  • Method and installation for producing “light steel” by continuous casting with gas inclusion
    Patent number: 6263953
    Abstract: The problem with continuous casting methods is the production in a single cast of structured material shapes presenting hollow cavities. To this end the invention provides for a continuous casting method comprising the following steps: a) the material is melted and a continuous strand formed from said material; b) the material strand is cooled or left to cool so that at least a part thereof has a temperature at which its structure is pasty; c) gas is introduced into that part of the material strand which has a pasty structure so as to form hollow cavities, the material strand being moved from the top towards the bottom; and d) the material is left to solidify. The invention also relates to a device for carrying out this method.
