Refractory plastic refractory has obvious advantages in repairing converter lining, mainly in the following aspects:

I. Construction convenience

Fire-resistant plastic refractory has good plasticity, and it can be formed manually or mechanically with simple tools without complicated equipment during construction. This material can be directly used in tamping construction, which can quickly fill the damaged parts of furnace lining, with fast construction speed and high efficiency.

II. Excellent high-temperature performance

Fire-resistant plastic refractory performs well in high temperature environment, and its strength increases with the increase of temperature. It can withstand high temperature and resist slag erosion, and has high fire resistance and corrosion resistance. In addition, the fire-resistant plastic refractory also has good thermal shock resistance, which can keep its performance unchanged under drastic temperature changes.

III. Wear resistance and mechanical strength

Fire-resistant plastic refractory has excellent wear resistance and mechanical strength, and is not easy to crack or break. This material can effectively resist mechanical impact and maintain the integrity of furnace lining during use.

IV. Rapid curing and repair

Fire-resistant plastic refractory can be cured quickly after construction, and the cured material is well combined with the original furnace lining, which has good adhesiveness. This enables the repaired lining to be quickly restored to use and reduces downtime.

V. Integrity and tightness

The fire-resistant plastic refractory is integrated after construction, which reduces the existence of brick joints, thus reducing the risk of heat loss and slag infiltration. This material has good sealing performance, and can effectively prevent the corrosion of high-temperature gas and slag.

VI. Economy and sustainability

The fire-resistant plastic refractory has a long service life and can significantly reduce the maintenance cost. In addition, its characteristics of convenient construction and rapid repair also enable enterprises to save time and resources in the process of use.

VII. Self-healing function

Some fire-resistant plastic refractory also has the function of self-repairing, which can prevent the cracks from expanding further through the toughness of self-repairing agent when cracks appear. This feature further improves the service life and reliability of the furnace lining.

VIII. Summary

Refractory plastic refractory has many advantages in repairing converter lining, such as convenient construction, excellent high-temperature performance, strong wear resistance, high mechanical strength, rapid curing, good integrity, strong sealing and high economy. These characteristics make it an ideal material for repairing converter lining, which can effectively prolong the service life of furnace lining, reduce maintenance cost and improve production efficiency.
