Types and uses of castables

2024-05-29

Castable is a kind of material used to fill, block or protect some structures, which is widely used in construction, metallurgy, chemical industry and other fields. According to different usage scenarios and performance requirements, castables can be divided into many types.

types of 1. castable:

1. Refractory castable: mainly used for the lining of high temperature equipment such as blast furnace and hot blast stove in metallurgical industry, with good high temperature resistance.
2. Expanded perlite castable: expanded perlite as aggregate, low density, light weight, used for sound insulation, heat preservation and other occasions.
3. Ceramic castable: has excellent wear resistance, corrosion resistance, suitable for chemical, electric power and other industries of pipes, containers, etc.
4. wear-resistant castable: containing wear-resistant additives, mainly used for high wear environment of the ground, pipelines, etc.
5. High temperature resistant castable: can withstand high temperature environment, suitable for furnace, flue and other high temperature equipment lining.
6. thermal insulation castable: has good thermal insulation performance, commonly used in construction, petroleum, chemical and other fields of thermal insulation engineering.

the use of 2. castable:

1. Construction field: used for insulation and fire prevention works of walls, roofs and other parts.
2. Metallurgical industry: lining of blast furnace, converter and other equipment to improve the service life of the equipment.
3. Chemical industry: anti-corrosion and wear-resistant lining of reaction kettle, pipeline, storage tank and other equipment.
4. Power industry: flue, boiler and other high temperature equipment lining, improve the thermal efficiency and service life of the equipment.
5. Petroleum industry: the lining of storage tanks, pipelines and other equipment to prevent medium corrosion.
6. Mining field: wear-resistant lining of mining equipment to improve the processing capacity of equipment.
7. Other fields: It can also be used in some specific parts of shipbuilding, automobile, aerospace and other industries.

In short, castables are widely used in various industries because of their excellent physical and chemical properties. Different types of castables can be selected according to the specific use environment and requirements to meet different engineering needs. In practical application, the construction and operation should be carried out according to the specific situation to ensure that the castable plays its due performance. In the future, with the progress of science and technology and the development of the industry, the types and uses of castables will be further expanded.
