How to choose refractory cement? A guide from Kerui Refractory

Refractory cement - is an indispensable material in industry, metallurgy, furnace construction and other high-temperature environments. The right choice of cement determines the durability and reliability of the construction. In this article, experts Kerui Refractory will tell you what parameters to pay attention to when choosing refractory cement, as well as present the best solutions from the company.

1. basic characteristics of refractory cement

1.1 Al₂O₃ (aluminum oxide) content

One of the key quality indicators of refractory cement is the aluminum oxide content (Al₂O₃). The higher this parameter, the better the heat resistance and strength of the material.

• Low content (40%-60%) -. used in metallurgy and furnace (1200℃-1500℃).
• Average content (60%-75%) - used under extreme conditions (1500°C-1700°C).
• High content (≥75%) - used in extreme conditions (over 1700°C).

Kerui Refractory offers cements with different Al₂O₃ contents, which allows to choose the best option for any application.

1.2 Temperature resistance

Refractory cement must be able to withstand not only high temperatures but also temperature fluctuations. Depending on the area of application, it is selected:

• Conventional refractory cement (up to 1500°C) - for household stoves and chimneys.

• High alumina cement (1500°C-1700°C) - for industrial furnaces.

• Ultra-high temperature cement (over 1700°C) - for metallurgical and ceramic production.

1.3 Strength and adhesion

A good refractory cement should possess:

• high initial and final strength;

• excellent adhesion to metal, brick and other materials;

• resistance to cracking.

2. Which refractory cement to choose?

2.1 For domestic use (stoves, fireplaces, chimneys)

If you need fire-resistant cement for home use, Al₂O₃ 40-60% is the right choice. They provide reliable protection at temperatures up to 1500°C.

2.2 For industrial furnaces and boilers

The metallurgy, cement and glass industries require more resistant materials.

2.3 For extreme conditions (metallurgy, ceramics)

If you need material for temperatures above 1700°C, choose specialized compounds.
