For a tube mill, quick-change means adjusting or exchanging the necessary tooling, i.e. rolls, to make a new tube with a different wall thickness and/or outside diameter (OD). The conventional method takes about 60 minutes.with automated universal shaft disconnects and handling systems, changeover times of 15 minutes or less are possible.

This much speed time is very attractive, but there are pluses and minuses, and they should be weighed based on each individual situation. A most important factor is changeover frequency, which can range all the way from just once a month to as much as once a shift. Three shifts per day means fifteen changeovers per week, a good recommendation !

However, if you are purchasing a new mill and have expansion motives, you should certainly use roller quick change device.  The upfront cost to supply quick change device is small compared to the cost of the entire mill itself and, furthermore, the cost to upgrade later is going to be considerably higher. In other words, the sooner the better. Timing is everything.

Factory the need for rapid roll tooling changeovers on Pipe and Tube mills, where long changeovers mean higher inventories and/or eroding profits from excessive downtime. That’s why we offer a comprehensive selection of Quick Change Systems to choose from to greatly improve production up-time, all part of our philosophy of partnering with our customers, long term, to promote flexibility and efficient operations mandatory in today’s competitive marketplace.

The line adopts quick change system for the forming and sizing sections. The backup shafts can be pre-assembled with proper rollers. When switching, uses crown to load the shaft onto the production stands, settle the fixation bolt and connect to the transmission shaft (Transmission shaft is designed as quick-dissemble type which requires no is mount of flange plate screw). The dissemble of shaft utilize hydraulic system for easy operation. This kind of quick-change system has been tested in many scenarios which has proven to have perfectly deal with water back-flow issue and can simultaneously clear the scale cinder and dust while performing

Transmission shaft is designed as quick-dissemble type which requires no dismount of flange plate screw. The dissemble of shaft utilize hydraulic system for easy operation. Roller change period with quick-change system： Appr. 8 hours(typically 1.5-2 days needed without quick-change system).

The complete line is divided in three sections:

▪ Entry Section

▪ Forming, welding, Cooling and sizing Section

▪ Cutting and Delivery Section

Raw material (Steel Strip) in form of a coil is uncoiled and fed into forming section passing through the equipment of entry section. Entry section enables the tube mill to run continuously by using strip joining and accumulation equipment. Tube is formed in round shape passing through a set of driven and idler rollers of forming section before welding. In welding section tube id longitudinally welded by using high frequency induction welding method. Outside bead is removed and formed in shape of scrap. The weld seam is ironed and tube passes though the cooling section. In sizing section, tube is formed to specified size and converted into specified shape. After sizing, tube is cut to specified size and converted into specified shape. After sizing, tube is cut to specified length by using flying cutting equipment and delivered in collecting though passing through run out conveyor.
