RAMMING MASS FOR THE REFRACTORY COATING OF A METALLURGICAL VESSEL, METHOD FOR IMPLEMENTING SAME AND METALLURGICAL VESSEL, IN PARTICULAR A BLAST FURNACE, COMPRISING A COATING USING SAID RAMMING MASS |
摘要 |
A ramming mass for the block lining of at least some of the refractory elements of a refractory lining of a metallurgical vessel such as a blast furnace, said ramming mass being composed of a mixture of a granular phase and a binder phase, wherein the granular phase and/or binder comprises at least one component having a microporous structure or capable of forming a microporous structure by firing during the blast furnace campaign.;The ramming mass is in particular intended for forming the joint between two concentric annular assemblies forming a side wall of the vessel or between a lower part of an inner annular assembly and the periphery of one or more refractory layers forming the floor of the vessel. |

1. A ramming mass for producing hot joints when block lining refractory elements of a refractory lining of a metallurgical vessel such as a blast furnace, the ramming mass comprising:
a granular phase comprising carbon or carbon-based granules having a microporous structure; and a binder comprising at least one component based on tar or polymerising resin, and an additive composed of metallic silicon powder, capable of developing a microporous structure having an average pore size of 2 μm or less on firing at high temperature, by the formation of whiskers which develop across pores of hardened tarry or polymerised material. |
