Abstract

Abstract A single piece ceramic body has an inlet chamber, an inlet duct and a disc-shaped cavity, that latter cavity is, as far as the body is concerned, of open construction but the opening is closed by a plug. That plug may contain one or two thermo elements, and the inlet chamber may be constructed as an opening with a partitioning sheet or as a duct system with a lateral port and a slag trapping dome. The mold cavity has also venting opening.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 99 words
A ceramic sampling device for sampling molten steel, comprising: a single piece body having an entrance chamber, an inlet duct extending from the chamber to a mold cavity of disc-shaped configuration, but being defined by an open configuration of the body, the body further including a venting duct and destructible means for closing the venting duct; and a stopper inserted into and affixed to the body at said open configuration and providing a mold-completing surface as to one flat side of the disc, said stopper and mold completing surface having a diameter equal to the diameter of the disc.
Claim 2
Dependent Claim 99 words
A ceramic sampling device for sampling molten steel, comprising: a single piece body having an entrance chamber, an inlet duct extending from the chamber to a mold cavity of disc-shaped configuration, but being defined by an open configuration of the body, the body further including a venting duct and destructible means for closing the venting duct; and a stopper inserted into and affixed to the body at said open configuration and providing a mold-completing surface as to one flat side of the disc, said stopper and mold completing surface having a diameter equal to the diameter of the disc.
Claim 3
Dependent Claim 70 words
A sampling device as in claim 1, wherein the inlet duct leads into a low point of the mold cavity, the venting duct leads from a high point in the mold cavity, the body having means for connection to a tubular holder, the venting duct having an exit off the means for means for connection so that venting does not occur into the interior of the tubular holder when connected.
Claim 4
Dependent Claim 142 words
A ceramic sampling device for sampling molten steel, comprising: a single piece body constructed in its upper part for connection to a tubular holder and having an entrance chamber, an inlet duct extending from the chamber to a mold cavity of disc-shaped configuration, upright orientation and being further defined by an open, laterally oriented configuration of the body, the body including a venting duct with an exit offset from the upper art so that venting will occur outside of the interior of the tubular holder when connected to the body; destructible means for closing the venting duct; and a ceramic stopper inserted into and affixed to the body at said open configuration and providing an upright mold-completing surface as to one flat side of the disc, said stopper and mold completing surface having a diameter equal to the diameter of the disc.
Claim 5
Dependent Claim 142 words
A ceramic sampling device for sampling molten steel, comprising: a single piece body constructed in its upper part for connection to a tubular holder and having an entrance chamber, an inlet duct extending from the chamber to a mold cavity of disc-shaped configuration, upright orientation and being further defined by an open, laterally oriented configuration of the body, the body including a venting duct with an exit offset from the upper art so that venting will occur outside of the interior of the tubular holder when connected to the body; destructible means for closing the venting duct; and a ceramic stopper inserted into and affixed to the body at said open configuration and providing an upright mold-completing surface as to one flat side of the disc, said stopper and mold completing surface having a diameter equal to the diameter of the disc.
Claim 6
Dependent Claim 144 words
A ceramic sampling device for sampling molten steel, comprising: a single piece body constructed in its upper part for connection to a tubular holder and having an entrance chamber, an inlet duct extending from the chamber to a mold cavity of flat disc-shaped configuration, being oriented essentially transversally to the duct, but being defined by an open configuration of the body at its upper part; the body including a venting duct with an exit offest from the upper art so that venting will occur outside of the interior of the tubular holder when connected to the body; and a ceramic stopper inserted into and affixed to the body at said open configuration from the top and providing a moldcompleting surface as to one flat side of the disc, said stopper and mold completing surface having a diameter equal to the diameter of the disc.
Claim 7
Dependent Claim 144 words
A ceramic sampling device for sampling molten steel, comprising: a single piece body constructed in its upper part for connection to a tubular holder and having an entrance chamber, an inlet duct extending from the chamber to a mold cavity of flat disc-shaped configuration, being oriented essentially transversally to the duct, but being defined by an open configuration of the body at its upper part; the body including a venting duct with an exit offest from the upper art so that venting will occur outside of the interior of the tubular holder when connected to the body; and a ceramic stopper inserted into and affixed to the body at said open configuration from the top and providing a moldcompleting surface as to one flat side of the disc, said stopper and mold completing surface having a diameter equal to the diameter of the disc.
Claim 8
Dependent Claim 40 words
A sampling device as in claim 4, said disc-shaped mold cavity having an oblique position relative to a vertical axis, but being centrally oriented to said axis and having a peripheral surface being of cylindrical configuration relative to said axis.
Claim 9
Dependent Claim 28 words
A sampling device as in claim 5, said inlet duct being disposed excentrical to said axis, said peripheral surface portion having an oblique portion adjacent to the duct.
Claim 10
Dependent Claim 30 words
A sampling device as in claim 1, said entrance chamber being at the bottom of the body, there being at least one sheet metal closure in or at said chamber.
Claim 11
Dependent Claim 16 words
A sampling device as in claim 1, said stopper including at least one thermo sensing element.
Claim 12
Dependent Claim 16 words
A sampling device as in claim 8, said thermo sensing element projecting into the mold cavity.
Claim 13
Dependent Claim 25 words
A sampling device as in claim 8, said stopper having a recess receiving the thermo sensing element, being exposed to the exterior of the body.
Claim 14
Dependent Claim 112 words
A ceramic sampling device for sampling molten steel, comprising: a single piece body having an entrance chamber, an inlet duct extending from the chamber to a mold cavity of disc-shaped configuration, but being defined by an open configuration of the body, said inlet duct and said entrance chamber forming a U-shaped duct system, the entrance chamber having a lateral entrance part off one of the legs of the U; and a stopper inserted into and affixed to the body at said open configuration and providing a mold-completing surface as to one flat side of the disc, said stopper and mold completing surface having a diameter equal to the diameter of the disc.
Claim 15
Dependent Claim 112 words
A ceramic sampling device for sampling molten steel, comprising: a single piece body having an entrance chamber, an inlet duct extending from the chamber to a mold cavity of disc-shaped configuration, but being defined by an open configuration of the body, said inlet duct and said entrance chamber forming a U-shaped duct system, the entrance chamber having a lateral entrance part off one of the legs of the U; and a stopper inserted into and affixed to the body at said open configuration and providing a mold-completing surface as to one flat side of the disc, said stopper and mold completing surface having a diameter equal to the diameter of the disc.
