Abstract: Presented are an insulation brick and the method of using an insulation brick to create a thermal lining. A set of corrugations are formed into a sidewall of the brick to increase the thermal insulation. A first end of the insulation brick has a convex portion while the second end of the insulation brick has a convex portion. This allows a first insulation brick to mate with another brick in an end to end configuration.

Abstract: The invention mainly relates to a process for recycling blast furnace gas in which at least one portion of the gases resulting from the blast furnace undergo a CO2 purification step so as to create a CO-rich gas which is reinjected at a first top injection point located above the base of the blast furnace at a temperature between 700° C. and 1000° C. through a top injection line, and at a second bottom injection point at the base of the blast furnace at a temperature between 1000° C. and 1300° C. through a bottom injection line, in which the gases from the bottom and top injection lines are heated by means of heaters from which the gases emerge at a temperature between 1000° C. and 1300° C. The process of the invention is essentially characterized in that a portion of the CO-rich gas (18) exiting the purification step is directly introduced into the top injection line (21) via a cold gas injection line (35) in order to obtain a temperature between 700° C. and 1000° C.

Abstract: A fire resistant steel structure (10) comprises a steel beam (14) for receiving a vertical load and a support structure for supporting the horizontal beam (14) at two horizontally spaced locations. At least one fire-resistant tension member (30) has its ends (32, 32?) anchored outside the steel beam (14) in the support structure. It is arranged relative to the steel beam (14) in such a way that when the steel beam (14) is overheated and yields under the vertical load in case of severe fire conditions, it rests on the at least one fire-resistant tension member (30) and is vertically supported by the latter.
