Abstract
The refractory material is used in related positions for blast furnace, converter, electric furnace, steel ladle, iron tap channel, trough etc., its raw material can be one or several kinds of non-base refractory materials, such as clay wrought material, high alumina wrought material, corundum, silicon carbide, chromic oxide and carbon, the bonding agent is phenolic resin, the curing agent is basic oxide, such as MgO, CaO etc., it features easy production, simple operation, nontoxic, adjustable curing time and high strength.
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＜0.088mm.
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 a 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, add solidifying agent 0.1-30%(weight), wedding agent is a 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) mix after 15 minutes and pour in the mould of 25 * 25 * 125mm, ambient cure, not distortion after the drying,
Test result sees the following form:
| Numbering | Presetting period (h) | Final setting time (h) | 110 ℃ * 24h of folding strength (MPa) |
| 1# | 3 | 8.5 | 18.6 |
| 1# | 2 | 5 | 12.4 |
