The flywheel of the rolling mill is subjected to impact load during rolling. The rolling mill drives the rolling mill through the flywheel and reducer. A part of the load is released by the flywheel. The main drive of the rolling mill requires high dynamic response and high overload capacity. Flywheels are widely used in cutting machines, stamping machinery, etc. The spokes of the flywheel adopt a ring-shaped planar plate structure whose thickness is close to that of the flywheel. The flywheel of the rolling mill works in the best condition, which can reduce the heat of the motor and save power.

When the rolling mill is under load, the flywheel of the rolling mill slows down and releases energy to help the motor overcome the peak load. The thickness of the connection between the spokes and the hub is small. Therefore, the structural defects such as stress concentration at the connection and cracks are eliminated. Increase the thickness of the flywheel and reduce the diameter of the flywheel under changing conditions are also conducive to uniform stress distribution and increase the load-bearing capacity. When there is no load in the gap, the flywheel accelerates and stores energy, so the motor load can be evened. When disassembling the flywheel and pulley of the rolling mill , When tightening the nut, etc., it is strictly forbidden to use a hammer or hardened steel parts to hit, and the static balance of the flywheel should also be tested during installation.

The new high-output rolling mill equipment is equipped with online multiple straightening machines and cold cut-to-length flying shears behind the cooling bed. The rolled pieces are straightened by multiple lengths of the entire length of the cooling bed, followed by shearing blades. A flying shear with a pass cuts the rolled piece into commercial cut-to-length lengths. The rack-type stepping cooling bed is used to cool the rolled parts evenly, and the simple section steel such as round steel, rebar and other simple cross-section steels have good flatness after cooling, and can be delivered without straightening. For channel steel, angle steel, I-beam and other profiled materials, they need to be straightened after being cooled by a cooling bed. The double ruler is redundant and straightened, the number of head bites is greatly reduced, there are fewer accidents, and the efficiency is high. Using this technology and equipment, the production is mechanized and the degree of automation is high, which greatly reduces the finishing area and operators.
The steel rolling mill opens the energy-saving and environmental protection route in the future. With the acceleration of industrialization and urbanization, and the rapid increase of motor vehicles, the air quality of our cities is facing an unprecedented test, and the high detection of diseases caused by the haze weather is becoming the focus of public concern. Energy conservation and environmental protection is listed as a key development path in my country’s national policy. The reason it has been emphasized many times is because of the continuous shortage of energy in my country. The cruel reality has been calling for all of our rolling mill production line manufacturers to be cautious about the future development of rolling mills. direction. The gradual depletion of resources, the shortage of power supply in the power sector, and the deteriorating environment have all been clearly before each of us. It is up to everyone to make their best efforts to reduce environmental pollution and energy-saving steel rolling equipment. Environmental protection, energy saving and high efficiency are the main themes of the future development of rolling mills. Only in this way can the development of rolling mills go further. For the current rolling equipment in terms of steel rolling wastewater, dust prevention and noise, although there have been great improvements, compared with those large international steel manufacturers, my country's steel industry has also encountered some problems, and there is still a big gap between the decline in production and sales growth. , But if you have a big direction, you will work harder.
The speed ratio of the rolling mill corresponds to that of the reducer. The rolling mill can save water to a large extent and save gas for the steel rolling furnace. The heating capacity of the steel rolling furnace can reach ten tons per hour. Put the action plan of the promised steel rolling enterprise into implementation as soon as possible. From an overall perspective, the overall benefits are very considerable. The steel rolling mill can greatly reduce manual operations. The billet is cooled by water with rolls. All of them are used and considered whether to provide more free carbon emission quotas for the European steel industry. The cleaning water can be recycled and reused, and then pumped to filter the new water. Area. This not only solves the wastewater balance problem, recovers the oxide scale of the steel billet in the washing water for precipitation, and because the water flow is sufficient, the water consumption in the rolling process is guaranteed, and the rolling process and rolling efficiency of the automatic rolling mill are improved.
