    （1）Casting mold is blended into as Modeling Material using silica sand, bentonite, additive and water；
    When being blended, Modeling Material chooses silica sand by mass percentage：90%th, bentonite：6.5%th, additive：1% and water： 2.5%, described silica sand is mixed by 50/100-70/140 mesh silica sands, and described bentonite is sodium bentonite and calcium base Bentonite mixtures, described additive are that α starch and dextrin are 3 by weight：2 ratio mixing；
    （2）To step（1）In manufactured casting mold dried using 150-160 DEG C of hot blast, dry 2-3h；
    （3）Semi-finished product will be poured into casting mold made of solvent metallic solution injection；
    （4）By step（3）In semi-finished product be heat-treated and polished and machining obtains finished product, and examine storage；
    The concrete operations of described heat treatment are：
    A anneals：Semi-finished product stove heat to 600-650 DEG C and is incubated blowing out after 1-2h, stove is cooled to 250-350 DEG C, then turned on Fire door continuation slow cooling is come out of the stove to 150-160 DEG C is air-cooled to room temperature；
    B is quenched：By the slow stove heat of semi-finished product after being annealed in step a to 550-600 DEG C, stove heat is to using after 620-650 DEG C again Water spray semi-finished product fast cooling；
    C is tempered：Semi-finished product after will be quenched enter stove again at room temperature and stove heat is come out of the stove to after being incubated 1-2h after 200-250 DEG C It is air-cooled to room temperature.
  5. 5. the casting technique of anti-corrosion and high strength metal valve according to claim 4, it is characterised in that the silica sand Granularity is sieved for 3-4, and dioxide-containing silica >=94% in silica sand, clay content ＜ 1%, moisture ＜ 1%.
  6. 6. the casting technique of anti-corrosion and high strength metal valve according to claim 4, it is characterised in that step（1）In Described bentonite is sodium bentonite and calcium-base bentonite by weight sodium bentonite：Calcium-base bentonite=2:3 ratio is mixed Close.
  7. 7. the casting technique of anti-corrosion and high strength metal valve according to claim 4, it is characterised in that：In step（3） Metallic solution sequentially adds pretreating agent based on barium, supplemented by lanthanum into metallic solution before being poured into a mould and nodulizer is static Perlite slag making is dispensed after 15-20min on the surface of metallic solution again to purify metallic solution and skim at once.
