Abstract:

The masonary or refractory material employed in the lining of blast furnaces has to be demolished, torn out, reconditioned, or replaced periodically, due to wear and deterioration of such material and the subject invention involves improved equipment or apparatus with respect to removing or delining this material. More particularly, the equipment includes a lower rotatable oblong carriage supporting a mounting adjacent one extremity of the carriage which carries an articulated structure provided with a reciprocable tool for disintegrating the liner material, an upper support for the carriage, cable means extending from the support for connection with means for suspending the equipment in the furnace, and power operated cables extending from the support for connection with means on the wall of the furnace whereby the equipment can be controlled and stabilized by an operator on the carriage to locate the equipment on a vertical axis of the furnace or in any one of an infinite number of radial and/or circumferential positions with respect thereto so as to facilitate locating the tool for efficient operation against the refractory liner in the furnace. The cable means and cables are extensible and extend only from the support so that they will not interfere with the rotation of the carriage and/or operation of the articulated structure and tool.
