Abstract
The invention discloses a production process of a high radiation refractory brick for a heating furnace. The production process comprises two methods such as a brick blank spray coating method and a finished brick spray coating method, wherein the brick blank spray coating method comprises the following specific process: producing a refractory brick blank according to a conventional process, spraying a high radiation coating material on a brick side surface facing the inner chamber of a heating furnace, and conveying the refractory brick into the heating furnace to carry out sintering after completing air drying of the refractory brick in air, and the finished brick spray coating method comprises the following specific process: producing a refractory brick according to a refractory brick production process, building the refractory brick in the heating furnace, spraying a high radiation coating material on a brick side surface facing the heating inner chamber, and carrying out heating and kiln warming-up along with the kiln. According to the present invention, the high radiation coating material layer is sprayed on the refractory brick, and heat is transferred to a heated object through radiation during the heating furnace heating process with the high radiation coating material layer so as to improve radiation heat transfer efficiency and save energy sources.
Description
Technical field
The present invention relates to a kind of refractory brick manufacture craft.
Background technology
In recent years, the rising principal element of glass manufacturing cost is rising violently of fuel cost, energy consumption cost 〉=total manufacturing cost 40-55% or higher, therefore, save energy has become the problem of the most important thing of research, and various energy-conservation technological inventions or innovation come into one's own.
Adopt the glass kiln of gas, liquid and solid (refinery coke) fuel, fusing section fuel directly sprayed from metal level, and clarification afterwards, cooling end do not have fuel and conduct heat.To discovering of thermal conduction study: convection current, conduction, three kinds of heat transfer types of radiation, radiative transfer are to utilize radiation between the object and absorb each other infrared rays, and needn't have any medium to reach the balance of heat.
The radiation conduction is the important heat transfer type of technological process after heat fused reaches among glass melter.Especially in the medium and high temperature stage, higher efficient is arranged, especially at the traditional design type of heating of large and medium-sized glass melter flame on liquid level, it is more important that radiative transfer just seems except pot furnace, electric melting furnace.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of high radiant refractory brick manufacture craft that is used for process furnace, improves the efficient of the radiative transfer of the refractory brick of making, save energy.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of high radiant refractory brick manufacture craft that is used for process furnace, comprise the brick body, and described brick dignity is provided with high radiation paint layer to the side of process furnace inner chamber; It is characterized in that described high radiant refractory brick manufacture craft comprises brick embryo spraying method and becomes two kinds of methods of brick spraying method, wherein, the concrete technology of brick embryo spraying method is: make the refractory brick idiosome according to common process earlier; Spray high radiation paint in brick dignity on the side of process furnace inner chamber then, last refractory brick is sent into process furnace after air-dry and is burnt till among air; Become the concrete technology of brick spraying method to be: the technology according to refractory brick is fired into refractory brick earlier; Then refractory brick is built by laying bricks or stones in process furnace; At last on the side of heating bore, spray high radiation paint, get final product with the furnace heating-up heating-up furnace at fire brick surface.
As preferably, the thickness of described high radiation paint layer is 0.25-0.5mm.
As preferably, the radiant ratio of described refractory brick is 85%～97%.
As preferably, described brick body is provided with concaveconvex structure on the side that is coated with high radiation paint layer.
As preferably, described concaveconvex structure further groove be shaped as circular arc or many terrace with edges shape.
The present invention sprays high radiation paint layer on the brick body of refractory brick, make the heat in the process furnace heat-processed give heating object by radiation delivery by this high radiation paint layer, has improved the efficient of radiative transfer, has saved the energy.
The refractory brick that the present invention makes has following advantage:
1, improve heat transfer efficiency, can save energy 8%---16%;
2, the black ceramic glaze wear resisting property of high radiation paint formation significantly improves;
3, high insulating effect;
4, long service life;
5, manufacturing process is simple.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is further described:
Fig. 1 is a firebrick structure synoptic diagram of the present invention.
Embodiment
Fig. 1 shows the concrete structure of high radiant refractory brick, and it comprises brick body 10, and at least one plane of described brick body is provided with high radiation paint layer.The thickness of described high radiation paint layer is 0.25-0.5mm.Described high radiation paint layer is located at brick dignity on the side of process furnace inner chamber.
Refractory brick of the present invention can also be done further improvement, is being coated with at described brick body on the side of high radiation paint layer and is being provided with concaveconvex structure 101.Described concaveconvex structure is arranged and is cellular, described concaveconvex structure further groove be shaped as circular arc or many terrace with edges shape.Increase the thermal radiation area like this, improved radiation efficiency.
High radiant refractory brick manufacture craft of the present invention comprises brick embryo spraying method and becomes two kinds of methods of brick spraying method that wherein, the concrete technology of brick embryo spraying method is: make the refractory brick idiosome according to common process earlier; Spray high radiation paint in brick dignity on the side of process furnace inner chamber then, last refractory brick is sent into process furnace after air-dry and is burnt till among air; Become the concrete technology of brick spraying method to be: the technology according to refractory brick is fired into refractory brick earlier; Then refractory brick is built by laying bricks or stones in process furnace; At last on the side of heating bore, spray high radiation paint, get final product with the furnace heating-up heating-up furnace at fire brick surface.
For the refractory brick that is provided with concaveconvex structure, can on the refractory brick idiosome, produce concaveconvex structure by mould in the brick embryo production phase, and then fire.
The novel refractory that high radiant refractory brick of the present invention is a kind of radiative transfer, its use on kiln will be started the new way of energy-saving and emission-reduction, adopt high radiant refractory brick with various process furnace and various saving energy in kiln 8%-16%.
