Continuous-casting mold

Claim 1

A mold for forming a continuous-cast strand of molten metal comprising: a. an inner first tubular envelope defining a mold cavity for receiving molten metal; b. an outer second tubular envelope surrounding said first tubular envelope in spaced apart relation; c. means connecting the extremities of said first and second envelopes to create a fluidtight first annular space therebetween; d. a third tubular envelope mounted in said annular space and in close spaced relation to said first tubular envelop whereby a second narrow annulus is created between said first and third tubular envelopes; e. a diaphragm extending across and subdividing the annular space between the third and second envelopes into third and fourth fluidtight annular spaces; f. means to introduce cooling fluid into the third annular space whereby said fluid courses the second annular space and thereafter flows into said fourth annular space; g. means to remove said cooling fluid from said fourth annular space; and h. vibratory means mounted adjacent said second envelope and having means extending through said second envelope so as to contact said first envelope whereby, when said vibratory means is actuated, said first envelope vibrates against said cast strand.
