Abstract

A mould integrated with a cap for casting large steel ingots belongs to metal casting, and is particularly relates to a steel ingot mould for metal casting. The cap section of the mould and an ingot mould section are integrated into a whole body, a cylindrical cavity is arranged at the cap section, and an obconical cavity is arranged at the ingot mould section. The mould is characterized in that a petal-shaped cap groove is arranged on the inner wall of the cavity of the cap section, and a heating panel is hung by a rod and a hanging iron sheet and is embedded into the cap groove. When casting is carried out, molten steel enters the cavity of the ingot mould section and the hanging heating panel of the cap section, and is burnt and kept warm by the heat-generating agent of the heating panel. The mould has the advantages that:1, the mould has ingenious design and simple and reasonable structure; 2, the mould has safe operation and is reliable; 3, the mould has multiple functions, can greatly reduces the number of the moulds, reduces the mould opening cost, saves investment, and reduces the production cost; and 4, the heating panel has good use effect, the molten steel at the cap section can be kept in a liquid state for a long time so that the contraction of the cap is benefited, the contraction cavity of the steel ingot head can be better treated, and the quality and the yield of the steel ingot are improved.

Description

The casting large steel ingot mould of hat cone one

Technical field

The utility model belongs to metal casting, relates in particular to the metal casting ingot mould.

Background technology

Forging-grade ingot is the large-scale steel ingot more than 20 tons particularly, adopts the steel ingot mold pressing to add the cap mouth more and pours into a mould, and is incubated by the cap mouth, prevents shrinkage cavity, guarantees product quality.China Intellectual Property Office's disclosed " large ingot mould cap mouth " is exactly to adopt the cap mouth of ingot mould and ingot body size coupling to pour into a mould (ZL03232433.2).Its cap mouth is the double-decker of foundry iron+heat-insulating shield liner.Its defective is: cap mouth and ingot mould ingot body size will be mated, and the only corresponding a kind of ingot mould of promptly a kind of cap mouth will be poured into a mould the steel ingot of multiple weight grade, must adopt a plurality of cap mouths and multiple ingot mould coupling, and interchangeability is poor, and the accessory consumption is big; The easy bleed-out of the seam crossing of cap mouth and ingot mould influences ingot quality; The ingot mould cap volume ratio is big, and butt ingot is many, and yield rate is low.China Intellectual Property Office's disclosed " straight mouthful ingot mould of back draught " (ZL91218835.9) changes ingot mould inner chamber suitable for reading into straightway, and the straightway lower end has step; The heat-insulating shield upper end is provided with boss, and the insulation board lower end withstands on the interior step of ingot mould, and it is suitable for reading that the upper end boss clamps ingot mould.Such structure can be stopped because of cap mouth and ingot mould seam crossing badly bleeding, reduces finished product steel ingot processing capacity.But defective is: the heat-insulating shield fixed-site, a kind of ingot mould can only be poured into a mould the steel ingot of a heavyweight, still will prepare enough the ingot mould of the steel ingot of the multiple Different Weight grade of cast for the workshop of producing multiple heavyweight.

Summary of the invention

In order to overcome the defective that prior art exists, the purpose of this utility model provides the mould of a kind of casting large steel ingot with the hat cone one, the hat cone one, and one module multiple usages reduces number of molds, reduces the die sinking expense; Handling safety, reliable, favourable raising ingot quality and yield rate.

The casting large steel ingot mould of hat cone one, comprise cap mouth section and ingot mould section, cap mouth section and ingot mould section are connected as a single entity, establish circular cylindrical cavity in the cap mouth section, establish the turbination cavity in the ingot mould section, be characterized in: the cavity inner wall of described cap mouth section is all established petal cap port recess, and heating board is by peg and hang iron plate and hang and be inlaid in the cap port recess that cap mouth section establishes.

Described heating board is the heat-insulating shield that contains exothermic mixture, by the burning of exothermic mixture in the heating board, discharges enough heats, makes the interior molten steel of ingot mould cap mouth section keep liquid for a long time, helps the cap mouth and shrinks, and guarantees product quality.

Described heating board is elongated, and one side has petal projection, and is corresponding with the cap port recess, is flush-mounted in the cap port recess; Heat-insulating shield top is established and is hung iron plate, hangs iron plate and establishes 15 circular holes along its length at least, and peg passes circular hole and rides on the cap mouth section bead.According to the weight of cast steel ingot, calculate the height of hanging of heat-insulating shield, determine the ordinal number of the circular hole that peg passes.The ordinal number of the circular hole that the change peg passes just can change heat-insulating shield and hang height, in order to control institute pour steel amount, to produce the steel ingot of 15 kinds of weight grades.

During cast, steel ingot enters the ingot mould inner chamber by the ingot mould bottom, is rising up into the heating board place that cap mouth section is established, and the exothermic mixture burning of heating board discharges heat energy, carries out insulated pouring.

Compared with prior art, advantage is: novel, simple and reasonable for structure; Handling safety, reliable, one module multiple usages as long as mobile heating board is hung height, just can pour into the steel ingot of 15 kinds of Different Weight, significantly reduces number of molds, reduces the die sinking expense, reduces investment outlay; The good heating board of use heating effect makes the interior molten steel of ingot head opening section can keep the liquid core for a long time, and is favourable to the contraction of cap mouth, solves to be the ingot head shrinkage cavity, improves the quality and the yield rate of steel ingot.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is the mould structure schematic diagram of casting large steel ingot with the hat cone one.

Fig. 2 is the A-A view of Fig. 1.

Fig. 3 is the heating board front view of Fig. 1.

The specific embodiment

By among Fig. 1, Fig. 2, Fig. 3 as can be seen, the casting large steel ingot is linked into an integrated entity by cap mouth section 2 and ingot mould section 1 with the mould of hat cone one.Establish circle shape cavity 4 in the cap mouth section 2, establish the turbination cavity in the ingot mould section 1, both link up and communicate, and ingot mould section 1 is divided into steel outlet hole.On cap mouth section 2 inner chamber body 4 walls, cap port recess 5 is set evenly, cap port recess 5 cross sections are petal.Heating board 6 is a strip, and one side has projection 7, and its cross section is petal, and corresponding with cap port recess 5, and during setting-in heating board 6, the projection 7 of heating board 6 embeds in the cap port recess 5, heating board 6 is securely fixed on the internal chamber wall of cap mouth section 2.Heating board 6 tops are established and are hung iron plate 8, hang and establish 15 circular holes 10 on the iron plate 8.Lifting is during heating board 6, and peg 9 passes the circular hole of hanging on the iron plate 8 10 earlier, hangs up properly heating board 6, then tringle 9 is ridden on the bead of cap mouth section 2, with fixing heating board 6 hanging highly in cap mouth section.Change the ordinal number of the circular hole 10 that peg 9 passes, promptly can mobile heating board 6 hang height, just change the weight of pour steel, the steel ingot of cast Different Weight.Originally pour into a mould the steel ingot of 20-135 tonne Different Weight, need 42 molds, only use 8 molds now, just can realize.
