Core Function

Replace manual work, accurately throw bagged refractory repair materials to damaged converter lining under high temperature, conduct rapid hot repairing, extend furnace service life, reduce refractory consumption and operational risks.

Main Functions

1. Core hot repairing at high temperature

   Repair without cooling after steel tapping and slag dumping, furnace temperature up to 1600℃. Avoid shutdown for cold maintenance and improve operational efficiency.

2. Accurate throwing for key areas

   Throwing range: 10-15 meters. Precisely reach hard-to-access positions including trunnion, molten pool, slag line and furnace wall. Ensure uniform and firm bonding of repair materials.

3. Cost efficiency & labor reduction

   Working efficiency 3-5 times higher than manual operation, greatly shorten repairing time. Remote control and fire shield prevent high temperature burn injury. Precise feeding cuts refractory waste and consumption per ton of steel.

4. Prolong converter service life

   Timely fix lining erosion and peeling to avoid furnace burnout. Furnace campaign life reaches 5000-10000 heats.

Typical Application Scenarios

1. Daily hot maintenance of steelmaking converter

   Operate during short idle period after tapping and deslagging. Service areas: trunnion zone, slag line, molten pool, furnace cap and furnace wall. Applicable materials: 2.5-3kg per bag magnesia-carbon and high-alumina hot repair material.

2. Reinforcement before intermediate & major overhaul

   Repair severely eroded lining in late service period, cut unplanned downtime and reserve overhaul time.

3. Repair after special steel smelting

   Recover slag line and molten pool after producing high-carbon steel, stainless steel and other easily corroded steel grades.

4. Manual replacement for small converter & intermediate frequency furnace

   Flexible mobile device suitable for 10-50t small converters and intermediate frequency furnaces, eliminating high risks and low efficiency of manual operation.
