Ceramic fiber insulation backing soaking furnace

Ceramic fiber insulation backing soaking furnace soaking furnace insulation ceramic fiber ceramic fiber backing soaking furnace insulation backing 15098724516 0531-58597690 soaking furnace is heated ingot blooming mill furnace, soaking furnace before rolling ingot heating and soaking into the rolling process the required temperature. Soaking pit furnace is shaped ingot heating temperature of 1200-1250 ℃, the furnace operating temperature up to 1350-1400 ℃, the case of thermal furnace periodic system. Traditional soaking furnace are used bricks masonry. Brick wall with a lower portion of the middle of the furnace, and the furnace hearth walls with high alumina brick, magnesia brick masonry hearth is also useful, mobile lid with shaped brick masonry. Since unshaped refractory materials are widely used, soaking furnace has been gradually replaced with castable refractory brick masonry, and achieved good results. Permanent cold furnace wall insulation refractory fibers can be used soaking furnace lid sealing groove activity (replace the original sand seal groove) and heat insulation chamber lining the walls. Shengyang with ceramic fiber insulation backing advantage refractory ceramic fiber material is a lightweight, highly efficient thermal insulation material, compared with the conventional insulating material, it has the following advantages: low bulk density ceramic fiber for lining: ceramic fiber lining ratio lightweight insulation tiles lining lighter than 75% lighter than the light casting material lining 90% to 95%. Such as the use of steel fiber lining can greatly reduce the load of the furnace, to extend the service life of the furnace. Ceramic fiber for lining heat capacity (amount of stored heat) Low: heat capacity of only lightweight ceramic fiber lining heat and light castable lining l / 10, while the weight is proportional to the heat capacity of the lining material and lining. Speed ??low heat capacity means the furnace in the reciprocal operation absorbed less heat while warming speeds up, greatly reducing the furnace operating control of energy consumption, especially for start furnace furnace shutdown play a very significant energy-saving effect. Ceramic fiber for low thermal conductivity lining: ceramic fiber lining in the average temperature of 400 ℃, the thermal conductivity of less than 0.1w / mk, the average is less than 600 ℃, 0.l5 w / mk, on average less than 1000 ℃ 0.25w / mk, approximately lightweight clay brick l / 8, the light resistant lining l / 10, adiabatic effect is remarkable. Ceramic fiber for lining construction is simple: the construction process without leaving in expansion joints, construction workers through basic training to job, little effect on the lining construction technology insulating effect of the factors.
