Abstract

The utility model relates to a device sending melted metal into a ground die or a casting die and especially relates to a groove-type brick. The groove-type brick includes a slide-type bottom face and side walls arranged on two sides of the slide-type bottom face. Connection parts of the slide-type bottom face and the side faces are provided with transitional circular arcs. Inner wall faces of the two side walls are both technical inclined faces and the upper ends are both provided with arc-shaped faces. The groove-type brick provided by the utility model is formed in a single process through pouring aluminum silicon carbide and aluminum silicon carbon into a mechanical mold. The groove-type brick is accurate in size, smooth in surface, high in integral strength, good in high temperature resistance and long in service lifetime. By arranging the transitional circular arcs in the connection parts of the slide-type bottom face and the side walls and the technical inclined faces, molten iron contacts with the mold in a relatively smooth manner, so that splashing is avoided and convenience is made for cleaning since areas adhered with iron are reduced.

Description

A kind of low water brick

Technical field

The utility model relates to a kind of equipment of motlten metal being sent into ground type or casting mold, relates in particular to a kind of low water brick.

Background technology

At present, the general graphite material low water brick that uses in the running gate system of water-cooled nodular cast iron pipe, graphite material tissue looseness, low, the high temperature resistant molten iron impact of intensity are poor, and in general 16 hours service life, service life is short, changes frequent.Material and the structure of existing graphite material low water brick can not meet need of production, restriction due to graphite material self, graphite low water brick cannot mechanization production, can only be by manual sawing, punch, wear the docking of steel wire, 5-6 piece, bonding, finishing, first because the surface of manual sawing is rough and uneven in surface, geometric accuracy cannot guarantee, docks crops for rotation obvious, cause graphite products size to differ, rough surface.Secondly, due to hand-built defect, in production scene, even occur graphite low water brick to repair and could use, greatly extended the replacing time, production efficiency gives a discount greatly, moreover, graphite low water brick can cause serious graphite dust to pollute to production scene in process of production, and cannot clear up and stop, also have in transportation, storage, use, with also environment being had to obvious pollution in post processing.

Utility model content

The utility model is to solve the problem that graphite low water brick service life is short, structure can not meet need of production, provides a kind of long service life, the low water brick that molten iron does not splash.

In order to address the above problem, the utility model is achieved through the following technical solutions:

A kind of low water brick of the present utility model, comprises sliding board-type bottom surface and the sidewall of being located at both sides, sliding board-type bottom surface, and the junction of described sliding board-type bottom surface and sidewall is transition arc, and the inwall of described two side is technique inclined-plane, upper end is provided with arc surface.

Further, described low water brick is made and is formed in one by aluminium silicon carbide and aluminum silicon carbide carbon.

Compared with prior art, the beneficial effects of the utility model are: low water brick of the present utility model can be poured into a mould through machine die with aluminium silicon carbide and aluminum silicon carbide carbon and make, one-body molded, size accurate and smooth surface, bulk strength is large, heat-resisting quantity, long service life, the transition arc of sliding board-type bottom surface and the junction of sidewall and technique inclined-plane to be arranged so that sticky untouchable long-pending little and molten iron waters fashionable contact relative mild, effectively prevented that molten iron is excessive, splashings splashes, after finishing using, be easy to cleaning.

The specific embodiment

Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.

As Figure 1-5, a kind of low water brick of the present utility model, the sidewall 2 that comprises sliding board-type bottom surface 1 and be located at 1 both sides, sliding board-type bottom surface, sliding board-type bottom surface 1 is transition arc 4 with the junction of sidewall 2, the inwall of two side 2 is technique inclined-plane 3, upper end is provided with arc surface 5; Low water brick of the present utility model is poured into a mould through machine die and is made, one-body molded, size accurate and smooth surface, bulk strength is large, heat-resisting quantity, long service life, it is relatively mild that the sticky untouchable long-pending little and molten iron that the setting of transition arc 4, technique inclined-plane 3 and arc surface 5 makes waters fashionable contact, effectively prevented that molten iron is excessive, splashings splashes, after finishing using, be easy to cleaning.

The sliding board-type bottom surface 1 of a kind of low water brick of the present utility model forms by arc section is tangent, smooth like this sliding board-type bottom surface 1 is conducive to flowing of molten iron, sliding board-type bottom surface 1 is transition arc 4 with the junction of sidewall 2, the inner arc surface 41 of transition arc 4 is tangent with sliding board-type bottom surface 1 inner surface and sidewall 2 inwalls, the exterior arc surface 42 of transition arc 4 is tangent with sliding board-type bottom surface 1 outer surface and sidewall 2 outer walls, and such transition arc 4 has not only strengthened bulk strength but also sticky untouchable long-pending little, easy to clean; The low water brick of groove shape is made and is formed in one by aluminium silicon carbide and aluminum silicon carbide carbon, low water brick integral body is pressed proportion ingredient by refractory material aluminium silicon carbide and aluminum silicon carbide carbon, through stirring, cast, vibration moulding, Technology for Heating Processing forms, and its density is large, hardness is high, tension, resistance to compression, anti-folding, intensity are large, heat-resisting quantity and molten iron wash away and are greatly improved, and be 5-8 times of original graphite products life-span service life.

A kind of low water brick of the present utility model, producing, transport, store in a warehouse, use, all not producing environmental pollution with post processing, is the novel product of environmental type.The utility model has adopted mold production, each size unification of product, standard, the obstruction that uneven and seam crops for rotation produce and the problem that affects molten iron smoothness have been eliminated, solved the difficult replacing problem that differs and cause because of size, shortened the replacing time, because long replacing of life-span is no longer frequent, short utilization rate of equipment and installations and the productivity ratio that has improved user of replacing time.

A kind of low water brick of the present utility model is for the running gate system of water-cooled nodular cast iron pipe, molten iron pours into from opening general goal as shown in Figure 3 and Figure 4, pour into contact relatively mild, molten iron is narrowed down by wide, the chute connecting below the little inflow of opening, chute stretches into centrifuge far-end, and molten iron is poured in cast tube mould, complete the pouring technology of ductile iron pipe, this novel important step of forming a connecting link that plays.

The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
