181	DISASSEMBLING AND REMOVING METHOD FOR CHECKER BRICK IN HOT STOVE	JP9383180	1980-07-11	JPS5719311A	1982-02-01	HAGIMORI JIYUNICHIROU; KOBAYASHI TOSHIHIKO; SAEKI AKIRA
PURPOSE:To safely disassemble and to remove checker bricks without allowing broken pieces and dust scatter to the outside by piercing an opening on the side opposite from the partition wall in the lower part of a hot stove, and exploding explosive compounds within the vent holes of the bricks. CONSTITUTION:An opening part 6 is pierced in a shell 4 on the side opposite from a partition wall 9 above the receiving plate 8 in the lower part of a hot stove 2. Thence, explosive compounds are loaded in the vent holes of lower checker bricks 12 and the vent holes of upper checker bricks 13, respectively. If the bricks 12, 13 are explosively broken by exploding said explosive compounds, the vent holes annihilate and cavities are formed. At the same time, the broken brick 12 parts are automatically discharged through the part 6 by explosive forces. Further, the bricks 13 fall into the cavity parts, and repeat collision with each other, by which they are segmented to small pieces and are automatically flowed away from the part 6. According to this method, the disassembling work is accomplished instantaneously without damaging the shell 4.

197	Hot-blast main for hot-blast stove system of a blast furnace	US139111	1993-10-21	US5358223A	1994-10-25	Nicolaas G. J. Bleijendaal; Jacob Felthuis; Ronald J. M. Stokman
A hot-blast main for a hot-blast stove system of a blast furnace has a refractory structure comprising a plurality of courses of refractory bricks. At least a first one of the courses has at least one part thereof comprised of a plurality of expansion-joint forming bricks whose dimensions and arrangement are such that, in the cold condition of the hot blast main, there are provided radial expansion joints between the expansion-joint forming bricks and at least one adjacent part of the hot-blast main. At least some of the expansion-joint forming bricks of the first course are placed radially staggered relative to at least one adjacent such brick in each case, so that the expansion joints are provided at both the radially inner side and the radially outer side of said first course. This construction accommodates differential thermal expansions and provides good stability of the structure.
198	Method for reducing stress corrosion cracking in high-temperature regenerative air heaters	US371977	1982-04-26	US4444555A	1984-04-24	Horace B. Edwardsen; Donald J. Shellenberger
Stress corrosion cracking which occurs in metallic portions of a high-temperature regenerative air heater can be alleviated by the disclosed methods. The methods include the step of storing a gas charge within a heated regenerative air heater, which gas charge is substantially devoid of free oxygen. The substantial absence of free oxygen from the gas charge prevents or reduces formation of nitrogen-containing oxides which typically form within an air-containing gas charge stored in a regenerative air heater held at high temperature. Conditions conducive to stress corrosion cracking are thereby alleviated by reduction of these nitrogen-containing oxides which are precursors to corrosive acids. The methods are particularly suitable for reducing stress corrosion cracking in blast furnace stoves.
199	Blast furnace stove	US92447	1979-11-08	US4290751A	1981-09-22	William H. Malone; John Fischley; Harry L. Anderson; Edward J. Spirko
A hot blast stove for preheating combustion air for an associated blast furnace, having a continuous, substantially cylindrical shaped peripheral wall extending from a base to a domed cover. The peripheral wall includes a first cylindrical portion defined by a refractory ring wall of a predetermined thickness, surrounded by insulation, and enclosed by a continuous metal shell; and, a second, diametrically larger, cylindrical portion disposed above the first cylindrical portion, defined by a continuation of the refractory ring wall of the first portion, surrounded by a predetermined thickness of insulating brick and insulation. The second portion is enclosed by a continuous metal shell which joins the domed cover. An annular interconnecting portion joins the cylindrical portions and includes a metal shell that diverges outwardly from the metal shell of the first portion to obliquely join the metal shell of the cylindrical portion. The interconnecting metal shell provides support for tapered insulating bricks which in turn support the insulating brick in the second portion. Alternately, the interconnecting portion includes nontapered insulating bricks and castable insulation between the shell and the ringwall.
200	Hot blast stove erection process	US935706	1978-08-21	US4221537A	1980-09-09	Ronald S. Mamula; Samuel C. Dotson
A process of erecting interior combustion and checker chambers in a hot blast stove by lining the checker chamber and building the chamber wall from a vertically movable scaffold in the checker chamber shaped to conform with the interior thereof, laying up checkerwork in the checker chamber beneath the movable scaffold, these two operations being supplied from outside the stove through feed openings at progressive heights, and lining the combustion chamber from a vertically movable work scaffold within the combustion chamber. All three principal operations are carried on concurrently.
