Granulated blast-furnace slag
Granular slag or granular slag is a fine fraction (<10 mm) bulk multicomponent material, preferably glassy, obtained by rapid cooling of liquid hot slag water formed, for example, during the smelting of pig iron in a blast furnace or converter.
Has good binder properties. It is used, for example, in the manufacture of cement as an active mineral additive. In addition, a granulated slag is made of ground granulated slag, which is used for concrete production.
LLC “S-TRADE LOGISTIC” offers sale and supply of blast furnace slag granulated by wagon parties (gondola cars or hoppers). The product meets the requirements of DSTU B B.2.7-302: 2014, DBN B.1.4.-001-97, is radiation-safe and can be used for processing.
Blast furnace slag
It is a by-product or waste from the production of metal, after cleaning up the residues of valuable components (impoverishment) is sent to the dump.
Slag is used for the manufacture of building materials (brick, tile), as an additive to cement (there are also cements made entirely of slag), as a fertilizer.
LLC “S-TRADE LOGISTIC” offers sale and supply of blast furnace slag fraction 0-250 mm by carriage parties (gondola cars or hoppers). The density of the material in the cooled state is 2700-3000 kg/m3, the bulk density is 1300-1500 kg/m3.
Ground granulated blast-furnace slag
Powder-crushed blast furnace slag of alumina-silicate melt, which is formed during the smelting of pig iron.
It is used to fill waste voids in the course of mine work, is used in cement production, is used for the manufacture of mortars and concretes in hydraulic, agricultural, road construction, construction of industrial, public and residential buildings, structures. Used for the manufacture of artificial conglomerate and dry mixes.
The product meets the requirements of TU U 27.1-00204607-019: 2008.
Ground granulated slag
Ground granulated slag – a product obtained by fine grinding of granular blast furnace slag with or without a hydrophobic additive
The additive intensifies grinding and ensures its preservation during storage and flow during transportation.
Grinding fineness 0-0,080 mm. Sieve residue 008 to 20%. Humidity 0.05%.
We offer ground slag with delivery by wagon parties (hoppers) or automobile cement trucks.
Kaolin
White clay composed of kaolinite mineral. It is formed during the destruction (weathering) of granites, gneisses and other rocks containing feldspars (primary kaolins).
As a result, the primary kaolins are washed away and their sedimentation occurs in the form of sedimentary rocks; secondary kaolins are formed, also called kaolin clays.
The main properties of kaolin are high fire resistance, low ductility and bonding ability.
LLC “S-TRADE LOGISTIC” sells kaolins of brands KO-0, KO-1, KO-2, KO-3 that meet the requirements of TU 322-7-00190503-127-97.
Secondary kaolins are used for:
– production of high quality refractory products;
– production of construction ceramics, porcelain and earthenware;
– cement production;
– production of molding material in foundry production;
– production of rubber products;
– production of propant.
Coal trifle
Coal trifle is produced by sintering at high temperatures (more than 1000 degrees) without oxygen access to high quality coking coal, resulting in a large amount of harmful toxic volatile impurities.
The result of coking is high-calorie сoal . Сoal trifle breeze is made in the process of scattering the total mass of the coke obtained into different fractions. Сoal trifle has a fraction of 0-10 mm. The product has a porous structure and develops a combustion temperature of up to 1500 degrees (under special conditions). Сoal trifle breeze is used to increase the electrical conductivity of soil and electrolyte area;
in the production of electrode products (coal, cathode carbon graphite and floor blocks, electrode mass, graphite electrodes, etc .;
in the production of electrocorundum for the abrasive industry;
for the production of refractories. Сoal trifle breeze is widely used in the metallurgical and many other industries.
Our company sells car parts of coke trifle KM-1 of fraction 0-10mm with the following quality indicators:
– Ash – no more than 15%.
– Volatile Matter – no more than 3%.
– Sulfur – not more than 0.5%.
– Total Moisture – not more than 15%.
Coal nut
This is the elimination of coal of the fraction of 10 – 25 mm, obtained during sorting of coal.
Used as a fuel and carbon reducing agent.
Coke nut is used in non-ferrous metallurgy, in ferroalloy and electrode production.
Our company sells car parts of coke coal KO of fraction of 10-25 mm with the following quality indicators:
– Ash – no more than 14%.
– Volatile Matter – not more than 1.5%.
– Sulfur – not more than 0.5%.
– Total Moisture – not more than 10%.
Coal metallurgical
Metallurgical coal is a solid coal, baked at high temperatures in special ovens, the baking temperature is 950-1200 ° C.
The main application is the smelting of iron to produce iron.
Our company sells car parts of coke metallurgical fraction of 25-40 mm; more than 40 mm; more than 60 mm with the following quality indicators:
– Total Moisture – up to 5% (according to the certificate – 4.9%).
– Ash – up to 14% (according to the certificate – 13,3%).
– Volatile Matter – up to 0.6% (with certificate – 0.4%).
– Sulfur – up to 0,5% (according to the certificate – 0,39%).
– Carbon (Fixed Carbon) – not regulated (estimated – 80-85%).
– Crushing Strength – M40-87%.
– M25 is not regulated.
– M10 – 8.2%.
