Energy-saving measures for cast iron pipe fittings
The increase of enthalpy of ductile iron pipe in the annealing furnace is mainly determined by the temperature at which the ductile iron pipe is heated in the furnace and the temperature at which the ductile iron pipe is put into the furnace.
A, the reasonable formulation of different annealing temperature of the Carbon Steel Pipe long nipples diameter ball iron pipe the lower annealing temperature is, the more save fuel, but the ball iron pipe annealing process requires annealing furnace heating furnace temperature is 1050 ~ 1100 ℃, the heat preservation period of furnace temperature is 960 ~ 1000 ℃, in order to ensure that the ball iron pipe annealing quality, under the condition of the technology allowed, should be carried out in accordance with the lower limit of temperature control, especially in small diameter pipe can decrease the heating period of furnace temperature.
In the process of production, making full use of waste heat of materials at the end of the previous process is an important way to save energy. According to the theoretical calculation, the ball iron pipe heated to 1000 ℃, 600 ℃ and 25 ℃ charging into the 320000 kj, lower than the t tube energy consumption can save about 20 m3 coke oven gas or heavy oil 8 kg. The annealing capacity of cast pipe company's annealing furnace is about twice that of the existing centrifuge. During annealing furnace pipe online guarantee under the premise of continuous annealing heat pipe before charging, shorten the transmission time of heat pipe, make half pipe charging temperature from ambient temperature to 600 ℃ or so. Thus, the tube heat transfer ratio and the furnace temperature are improved, and the energy saving effect is remarkable.
