Fire-resistant cotton tunnel kiln tunnel kiln refractory lining cotton construction

Fire-resistant cotton tunnel kiln construction tunnel kiln refractory lining cotton lining construction tunnel kiln refractory lining construction 15,098,724,516 0531-58597690 cotton tunnel kiln is hot materials, ceramics, refractory industrial application of more modern industrial furnace, a continuous production industrial equipment. Generally along the longitudinal direction of the tunnel kiln kiln into preheating zone, firing zone and cooling zone. Fire-resistant fiber used as a warm-up, cool down with a wall lining, insulation backing firing zone. Shengyang cotton lining with refractory refractory refractory cotton material advantage is a lightweight, highly efficient thermal insulation material, compared with the conventional insulating material, it has the following advantages: fire-resistant cotton lining for low bulk density: ceramic fiber lining than light quality insulating brick 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. Fire-resistant cotton lining for heat capacity (amount of stored heat) Low: Fire-resistant cotton lining heat capacity of only light 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. Cotton for refractory lining of low thermal conductivity: Fire-resistant cotton lining in the average temperature 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. Cotton for refractory 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.
