Applications
BOF Vessel Gunning
Designed for the hot application of pneumatically applied monolithic refractory materials
Water-cooled boom/lance provides effective system for application in extremely hot environment
- No warping/failure of gunning lance and boom manipulator
- Best possible refractory quality delivered to targeted repair areas due to boom/lance cooling which minimizes impact of extreme heat on as-installed refractory physical properties.
- Capability to extend over 30’ to address large process vessels and maintain critical wear areas.
Controlled remotely via KT-Grant radio joystick pendant.

Applications
Remove and replace EBT/EAF taphole insert
Patented quick-change attachment system used in conjunction with KT-Grant GOM-360 Series track machines
Robust system that enables core drilling and removal of worn taphole insert.
- Average time to core drill typically under 5 minutes
Resultant smooth bore facilitates new taphole insert placement.
Taphole insert attachment (shown at left) used to install new refractory insert.
- GOM-360 boom articulation function enables exact alignment of insert prior to monolithic refractory installation

Applications
Refractory surface removal and preparation
- Passive system for refractory removal as compared to hydraulic/pneumatic hammering
- Preferred method for repairing/maintaining blast furnace casthouse runner systems
- Rotary profiling action removes only friable/oxidized refractory, leaving good material intact
- Surface preparation promotes improved refractory adhesion to applied substrate
- Particularly effective where either shotcrete or gunnite maintenance practice is used.
- Proven system for reducing refractory consumption and overall refractory cost/ton due to improved efficiencies in refractory removal and preparation practices
- Used in conjunction with KT-Grant GOM-360 track machines, operators can realize measurable gains in both productivity (via reduced downtime) and refractory cost (reduced consumption).

Applications
EAF Slag Door Maintenance
- Single-stage and two-stage boom available to accommodate shop floor requirements
- Simple, proven design to maintain EAF tunnel and door sill
- Push force of 39,260 lbs and pull force of 25,000 lbs ensures that scrap is pushed well into the furnace and slag accretions are removed
- Permanently mounted to shop floor and parked either in vertical or horizontal position
- Wired or wireless joystick controls can be operated from EAF pulpit
- Designed for ease of maintenance with easy access to all critical components
- No rails/floor maintenance required or wear and tear to mobile equipment
- The most cost-effective option available for EAF slag door maintenance
- 15 units in operation throughout NAFTA

Applications
EAF Lining Removal
- Equipment is staged on top of the electric furnace
- Minimal cooling required prior to commencing refractory tear-out. Substantial time savings realized.
- Accommodates furnace shell diameter range of 10.0 ft. to 35.0 ft. (3.05M to 10.68M).
- Boom swing/rotation is 360° and can telescope to accommodate all areas of the furnace.
- 1,000ft/lb class hydraulic hammer attachment to ensure efficient de-lining process.
- 150 ton furnace lining can be removed in as little as 4 to 6 hours with two-man operation.
- Tethered cable pendant control (50 ft.) permits operator freedom to position for most advantageous sight lines.
- Wireless radio control option available

Applications
Slag Skimming in Hot Metal Ladles
- Telescopic boom design, equipped with skimmer paddle
- Ability to move in vertical plane to control depth of paddle and optimize yield
- Permanently mounted system that provides versatility regarding customer logistics and practice
- Operator controls can be located per customer request to provide safe and convenient operation of the machine
- Optional air-conditioned operator cab can be included to permit integrated system and offer safe alternative for machine operation
- Various paddle types/designs available to suit operation
- KT-Grant offers a nitrogen bubbler lance system to provide additional efficiency/yield enhancement to the skimming operation

Applications
Reheat Furnace Hearth/Subhearth Removal
- Remote controlled, automated refractory demolition and removal
- Small footprint for operation in limited access/confined space applications
- 1,000ft/lb class hammer – exerts force required to quickly and efficiently remove high-performance, high-density working hearth materials (high-alumina/spinel reinforced/etc).
- Facilitate removal of alloy skid rails (where used)
- Minimize personnel in furnace during potentially dangerous demolition work.

• Typically 2-4 KT-Grant operators required.
• Eliminate large labor force exposure to slip/trip/fall hazards, respirable crystalline silica, back injuries, etc.
