01.Hot delivery and hot charging line for tube billets

The company independently designed and used the hot charging and hot delivery process for tube billets, built a hot delivery and hot charging line for tube billets, and used a special hot delivery roller to transport hot continuous casting tube billets of φ180-350mm. The temperature of the tube billets entering the furnace reached 600-700℃. The hot charging and hot delivery device has a high degree of automation, fast tube billet transportation rhythm and high efficiency. By taking insulation measures around the conveying roller, the insulation effect is enhanced, which can reduce the heat loss during the tube billet transportation process, greatly shorten the tube billet heating time, improve the production rhythm, save energy, and ensure that the tube billet has a high rolling temperature to increase the service life of the tooling and improve the product quality.

02.High speed hot saw

The company has three domestically pioneering walking-beam heating furnaces equipped with three high-speed hot saws. It creatively uses a walking-beam heating furnace to correspond to two pipe rolling production lines after sawing with a high-speed hot saw. The high-speed hot saw adopts a large flywheel energy storage method to achieve fixed-length cutting of long pipe billets with a temperature of up to 1100℃~1300℃. The hot saw blade rotates at a speed of up to 1100 rpm, and a single cut takes only 1 second, which fully meets the needs of fast cutting after the hot billets are out of the furnace. The travel of the hot saw machine is all automatically controlled, with accurate positioning and a high degree of automation.

03.Continuous pipe mill

The company has six sets of limited mandrel continuous tube mills, including 2 sets of 6-stand 2-roller rolling mills, 2 sets of 6-stand 3-roller rolling mills, and 2 sets of 5-stand 3-roller rolling mills. All of them are side-opening type. The units have high rolling stability and automation. They can collect continuous rolling mill equipment and production data in real time, simulate and emulate the rolling process using mathematical models, and automatically evaluate the service life based on the online use of tools and dies.

04.Reducer (Sizing machine)

The company has 6 tension reducers (sizing mills) with CEC control function, which can effectively reduce the loss of cutting head and tail. It adopts a separate motor drive, and the motor output torque distribution is more uniform, which is convenient for CEC control and has good speed rigidity. The rolling center line of the tension reducer (sizing mill) is guaranteed by processing and corrected by the same optical linear instrument as the continuous rolling mill.

05.Magnetic flux leakage detector

Equipped with 17 magnetic flux leakage flaw detectors, using the latest patented technology, a unique composite probe array is installed in the probe shoe, and combined with multi-channel processing technology and special software, it can reliably detect internal and external defects of steel pipes and improve the detection capability of oblique defects. The flaw detection sensitivity is at the leading level at home and abroad; the equipment has strong magnetization and a small detection blind area; the probe shoe adopts a follow-up centering design with good tracking performance, and combined with a multi-channel high-speed signal acquisition and processing system, it can achieve high-speed and stable flaw detection, and the flaw detection speed can be adjusted according to the production rhythm.

06.High pressure water pressure testing machine

The company has a high-pressure water pressure testing machine to check for defects in steel pipes and couplings. The test pressure is 10-70MPa, and the frequency is ≥80 pieces/hour. The hydraulic press uses a large radial gap seal to seal both ends of the steel pipe, and then fills the steel pipe with high-pressure water and maintains pressure to check for leakage of the steel pipe. The test results are saved in the database through data collection for traceability query.
