K23 Mullite Refractory Bricks Introduction

K23 mullite refractory bricks are usually used to withstand high-temperature environments, and their melting point is generally between 1600°C and 1800°C.

Features of K23 mullite refractory brick insulation brick

1. Good thermal insulation performance: K23 thermal insulation brick has a low thermal conductivity, which can effectively reduce heat conduction and provide an excellent thermal insulation effect.
2. Lightweight: K23 insulation bricks have relatively low density and are lightweight, making them easy to carry and install.
3. High-temperature resistance: K23 mullite refractory bricks can withstand higher temperatures, usually up to 1350°C to 1430°C.
4. Chemical corrosion resistance: K23 mullite refractory bricks has good corrosion resistance to some acids, alkalis, and other chemical media.
5. Ease of processing: K23 mullite insulation bricks can be easily cut, drilled, and installed to meet application requirements of different shapes and sizes.

The raw material composition of mullite insulation brick

• High-purity mullite: mullite is an ore mineral with a high melting point and good refractory properties, and its main components are silicon dioxide (سی او₂) and aluminum trioxide (ال₂اے₃). High-purity mullite is one of the main components of K23 insulation bricks.
• Binder: In order to make the K23 insulation brick have a certain structural strength and stability, it is usually necessary to add a certain proportion of binder. Common binders include high-temperature refractory cement, high-temperature refractory glue, وغیرہ.
• Other additives: In order to further improve the performance and processing technology of K23 insulation bricks, sometimes a small number of other substances are added, such as anti-corrosion agents, modifiers, وغیرہ.

Classification of mullite insulation bricks

The main classification is based on the JM series: JM23, JM26, JM28, JM30, JM32, and K23, k26, k28, and other models. Rongsheng refractory suppliers can customize mullite insulation bricks according to different use environments.

Which industrial furnaces are K23 mullite insulation bricks used for?

Mullite insulation bricks are mainly used in blast furnace body and bottom, hot blast stove top, glass melting furnace regenerator, petroleum cracking system lining, ceramic kiln, وغیرہ. At present, it has been widely used in the lining of shuttle kilns, roller kilns, گلاس, and petrochemical kilns.
