Abstract
The present invention relates to an amorphous refractory material bonded by ambient-temperature solidifying resin, which is mainly used for positions of blast furnaces, rotating furnaces, electric furnaces, steel ladles, iron tap channels, tapping spouts, etc. The amorphous refractory material is prepared from chamotte as a basic raw material, one of non-base refractory raw materials comprising a high alumina wrought material, corundum, silicon carbide, chromia, a carbon material, etc. or a mixture of the non-base refractory raw materials, A-stage phenol formaldehyde resin as a binder, and basic oxides, such as MgO, CaO, etc., as a solidifying agent. The present invention has the technical characteristics of easy production, simple operation, no toxicological harmless substance, good product fluidity, convenient construction, adjustable ambient temperature solidification time, no material precipitation and high intensity. If the amorphous refractory material is used as a pressing material between blast furnace jackets and cooling walls, the corrosion of moisture to the carbon material and the silicon carbide material in the state of high heat can be avoided.
Description
What the present invention relates to is a kind of production method that is used for the cold setting resin of various metallurgical liner region of interest in conjunction with unshape refractory.
So far, domestic and international existing resin-bonded unshape refractory, usually make wedding agent with resole, solidifying agent is one or more the mixture in the mineral acids such as organic acids such as Phenylsulfonic acid or sulfuric acid, and the clear 58-23352 of Japanese Patent has introduced this situation.Owing to adopt acid to make solidifying agent, the bonding strength of formed body is reduced greatly, construct wayward and corrodibility is bigger, be not subjected to on-the-spot welcome.
The objective of the invention is to develop the production method of a kind of ambient cure and non-corrosive resin-bonded unshape refractory.
Cold setting resin of the present invention in conjunction with the production method of unshape refractory is: with the refractory particle material, after fire-resistant fine powder and solidifying agent mix to scale, after adding quantitative resole again and stirring, construct.
Refractory particle material and fire-resistant fine powder can be chamottes, the mixture of one or more in the non-alkaline refractory raw materials such as high alumina, corundum, silicon carbide, chromic oxide, carbonaceous material.Its granularity requirements is: refractory particle material 10-0.088mm, fire-resistant fine powder＜0.098mm.
Solidifying agent can be alkaline refractory oxide, and its requirement is: MgO and CaO resultant 〉=90% (weight), granularity＜0.088mm.
Wedding agent can be a resole, and solid content is 20-80% (weight)
The proportioning of unshape refractory is: refractory particle material 30-70% (weight), and fire-resistant fine powder 70-30% (weight) as radix, adds solidifying agent 0.1-30% (weight), and wedding agent is 6-60% (weight)
Above-mentioned each solid material is even in stirrer for mixing, and the packed working-yard that is transported to joins stirrer with the solid material earlier during construction, adds quantitative wedding agent then, can construct after stirring.The ambient cure time can be controlled according to field requirement.
Unshape refractory of the present invention compared with prior art, following advantage is arranged: solidifying agent is selected basic oxide for use, has simplified production technique; Site operation need not heat, and does not have harmful toxic matter to produce non-corrosiveness; Have suitable time of coagulation and set time, both guaranteed the sufficient engineering time, guaranteed again to solidify in the time not oversize after the construction, effectively avoided the material sedimentation phenomenon; And can shorten the engineering time, improve construction quality; It is little that formed body burns back line variation, the intensity height.
Embodiment: between last furnace shell and the cooling stave with being pressed into the material example
Numbering 1# 2#
Corundum in granules % (weight) 30 30
Corundum fine powder % (weight) 70 70
Light-burned MgO% (adding weight) 23
Resole % (adding weight) 20 20
With above-mentioned corundum in granules and 100 parts of corundum fine powder (weight), add light calcined magnesia (weight), the back that stirs adds resole 20% (weight) mixing and pours in the mould of 25 * 25 * 125mm ambient cure into after 15 minutes, not distortion after the drying, test result sees the following form:
| Numbering | Presetting period (h) | Final setting time (h) | Folding strength (110 ℃ * 24h of MPa |
| 1# | 3 | 8.5 | 18.6 |
| 2# | 2 | 5 | 12.4 |
Claims (3)
1. the production method that refers to the bonded unshape refractory is set in an ambient cure, it is characterized in that: proportioning is: refractory particle 30～70% (weight), fire-resistant fine powder 70～30% (weight), and the alkaline refractory oxide that adds 0.1～30% (weight) MgO+CaO 〉=90% (weight) as radix is made solidifying agent; With above-mentioned mixing of materials evenly after, add after wedding agent resole 6～60% (weight) stirs, construct; Wherein said refractory particle and fire-resistant fine powder are one or more the mixture in chamotte, high alumina, corundum, silicon carbide, chromic oxide, the non-alkaline refractory raw material of carbonaceous material class; The granularity of refractory particle is the 10-0.088 millimeter, the granularity of fire-resistant fine powder＜0.088 millimeter.
2. production method according to claim 1 is characterized in that: solidifying agent is a light calcined magnesia, granularity＜0.088 millimeter.
