Abstract:
The group of inventions consists of metal heat treating methods, method for the liquid or gaseous fuel and hot air combustion in a direct or indirect fired furnace, a heating device and regeneration nozzles for carrying out said method. The inventions relate to metallurgy and mechanical engineering and can be used for metal heat processing (melting, heating for deformation, heat treatment) and for sintering, drying and other types of heat treatment of non-metallic products, for example ceramics. The essence of each invention discloses novel technical features which make it possible, while implementing the inventions, to attain the air excess factor (a) values in the fuel and hot air mixture which are greater than 2.0 and mainly set in a range equal to or less than 6.0. Said inventions make it possible to reduce a waste of metal during the processing thereof in a direct or indirect fired furnace and to decrease the metal hydrogenation levels including aluminium, titanium and iron alloys. The use of the invention in the indirect fired furnaces makes it possible to extend the service life of radiant tubes and melting pots. Experimental data items obtained by the inventors prove that the technical result is attained by the respective composition of the atmosphere (gaseous phase) of combustion products of the liquid or gaseous fuel and hot air mixture with the air excess factor (a) values greater than 2.0.

Группа изобретений включает способы тепловой обработки металла и способ сжигания смеси жидкого или газообразного топлива и нагретого воздуха в пламенной печи прямого или косвенного нагрева, а также устройства отопления и регенеративные насадки для осуществления способов. Изобретения относятся к металлургии и машиностроению и могут быть использованы как при тепловой обработке металлов (плавление, нагрев под деформацию, термообработка), так и при обжиге, сушке и другой термической обработке неметаллических изделий, например, керамики. Сущность каждого из изобретений отражают новые технические признаки, обеспечивающие при реализации изобретений достижение значений коэффициента избытка воздуха (α) в смеси топлива и нагретого воздуха, превышающих значение 2,0 и устанавливаемых преимущественно в диапазоне до 6,0. Технический результат при использовании изобретений заключается в снижении угара металла в процессе его обработки в пламенной печи прямого нагрева (фиг.4) и в снижении уровня наводораживания металлов, в том числе сплавов алюминия, титана, железа. При использовании изобретений в печах косвенного нагрева техническим результатом является повышение срока службы радиационных труб и тиглей. Экспериментально полученные авторами изобретений данные свидетельствуют о том, что указанный технический результат достигается за счет обеспечения соответствующего состава атмосферы (газовой фазы) продуктов сгорания смеси горячего воздуха с жидким или газообразным топливом при значениях коэффициента избытка воздуха α, превышающих значение 2,0.

One or more cavities (202) extend from the inner face (210) partially into the brick (200). A plurality of channels (208) for each of the cavities (202) extend from the outer face to the cavities (202) and channels (208) allow a gas to pass through the brick (200). Also provided is a hot grid (114) suitable for use in a regenerative heat exchanger (100) formed from a plurality of the bricks (200).
Abstract:
A metal oxide coating (18) has a nanotextured surface (22) defined by a plurality of capillary openings (20) arranged in a pattern on the surface of the coating (18). Each of the capillary openings (20) have a diameter defined by a previously present organic macromolecule (10). The metal oxide coating (18) is formed by depositing a solution containing uniformly dispersed micelles (10) composed of amphiphilic molecules (12) on a metal, oxide, or plastic substrate (16). The micelles (10) are self-arranging, in solution, as a result of mutually repulsive electrostatic forces on the surface of the micelles (10), and form a uniformly patterned organic template (14) when the solution is deposited on the surface of the substrate (16). A metal oxide coating is then applied to the substrate (16), which forms a ceramic monolayer that is a negative image of the organic template (14). The organic template (14) is then removed, thereby forming a metal oxide coating (18) having a plurality of macromolecular-sized apertures (20) formed therein.

The treatment liquid preferably has a nearly neutral pH and is applied to a substrate and dried in place by exposure to heat.
