Abstract

The utility model discloses a die for producing a lattice brick used for a hot-blast stove. The die consists of a die casing, edge cores, angle cores, core strips, a hole core and a base plate, wherein six inner walls of the die casing are respectively provided with the core strips which take the shape of a five truncated pyramid; two sides of the core strips are provided with the edge cores; inner angles of the die casing are provided with the angle cores which are tightly connected with the edge cores; the hole core is arranged in a reserved hole of a compression platform of the die casing; and the base plate is sheathed on the hole core and arranged at the bottom of a die cavity. By using the die for producing the lattice brick used for the hot-blast stove, not only is the dimensional accuracy of a raw brick ensured, but also the service life of the die is prolonged, the cost is reduced and the yield is improved.

Description

The hot-blast stove mould of checker brick

Technical field

The utility model relates to a kind of hot-blast stove mould with checker brick, relate in particular to a kind of by die sleeve, limit core, angle core, core bar, the checker brick mould that Kong Xin and base plate are formed.

Background technology

Hot-blast stove is one of capital equipment during blast furnace ironmaking is produced, and checker brick then are the important heat-exchanging parts of hot-blast stove, and the design of the service life of hot-blast stove and the thermal efficiency and checker brick is closely related.Checker brick are owing to work under the condition of high temperature for a long time, the brick body is subjected to certain pressure and the softening gradually plastic deformation that produced, intensity declines to a great extent, serious even the brick body is destroyed, thereby caused the integral body of body of heater to damage, so the accuracy of checker brick size have a significant impact to the heat-exchange capacity of hot-blast stove.Producing the used mould of checker brick in the past is by die sleeve, six side plates, and Kong Xin and base plate are formed, this mould is in use because briquetting pressure is big, and the pressurized of six side plates is unbalanced, makes the overtired wearing and tearing of die sleeve form rough weak point, when six asynchronous replacings of side plate, will cause the adobe scale error, and the side plate replacing time is long, complex procedures, and this brings difficulty in the time of not only can giving brickwork, and can strengthen production cost, production efficiency reduces.

The utility model content

The technical problem that the utility model solves provides the production mould of a kind of hot-blast stove with checker brick, because it is more convenient that the novelty of stencil design makes the mould use in the mould, not only guaranteed the appearance and size of adobe, and saved the template replacement time, effectively improve production output, saved production cost.

In order to solve the problems of the technologies described above, the utility model checker brick production mould, by die sleeve, the limit core, the angle core, the core bar, Kong Xin and base plate are formed.On six inwalls of die sleeve, be respectively equipped with the core bar of pentagonal pyramid platform, be provided with the limit core in the both sides of core bar, interior angle place at die sleeve is provided with the angle core, the angle core closely is connected with the limit core, limit core, angle core and core bar have replaced original side plate, Kong Xin is contained in the preformed hole that die sleeve presented a theatrical performance as the last item on a programme, and base plate is enclosed within and places the die cavity bottom on the Kong Xin.

The side plate degree of wear difference of original mould when needs are changed one side or a few limit, causes adobe profile defective easily, and changes complex procedures, needs the time longer.Now by the limit core, the angle core, three kinds of cores that have tapering of core bar have been replaced original side plate, when the limit core, after angle core and core bar wore and tore, the core replacing that only needs to exceed standard taking place to wear and tear got final product, and weak point consuming time does not influence production, and wearing and tearing are local replacing when changing, to the appearance and size of adobe almost without any influence.

The specific embodiment

Hot-blast stove shown in Figure 1 checker brick production mould, by die sleeve 1, base plate 2, angle core 3, limit core 4, core bar 5, hole core 6 constitutes.Angle core 3 is the hexagonal pyramid platform, and limit core 4 is a tetragonous cone table, and core bar 5 is the pentagonal pyramid platform, and angle core 3, limit core 4 and core bar 5 are all horizontal by 91 ° tapering setting.Earlier six core bars, 5 usefulness screws 7 closely are fixed on the centre position on each limit of die sleeve during the dress mould, after measurement opposite core stripe pitch is accurate, the limit core 4 of packing in the both sides of core bar, interior angle place at die sleeve wedges angle core 3 between the limit cores 4 with hammer, rely on the tapering of each core that it is combined closely, limit core 4 also closely is fixed on the die sleeve with screw 7, and hole core 6 is contained in the preformed hole that die sleeve presented a theatrical performance as the last item on a programme, and base plate 2 is enclosed within and places the die cavity bottom on the hole core 6.

Claims

1. the mould of hot-blast stove usefulness checker brick comprises die sleeve, Kong Xin and base plate, it is characterized in that: the core bar that on six inwalls of die sleeve, is respectively equipped with the pentagonal pyramid platform, be provided with the limit core in the both sides of core bar, be provided with the angle core at the interior angle place of die sleeve, the angle core closely is connected with the limit core.

2. according to the described checker brick mould of claim 1, it is characterized in that: the limit core is a tetragonous cone table.
