Embodiment
[0033] A kind of high temperature resistant foam sprue cup and its processing technology of the present embodiment, such as Figure 1 to Figure 3 As shown, the sprue cup 1 is made of foam and includes a sprue cup body 11 and a sprue channel 12 connected thereunder. The diameter of the sprue cup 1 gradually decreases from top to bottom. The sprue cup body 11 The cross-section of the sprue cup body 11 is asymmetrically elliptical, and the cross-sectional area of the sprue cup body 11 is larger than that of the gate channel 12, and the gate channel 12 is circular or square; The entrance of the cup 1 is pasted with a cloth film seal 3, and the outer wall of the sprue cup 1 is coated with a high temperature resistant layer 2.
[0034] The shape design of the main body 11 of the sprue cup is compared with the sprue cup 1 of the positive taper. When the molten iron is poured, it can prevent the molten iron from spinning and splashing out in the sprue cup 1, causing harm to the work...
