What is the difference between a four-roll plate rolling machine and a three-roll plate rolling machine?

First, the number of rolls is different: a three-roll plate rolling machine has 3 rolls, while a four-roll plate rolling machine has 4 rolls.

Second, the processing accuracy is different: the processing accuracy of the three-roll plate rolling machine is lower than that of the four-roll plate rolling machine, and the four-roll plate rolling machine can achieve higher processing accuracy.

Third, the processing efficiency is different: the processing efficiency of the three-roll plate rolling machine is lower than that of the four-roll plate rolling machine, and the four-roll plate rolling machine can achieve higher processing efficiency.Last but not least, there is a price difference: the price of a three-roll plate rolling machine is lower than that of a four-roll plate rolling machine.

Could you introduce the types of plate rolling machines?

According to the number of rolls, they can be divided into: two-roll plate rolling machines, three-roll plate rolling machines, and four-roll plate rolling machines.

According to the different arrangement positions of the roll shafts, they can be divided into symmetric and asymmetric rolling mills. According to the different pre-bending functions, they can be divided into: those with pre-bending function and those without pre-bending function.According to the different ways of applying pressure, they can be divided into mechanical plate rolling machines and hydraulic plate rolling machines. According to the different control methods, they can be divided into: electronic control, digital display, and numerical control.

How to choose the model of the plate rolling machine?

Mechanical asymmetric three-roll plate rolling machines are used for rolling thin plates, and mechanical plate rolling machines have a pre-bending function.Mechanical symmetric three-roll plate rolling machines are suitable for plates with a thickness of less than 30mm, and mechanical plate rolling machines do not have a pre-bending function.The upper roll universal three-roll plate rolling machine is suitable for plates with a thickness of more than 20mm. It is a hydraulic plate rolling machine with a pre-bending function. It can also be used for plates with a thickness of less than 20mm, but the price is higher.Four-roll rolling mills are suitable for all plate thicknesses.

What are the key points for purchasing a plate rolling machine?

First, you need to provide us with your maximum plate width and plate thickness. In addition, if you have specific bending requirements, please provide them together, and we will recommend a suitable machine model based on this information.Second, choose a professional plate rolling machine manufacturer. As a plate rolling machine manufacturer with 25 years of experience, Wuxi Shenchong plate rolling machines are sold to more than 80 countries. We have skilled engineers who can design rolling solutions and solve all your bending problems.

How are plate rolling machines transported?

Whether it is your first time importing a machine, we will help you solve all transportation problems. We have long-term cooperative freight forwarders, so we accept FOB, CIF or door-to-door delivery. You just need to wait for your machine. If you purchase a hydraulic plate rolling machine, we will provide you with foundation drawings, and you need to prepare the foundation in your factory.

What is the difference between a plate rolling machine and a profile bending machine?A plate rolling machine is a machine used for rolling thin plates, while a profile bending machine is used for rolling profiles such as flat steel, square steel, round steel, angle steel, I-steel, H-steel, square tubes, rectangular tubes, round tubes, etc.
