Abstract
A device for maintaining efficient a tapping channel of a furnace for the production of metal, includes a bearing structure and a mobile support means associated with the bearing structure. An operating arm is associated with the support means and terminally provided with a rod. A linear positioner is configured to move the support means along an elongation axis. A corresponding method for maintaining efficient a tapping channel of a furnace for the production of metal is also provided.
Claims14
A device for maintaining efficient a tapping channel, having a substantially vertical axis, of a furnace for the production of metal, comprising a bearing structure with which there are associated support means with which there is associated a preferably L-shaped operating arm with which there is terminally associated a rod configured to mechanically free said tapping channel, and optionally to heat and/or oxy-fuel cut an occluding material that blocks said tapping channel, and a linear positioner configured to move said support means along an elongation axis, wherein the device comprises movement means integral with said support means and associated with both said bearing structure and also with said operating arm which is moved sliding on said first support means along said elongation axis in a manner coordinated with and consequent to the movement of said first support means.
A method for maintaining efficient a tapping channel, having a substantially vertical axis, of a furnace for the production of metal, comprising:
- an alignment step, in which a bearing structure is positioned with respect to said furnace in order to align a rod of a preferably L-shaped operating arm with said tapping channel,
- an active movement step, in which support means associated in a mobile manner with said bearing structure and supporting said operating arm are moved by means of a linear positioner along an elongation axis in a first direction causing, by means of movement means which are integral with said support means and are associated with both said bearing structure and also with said operating arm, a coordinated movement of said operating arm in the same first direction,
- wherein said method comprises a subsequent active or passive movement step in which said support means move in an opposite second direction and said movement means move said operating arm sliding on said first support means along said elongation axis in the same second direction of movement.
