Comparative example 1
The embodiment provides a technical scheme: a furnace lining formula with large-particle quartz sand dry vibration materials comprises: adhesive: large-particle quartz sand: the granularity is 6mm-10mm, and the small-particle quartz sand: the granularity is 200 meshes to 6mm.
Preferably, the binder is: 0.5-2 parts; the large-particle quartz sand is: 15 parts.
Preferably, the binder is: boric acid and boric anhydride, the total amount of boric acid and boric anhydride being 0.8 parts.
The particle size of the existing small-particle quartz sand is 200 meshes of quartz sand: 24 parts of a binder; quartz sand with a particle size of 0-1 mm: 38 parts of a mixture; quartz sand with the granularity of 1mm-3 mm: 19 parts of a mixture; the granularity is 3mm-6mm quartz sand: 19 parts of (A).
Through adding the large-particle quartz sand on the existing small-particle quartz sand and carrying out bulk density tests, the large particles on the upper part of the measuring cylinder are found to be stacked, the fine powder is less, and the compactness is insufficient. Probably because the particle size deviation of the quartz sand is 0-1mm, the quartz sand with the particle size of 0.5-1mm is added later, and the particle size deviation is reduced by 6-10mm. The upper layer of large particles is reduced to some extent, but the tested density is 2.18 (standard is more than or equal to 2.2), and the part with particle size distribution larger than 6mm is less, which is not consistent with the direction of large particle products
Comparative example 2
The embodiment provides a technical scheme: a furnace lining formula with large-particle quartz sand dry vibration materials comprises the following components: adhesive: large-particle quartz sand: the granularity is 8mm-12mm.
Preferably, the binder is: 0.5-2 parts; the large-particle quartz sand is: 15 parts of the raw materials.
Preferably, the particle size is 200-mesh quartz sand: 24 parts of (1); quartz sand with a particle size of 0-1 mm: 38 parts of a mixture; quartz sand with the granularity of 1mm-3 mm: 19 parts of a mixture; the granularity is 3mm-6mm quartz sand: 19 parts of (A).
Preferably, the binder is: boric acid and boric anhydride, the total amount of boric acid and boric anhydride being 0.8 part.
The granularity of the existing small-particle quartz sand is 200 meshes of quartz sand: 24 parts of (1); quartz sand with a particle size of 0-1 mm: 38 parts of a mixture; 1mm-3mm quartz sand: 19 parts of a mixture; quartz sand with the granularity of 3mm-6 mm: 19 parts of (A).
Through increase above-mentioned large granule quartz sand on current small granule quartz sand, carry out bulk density test, bulk density value is about 2.23, but the multiunit test shows that the part of >6mm is more, and the large granule exposes and piles up at the graduated flask top, these are because the influence that the particle size distribution of large granule raw materials itself brought, can not avoid completely.
Example of effects:
by comparing the example 1 with the examples 2-8, the comparative example 1 and the comparative example 2, the stacking sealing of the example 1 reaches 2.21, the standard requirement is met, more than 6mm meets the standard requirement, large grain size segregation is not produced in the vibrating process, and the effect is best.
Stacking rate experimental example:
the bulk particle quartz sand dry vibration material is piled up the speed contrast with ordinary granule quartz sand product, can react the speed of building the stove in the actual work progress to vibration time is not enough in the work progress, leads to the tap degree not enough, perhaps vibration time overlength, and the granularity produces the segregation.
Referring to fig. 1, the experimental results show that: the large-particle dry vibration material of the quartz sand can reach the maximum tap density only in one third of the time of a common dry vibration material product of the quartz sand.
Thermal expansion experimental example:
the thermal expansion test characterizes the volume change of the material during the temperature rise and the sintering.
Referring to fig. 2, two sets of thermal expansion parallel tests are performed on a product with 15 parts by mass of large-particle quartz sand, and the results show that the expansion amount is about 5%, the expansion amount is relatively small, and the tested product has few cracks and no shrinkage. The test of multiple groups of bulk densities shows that the bulk density is about 2.20-2.21, the integral embedding degree is better, and meanwhile, when the furnace lining formula of the above embodiments 1-8 is used for actual smelting, the furnace bottom is eroded by 10 centimeters after 70 times of smelting; after the large-particle quartz sand product is used, smelting is carried out for 110 heats, and the furnace bottom is eroded by 3 centimeters. The overall strength and the erosion resistance are superior to those of common quartz sand.
