Method And Device For Producing Hot Metallic Strip, In Particular From Lightweight Structural Steel

A method of producing a hot metallic strip, comprising the steps of:

• charging a melt by means of a runner onto a circulating casting belt of a horizontal strip casting facility in the presence of inert gas;
• allowing the melt to solidify to form a pre-strip with a thickness between 6 to 20 mm;
• and
• causing the casting belt to locally vibrate so as to reduce a heat transfer and a contact between the solidifying melt and the casting belt.

A device for producing a hot metallic strip, comprising:

• a feed vessel which contains the melt and has a horizontal runner;
• a primary cooling zone downstream of the feed vessel and including two deflection pulleys and a circulating cooled casting belt routed over the deflection pulleys for allowing melt, received from the runner, to solidify, said casting belt being configured with a structure;
• a secondary cooling zone downstream of the primary cooling zone and including an enclosed roller table for further solidification of the melt to form a pre-strip;
• and
• a vibratory unit arranged beneath the casting belt to cause vibrations of the casting belt.
