Embodiment Construction
[0012] A kind of processing method of special valve material for chlorine gas, the steps are as follows:
[0013] 1. Melting equipment and raw materials
[0014] Adopt IT intermediate frequency furnace, low S, low P pig iron, in addition, it is necessary to strictly control the impurity content in the charge: Al<0.03%, Ti<0.04%, and the rest of the charge is derusted;
[0015] 2. Melting process
[0016] Feeding sequence: first put pig iron, scrap steel, and recycled materials into the furnace for heating, and then add ferroalloy, silicon, and manganese after melting; the content of each main element is: C3~7%, Si8~26%, Mn5~10%.
[0017] Melting temperature: 1480-1520°C, melting time: 45-90 minutes.
[0018] Spheroidization and inoculation treatment temperature: 1450~1480℃.
[0019] 3. Pouring process
[0020] Pouring temperature: 1380 ~ 1420 ℃, depending on the size of the workpiece, the pouring speed is based on the principle of fast pouring, the weight of a single piece...
