The beneficial effects of the present invention are:
The first filter screen is arranged in the present invention in sprue cup, to carry out primary filtration to the molten steel poured into, plays well
Pushing off the slag effect, and the filter screen relative to mean level setting, the first filter screen more easy cleaning, the second filter screen also functions to secondary
Filtrate steel impurities in water is played the role of in the setting of the effect of filtering, the first filter screen and the second filter screen, helps to reduce casting
Part generates slag blister defect, it helps so that the molten steel passed through becomes current stabilization state, reduces molten steel volume gas, reduces casting and generate gas
Hole defect；The bottom of the admission chamber of sprue cup is arc, and for funnel shaped structure, the sprue cup of the structure makes steel
Water is not easy to splash；The bottom of the injection chamber of sprue cup can be arc, can collect the impurity such as the residue in molten steel, it helps
Reduce the generation of slag blister in casting；The side wall of the injection chamber of sprue cup is the conical surface, and is equipped with multiple third cross gates and molding box phase
Even, poring rate can be made fast, so that rapid aggregation, reduction air enter molding box and formed the molten steel in molding box from bottom to top
The defects of stomata of casting, improves the quality of casting.
