Embodiment Construction
[0044] The following is attached Figure 1-3 The application is described in further detail.
[0045] The embodiment of the present application discloses a casting process for an end cover of a paper machine.
[0046] A paper machine end cover casting process, comprising the following steps:
[0047] S1. Manufacturing molds using molding sand.
[0048] S2. Drying: drying the manufactured mold.
[0049] S3. Box matching: combine the dried molds together, and put two neutrons into the mold, so that the insertion hole 21 and the connecting pipe 22 are formed at the neutrons during subsequent casting.
[0050] S4. Smelting: Use an intermediate frequency electric furnace to smelt the prepared raw materials to form a molten metal. The raw materials are smelted at a temperature between 1600°C and 1680°C. The melting time is 1.5h to 3.5h. In this embodiment, it is specifically at 1680°C. Smelting for 2 hours, more fully smelting raw materials in a shorter time.
