Optimization of Heating Equipment

 

Uniform Heating Furnace Design: Advanced heating furnace structures such as walking - beam heating furnaces are adopted. In this kind of heating furnace, the walking - beam at the bottom of the furnace moves, enabling the steel to move gradually during the heating process and be heated more uniformly. Compared with traditional pusher - type heating furnaces, it can avoid local overheating or insufficient heating of the steel caused by piling during the heating process. For example, in the hot - rolling production lines of some large - scale steel enterprises, the temperature deviation of steel in the walking - beam heating furnace can be controlled within ±10°C.

 

Reasonable Distribution of Heating Power: The heating power is reasonably adjusted according to different areas of the heating furnace and the heating characteristics of the steel. In the entrance area of the heating furnace, because the steel temperature is low, a higher heating power is required to quickly raise the temperature. While in the area close to the exit, the power is appropriately reduced to prevent the steel from overheating. By precisely controlling the power output of heating elements (such as resistance wires or gas burners), the temperature uniformity of the steel during the heating process can be achieved. For example, through a computer - controlled system, the heating power is dynamically adjusted according to the position and temperature feedback of the steel, so that the temperature of each part of the steel rises uniformly.

Temperature Compensation Measures during the Rolling Process

 

 

Roller Temperature Control: The rollers will absorb the heat of the steel during the rolling process, resulting in a local temperature drop of the steel. To maintain the uniform temperature of the steel, the temperature of the rollers needs to be controlled. A combination of roller - cooling and - heating systems can be adopted. Before the rolling process begins, the rollers are pre - heated to a certain temperature through the heating system to reduce the temperature difference between the rollers and the steel. During the rolling process, the cooling system is started in a timely manner according to the temperature change of the rollers to prevent the rollers from getting too hot and affecting the temperature uniformity of the steel. For example, on some high - speed wire - rod rolling mills, the temperature of the rollers is controlled by the internally - circulating cooling medium (such as water or oil), so that the roller temperature is maintained within a stable range, thus ensuring the uniform temperature of the steel.

 

Reasonable Adjustment of Rolling Rhythm and Speed

 

 

Adjust Rolling Speed According to Temperature: During the rolling process, the temperature of the steel is monitored in real - time, and the rolling speed is adjusted according to the temperature. When the steel temperature is low, the rolling speed can be appropriately reduced, so that the steel has more time to absorb heat between the rollers and prevent the temperature from further dropping. When the temperature is high, the rolling speed is accelerated to reduce the residence time of the steel in a high - temperature environment and avoid local overheating. For example, in some wide - strip - steel rolling processes, the temperature of the steel is monitored in real - time through the infrared temperature sensors installed on the rolling line. When the temperature deviation exceeds the set value (such as ±15°C), the rolling speed is automatically adjusted to bring the steel temperature back to the normal range.
