- Cooling with a temperature higher than the temperature of the liquid alloy of the alloy is greater than 70 ° C, resulting in an irregular or severe temperature loss.
- cooling with a temperature of 40 ⁇ 70 C higher than the temperature of the alloy of the alloy ensures that there is an increase in the cost of the load of the product.
- Alloy on the basis of aluminum of grade 01959 in the amount of 104 kg (at the same time, the solidus-liquid of 620-640 C) is melted and is separated by a temperature of 750–800 ° C. min ⁇

- the particles of the mixture of the alloy with ⁇ , ⁇ 2 after the spray were directed into the water for cooling. After separating the particles from the water and drying, 95 kg of the particles of aluminum alloy with ⁇ 2 , were obtained. This mass of particles was divided into five parts of 18 kg each and one share of 5 kg.
- the first portion of the particles (18 kg) was double-tempered in an oxygen-free atmosphere (in the case of an accelerator) at a constant temperature. ⁇ As a result, we received 18 kg of industrial particles with a density of 600 kg / m 3 . Last year, it was around 100%. The particles were used to fill the cottage, which was used as a vehicle for the use of the vehicle, and it was used for loading the car A short supply of particles (18 kg) was sent to the hot pack for a good supply of ready-to-eat food.
- the particles were encapsulated in a capsule with a diameter of 290 mm, a height of 174 mm from an aluminum alloy ⁇ ⁇ ⁇ , heated to a temperature of 455 ° ⁇ , and a pressure of 40x250x710 mm was applied.

- the sheets were heated to a temperature of 700 ° C (that is, 60 ° C higher than the temperature of a solid-liquid alloy 01959) and settled. As a result, we obtained large sheets of equal thickness, which are in the range of 15.2 mm to 15.9 mm. Last year it was 100% here.
- the group of particles (18 kg) was divided into six equal parts of 3 kg each. First of all, we fell asleep in a regular corner with a height of 5 mm; After cooling, we obtained a clear 12 mm high briquette with quick openings between sintered open spherical particles. They neglected the second layer of particles, 5 mm high, and repeated the above described operations of heating and cooling.
- the first sheet was heated to a temperature of 630-640 with a speed of 100 g / min., and then it was kept at a temperature of 700 ° C for a complete termination of defrosting, and ⁇
- the second sheet was heated in a temperature of up to 700 C for a full frothing and cooled, the speed of heating of a sheet at a temperature of 630-640 ° C was 60 ° C.
- the resulting sheets had the following sizes:
- the sixth portion of the particles (5 kg) was filled in with a large complex compound.
- the unit with the particles was placed in the furnace with a remote atomic (hydrogen) and doubled at a temperature of 700 ° C. ⁇ master ⁇
- the density of the finished product was 0.36 g / cm3.
- the product was exchanged as a catalyst carrier for the selective absorption of gas mixtures. From the above example, it can be seen that, as a result of its use, the yield can be increased annually by 98-100%. and expanded on the range of finished products manufactured from sold metal-containing particles.

Β As a result, we received 18 kg of industrial particles with a density of 600 kg / m 3 . Last year, it was around 100%. The particles were used to fill the cottage, which was used as a vehicle for the use of the vehicle, and it was used for loading the car A short supply of particles (18 kg) was sent to the hot pack for a good supply of ready-to-eat food. For this purpose, the particles were encapsulated in a capsule with a diameter of 290 mm, a height of 174 mm from an aluminum alloy Α ДЗ Ι, heated to a temperature of 455 ° С, and a pressure of 40x250x710 mm was applied.

The sheets then doubled over the thermal treatment at a temperature of 700 ° C in an oxygen-free environment (argon) under atmospheric pressure. Уль As a result, we obtained simple products in the form of sheets-cards with a size of 32x600x1000 mm. There were no defects, cracks or other problems or defects on the surface of the sheets. Last year it was 100%. The sheets are used for a costly business of facades. The fifth partisation (18 kg) was overheated in the same mode, which also included the second and the fourth part.

Пοлученные лисτы имели следующие ρазмеρы:- the second sheet was heated in a temperature of up to 700 C for a full frothing and cooled, the speed of heating of a sheet at a temperature of 630-640 ° C was 60 ° C. The resulting sheets had the following sizes:

And with this, the density of the pass was found to be 20% lower than the second. For this reason, various types of heating have ensured, and other conditions are different, and there is a reduction in the volume of the process, The sixth portion of the particles (5 kg) was filled in with a large complex compound. The unit with the particles was placed in the furnace with a remote atomic (hydrogen) and doubled at a temperature of 700 ° C. Уль As a result, we received a product of a complicated configuration with a regular front-end structure in a quick-start-up environment. The density of the finished product was 0.36 g / cm3. The product was exchanged as a catalyst carrier for the selective absorption of gas mixtures. From the above example, it can be seen that, as a result of its use, the yield can be increased annually by 98-100%. and expanded on the range of finished products manufactured from sold metal-containing particles.
