Abstract

The utility model discloses an industrial silicon safe and durable cooling ingot mould which comprises an ingot mould container body, wherein a flat plate graphite block is arranged on the internal bottom surface of a container of the ingot mould container body in an embedding manner. The flat plate graphite block is arranged on the internal bottom surface of the container of the cooling ingot mould container body in an embedding manner, so that graphite is good in high temperature resistance and heat conductivity, and small in thermal expansion coefficient, and the strength of the graphite is improved along with temperature rise; when nearly boiling industrial silicone liquid in a mining heat furnace is poured into the cooling ingot mould container, the graphite block arranged on the internal bottom surface of the container in an embedding manner cannot be corroded when contacted with the oven-fresh high-temperature industrial silicone liquid, and heat can be rapidly conducted and dispersed to the whole cooling ingot mould container by the graphite block; and the cooling ingot mould is durable and safe.

Description

A kind of industrial silicon safety durable cooling ingot mold
Technical field
The utility model belongs to the industrial silicon production technical field, relates to a kind of industrial silicon safety durable cooling ingot mold.
Background technology
Industrial silicon, also referred to as " silicon metal ", " pure silicon ", " Pure Silicon Metal ", after the issue of GB2881-81 " industrial silicon technical qualification " national standard, is formally named as " industrial silicon ".Industrial silicon mainly is divided into metallurgical by silicon and the chemistry large class of silicon two according to purposes.Metallurgical with silicon for the production of fields such as aluminum silicon alloys, chemistry with silicon for the production of aspects such as organosilicon, semiconductor material and solar energy level silicons.
The carbothermic method of modern industry silicon production is the invention of 20 beginnings of the century.The mineral that contain SiO2 of take are raw material, take Carbonaceous matter as reductive agent, and in mineral hot furnace, melting directly makes product, and this method is commonly referred to carbothermic method or electric heating process.For many years, industrially continue to use this method always.Cooling ingot mold is the industrial silicon liquid of fusing to be poured into and is frozen into mould or the container of ingot.The shape of mould or container is determined according to the shape of the required one-tenth ingot of industrial silicon; general shape is the flat rectangular cast iron vessel; because the fusing point of silicon is 1420 ℃; boiling point is 2355 ℃; the fusing point of pure iron is 1538 ℃; the fusing point of common iron is 1500 ℃ of left and right; unavoidable meeting corrode ingot mould body when in mineral hot furnace, the industrial silicon liquid of nearly boiling shape is poured into the cooling ingot mold container; destroy the metallographic structure of ingot mould body; the ferro element that corrode goes out also can reduce the quality of industrial silicon, so people have expected adopting water-cooled durable industrial silicon cooling ingot mold.
For example: in the Chinese patent that notification number is CN201921997U, a kind of polysilicon is disclosed, iron alloy water-cooling heat-resistant cooling ingot mold, comprise groove shape ingot mould body, the bottom of groove shape ingot mould body is provided with water cooled pipeline, because the bottom at groove shape ingot mould body arranges water cooled pipeline, a large amount of heat that polysilicon or metal cooling solidification discharge by the ingot mould bulk absorption after, not only pass through thermal radiation, be transmitted in air, and by the water of the large specific heat in water cooled pipeline, heat is taken away rapidly, rate of heat exchange is fast, so the temperature of ingot mould reduces soon, the position contacted with liquid metal just can guarantee the independence of its structure, be not easy to occur adhesion, sliding injury, fall the phenomenons such as piece, guaranteed the work-ing life of cooling ingot mold, also improved the quality of solidifying rear product simultaneously, the smooth finish of cast(ing) surface is unaffected.
Adopt the industrial silicon cooling ingot mold of such technology certainly can normally use, but have crack as the cooling ingot mold body.High temperature solution will directly touch the water-cooled tube wall, and intraluminal fluid state water will sharply gasify and very easily make the water cooling tube blast, have very large potential safety hazard.
The utility model content
For overcoming the deficiencies in the prior art, the utility model provides a kind of industrial silicon cooling ingot mold of safety durable.
The utility model is to reach the technical scheme that above-mentioned technical purpose adopts to be: a kind of industrial silicon safety durable cooling ingot mold comprises the ingot mould container body; The container interior bottom surface of ingot mould container body is embedded with plate shaped graphite block.
Described plate shaped graphite block is the square graphite piece, and the square graphite piece is embedded the middle part in container interior bottom surface.
The length of described square graphite piece is that 800 millimeters, width are that 800 millimeters, thickness are 120 millimeters.
The beneficial effects of the utility model are: because the container interior bottom surface of cooling ingot mold container body is embedded with plate shaped graphite block.The fusing point of graphite is 3850 ± 50 ℃, high temperature resistant and thermal conductivity good, and thermal expansivity is little, and the intensity temperature improves and strengthens.When in mineral hot furnace, the industrial silicon liquid of nearly boiling shape is poured into the cooling ingot mold container, can be by corrode when the graphite block plate that container interior bottom surface is embedded contacts with oven-fresh hot industry silicon liquid, and heat can be distributed to whole cooling ingot mold container by graphite block plate Rapid Thermal conduction, the durable and safety of cooling ingot mold.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.Wherein:
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is fractionation schematic diagram of the present utility model.
Marker number in accompanying drawing is described as follows: container body 1, graphite block 2
Embodiment
Embodiment of the present utility model, as shown in Figure 1 and Figure 2, a kind of industrial silicon safety durable cooling ingot mold, comprise ingot mould container body 1; The container interior bottom surface of ingot mould container body 1 is embedded with plate shaped graphite block 2.
Described plate shaped graphite block 2 is square graphite pieces 2, and square graphite piece 2 is embedded the middle part in container interior bottom surface.
The length of described square graphite piece 2 is that 800 millimeters, width are that 800 millimeters, thickness are 120 millimeters.
