High alumina cement: benefits for industry

Introduction

High alumina cement (HAC) - is a specialized construction material with a high content of aluminum oxide (Al₂O₃), which provides it with exceptional heat resistance and strength. Due to its unique properties, it is widely used in metallurgy, construction and other industries. In this article, we will discuss the key advantages of high alumina cement and its practical applications.

1. basic properties of high alumina cement

High alumina cement differs from ordinary Portland cement in composition and characteristics:

• High temperature resistance - withstands temperatures up to 1600°CThis makes it indispensable in furnaces, boilers and other high-temperature applications.

• Rapid curing - gains strength already after 24 hoursreducing construction time.

• Resistance to aggressive media - not subject to corrosion by acids, alkalis and sulphates.

• High compressive strength - outperforms traditional cements, which is important for load-bearing structures.

These properties make alumina cement the best choice for heavy industrial applications.

2. Applications in the metallurgical industry

2.1 Lining of metallurgical furnaces

Kerui Refractory's VGC is widely used for lining construction and repair:

• Blast furnaces (temperatures up to 1500°C)

• Steel converters

• Induction and arc furnaces

• Buckets for molten metal

Technical advantage: formation of a tight ceramic bond when heated, ensuring a long service life.

2.2 Repair compounds for metallurgical equipment

• Hot repair of chutes and chutes

• Rebuilding the lining without stopping the furnace

• Crack and damage sealing

3. use in the refractory industry

3.1 Manufacture of refractory products

• Molding mixtures for refractory bricks

• Binder for heat resistant concrete

• Manufacture of crucibles and casting molds

3.2 Special solutions

• Coke oven battery lining (CO resistance)

• Refractory coatings for pipelines

• Protective structures in high temperature areas
