Abstract (en)

[origin: EP0564316A1] The invention applies to continuous casting of steel in a mould with cooled walls, which is driven in oscillatory movement with travel h and frequency f, for producing a product leaving the mould at a casting speed Vc, the metal being topped with a lubricant forming liquid slag, the downward speed of the ingot mould being greater than the casting speed Vc during a crust-forming time tN. According to the invention, without altering the nature of the lubricant, it is possible to adjust the casting speed Vc over a wide range in order to adapt to specified casting conditions, by acting in combination on the travel and on the frequency of the oscillations as a function of the chosen casting speed, so that, whatever the casting speed Vc, the rate Q of consumption of the lubricant and the crust-forming time tN are each held at a substantially constant optimum value over the entire adjustment range of the speed. <IMAGE>
