Abstract
A refractory casting material having self-enforcing action by internal structure regulation when used in high-temp environment is prepared from disthene family of ore, including the micron-class powder of disthene, andalusite and sillimanite, high-aluminium aluminia clinker and binder through proportional mix, and can be used as refractor of high-temp kiln or furnace or to make prefabricated part or non-burning brick. The product has high-temp strength.
Description
The present invention relates to a kind of refractory castable and production method thereof with high temperature self-strengthening.
The high alumina refractory casting material is the refractory materials that extensively adopts in the high temperature kiln.At present the production method of high alumina refractory casting material mainly is to adopt bauxite chamotte and clay and suitable wedding agent mix to form.Because the needed sintering temperature of bauxite chamotte higher (being generally 1550～1600 ℃), and when under being lower than this temperature, using, the refractory castable of Sheng Chaning is lower because of the matrix phase bonding strength in this way, and erosive wear resistance is relatively poor, has influenced the work-ing life of mould material.
The purpose of this invention is to provide a kind of refractory castable and production method thereof that in the high temperature use, has self-strengthening by the adjustment of internal organizational structure.This kind mould material and production method thereof are to add the micron-sized powder (hereinafter to be referred as micro mist) of kyanite family's mineral (comprising kyanite, andaluzite and three kinds of mineral of sillimanite) in common high alumina refractory casting material, and utilize kyanite family mineral micro powder to be decomposed to form mullite and SiO under hot conditions

2The mullite of (melt) this growth in situ can improve the intensity of mould material matrix phase effectively by the fiber reinforcement effect, melt is on good terms and is promoted mould material to realize sintering under lower temperature conditions, thereby the principle that makes this kind mould material in use have self-strengthening realizes.This method technical process is simple, and it is low to obtain the needed temperature of sintering strength, and the mould material hot strength is big, and applied range is easy to implement to promote, and its finished product can be the refractory castablies of diffusing shape, also can be fireproof prefabricated or green brick.
The present invention realizes by following manner.
This refractory castable and production method thereof with high temperature self-strengthening, be that kyanite family mineral (are only used a kind of getting final product wherein, ore down together) obtains the fine ore of kyanite family mineral content＞95% after fragmentation, ore dressing, again fine ore is obtained the kyanite family mineral micro powder of granularity＜20～30 μ m through superfine grinding, and adopts following step to carry out:
(1) batching step: bauxite chamotte and described kyanite family's mineral micro powder and bonding clay, binding agent are cooperated by following parts by weight:
Bauxite chamotte 0～5mm 45～55%
0～0.1mm 30～45％
Kyanite family mineral micro powder＜20～30 μ m 10～25%
Bonding clay＜0.08mm 5～15%
Liquid-containing binder (adding) 8～12%
(2) batch mixing step: raw material is mixed and stirred 5～10 minutes by described proportioning, make it become uniform pug, be described refractory castable with high temperature self-strengthening.
This refractory castable with high temperature self-strengthening, also can on the basis of step (1) and step (2), further make fireproof prefabricated or green brick by following step:
(3) forming step: described refractory castable is made prefabricated component or adobe with brick pressing machine or vibrating forming machine or manual ramming method.
(4) drying step: described prefabricated component or adobe are dried more than 24 hours at 100～110 ℃, or natural air drying is more than 2 days.
Among the present invention, all adopt general-purpose equipment to carry out from the making of mould material and prefabricated component and green brick that be prepared into of raw material.
In the raw material used in the present invention, bauxite chamotte and bonding clay are the general refractory raw material of refractory industry.Kyanite family mineral micro powder is that the ore from kyanite family mineral makes.The ore of kyanite family mineral adopts beneficiation methods such as ordinary method such as flotation, gravity treatment, magnetic separation through fragmentation, obtains the fine ore of kyanite family mineral content＞95%, requires TFe
2O
3＜1～1.5%.Fine ore is pulverized the kyanite family mineral micro powder that obtains granularity＜20～30 μ m with conventional superfine grinding equipment again.
Liquid-containing binder used in the present invention is the general binding agent of refractory industry, as PHOSPHORIC ACID TECH.GRADE solution, spent pulping liquor, water glass solution etc.
Refractory castable of the present invention does not have solid shape, and fireproof prefabricated can be different shape with green brick.
Describe in detail with embodiment below
Embodiment 1
The fine ore that the kyanite ore is obtained containing kyanite＞95% after broken, ore dressing (requires TFe
2O
3＜1～1.5%),, obtains the kyanite micro mist of granularity＜20～30 μ m again with the superfine grinding of kyanite fine ore.Prepare burden according to the following number of weight ratio then:
Bauxite chamotte 0～5mm 45%
