Roller Hearth Furnaces


Industrial hearth rollers are a key component for industrial furnaces and are also known as hearth drums, hearth rollers or hearth conveyors. It usually consists of rollers, support bearings and transmission devices.

The main function of industrial furnace bottom rollers is to support and transport materials or fuel moving on the bottom of industrial furnaces. Through the rotation of the roller, the material can be smoothly transferred from the supply end to the discharge end. Rollers are usually made of high-temperature and wear-resistant materials to withstand the wear and tear caused by high temperatures and material friction.

Support bearings are used to support and position the rollers to ensure their normal rotation and movement. They usually adopt special bearing designs with high temperature and wear resistance to adapt to the high temperature and harsh working conditions of industrial furnaces.

The transmission device is used to drive the rotation of the roller. Common transmission methods include chain drive, gear drive and belt drive. These transmissions provide power through motors or other power sources to ensure that the rollers have sufficient rotational force and speed.

Industrial hearth rollers can have different structural designs based on specific applications and process requirements, such as linear hearth rollers, curved hearth rollers or annular hearth rollers, etc. In addition, industrial furnace bottom rollers usually need to have the characteristics of high temperature resistance, wear resistance and stable operation to ensure the transmission efficiency of furnace bottom materials and the normal operation of the furnace.

In addition to the basic functions and features mentioned above, industrial furnace hearth rollers also have some other important features and applications that need attention:

Adjustment and control: Industrial hearth rollers often have an adjustable design to control the material transfer speed according to process requirements. By adjusting the speed of the rollers or the spacing between the rollers, different conveying speeds and material layer thicknesses can be achieved to meet the needs of the process.

Cleaning and maintenance: To ensure the normal operation of industrial furnace hearth rollers, they need to be cleaned and maintained regularly. Because the material may adhere to the surface of the roller or accumulate between the rollers, reducing its transmission efficiency. Regular cleaning and maintenance can reduce breakdowns and extend service life.

Wear-resistant and high-temperature-resistant materials: Since industrial furnace bottom rollers operate in high-temperature environments and bear the friction and impact of materials, wear-resistant and high-temperature-resistant materials are required, such as refractory materials or alloy steel. This ensures the stability and service life of the rollers.

Usage environment and application: Industrial furnace bottom rollers are widely used in various high-temperature industrial furnaces, such as metallurgy, chemical industry, cement, glass and other industries. Specific applications include blast furnaces, converters, coke ovens, kilns and burner systems. According to different industrial furnace types and process requirements, the design and selection of furnace bottom rollers will vary.

To sum up, the industrial furnace bottom roller is a key device used in industrial furnaces. It has the function of adjusting and controlling the transmission speed. It needs to be cleaned and maintained. It uses wear-resistant and high-temperature-resistant materials and is widely used in material transportation and control of high-temperature industrial furnaces. . Specific design and selection should be considered based on different application requirements and process conditions.
