Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
265 words
Mold for continuous casting of metal, comprising: a plurality of plates positioned to define the mold cavity and having surfaces for direct exposure to the mold cavity, there being means for cooling the plates; means for retaining the plates in a particular, mold defining position relation in mutual disengagement, so that a gap exists between respective adjoining two of said plates; a plurality of corner elements one each per respective two adJoining plates and separable from both said plates, a corner element of the plurality provided for cooperation with a first and a second plate of the plurality in the respective gap between them, the first and second plates arranged transverse to each other, the corner element being releasably secured to the first plate to form a mold cavity defining surface continuation thereof and extending into said gap; and means including the retaining means acting on the first plate and in the back of the corner element for urging the corner element against the second plate at a first joint therewith, independently from the securing of the corner element to the first plate, and normal to the first joint so that position retaining pressure force as between the first and second plate is transmitted, for sealing the first joint between the second plate and the corner piece, at least essentially exclusively through the corner element, there being at least a surface portion of mutual engagement and providing a second joint between the corner element and the first plate on which the clamping force acts also normal to the second joint for sealing the second joint.

Claim 3
Dependent Claim
72 words
Mold as set forth in claim 1, there being four plates arranged to define a mold of quadrangular cross section, there being four corner elements accordingly, the corner elements being releasably secured to two oppositely positioned ones of the four plates, the dimensions of the corner elements respectively perpendicularly to the plates of the two plates determining the dimension of the cavity in the direction of extension of the other two plates.
Claim 4
Dependent Claim
21 words
Mold as set forth in claim 1, the corner element having mechanical strength different from the mechanical strength of the plates.
Claim 5
Dependent Claim
23 words
Mold as set forth in claim 3, the corner element being made of an age-hardened copper alloy, the plates being made of copper.
Claim 6
Dependent Claim
29 words
Mold as set forth in claim 3, the corner element being made of heat treated copper, having lower mechanical strength than the plates, the plates being made of copper.
Claim 7
Dependent Claim
31 words
Mold as set forth in claim 3, the corner element being made of a heat treated copper alloy, having lower mechanical strength than the plates, the plates being made of copper.
Claim 8
Dependent Claim
27 words
Mold as set forth in claim 1, the second plate bearing against the corner element at a surface area of mutual engagement directly adjacent the mold cavity.
Claim 9
Dependent Claim
34 words
Mold as set forth in claim 7, the surface area of contact as extending in the direction of plate thickness of the second plate having dimension of about one third of the plate''s thickness.
Claim 10
Dependent Claim
26 words
Mold as set forth in claim 8, at least one of the remaining, nonengaging surface areas of second plate and of the corner element being bevelled.
Claim 11
Dependent Claim
40 words
Mold as in claim 1, there being a bar interposed between the second plate and the corner element and compression forces between the first and second plate having transmitted through the bar as interposed between second plate and corner element.
Claim 12
Dependent Claim
22 words
Mold as set forth in claim 10, the bar and corner element having higher mechanical strength than the first and second plates.
Claim 13
Dependent Claim
44 words
Mold as set forth in claim 10, at least one of the bar and of the corner element having a bevelled surface to form a gap, the bearing area of engagement between corner element and bar being between the gap and the mold cavity.
Claim 14
Dependent Claim
17 words
Mold as set forth in claim 1, the corner element being releasably bolted to the first plate.
Claim 15
Dependent Claim
34 words
Mold as set forth in claim 1, wherein at least parts of the joints are aligned and normal to the clamping force provided by the last means and acting edgewise into the second plate.
Claim 16
Dependent Claim
33 words
Mold as set forth in claim 14, the first plate having a recess, receiving the corner element, the second joint established in the bottom of the recess on which the corner element sits.
