How to maintain heat transfer oil furnace linings in winter
After the construction of the heat transfer oil furnace lining is completed in winter, depending on the type of refractory material used, if water curing is employed, measures must be taken to prevent freezing during winter. First, anti-freezing and insulation measures should be implemented, after which the lining layer can be covered with moisture-containing straw mats; additionally, spraying water mist or steam mist can also be used for curing purposes； If it is phosphate refractory concrete, no water curing is required; it can be cured using the low temperature of the furnace heating process instead.
Lining adhesives are divided into air-setting and water-setting types. Air-setting adhesives, such as phosphates, contain little moisture; therefore, the lining can be placed without drying in an oven. Water-setting adhesives, such as various types of cement, contain more moisture, and temperatures below the freezing point of water can damage the lining, requiring curing – ideally by drying it in an oven or by raising the ambient temperature
Drying the furnace over winter is the responsibility of the manufacturer.
It is advisable to avoid building stoves in winter, especially in the north
How to maintain heat transfer oil furnace linings in winter: Measures must be taken to keep the maintenance temperature above 5 degrees Celsius, and the furnace should be dried out in a timely manner according to the instructions provided for the lining material. Otherwise, it will affect the quality of the furnace lining.
Check what the lining is; if necessary, preheat the furnace early
The furnace should be dried before winter, and a certain temperature should be maintained inside it.
