Open the CIPO recordAbstract From the Canadian patent
On detection of an occurrence of skin sticking in the mould, the withdrawal speed is subjected to a cyclic variation which comprises a ramp from the cruising speed to a reduced, decelerated speed, a healing plateau and an acceleration ramp from the reduced speed to the cruising speed, measures are taken to determine the ferritic potential (PF) of the steel which is being cast, to determine the gradients (D, A) of one of the two ramps as a function of this ferritic potential and to determine the length (tr) of the healing plateau as a function of the difference between the liquidus and solidus temperatures of said steel.

Why it's free to use
- Filed March 30, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 30, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 30, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
