| Incinerator / Crematorium |
 |
The usual problems encountered are those of thermal shock and slag formation. A coating of Nonvit at 2 to 3 mm minimises the life of the refreactory lining. |
| Aluminium Melting / Holding Furnace (1) |
| The refractory lining is typically a high alumina castable which is subject to the destructive effects of high temperature and molten aluminium. The frequency of repairs is reduced by a lining of 3 to 6 mm Nonvit. |
 |
| Aluminium Melting Furnace (2) |
 |
3 mm of Nonvit will seal the refractory against the leaching effects of molten aluminium. 6mm is used to line the connencting channel. |
| Glass Melting Furnace |
Nonvit is used for patching cracks, crevics and joints on the crown. It may be applied by trowelling, ramming, tamping, pouring or caulking. |
 |
| Nose Arch in Field Erected Water Tube Boilers |
 |
This part of the boiler is subjected to both hugh tempretures and slag attack from the products of combustion. A coating of 2 to 3 mm of Nonvit on the refractory sirface will minimise the effects of spalling, slagging and abrasion. |
|
Suspended Monolithic Roof of Field Erected Boiler Usiong Both Oil and Solid Fuel A coating of 2 to 3 mm Furnascote Nonvit applied to the refractory surface increases it resistance to the destructive effects of spalling, slagging, chemical attack and erosion. |
 |
| Induction Furnace |
 |
The rammed lining is subjected to chemical attack by molten metal and to cracking and spalling from thermal shock, 1 - 3 mm of Furnascote Nonvit will reduce these effects, extend the life of the furnace and improve the quality of the processed metal. |
| Reheating Furnace |
| A thin coat of 1 to 2 mm Nonvit reduces the adhesion of slags to the floor. The Nonvit makes it easier to remove slag when cleaning. |
 |
| Receivers |
 |
A coating of 2 to 3 mm Furnascote Nonvit on the walls and lips of receivers will prolong the life of the lining. |
| Small Ladles |
Hand ladles lined with mouldable refractory can be coated with 2 to 3 mm Nonvit to increase the number of heats and increase production life. |
 |
| Crucible Furnace |
 |
Frequent repairs are necessary due to the damaging effects of high temperature and thermal shock. These conditions cause cracking of the refractory lining and heat losses. Nonvit coated at 2 to 3mm , will eliminate or minimise the problem. |
| Tunnel Kilns |
| Thermal shock and slag formation are common problems with high refractory wear around burner ports. Salt glazes are corrosive to conventional refractories. A coating of Furnascote Nonvit at 2 to 3 mm mininises the destructive effects of combustion, glazing and thermal shock. Slag removal is easier and reject rates reduced. |
 |
| Tundish In Continuous Casting |
 |
Frequent repairs and shutdowns are encountered due to the effects of high temperature and thermal shock. A thin coat of 2 to 3 mm Nonvit prolongs the life of the refractory lining. |
| Soaking Pits |
| High temperature and thermal shock lead to spalling of the refractory lining. These effects and hence the cost of maintenance can be reduced by application of 2 to 3 mm Nonvit. |
 |
| Electric Arc Furnace |
 |
The centre section of the roof is made of either castable or plastic refractory. A coating of 2 to 3 mm of Nonvit will minimise the destructive effect of high temperature and thermal shock, prolonging the life of the refractory. |
| Baffles In Water Tube Boilers |
| A thin coat of 1 to 2 mm of Nonvit on the baffles prevents or minimises the effects of spalling, reduces the adhesion of slag and ensures a gas tight surface. |
 |
| Watertube Oil Fired Power Boiler |
 |
The burner throat is subjected to intense wear and tear due to the effects of high temperature, slagging, chemical attack, erosion and thermal shock. A coating of 2 to 3 mm of Nonvit resists these combined effects on the refractory lining. A coating of 1 to 2 mm on the walls and floors minimises the adhesion of slags and helps in prolonging the life of the refractory life. |
| Firetube Package Type Boilers For Processing |
| High temperature, thermal shock, slags, chemical attack and erosion have a devastating effect on the parts exposed to heat, particularly the burner throat. A 2 to 3 mm coating of Furnascote Nonvit on the burner throat and a 1 to 2 mm coating the rear and front baffles will extend the life of the refractory lining. |
