Abstract
A method of densification of refractory material in a gap between a tap hole sleeve of a furnace and a surround block of the furnace, the surround block surrounding the tap hole sleeve, the method comprising, includes positioning a tool in the gap, the tool including a support having opposing surfaces and a sidewall connecting the opposing surfaces, the opposing surfaces having an arcuate shape, a plurality of elongated members extending from one of the opposing surfaces, and a connector arranged on the other of the opposing surfaces. The gap is filled with dry material, and vibration is applied to the tool to densify the dry material.

A method of densification of refractory material in a gap between a tap hole sleeve of a furnace and a surround block of the furnace, the surround block surrounding the tap hole sleeve, the method comprising:
- positioning a tool in the gap, the tool including a support having opposing surfaces and a sidewall connecting the opposing surfaces, the opposing surfaces having an arcuate shape and defining an arc length, the opposing surfaces extending from a first end of the sidewall located at a first point along the arc length to a second end of the sidewall located at a second point along the arc length spaced from the first end, a plurality of elongated members extending from one of the opposing surfaces, and a connector arranged on the other of the opposing surfaces;
- filing the gap with dry material;
- and
- applying vibration to the connector to densify the dry material.
A tool for densification of refractory material in a tap-hole of a furnace, the tool configured to be positioned in a gap between a tap hole sleeve of a furnace and a surrounding block of the furnace, comprising:
- a support having opposing surfaces and a sidewall connecting the opposing surfaces, the opposing surfaces having an arcuate shape and defining an arc length, the opposing surfaces extending from a first end of the sidewall located at a first point along the arc length to a second end of the sidewall located at a second point along the arc length spaced from the first end, a plurality of elongated members extending from one of the opposing surfaces;
- and a connector arranged on the other of the opposing surfaces, the connector comprising a fastener configured to selectively and fixedly couple the connector to a vibrating member.
