Abstract: the results of the designing composition of the refractory ramming masses of dinas happen to in article on base row to compositions, containing quartzite, kaolinite of the clay, quartz sand, limestone, bentonite, waste metallurgical production. Will Installed positive influence mineral additives on regeneration of the quartzite under firing compositions.

Аннотация: в статье приводятся результаты проектирования составов динасовых огнеупорных набивных масс на основе ряда композиций, содержащих кварцит, каолинитовую глину, кварцевый песок, известняк, бентонит, отходы металлургического производства. Установлено положительное влияние минерализующей добавки на перерождение кварцита при обжиге композиции.

Keywords: refractory, dinas, ramming mass, quartzite, kaolinite of clay, metallurgical waste, tridimite, crystobalite.

The Known [1, 2], refractory industry plays the essential role in is blazed-metallurgical complex, which occupies the strategic important place in economy all over the world. Exactly this branch sharply needs for introduction in production modern scientifically-technological decisions, providing increasing to competitiveness to refractory product on of the world market, as well as in Republics of Uzbekistan at reduction of the use to energy, cheese and material.

Herewith follows to note that deficit domestic high-quality no ore mineral-raw materials resource for production refractory material conditions need of the complex study earlier reconnoiters deposits, as well as involvement in production their notraditional of the deposits. So, problem of the expansion of the raw materials base to refractory industry of of Uzbekistan to account of involvement notraditional natural and secondary raw materials resource, today remains the urgent problem in connection with exigence of the ensuring the row production enterprise Republics different additional type raw materials.

For development optimum composition of the refractory ramming masses of dinas prepared the following row a composition on base mineral raw materials resource: «quartzite-clay», «quartzite-clay-sand-limestone», «quartzite-clay-sand», «quartzite-clay-limestone-bentonite», «quartzite-clay-limestone- metallurgical waste» with corresponding to correlations source raw materials component (table 1).

Table 1. Compositions charge under investigation ramming masses

№ Name raw materials Number charge

KG KGSL KGS KGLB KGLW

1 Quartzite 75-90 45-70 45-85 72-86 72-86

2 Kaolinite of clay 10-25 5-15 15-25 10-15 10-15

3 Quartz sand - 25-50 25-50 - -

4 Limestone - 1,5-2 - 1.5-2 1.5-2

5 Bentonite - - - 5-10 -

6 Metallurgical waste - - - - 5-10

For reception charge on base source raw materials component, in the beginning source quartzite was subjected to preliminary crushing in to grinder and wash by water for removing different the clay admixtures. Then, the raw materials mixture stoichiometry composition moistened water before reception of the mass to plastic consistency, subjected to pressing in the manner of tablets.

The Sample during at the temperature 150-180°C during 2-2,5 hour. Hereinafter during sample subjected to the high temperature an thermal processing in interval of the temperature 1300-1450°C with endurance under final temperature during 1 hour. Fullness of the process of the reception of the ramming masses with perfected physico-mechanical and technological characteristic checked the degree of the regeneration of silica in mass. The Regeneration of silica or begin crystobalite and tridimite fixed by means of the study such as microscopic and roentgen graphic methods.

Thereby, on the grounds of crystallooptic and product analysis roentgen graphic of the interaction said composition is installed that at the temperature above 1400°C in test KG. KGSL, KGS, KGLB, and KGLW begins formation crystobalite, which also influences on increasing of toughness of the pilot models of the ramming masses. But herewith rifts appear in pilot models. When in mass is added mineral additive, in the manner of ferrous departure metallurgical production occurs formation tridimite, being main mineral refractory material of dinas, conditioning maximum toughness of the ramming masses.

Аннотация: в данной статье рассматриваются свойства грунтов и возникающие в них процессы при действии динамических нагрузок. Динамические нагрузки подразумевают собой вибрации, сейсмику, удары и взрывы, вызывающие различный характер воздействия от длительно повторяющихся и плавно меняющихся во времени нагрузок до одиночных импульсов и ударных волн, при которых нагрузки на грунт возрастают практически мгновенно. Данная тема является актуальной для города Алматы, так как город находится в сейсмической зоне.

Abstract: in this article properties of soil and processes arising in them at action of dynamic loadings are considered. Dynamic loadings mean themselves - vibrations, seismicity, blows and the explosions causing various nature of influence from is long loadings repeating and smoothly changing in time to single impulses and shock waves at which loads of soil increase almost instantly. This subject is actual for the city ofAlmaty as the city is in a seismic zone.
