Product Description

Magnesia Based Gunning Mix, Factory Direct Refractory Gunning Mass for EAF, BOF, Ladle Slag Line Hot Repair

Low Rebound Magnesia Based Gunning Mix, High Adhesion MgO Gunning Mass for EAF BOF Ladle Hot Repair Refractory

Keywords: low rebound magnesia gunning mix, high adhesion gunning mass, magnesia based gunning mix, slag resistant refractory gunning mix, electric arc furnace repair material, converter lining gunning mix, steel ladle gunning refractory

Description: This magnesia based gunning mix is produced in our own refractory plant. We select sintered magnesia with special binder formula to get low rebound and strong hot adhesion. It works well for hot repair of EAF bank, slag door, BOF slag line and ladle slag zone, effectively cut furnace downtime. We supply different MgO grades (85%~95%), phosphate bonded / phosphate free options. Free sample available for your lab test.

Magnesium gunning material is a non-burning refractory material with magnesium oxide (MgO) as the main chemical component. It is mainly used for rapid repair and repair of local damage to high-temperature industrial furnace linings (especially steelmaking furnaces) to extend the service life of the furnace lining.

Magnesia gunning mixes QB series are made from magnesia or magnesia together with magnesia-dolomite clinker. With the addition of compound binder, they are produced as per the optimized grain sizing. The products have the properties of high adhesive strength and good resistance to erosion and abrasion. QB-1 is mainly used for the maintenance of converter trunnion areas, QB-3 mainly for slag line and hot spots of UHP EAF and QB-5/QB-6 mainly for the snorkels of RH degasser. In order to supply a full set of refractory materials, our company has developed a series of monolithics for magnesia-dolomite and magnesia-dolomite-carbon lining, Such as QSY-1, QTC-1-and QDY-1, etc. They are used respectively as plastic mix, backfiling mix and ramming mix. This series of products are ceramic bonded under high temperature featured with high sintered strength and good integrity.

Application scenarios of magnesium gunning materials

*Converter: The large spray gun repairs the charging side, trunnion area, around the tap hole and the slag line position.
*Electric arc furnace (EAF): Repair of furnace wall hot spot area, slag line area, furnace bottom and tap hole.
*Ladle & Tundish: Repair of slag line layer and partially damaged refractory brick surface.
*Heating furnace and iron mixing furnace: Reinforced by lining bricks that are washed away and peeled off by molten slag and molten metal.
Magnesia ramming mix QD-1 and Q-2 are made from magnesia and synthetic magnesia-dolomite clinker to give good resistance to erosion and abrasion. They are mainly used for EAF bottom by dry installation. QD-3 is made from magnesia with chemical binder, the ceramic bonding is formed during the hardening process. It has good resistance to erosion and abrasion and mainly used in the bottom of metallurgical furnace and as filing materials for lining. 5-7% water is to be added during the installa

QD-6 is made from sintered magnesia and fused magnesia featured with high temperature performance and god resistance to corrosion and abrasion. It is mainly used for the metallurgical furnace in the bottom, lip ring and tap hole. QDK-18 is made from magnesia, chromite and synthetic magnesia-chrome clinker featured with good resistance to corrosion from low-alkalinity slag. It has excellent resistance to low basicity slag due to the compound spinels in it. It s mainly used in the bottom of RH
Magnesia mortar In order to satisfy the installation requirements, a series of mortars is made from raw materials of different qualities with the addition of proper binder. These mortars include magnesia based QN-1, QN-2, magnesia-carbon based QN-3, alumina-magnesia-carbon based QN-4, magnesia-chrome based QN-5 and magnesia-alumina based QN-6. This series of mortars, suitable for the installation of all kinds of basic bricks, has good adhesive and sintering strength with a setting time about 12
