The specific embodiment

The preparation method of the described a kind of outdoor metal colorful porcelain enamel sculpture of the embodiment of the invention may further comprise the steps:

1. moulding:, and metal body made various moulding in the described works according to one group of works of forming by various moulding such as old man, child, girl, doggies of creative design;

2. metal ingredient test, selected and casting: the cast iron enamel sculpture is to meet the enamel technology technical conditions to the material requirement of foundry goods, texture material is even, cementite is evenly distributed, total carbon is not higher than 5.5%, and sulfur content is less than 0.3%, and crystal grain requires thinner, compact structure, slag inclusion is the least possible, does not have tangible empty aperture bubble and crackle, and the thickness deviation should be less than 5; Performance requirement to foundry goods: enamel should have good flowability with foundry goods, and institutional framework must be fine and close, and graphite is tiny, defectives such as pore-free, crackle, and its chemical component weight content should meet the following requirements: total carbon: 5～5.4%; Manganese: 0.4～0.7%; Silicon: 2～2.5%; Sulphur:＜0.1%; Phosphorus:＜0.6%;

3. ground-coat enamel type test, selected and spraying: in the actual fabrication, the situation of foundry goods often deviation is very big, for example personage's arm neck and abdominal cavity moulding, arm and neck are solid shape substantially, and thickness is only 5～10 millimeters around the abdominal cavity, and thickness differs nearly ten times, under conventional conditions, be difficult to reach basic constant temperature, for this reason, we adopt the soft or hard ground-coat enamel to adjust way, make works integral body fire the state basically identical; The coating method of enamel: mainly contain the manual application of slip, spray, soak ward off, that electrodeposition enamelling, static spray etc. is multiple, generally waits the choose reasonable coating method according to product amounts, quality requirement, raw material, productivity ratio;

4. fire end porcelain and record data: suitable temperature and time is selected in firing according to different goods of enamel, and foundry goods enamel firing temperature is generally 680～900 ℃, and the time is 5～75 minutes;

5. spray colored glaze: identical with the coating method of base enamel: mainly contain the manual application of slip, spray, soak ward off, that electrodeposition enamelling, static spray etc. is multiple, generally waits the choose reasonable coating method according to product amounts, quality requirement, raw material, productivity ratio; The basis of enamel: enamel is the frit frit of definite composition to be pulverized with additive be mixed and made into glaze slip, the coating that forms in the metal surface of blackening then, the rich and varied of natural mineral matter makes us too plenty for the eye to take it all in, therefore, the cast iron enamel sculpture will obtain same riotous with colour colored glaze;

6. the enamel colored glaze is fired and record data: the firing of enamel: select suitable temperature and time according to different goods, foundry goods enamel firing temperature is generally 740～880 ℃, and the time is 5～60 minutes;

7. on-the-spot the installation: large-scale sculpture often needs that sculpture is divided into several portions to be processed, and assemble at the scene of transporting to again, and the method for assembling has: the prefabricated suit of moulding, screw, nut structure method; Welding outer cover cast iron enamel gadget method; Inner accurately steelframe, cast iron enamel sculpture parts cross structure overlap joint.

This large-scale cast iron sculpture can produce the casting flaw that a lot of conventional cast iron products seldom occur in casting: as sand holes, and misrun, crackle, slag inclusion, short texture, cavity and bubble, this has added more difficulty for the enamel processing of cast iron.In this case, fill up smooth smooth in defective local reconditioning with iron embryo material for repairing cream, enamel slip and the effectively combination of material for repairing cream, bonding firmly, thereby improved the presentation quality of cast iron enamel sculpture greatly.
