Continuous casting steel billet online hot-wire jet printing machine

Abstract

The invention discloses a continuous casting steel billet online hot-wire jet printing machine, which comprises a transversely-shifting mechanism, a longitudinally-shifting mechanism, an X/Y two-dimensional writing mechanism, an electric arc spraying system, a descaling mechanism and a pneumatic system. The longitudinally-shifting mechanism is arranged on a transversely-longitudinally shifting supporting base of the transversely-shifting mechanism, a spraying power supply in the arc spraying system, the pneumatic system, a wire disc of the arc spraying system, the X/Y two-dimensional writing mechanism and the descaling mechanism are arranged on a longitudinally-shifting supporting base of the longitudinally-shifting mechanism along a longitudinal drag chain from left to right in turn. The jet printing machine melts metal wires through arc heat generated between two metal wires which are fed at a constant speed, atomizes the melted metal into particles through high-speed airflow and accelerates the particles, the metal particles after the atomization are sprayed to the continuous casting billet surface by a special cluster-type nozzle, and the nozzle perform high-speed motion according to a preset character track under the drive of the X/Y two-dimensional writing mechanism, thus characters are formed on the continuous casting billet surface. The continuous casting steel billet online hot-wire jet printing machine can perform metal jet printing on hot metal continuous casting steel billets.

Description

technical field [0001] The invention relates to an on-line thermal metal jet printing machine for continuous casting billets. Background technique [0002] In the continuous casting production of large metallurgical enterprises, in order to carry out quality tracking management and provide the traceability basis of the billet production process, the billet must be marked in a timely manner during the processing process - a set of letters and numbers to indicate the furnace number, tank number, Steel code, stream number and billet number, etc. Once a quality problem occurs, the production date, furnace number, batch number, corresponding arrival status and other relevant information can be traced according to the identification, providing reliable information for finding and solving problems. On the other hand, it also improves the competitiveness of my country's steel billets in the international market. [0003] The billet marking work in the continuous casting production...
