The main reason for the damage of high-temperature kiln lining is that the refractory material is eroded, washed, and worn, according to the use environment of each part of the kiln, the damage degree of the lining is not the same, some are only slightly damaged, and some parts are seriously worn. According to different lining parts, different fire-resistant repair materials are used, and targeted repair techniques and methods are selected to repair kiln lining quickly. Hubei furnace lining repair material manufacturers tell you

High temperature kiln local repair material selection of refractory raw materials, scientific ratio, after construction, can be quickly combined with the original lining, suitable for the repair of the damaged parts of the heating furnace, the material is mostly high aluminum, mullite, can also be used in iron and steel industry in a variety of high temperature industrial kiln, annealing furnace, baking furnace, sintering furnace, soaking furnace and other lining.

Refractory patching material can be made into powder, paste, in a long time to maintain high plasticity, hardening after a certain strength, after high temperature sintering, has good high temperature volume stability and other properties, can form a dense lining.

As one of the important types of amorphous refractories, refractory repair material has good high temperature performance and convenient construction, and is commonly used as refractory material for a variety of high temperature kilns. If the refractory material as the kiln lining is damaged and not repaired in time, it will directly affect the normal operation of the kiln and the safety of the operator, so it can be seen that the repair material of the kiln is very important.

The best high-temperature furnace refractory repair material can not be separated from the construction, repair technology and method because of different parts of the kiln damage, the construction is also different, the following is the common refractory repair technology:

1. High temperature lining is damaged

First of all, according to the damage to determine, such as simple damage, you can choose to spray or spray repair technology. Such as hot repair material, hot repair can be carried out by mechanical control repair equipment when the kiln is running. If the damage is more serious, the inner lining can be removed and suitable refractory materials can be used for construction and installation.

2. The insulation layer is damaged

Heat insulation layer is to avoid the heat loss of high-temperature kiln lining, usually choose insulation fiber material products with low thermal conductivity and lightweight heat insulation brick, heat insulation layer damaged, can use heat insulation spray paint to repair, increase the heat insulation effect of the kiln lining, to avoid affecting the heat cycle of the kiln.

3. The gap is damaged

Furnace cracks, air leakage and other sites are very common, such as blast furnace wall air leakage, hot air pipe cracks, you can use low-temperature perfusion material or refractory pressing material, the use of air compressor will be the refractory extrusion to the damage, after high temperature sintering, can quickly form a body.

High temperature furnace lining damage phenomenon is very common, as long as the use of refractory repair material and timely repair can avoid affecting the normal operation of the kiln.
