According to the transmission form

There are three types: collective transmission, individual transmission and traveling. The first two types are widely used, especially the individual transmission mode develops rapidly, and the traveling roller table is rarely used. Collective transmission is mainly used in areas with harsh working conditions, heavy workload and high ambient temperature. Usually, it is used to transport short and thick rolled pieces, such as roller table in front of furnace and behind furnace, roller table before and after rolling mill, etc. This transmission mode complicates the roller table, but the roller table uses less electrical equipment, consumes less energy, is convenient for several kinds of ventilation, is easier to manufacture and has less investment. The single drive roller table is mainly used in areas with light workload, slender rolled pieces and low temperature, such as finishing areas. The main advantages of the roller table with independent drive are small flywheel torque, easy starting and braking, rapid roll change independently, convenient maintenance without affecting production, easy adjustment of roller height, simple structure, light weight, easy processing and easy standardization. Compared with the collective drive, the roller table has higher cost and higher inertia when running.It is not easy to stop, so it is not easy to choose the rolled piece that requires accurate stop.

According to the structural characteristics

It can be divided into hollow roller table, solid roller table, circular roller table, patterned roller table and conical roller table, etc., which can be selected according to working conditions.

According to the usage

There are feeding roller, front roller, back roller, transport roller, extension roller, working roller, collection roller and special purpose roller, such as in-furnace roller, lifting roller, cooling roller and inspection roller.

Find the Perfect Fit

A hot rolling roller table, also known as a roller conveyor or roller bed, is a type of material handling equipment used in the hot rolling process of metal. It is designed to transport and support the metal stock as it undergoes the hot rolling process.

During hot rolling, metal ingots or billets are heated to high temperatures and then passed through a series of rolling mills to reduce their thickness and shape them into desired products, such as sheets, plates, or bars. The hot rolling roller table plays a crucial role in facilitating the movement of the metal stock through the rolling mills.

A hot rolling roller table typically consists of a series of parallel, rotating rollers that are evenly spaced and aligned along the length of the table.

Application Areas Of Roller Conveyors

Roller conveyors are widely used in various industrial fields, such as metallurgy, mining, building materials, chemical industry, electricity, etc.

In the metallurgical industry, roller conveyors are used for the transportation of materials such as steel billets and steel.
In the mining industry, roller conveyors are used for the transportation of materials such as ore and coal.
In the building materials industry, roller conveyors are used for transporting materials such as cement and bricks.
In the chemical industry, roller conveyors are used for the transportation of chemical raw materials, finished products, and other materials.
In the power industry, roller conveyors are used for the transportation of materials such as coal and fly ash.

Why Choose Roller Conveyors for Your Business?

The rollers are usually made of durable materials, such as steel, and are designed to withstand the high temperatures

and mechanical stresses encountered during hot rolling.

The metal stock is placed on top of the rollers and is guided and supported as it moves along the table. The rotation of the rollers helps to propel the metal stock forward, ensuring a smooth and controlled movement through the rolling mills. The roller table can be straight or curved, depending on the layout and configuration of the rolling mill.

In addition to supporting the metal stock, hot rolling roller tables may also include features such as cooling jets or water sprays to help control the temperature of the metal during the rolling process. These cooling mechanisms help prevent overheating and ensure the quality and integrity of the rolled products.

Hot rolling roller tables are designed to handle heavy loads and withstand the harsh conditions of the hot rolling process. They are essential for maintaining the continuous flow of metal stock through the rolling mills, ensuring efficient production and high-quality rolled products.

Overall, a hot rolling roller table is a critical component in the hot rolling process, providing support, guidance, and

controlled movement of the metal stock as it undergoes deformation and shaping in the rolling mills.

Is Custom Roller Conveyor Design Right for You?

The main parameters of the roller table are roller diameter, roller length, roller distance, roller speed and the total length of the roller table in collective transmission. These parameters vary with the use of raw materials in the workshop, the shape and size of products, the conditions of process equipment and the layout of the workshop. When designing, the roller table will be selected correctly according to the needs and specific conditions. When selecting, we should also pay attention to the difficulty of processing and manufacturing and the variety of roller table, so as to save investment and facilitate installation and maintenance.

There are many ways to classify roller tables, which can generally be classified according to three methods:

FAQ

In order to ensure the normal operation of the roller table and prolong its service life, it is necessary to carry out regular maintenance.

1. Lubricating roller table

Regularly lubricate all parts of the roller table, such as roller bearings and driving devices. Select a suitable lubricant and lubricate it according to the specified lubrication cycle.
2. Check the control system

Regularly check the operation of the control system, such as whether the control buttons and indicator lights are normal. If there is any abnormality, it should be repaired in time.
3. Check the drive

Regularly check the operation of the driving device, such as whether the temperature and noise of the motor, reducer and other equipment are normal. If there is any abnormality, it should be repaired in time.
4. Check roller

Check the wear of the rollers regularly, and replace the rollers with serious wear in time. At the same time, check whether the rotation of the roller is flexible. If it is stuck, it should be repaired in time.
5. Clean roller table

Regularly clean the impurities such as dust and oil on the roller table and keep the roller table clean. Compressed air, brushes and other tools can be used for cleaning.
