(Sweden rolling mill cylinder,produced by Hengyu Hydraulic Co., Ltd）

rolling mill cylinder are widely used in Sweden，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed rolling mill cylinder for customers from Sweden.

Introduction to rolling mill cylinder:

At the rated pressure, the thrust of the rolling mill cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the rolling mill cylinder is related to the diameter of the rolling mill cylinder, but not to the stroke of the rolling mill cylinder. Moreover, the larger the rolling mill cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the rolling mill cylinder.

The meaning of the rolling mill cylinder model marked by the rolling mill cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the rolling mill cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the rolling mill cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

How the cavitation of the rolling mill cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the rolling mill cylinder, resulting in corrosive damage to the parts.

rolling mill cylinder hydraulic oil selection: The recommended working oil viscosity of the rolling mill cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

Answers to some questions about rolling mill cylinder:

How to calculate the hydraulic cylinder pressure, how much pressure can put up how much weight?
There is a formula for air pressure, hydraulic pressure, water pressure: F=P×S type: f-cylinder or hydraulic cylinder output, unit is Newton (N) P- pressure, unit is Mpa S- effective area, unit is square millimeter (mm2), note: is the effective area, in the hydraulic cylinder to subtract the cross-sectional area of the piston rod.

What is the pressure provided for a 63-bore cylinder with a pressure of 2 mpa?
2 mpa pressure is equivalent to 20 kg per square centimeter, 6.3 cm straight longitude, 3.15 cm radius, square, multiplied by, calculated an area of about 31.5 square centimeters, multiplied by 20 kg, the pressure is about 630 kg.
