Background

The heating furnace kiln usually needs to keep very high working temperature for a long time due to the requirement of heating working condition, and the high temperature difference between the inside and the outside of the furnace wall causes the heat preservation of the furnace kiln to be difficult.

In order to solve the problem of heat loss of the furnace, according to a heat transfer mathematical model of a heating furnace and a physical blackbody theory, a compound design of transition metal oxides, carbides, nitrides, borides, silicides and the like is selected, and the mixture is extruded into a cavity frustum with a certain thickness and an opening at the top end through a die, and is sintered into a high-temperature-resistant high-emissivity engineering blackbody element similar to a theoretical blackbody through the furnace.

Generally, the element substrate is made of radiation materials with main radiation wave bands within the range of 2.5-12 mu m, such as Al2O3, siO2, fe2O3, mnO2, niO, cuO, co2O3, cr2O3, zrO2, tiO2, mgO and the like, according to certain component configuration; then, the elements are reasonably arranged and installed on the inner wall of the furnace kiln so as to improve the blackness of the surface of the hearth, increase the radiation area of the hearth and improve the heating speed of the hearth, thereby enhancing the heat exchange and heating efficiency of the hearth and realizing the energy conservation and emission reduction with higher efficiency.

However, in practical applications, as shown in fig. 2 and 3, most of the energy-saving elements for heating furnaces and kilns are installed on the top of the furnace chamber, and the bonding surface is usually directly painted with a high-temperature adhesive and a single-fastening screw cold-state auxiliary fixing mode is adopted to penetrate through the center of the bottom of the energy-saving element, so as to ensure the firmness of the bonding surface between the energy-saving element and the furnace top, but the above structure has the following disadvantages:

1. the bottom of the energy-saving element and the inner wall of the hearth are easy to generate dislocation, pore and layering due to the low initial adhesion of the bonding surface during natural solidification at normal temperature, vibration and self gravity during construction and the like, so that the bonding strength of the bonding surface is low, the elements fall off more, and the energy-saving reconstruction effect is seriously influenced;

2. after the single-fastening ceramic screw penetrates through the limiting installation of the center of the bottom of the element, the adhesion plane cannot be well limited by a single point, so that the adhesion degree of the bottom of the element and the adhesion surface of the furnace wall is not high enough, the double functions of pressurization and fixation are difficult to play, the element falls off even without increasing the process temperature, and the continuous energy-saving improvement effect is difficult to embody.

Therefore, how to solve the defect that the dropping rate of the energy-saving element installed by the single-point limiting method adopted by the existing energy-saving element is still higher, the dropping rate of the element is further reduced, the service life of the energy-saving element is ensured, and the heating furnace kiln can continuously save energy for a long time, which becomes a technical problem to be solved by technical personnel in the field.
