Abstract
Abstract A horizontally movable sampling probe, for insertion into and retraction from a blast furnace, is supported in an aperture in the furnace wall. The support mechanism for the probe includes a fluid cooled guide block attached to the furnace shell and having a support portion extending toward the furnace interior at least part way through the refractory furnace wall lining.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
228 words
A support mechanism for a measuring probe, the probe being intended to be introduced in a horizontal direction into a furnace via an aperture in the furnace wall, the furnace wall being defined by an outer metal casing and inner lining of refractory material, the probe support comprising: flange means mounted on the furnace casing at the exterior of the furnace, said flange means being coaxial with the aperture in the furnace wall; guide block means supported from said flange means, said guide block means at least partly extending into said flange means and being provided with a through hole sized to permit passage of the probe; support platform means, said support platform means extending from said guide block means to an end in the furnace wall aperture a distance which is at least half the thickness of the refractory lining, said support platform means having a probe guide groove which is coaxial with said guide block means through-hole; support means in said guide groove adjacent said end of said support platform means for supporting the furnace probe from below at a point adjacent said end of said support platform means; and means for establishing a flow of pressurized gas through said guide block means through hole and over a portion of said support platform means to thereby prevent the accumulation of particulate matter on the surfaces thereof.
Claim 2
Dependent Claim
228 words
A support mechanism for a measuring probe, the probe being intended to be introduced in a horizontal direction into a furnace via an aperture in the furnace wall, the furnace wall being defined by an outer metal casing and inner lining of refractory material, the probe support comprising: flange means mounted on the furnace casing at the exterior of the furnace, said flange means being coaxial with the aperture in the furnace wall; guide block means supported from said flange means, said guide block means at least partly extending into said flange means and being provided with a through hole sized to permit passage of the probe; support platform means, said support platform means extending from said guide block means to an end in the furnace wall aperture a distance which is at least half the thickness of the refractory lining, said support platform means having a probe guide groove which is coaxial with said guide block means through-hole; support means in said guide groove adjacent said end of said support platform means for supporting the furnace probe from below at a point adjacent said end of said support platform means; and means for establishing a flow of pressurized gas through said guide block means through hole and over a portion of said support platform means to thereby prevent the accumulation of particulate matter on the surfaces thereof.
Claim 3
Dependent Claim
22 words
The apparatus of claim 1 further comprising: means for circulating a coolant through said guide block means and said support platform means.
Claim 4
Dependent Claim
31 words
The apparatus of claim 2 wherein said guide groove of said support platform means is generally C-shaped and has a radius equal to the radius of the guide block means through-hole.
Claim 5
Independent Claim
33 words
The apparatus of claims 2 or 3 further comprising: insert means positioned to the exterior of the furnace for contacting the upper side of the probe to reduce reactions occuring in the probe.
Claim 6
Dependent Claim
40 words
The apparatus of claim 1 wherein said guide groove adjacent said end of said support platform means is provided with a facing of a refractory material to constitute the sole support for the bottom of the probe within the support.
Claim 7
Dependent Claim
22 words
The apparatus of claim 1 further comprising: means for circulating a coolant through said guide block means and said support platform means.
Claim 8
Dependent Claim
31 words
The apparatus of claim 1 wherein said guide groove of said support platform means is generally C-shaped and has a radius equal to the radius of the guide block means through-hole.
Claim 9
Independent Claim
35 words
The apparatus of claims 1, 5, 6 or 7 further comprising: insert means positioned to the exterior of the furnace for contacting the upper side of the probe to reduce reactions occuring in the probe.
