Large-scale thin-wall valve body lost foam casting process

The invention relates to a large-scale thin-wall valve body lost foam casting process, comprising the following steps of: (1) pre-foaming polystyrene beads; (2) curing the polystyrene beads; (3) moulding a white mould; (4) drying the white mould; (5) assembling the white mould; (6) brushing lost foam casting fireproof coating on the surface of the obtained white mould; (7) drying the white mould coated with the coating; (8) burying a box and compacting; (9) pouring molten iron; (10) insulating heat after pouring is finished, and then opening the box; and (11) cleaning off redundant anti-deformation ribs, and polishing and levelling by adopting a grinding wheel to obtain a thin-wall valve body. According to the process disclosed by the invention, when the white mould of the valve body is moulded, a cross-shaped rib which can prevent a round hole from deforming is additionally arranged in a flange hole, stiffness of the white mould is increased, deformation can be prevented; a T-shaped rib, an I-shaped rib and a diagonal tie rib are additionally arranged in an inner cavity of a square hole after assembling and adhesive bonding, an anti-deformation rib for a square opening is additionally arranged outside the square opening, and therefore deformation of the white mould after assembling is effectively overcome. When a casting is cleaned, the anti-deformation ribs inside and outside are removed, thus deformation of a workpiece is avoided and rejection rate is reduced.
