Abstract
Abstract A removable slide guide for a slide closure arranged on containers for liquid melt, in particular steel ladles or intermediate containers. The slide closure includes a slide housing, an upper orifice plate and a support element carrying the slide plate and an outflow sleeve. A slide guide is provided with two mutually independent means of attachment for the purpose of arranging the slide guide on a slide housing attached to a metal jacket of the container. One of the means fixes the slide guide in its operational position on slide housing and, the other means of attachment holds the slide guide coupled to the slide housing. The first means of attachment are released in a position suitable for the replacement of parts subjected to wear in such a manner that the two means of attachment do not mutually impede each other when the slide guide is fixed in the required operational position on the slide housing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
195 words
In a side closure for the pouring spout of metal melt containing vessels, such as steel pouring ladles, such slide closure including a slide housing on said vessel adjacent said spout thereof, a refractory orifice plate fixedly positioned against said vessel, a refractory slide plate having a refractory outflow sleeve attached thereto, a supporting element mounting said slide plate within said slide housing for sliding movement against said orifice plate, and a slide guide removably attached to said slide housing for guiding the sliding movemet of said supporting element, the improvement comprising: first attachment means for rigidly attaching said slide guide to said slide housing in the operational position thereof; second attachment means for supporting said slide guide on said slide housing but to allow movement of said slide guide away from said slide plate when said first attachment means are released to remove said slide guide from said operational position, to thus allow removal of worn refractory elements; and said first and second attachment means being positioned to prevent hinderance of the operation of said first attachment means by said second attachment means during the fixing of said slide guide in said operational position.
Claim 2
Dependent Claim

In a side closure for the pouring spout of metal melt containing vessels, such as steel pouring ladles, such slide closure including a slide housing on said vessel adjacent said spout thereof, a refractory orifice plate fixedly positioned against said vessel, a refractory slide plate having a refractory outflow sleeve attached thereto, a supporting element mounting said slide plate within said slide housing for sliding movement against said orifice plate, and a slide guide removably attached to said slide housing for guiding the sliding movemet of said supporting element, the improvement comprising: first attachment means for rigidly attaching said slide guide to said slide housing in the operational position thereof; second attachment means for supporting said slide guide on said slide housing but to allow movement of said slide guide away from said slide plate when said first attachment means are released to remove said slide guide from said operational position, to thus allow removal of worn refractory elements; and said first and second attachment means being positioned to prevent hinderance of the operation of said first attachment means by said second attachment means during the fixing of said slide guide in said operational position.
Claim 3
Dependent Claim
43 words
The improvement claimed in claim 1, wherein said second attachment means comprises a hinge connection connecting said slide guide to said slide housing, said slide guide being pivotable about said hinge connection away from said slide plate when said first attachment is released.
Claim 4
Dependent Claim
64 words
The improvement claimed in claim 2, wherein said hinge connection comprises at least one hinge member on said slide housing and at least onE hinge member on said slide guide, said hinge members each having an opening there-through, and a hinge pin extending through said openings, the size of at least one of said openings being greater than the size of said hinge pin.
Claim 5
Dependent Claim
41 words
The improvement claimed in claim 1, wherein said second attachment means comprises flexible holding means attached to said slide guide and to said slide housing to allow said slide guide to be moved downwardly when said first attachment means are released.
Claim 6
Dependent Claim
30 words
The improvement claimed in claim 1, wherein said second attachment means comprises a guide rod attached to said slide housing, said slide guide being slidably mounted on said guide rod.
Claim 7
Dependent Claim
