(New Zealand steel mill cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to steel mill cylinder:

The piston rod of the steel mill cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

The main role of the steel mill cylinder: the steel mill cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the steel mill cylinder realizes reciprocating motion. The structure of the steel mill cylinder has three categories: piston steel mill cylinder, plunger steel mill cylinder, swing steel mill cylinder, piston steel mill cylinder and plunger steel mill cylinder to achieve reciprocating linear motion, output speed and thrust, swing steel mill cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the steel mill cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The steel mill cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

Piston steel mill cylinder is widely used in hydraulic transmission. When the steel mill cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the steel mill cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the steel mill cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

When the steel mill cylinder is in use, ensure that the steel mill cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.

Answers to some questions about steel mill cylinder:

How is the hydraulic cylinder selected in the mechanical design manual?
First of all, it is necessary to meet your work needs, and the second is to meet the structural space of the cylinder and accessories. Three to consider the other parameters of the cylinder.

How is the hydraulic cylinder tempered?
The purpose of the tempering treatment is to make the piston rod have comprehensive mechanical properties of strength, hardness, plasticity and toughness, and the internal structure is uniform and fine tempered sorbite, so as to prepare the organization for subsequent surface quenching. The length of the long cylinder piston rod is 3800-4200, and the diameter is Φ90-Φ110mm, so its heating equipment uses a 150KW well resistance furnace or 600KW suspension continuous resistance heating furnace, and the temperature is controlled by two areas. Heat treatment process parameters: in the shaft furnace, a furnace is suspended with 4 pieces, the quenching heating temperature is 830±10℃, and after holding heat for 160min, it is divided into two times for quenching, and two pieces are quenched each time, and the circulating cooling water is used for cooling.
