[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0025] Example 1: A high-grade nickel matte slow cooling device, see Figures 1 to 4 , including a nickel mold body 1, a card frame A2, a card frame B3 and a foot 5;

[0026] The card frame A2 is sleeved on the top outer wall of the nickel mold body 1; the card frame B3 is sleeved on the bottom outer wall of the nickel mold body 1; wherein, an aluminum silicate wool pad A4 is arranged between the card frame A2 and the card frame B3, the aluminum silicate wool pad A4 is wrapped, and the wrapping of the aluminum silicate wool pad A4 is glued; two base feet 5 are symmetrically welded to the bottom side of the nickel mold body 1, and the base feet 5 contact the ground to support the nickel mold body 1.

[0027] The utility model has the advantage of being easy to install or disassemble the aluminum silicate wool pad A4 by setting the card frame A2, the card frame B3 and the aluminum silicate wool pad A4, and slowing down the cooling speed of high-grade nickel matte by using the aluminum silicate wool pad A4, thereby solving the problem that the nickel mold has no thermal insulation material and is made of heat-resistant cast iron, resulting in too fast cooling speed, which affects the quality of high-grade nickel matte.

[0028] Specifically, the cross-sections of the card frames A2 and B3 are L-shaped, and the upper and lower ends of the aluminum silicate wool pad A4 are respectively clamped in the card frames A2 and B3, so that the aluminum silicate wool pad A4 will not fall off when pouring high nickel matte.

[0030] The utility model has the advantage of providing the aluminum silicate wool pad B7, thereby also performing heat preservation at the top closed part, and further slowing down the slow cooling speed of the high nickel matte.

[0031] Furthermore, the four sides of the bottom of the aluminum silicate wool pad B7 are set to be arc-shaped edges 701, and the arc-shaped edges 701 are set inward; when the aluminum silicate wool pad B7 is inserted into the top opening of the nickel mold body 1, the setting of the arc-shaped edges 701 makes it easier to insert the aluminum silicate wool pad B7.
