Invimec to install new 5-head rolling mill for precious metal bars

Invimec, a reference point in the precious metal rolling sector and in the production of machinery for various industrial sectors, is happy to celebrate another success: the company has recently completed an important order with the installation of a new 5-head rolling mill for precious metal bars.

The ENNE245 is a multi-stand tandem rolling mill, featuring an exclusive reversibility function. This automatic mechanism allows the semi-finished product to be unwound and rewound without operator intervention, thus optimizing processing times.

The strip is fed into the first rolling cage, passes through the rollers and is automatically guided to the next cage. It is possible to choose to work with all the stands or only some of them, and also to repeat the same sequences to achieve the desired thickness. The high-carbon steel rolling rollers have a diameter of 245 mm and are 160 mm wide.

The bars and strips that undergo rolling can have a maximum width of 80 mm and a maximum thickness of 28 mm. During the different processing cycles, the thickness of the bar can be reduced to 1 mm.

The rolling mill is suitable for reducing the thickness of various metals, such as:

- precious metals (gold, silver, platinum);
- special and exotic alloys (niobium, zirconium, molybdenum, etc.);
- copper and its alloys;
- brass and its alloys;
- aluminum alloys;
- welding and braze welding alloys and wires;
- special steel alloys (high-alloy steels, special steels, etc.);
- bimetallic and trimetallic products;
- difficult-to-draw materials.

The innovations introduced by Invimec to improve the technology of its rolling mill bring numerous advantages in terms of optimizing thickness reduction times, reducing the number of annealing operations, and automatically adjusting the material tension.
