    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： 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.
