Instructions of Refractory Bricks in Different Environments

Writer:WillSource:Original Number of visits: Date:6/20/2018

SIJIHUO REFRACTORY has been specialized in providing professionla solutions of refractory lining materials for various of industrial furnaces, such as blast furnaces, hot blast stoves,  cupola furnace, aluminium melting furnace, metallurgical steel systems, heating furnaces, and non-ferrous metal melting furnace, Sodium silicate furnace, chimney etc.

So our enterprise has the duty to help and assist more industrial construction teams to improve and develop the appliction of refractory materials.

Before constructing furnace linings,considering to maximize the refractory brick or castable refractory cement or mortar's characters, we have to take some necessary measures accoring to different construction atmosphere or temperatures in different seasons.

In summer, try to arrange the construction of refractory bricks in the morning or evening.After pouring,cover the masonry with curtains and cool it with water.

In winter, winter construction technical measures must be taken.The airtight ,wind resistance , heating and warmth-preserving measure should be taken to maintain the temperature of the lining above 5℃。

In winter, the dry materials should be stored in a warm house and mixed with hot water.The temperature of the mixture should be kept above 10℃。It in not necessary to add other chemical coagulant or anti-freeze agent. When the construction is conducted in the furnace ,sonstrut the insulation layer first to improve the ability to resist freezing.After construction, the masony shoule be covered with plastic sheeting and dry grass. For newly constructed furnaces,its insulation time shoule not be less than 10 days.Avoid exposing the masonry to the cold atmosphere.

In rainy days , construction shoule be conducted indoor. All materials , tools ,workplace and masonry shoule be rainproof.For the uncompleted furnaces ,the roof should be covered and the holes should be blocked.For the completed furnaces,the upper air interfaces should be closed and the ground preforms shoule be blocked up and capped to avoid being socked in water.

When the environment temperature is above 30 ℃ ,it can be thought as summer construction.The temperature of water and materials should be under 30℃。The materials exposed to the hot sun should be coolded before use.
