The first apparent impulse in an opposite direction may be due to the feudal disorders of the reign of William Rufus. But the dominant element in early Norman administration in England was baronial. ![]() These were not the only officials, for there was an important group of curial bishops, and a force of trained clerks was utilized in the work of the chancery, if not also in that of the treasury. THE lay officials employed by William the Conqueror, whether in central government or in ruling the shires, were regularly of baronial status. Round pipe diameter:Φ40-130mm,thickness:1.2-5.0mm,Q235 OR below grade.ĭriving motor :22KW (15 SERVO ( YASKAVA )įeeding motor :5.5KW 4.4 SERVO ( YASKAVA )īlade cutting motor :2 2 KW 18.The Sheriffs and the Administrative System of Henry I Used to precisely cut the pipe to length automatically under the condition that the pipe continuously delivered from the mill at high speed. The tube seam is welded under theįorming speed:75X45-80m/min;100X100-60m/min Due to the skin and the kindred effect, the high-frequency current is concentrated on the weld joint that is heated rapidly and reaches the welding temperature. ![]() The strip is fed into the forming machine by the feeding device in the mill and the forming roller continuously rotate and press the strip into the required shape. The electric motor of the accumulator frame : 55KWįorming & Sizing Mill adopts roller type forming principle and high-frequency induction welding. It can carry the strip steel to shape system and send the carry out material velocity information to electric control device.Īdvantage:storage more material,no strike to strip steel surfaceĬarry material going velocity:Vmax=120m/minĭirectly electric motor power of the press & carry:30KW Send-off material device: include frame, guide direction rolls, guide out roll of high or lower place. It can be used to storage the strip steel material from press& carry unit and it could be draw from the center send-off material roll. It is main include frame, electric motor, brake unit, circling direction transfer power axle of the reduce velocity, press & carry roll, pressure air system of guide roll, inspected velocity unit it can supply the strip steel to accumulator and the mean times it will transfer the carry velocity information to electric control system, when we demand stop carry the material to this unit, it will stop roll to the electric motor and press& carry material roll by the break, and also could adjust the velocity to carry electric motor and the unit carry material velocity.Īccumulator frame assemble: include the electric motor, frame, inner circle roll, out circle roll and pressure roll. This unit is main include in press& carry material device, accumulator assemble, carry off material unit, electric control unit. Shear and welder is used to cut the irregular ends of the strips and then connect the strips by welding. The leveling unit with 2 roll pinch and 5 roll leveling. This unit is main used to lead the new coil steel head feed into the flattener unit ter uncoiler unit bring the coil into the working place. straight head and pinch leveling machine.The main body is equipped with pneumatic system to satisfy the needs of expanding, contracting and braking of the mandrels.hydraulic expanding and Pneumatic driving coil out diameter It contains two main parts: main body and the fixed base. The uncoiler is of the structure of one cone. Forming speed:75X45-80m/min;100X100-60m/minĦm wide, 100m long, at least 5m high from Ceiling Rails to Ground.Ĭoil Loading → Uncoiling →Cutting and Welding →Horizontal Spiral Accumulator → Forming, HF welding, Deburring, Cooling, Sizing, Straightening →cutting saw → Packing → Storage.Mechanical properties: σb≤520Mpa,σs≤365MPa Material : Low carbon steel and low alloy constructional steel ![]() Adopting roll pass design, the production line can manufacture welded steel pipes with good quality machining and high precision assembling. HG127 High-Frequency Welded Pipe Production Line is designed to produce welded round pipes of Ф40~127mm in diameter and 1.5~4.5mm in wall thickness as well as 40×40-100×100mm square pipes with thickness from 1.5-4.5mm and deformed pipes of the corresponding size.
