Back-swing spiral welded mill introduction:
The steel coils are unfolded and leveled by the mill equipment. And they are sent to the forming machine in a certain angle. Supplemented by a certain angle, the continual pipes are formed in the principle of three-roll rolling machine. Continual spiral welding is welded by submerged-arc welding machine. The uncoiling, coil detaching, leveling, steel cutting and welding are working on the fly-welding carriage. When the steel is welded, the fly welding carriage moves forward in the same speed with the host equipments. The host machine will not have the stop. After the steel welding finishing, fly welding carriage backs forward to the original position t owait another coil. This mode is called continuous production method with high efficiency, high pipe quality, rare welding repair and other advantages.
According to the different function of our products, the back swing spiral welded pipe mills are divides in to API standard model and national standard model. API standard model mainly produces the delivery pipe with petroleum or natural gas (long distance).the material and quality of the steel pipe need to be very good. The requirements for mill equipment and testing equipment also are very high. National standard model produces the pipe used for short distance delivery of natural gas or water, the pipeline construction in the city, the structure pipe, column pipe and so on. The requirements for the material and quality of the steel also are very high, second only to that of API standard.
Summary
The welded pipe mill is back swing continuous production spiral welded pipe mill with a flying welding car, a rear axle swing, and a steel plate edge positioning.
This mill is our company's most advanced model, with the following new and patented technology:
Forming machine automatic adjustment system
There is the centering button on the operation stand of uncoiler. When the button is switched on, the double cone heads will automatically centralize the mill centerline. Then, the coil center is consistent to the mill center. It is no need to adjust with the vertical rollers. The production efficiency is improved and the instability is decreased.
In addition, the unit also has the uncoiler plate tail bending device to avoid the difficulty of passing the tail; the cutting and butt welding at the butt joint separate structure, truly realizes the bevel function of the butt-welded steel plate.
The main objectives of the unit: product physical quality, production costs, various consumption indicators and labor productivity have reached the domestic advanced level.
The unit equipment is a complete spiral welded pipe equipment integrating mechanical, electrical automation control and hydraulic control.
The unit is designed and manufactured with safety protection devices for equipment and safety protection for operators. To protect the operational safety of important equipment and the safety of operators. For example, a pressure limit protection sensor is provided in the pressing mechanism of the leveling machine; the pressing mechanism of the delivery machine also has a self-protection function when the plate thickness suddenly changes.
Since the whole control system uses the bus technology, the equipment operating parameters are digitized, combined with the various levels of power protection devices and various sensor components set on the hardware, through the management of the system software, the various operating parameters can be transmitted to the control in real time. The center analyzes and processes the operating status of the control equipment in time, and can display these parameters on the HMI synchronously for the operator to perform timely and effective operation, so that the operability and safety of the whole unit are qualitative. improve.
The unit uses edge positioning.
