摘要： The supporting structure of a technical installation made from a material that is not resistant to corrosion and whose inner wall at least temporarily contains a corrosive and abrasive gas-vapor mixture and is protected from acid corrosion by a gas-vapor mixture barrier. This barrier is either placed between a refractory coating (6) and a thermal insulating layer (7) or is integrated into the refractory layer (6) or in the thermal insulating layer (7). The mechanical protection from the permeation of the gas-vapor mixture though the thermal insulation (7) up to the inner wall of the supporting structure allows a thermal insulating material to be selected that has a distinctly reduced thermal conductivity and thus allows the temperature on the exterior of the supporting structure to be lowered reducing energy consumption and improving occupational safety.

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.
摘要翻译： 通过公开的方法可以缓解在高温再生式空气加热器的金属部分发生的应力腐蚀开裂。 这些方法包括将气体进料储存在加热再生空气加热器中的步骤，该气体装料基本上没有游离氧气。 从气体充电中实质上不存在游离氧可防止或减少存储在保持在高温下的再生式空气加热器中的含空气的气体中的含氮氧化物的形成。 因此通过还原这些作为腐蚀性酸的前体的含氮氧化物，有利于应力腐蚀开裂的条件。 该方法特别适用于减少高炉炉中的应力腐蚀开裂。

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.
