Integrated Steel
KT-Grant designs and builds specialty engineered equipment for a variety of Steel Industry applications.
Vessel/Converter Maintenance
De-skull lip castings, cones, and charge hole. Precision taphole removal. Reduce furnace repair downtime. Careful material removal extends refractory life.
Blast Furnace Maintenance
Blast furnace lining is removed or descaled using remote controlled equipment operated safely from outside the furnace. Workers are no longer exposed to risk of being crushed by falling debris. Precision burden, stave, scab and lining removal is completed, saving shifts or even days of downtime.
KT-Grant’s GSM-1400 enters the hot blast stove though a dome portal and is lowered down via wench to remove all checker brick.GOM-360BDRE Series II with extended rake safely pulls all debris out of lower portal.
Casthouse Trough and Runners
Blast furnace tap hole and socket maintenance. Trough shoulder maintenance. Trough refractory removal. Iron trough rotary profiling. Gate removal/knock-out.
Slag and iron runner buildup removal. Tilter maintenance. Penstock blowpipe removal and installation. Tuyere and cooler removal and installation.
Soaking Pit Maintenance
Slag removal from pit bottom. Precision removal of coping block. Clean flue opening.
Selective and complete wall removal. Grind monolithic services using rotary grinding attachment. Careful material removal.
Extended refractory life. Reduce soaking pit repair downtime.
Iron Mixer Maintenance
Iron mixer refractory lining, iron skull and slag build up is removed using remote controlled equipment operated safely from outside the mixer.
Workers are no longer exposed to risk of being crushed by falling debris. No scaffolding required.
Clean iron mixer receiver and pouring spout. Open plug at bottom of mixer. Careful material removal extends refractory life. Monolithics are sprayed for patching.
BOF Taphole Change Out
Using a specialty engineered KTG system, the taphole is efficiently removed, and a new taphole is inserted and held in place for gunning material application. Water-cooled taphole drill system uses quick change system with GOM-360BDRE Series II.
With precision taphole removal, refractory material savings is over 50% or up to 1800 lbs. No crane or crane operator required. No damage to surround block.
Taphole removed typically in 3-5 minutes. Total taphole change out reduced to 20-30 minutes. Increased production availability gaining one additional heat per taphole change.
Ladle Maintenance
Transfer, Iron and Steel ladle maintenance, hot clean and deskull. Refractory removal.
Mid-campaign precision removal of porous plug and well block. Hot punch out of upper nozzle and well block.
RH Degasser and Snorkels
Remove icicles from snorkels. Deslag snorkels for refractory repair. Remove skulls and slag buildup from degasser.
Remove degasser tank plug. Precision material removal extends refractory life.
Tundish Refractory Removal
Efficient refractory removal and tundish deskull using the GOM-360BDRE Series II’s 30 foot vertical reach. Ensure operator safety and increase process uptime.
Slag Skimming
GSK 150/190 skimmer with extended boom. Remove slag efficiently and quickly.
Ladle skim time 3-5 minutes. Greatly reduces sulfur content.
Custom designed to fit location. Compatible with ladle tilting station or held by overhead crane.
