The present invention relates to light mullite pouring materials which are prepared from light mullite as porous aggregate, SiO2 miropowder, kyanite, high-Al fine powder, sodium acetate tripolyphosphate, clay, high-Al cement, etc., wherein the light mullite as porous aggregate is prepared from secondary bauxite raw materials, furaldehyde, clay, saw dust, floater, waste slag, coal powder, etc. The present invention has the advantages of low specific weight and heat conduction coefficient, high thermal insulating property, high anti-compression strength, low creep deformation, simple processing procedure and low cost, and simultaneously, the service life of a tundish cover can be prolonged.
Description
The invention belongs to mullite is raw-material metallurgical technical field of refractory materials, is specifically related to a kind of light mullite pouring material.
At present, with mullite is raw-material refractory castable, generally have the bigger defective of volume density, this has just brought mould material self than great when industrial application, and the sealed porosity of mould material own is few, the thermal conductivity height, the unfavorable factor of heat-insulating property difference simultaneously, adopts bauxite chamottes at present in the mullite manufacture craft, processing step is comparatively loaded down with trivial details, and cost is higher.As Chinese patent application number: 9310158.1 disclosed cement-free mullite composite pouring materials.
The objective of the invention is at the deficiencies in the prior art, provide a kind of proportion little, good heat insulating, manufacture craft is simple, lower-cost light mullite pouring material.
The present invention is (consumption is a weight part) of being made by the component of following proportioning
Light-weight mullite porous aggregate particle diameter 10-5mm 10-18 part
5-3mm 13-20 part
3-1mm 10-18 part
1≤mm 15-20 part
400 order SIO
2Powder 4-6 part
Kyanite 4-8 part
Alumina content greater than 70% particle less than 180 purpose high alumina fine powder 13-15 parts
Tripoly phosphate sodium STPP 0.2-0.8 part
Clay 5-10 part
High-alumina cement 5-8 part
Wherein the light-weight mullite porous aggregate is made by following proportioning component, and consumption is a weight part:

Float pearl waste residue 5-10 part
Coal dust 10-15 part
The invention has the advantages that:
1, proportion little, lead that ripe coefficient is low, heat-insulating property is high, the high and low creep of ultimate compression strength.
2, processing step is simple, cost is low.
3, prolong the work-ing life of middle clad, according to Baogang's evidence, can be by an original week
Be increased to three months.
4, in the prescription of mould material, 400 order SIO
2The adding of powder has strengthened the bonding properties of mould material,
The adding of kyanite makes mould material in use, thereby causes that microdilatancy offset high temperature
Shrinkage phenomenon makes overall volume in use reach stable, the intervention of tripoly phosphate sodium STPP
Improved the flowability in the construction cast, alumina content greater than 70% particle less than 180 orders
Thereby the high alumina fine powder effectively be filled in the particles of aggregates gap and improved ultimate compression strength, clay
Thereby adding stopped the dispersiveness in the casting process improved integrated poured associativity and
Time of coagulation, in use played nodulizing.
