Patching techniques and methods of Refractory for patching

Refractory for patching manufacturers tell you that the main reason for the damage to the lining of high-temperature kilns is that the refractory materials are eroded, washed, and worn. Some parts are severely worn. For different lining parts, different refractory repair materials are used, and targeted repair techniques and methods are selected to quickly repair the kiln lining.

High-quality refractory raw materials are selected as the local repair materials for high-temperature furnaces, with scientific formula ratios. After construction, they can be quickly combined with the original lining. The manufacturer of Refractory for patching tells you that it is suitable for repairing damaged parts of heating furnaces, and the material is mostly high aluminum It can also be used in a variety of high-temperature industrial kilns, annealing furnaces, roasting furnaces, sintering furnaces, soaking furnaces and other linings in the iron and steelmaking industry.
The refractory repair material can be made into powder or paste, which can maintain high plasticity for a long time, and has a certain strength after hardening. After high temperature sintering, it has good high temperature volume stability and other properties, and can form a dense Lined.
Refractory patching material is one of the important categories of unshaped refractory materials. Refractory for patching manufacturers tell you that it has good high temperature performance and convenient construction. It is a common refractory material for many high temperature kilns. If the refractory material is used as the lining of the kiln and is not repaired in time, it will directly affect the normal operation of the kiln and the safety of the operators. It can be seen how important the repairing material of the kiln is.
High-quality high-temperature kiln refractory repair materials are inseparable from the cooperation of construction. The repairing technology and method are different due to the different damaged parts of the kiln, and the construction is also different. The following are common repairing technologies for refractory repair materials:
1. High temperature furnace lining is damaged
First of all, it is judged according to the damage situation, such as simple damage, spraying or gunning technology can be used. The manufacturer of Refractory for patching tells you that if the hot patching material is used, the mechanically controlled patching equipment can be used for hot patching when the kiln is running. If the damage is serious, the inner lining can be removed, and suitable refractory materials can be selected for construction and installation.
2, the insulation layer is damaged
The thermal insulation layer is the inner lining to avoid the heat loss of the high temperature kiln. Usually, the thermal insulation fiber material products and lightweight thermal insulation bricks with low thermal conductivity are selected. After the thermal insulation layer is damaged, it can be repaired with thermal insulation spray paint to increase the The thermal insulation effect of the kiln lining avoids affecting the thermal cycle of the kiln.
3, the gap is damaged
Cracks in kiln gaps and air leakage are very common. For example, air leakage occurs in the blast furnace wall and cracks in the hot air pipeline. Low-temperature pouring material or refractory pressing material can be used, and the refractory material can be squeezed by air compressor to the damaged part. After high temperature sintering, it can be quickly formed into one.
Refractory for patching manufacturers tell you that it is very common for the lining of high-temperature kilns to be damaged. As long as high-quality refractory repair materials are used and repaired in time, it can avoid affecting the normal operation of the kiln.
