Abstract
The utility model discloses a pulvis ferri groove brick, which is used for a casting system of a water cooling type ball milling cast iron pipe casting machine. The pulvis ferri groove brick comprises a slide type bottom surface and side walls arranged at both sides of the bottom surface, wherein the slide type bottom surface is formed by tangential arrangement of an upper circular arc surface and a lower circular arc surface, the upper end of the upper circular arc surface is also provided with a circular arc transition technological inclined surface used for preventing cold shots from splashing, and support ribs are also arranged on the back side of the pulvis ferri groove brick and are positioned at the lower part of the molten iron casting part. When the utility model is adopted, the molten iron can not easily splash, and in addition, the service life is long.
Description
Technical field
The utility model relates to a kind of iron low water brick, is used for the running gate system of water-cooling type nodular cast iron pipe casting machine.
Background technology
At present, the general graphite low water brick that uses in the running gate system of water-cooling type nodular cast iron pipe casting machine.Its structure is referring to accompanying drawing 1, and the low water brick bottom surface of molten iron stream process is to add a circular arc in the middle of two straight lines.Its raw material is a graphite powder, adds high temperature adhesive then, produces approximate shape, manually is trimmed to type then before not solidifying.The shortcoming of graphite low water brick is: 1. in the manufacture process graphite particulate contaminated environment and the injury health of human body; 2. lack service time, generally use 20h; 3. its shape can not rationally satisfy the production needs, and molten iron easily produces and splashes.
The utility model content
When the technical problems to be solved in the utility model provides a kind of the cast molten iron be difficult for splashing, the iron low water brick of long service life.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of iron low water brick, it comprises the bottom surface of slide formula and is located at the bottom surface side walls that its key technology is that described slide formula bottom surface is via last arc surface and tangent the forming of following arc surface.
Further improving on above-mentioned arc surface upper end also is provided with and is used to the technology inclined-plane through arc transition that prevents that splashings from splashing.
Further improve at the above-mentioned iron low water brick back side and be positioned at bottom, the molten iron place of pouring into and also be provided with brace rod.
Adopt the beneficial effect that technique scheme produced to be: the utility model molten iron is relative mild with the contact of iron low water, does not produce during cast and splashes; Further improve the technology inclined-plane that is provided with, can rationally avoid splashings to splash; The brace rod that is provided with can strengthen the intensity of iron low water brick; Adopt ferrous material, can increase the service life, life cycle reaches 36h.
Description of drawings
Fig. 1 is the utility model prior art constructions schematic diagram;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is a structural representation of the present utility model;
Fig. 4 is the vertical view of Fig. 3;
Wherein, arc surface is gone up in 1 representative, and 2 representatives are arc surface down, and 3 represent the ladle mouth, and 4 represent the molten iron line of flow, and 5 represent the technology inclined-plane, and 6 represent brace rod, and 7 represent sidewall.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to accompanying drawing 3 and accompanying drawing 4, the utility model is the groove shape structure of slide formula, the opening that the top molten iron pours into the place is big, the opening of bottom molten iron outflow place is less, both sides, ground in the slide formula are provided with sidewall 7, slide formula bottom surface is by two sections tangent forming of circular arc dovetail, and it is mild relatively that molten iron waters fashionable contact like this, and molten iron does not produce and splashes.Also designing in the upper end of last arc surface 1 has increased by a segment process inclined-plane 5, and this technology inclined-plane 5 and last arc surface 1 can effectively prevent like this that through arc transition splashings from splashing.At the back side of this iron low water brick and be positioned at molten iron and pour into the position and be provided with brace rod 6, can strengthen its intensity.The utility model adopts the QT400 material to make, and service life is longer, can reduce cost.
Claims (3)
1. iron low water brick, it comprises the bottom surface of slide formula and be located at bottom surface side walls (7), it is characterized in that: described slide formula bottom surface is via last arc surface (1) and tangent the forming of following arc surface (2).
2. iron low water brick according to claim 1 is characterized in that: arc surface (1) upper end also is provided with and is used to the technology inclined-plane (5) through arc transition that prevents that splashings from splashing on described.
3. iron low water brick according to claim 1 and 2 is characterized in that: at the described iron low water brick back side and be positioned at bottom, the molten iron place of pouring into and also be provided with brace rod (6).
