay refractory mortar are similar to other refractory materials in masonry;
  3. The particles of clay refractory mortar are compatible with the brick joints, and the large particles do not exceed one-third to one-half of the brick joints;
  4. The expansion and contraction rates are suitable for the refractory bricks to be laid;
  5. Check mechanical strength and good air tightness before masonry.
