Technical field

The present invention relates to glass sintering technology field, specially a kind of glass sintering technique.

Background technique

Glass is amorphous inorganic non-metallic material, and usually with a variety of inorganic minerals, (such as quartz sand, borax, boric acid, weight are brilliant Stone, barium carbonate, lime stone, feldspar, soda ash etc.) it is primary raw material, it additionally incorporates made of a small amount of auxiliary material.It it is main at It is divided into silica and other oxides.

The chemical composition of simple glass is Na2SiO3, CaSiO3, SiO2 or Na2OCaO6SiO2 etc., main component It is silicate double salt, is a kind of non-crystalline solids of random structure.It is widely used in building, is used to belong to every wind light transmission Mixture.Separately have the oxide for being mixed into certain metals or salt and show the coloured glass of color, and by physics or Tempered glass made from the method for person's chemistry etc..Sometimes some transparent plastics (such as polymethyl methacrylate) are also referred to as had Machine glass.

The forming of glass is that the glass metal of melting is changed into the process with geometry product, this process is referred to as The once-forming or hot end of glass shapes.Glass must could shape in certain viscosity (temperature) range.In forming, glass Glass liquid also carries out continuous heat exchange and heat transmitting with surrounding medium in addition to doing mechanical movement.Glass metal is first by stickiness liquid State is changed into mecystasis, is then transformed into brittleness solid-state again, and therefore, the forming process of glass is extremely complex process.

Chemical composition stability, epigranular, high-quality burning Well-recovered, metallurgical performance is high can be provided for blast furnace by sintering Mine is tied, for blast furnace is high-quality, high yield, low consumption, longevity create good condition；Objectionable impurities such as sulphur, zinc etc. can be removed, it can benefit With industrial waste, such as blast furnace dust, mill scale, sulfate slag, steel slag；Recyclable non-ferrous metal and rare rare earth gold Belong to.

Our company's product is mainly table top TVS product, and P/N knot protection uses glass passivation process, currently, in glass Hole is easy to appear in sintering process, and some gases cannot be well soluble in glass powder.

Summary of the invention

It is good that the purpose of the present invention is to provide a kind of anti-interferences, the high glass sintering technique of stability, above-mentioned to solve The problem of being proposed in background technique.

To achieve the above object, the invention provides the following technical scheme: a kind of glass sintering technique, comprising the following steps:

A, prepare the raw material of glass sintering and the smelting furnace of sintering；

B, raw material is sent into sintering furnace sintering to melt, while is passed through protective gas；

C, a stationary temperature is kept for a period of time after glass raw material thawing, glass raw material is made to be in liquid；

D, glass cooling is made to condense into solid glass shape.

Preferably, described that silica sand or 20 parts -25 parts of borax are prepared according to step A, 10 parts -15 parts of saltcake, dolomite 30 - 40 parts of part, 15 parts -30 parts of cullet, a closed smelting furnace.

Preferably, described that silica sand or 25 parts of borax are prepared according to step A, 15 parts of saltcake, 35 parts of dolomite, 25 parts broken Glass.

Preferably, described that glass raw material is put into smelting furnace according to step B, and smelting furnace is vacuumized, make glass raw material 1300 DEG C -1600 DEG C at a temperature of melted, while carrying out glass raw material thawing injection and mixed gas, N₂: O₂ For 1:12.

Preferably, make temperature of the glass raw material of liquid at 1300 DEG C -1600 DEG C after the thawing according to step C glass raw material Degree is lower to keep 10min-15min, at the same be constantly passed through to smelting furnace and mixed gas.

Preferably, described that the glass solution of liquid is injected into shaping grinding apparatus according to step D, make the temperature control of grinding tool slot It makes in 900 DEG C -1000 DEG C of range, using making glass natural cooling after molding after mechanical compression molding.

Compared with prior art, the beneficial effects of the present invention are:

The present invention is carrying out injecting N when glass raw material is sintered₂Add O₂Mixed gas, gas can be good at It is dissolved in glass powder, can be avoided glass and occur cavity during sintering, and contain N₂Mixed gas it is anti-interference Property it is good, stability is high.

Detailed description of the invention

Fig. 1 is N of the present invention₂And O₂Flow and cavity are in dependency diagram.

Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

Fig. 1 is please referred to, the present invention provides a kind of technical solution: a kind of glass sintering technique, it is characterised in that: including following Step:

A, prepare the raw material of glass sintering and the smelting furnace of sintering；

B, raw material is sent into sintering furnace sintering to melt, while is passed through protective gas；

C, a stationary temperature is kept for a period of time after glass raw material thawing, glass raw material is made to be in liquid；

D, glass cooling is made to condense into solid glass shape.

Prepare silica sand or 20 parts -25 parts of borax, 10 parts -15 parts of saltcake, 30 parts -40 parts of dolomite, 15 parts -30 parts broken Glass, a closed smelting furnace.

Glass raw material is put into smelting furnace, and smelting furnace is vacuumized, makes temperature of the glass raw material at 1300 DEG C -1600 DEG C Under melted, while carrying out glass raw material thawing injection and mixed gas, N₂: O₂For 1:12, with oxygen content Increase, the quantity in the cavity for the inside glass for being sintered out gradually decreases.

When carrying out glass raw material thawing, by adjusting N₂: O₂The ratio of mixed gas is found, works as N₂: O₂Ratio When for 1:12, glass can be effectively avoided to occur cavity during sintering, and from containing N₂Mixed gas it is anti- Interference is good, and stability is high, therefore using the N of 1:12₂: O₂Mixed gas.

Glass raw material melt after make the glass raw material of liquid 1300 DEG C -1600 DEG C at a temperature of keep 10min-15min, It is melted glass raw material gradually at high temperature, 10min-15min is to guarantee that glass raw material is all complete at high temperature Melt, and is merged again uniformly after melting, while being constantly passed through N to smelting furnace₂With O₂Mixed gas, O₂It can be molten well In glass powder, glass raw material is made fully to be burnt, N is added₂The electric leakage feelings of later product can be reduced when sintering Condition.

The glass solution of liquid is injected into shaping grinding apparatus, the temperature of grinding tool slot is made to control the model at 900 DEG C -1000 DEG C It encloses, using making glass natural cooling after molding after mechanical compression molding.
