Definitions
- the invention relates to the construction of linings and arches of heat engineering units for mechanical engineering and can find application in the construction of industrial furnaces in the metallurgical, heat power, oil refining and petrochemical industries, in the production of building materials and other industries.
- State of the art
- the invention is known according to the USSR AS 1354020, IPC F27D 1 1/02.
- brackets with blocks of solid ceramic material are fixed to the casing, hooks are installed in the holes of the blocks, blocks of soft fibrous heat-insulating material are laid, piercing them on the pointed branches of the hooks.
- intermediate supports for example, ceramic tubes, are laid parallel to the walls of the casing, fixing the hooks relative to the latter with brackets. Heating elements are hung on hooks and include an electric furnace.
- the disadvantages of the electric furnace are the insufficient structural strength due to the use of additional structural and fastening elements, the presence of metal fasteners, which are thermal shunts.
- a panel made of heat-resistant concrete contains a layer of concrete, a reinforcing mesh with embedded parts for fastening panels that have a longitudinal hollow in the upper base and a longitudinal protrusion on the lower base, moreover, the hollow of the upper base corresponds to the protrusion of the lower base and vice versa, a longitudinal recess is made at the ends of the panel, in addition, a reinforcing mesh with fixed elements embedded in it is located in the concrete layer.
- the design drawback is that the panel has a reinforcing mesh with embedded elements in the body of heat-resistant concrete, which leads to the formation of a thermal shunt to the outside and increases the breaking stresses in concrete during thermal shifts.
- the use of a monolithic panel leads to the need to increase the insulation thickness to significant values, which significantly increases the external dimensions of the furnace.
- the objective of the invention is to obtain a durable refractory lining of resistance furnaces with low energy consumption and reducing the weight and dimensions of the furnace.
- the technical result of the invention is an increase in the strength of the refractory lining of resistance furnaces, a decrease in energy consumption, weight and dimensions of the furnace.
- the resistance furnace chamber made of refractory phosphate concrete contains blocks interconnected with the frame.
- the monolithic heat-insulating block is made of two square elements, diagonally shifted relative to each other, forming all the faces of the block in the form of a step for connecting to each other in a "castle".
- the thermal block is made in the form of a monolithic square element, in which the holes for the mounting studs are made, and each of the studs attaches one thermal block with external and internal heat-insulating blocks to the external metal frame of the furnace.
- the furnace vault is made of one row of monolithic heat-insulating central blocks and two rows of monolithic heat-insulating support blocks, the lower row of which is connected to a monolithic heat-insulating block having a semi-cylindrical surface on the upper inner face.
- the end parts of the monolithic heat-insulating support blocks are made semi-cylindrical and connected to the semi-cylindrical recesses made at the ends of the monolithic heat-insulating central block.
- the lateral faces of the monolithic heat-insulating support blocks are made in the form of a step and are interconnected into a “castle”. Studs are integrated into the monolithic heat-insulating central blocks, which extend onto the outer surface of the blocks and are used for fastening to the outer metal frame of the furnace.
- each hairpin attaches one heat block and two monolithic heat-insulating blocks to the external metal hearth frame.
- FIG. 1 - shows the insulating block.
- FIG. 2 structural element of the wall of the chamber furnace.
- FIG. 3 design of the arch of the chamber furnace.
- FIG. 4 - is shown under the chamber furnace.
- FIG. 5 is a general view of the design of a chamber furnace.
- the monolithic heat-insulating block 1 (Fig. 1) is made of two square elements, diagonally shifted relative to each other, forming all the faces of the block in the form of a step 2 for connection to each other in a "castle".
- the main heat-insulating material is an air layer enclosed between two monolithic heat-insulating blocks 1.
- the thermal block 8 is made in the form of a monolithic square element, which has two round holes 9 for the mounting stud 6.
- the arch (FIG. 3) is made of one row of monolithic heat-insulating central blocks 10, two rows of monolithic heat-insulating support blocks 11, the lower row of which is connected to a monolithic heat-insulating block 1 having a semi-cylindrical surface 12 on the upper inner face.
- the monolithic heat-insulating support blocks 1 1 comprise a semi-cylindrical end part 13 for connection with a semicylindrical recess 14 of the monolithic heat-insulating central block 10 and half-cylindrical protrusions 15 on the lower part of the surface of the monolithic heat-insulating support block 11.
- the monolithic heat-insulating support blocks 11 have lateral faces made in the form of a step 16 , and are interconnected in a "castle.”
- the monolithic heat-insulating central blocks 10 have two half-cylindrical recesses 14 from the ends for connection with two rows of monolithic heat-insulating support blocks 11 and side faces 17 made in the form of a step for connecting to each other.
- the monolithic heat-insulating central blocks 10 have built-in studs 18, which extend onto the outer surface of the blocks and are intended for fastening to the outer metal frame of the furnace.
- the mounting stud is not a thermal shunt, since the threaded metal stud is insulated with the refractory phosphate concrete of which the stud is made, with on the other hand, it provides a tight gas-tight connection to the heat block.
- the hearth lining design (Fig. 4) of the furnace is made of two rows of monolithic heat-insulating blocks 1, interconnected “in the lock”, and one row of thermal blocks 8, which are attached with pins 6 to the outer metal hearth frame. Washers are not used in the hearth design.
- the strength of the compression hearth is not lower than 50 MPa.
- all parts of the lining are made of monolithic blocks of high-strength refractory non-conductive phosphate concrete and are used as structural bearing elements. They are used in resistance furnaces with a working temperature of up to 1000 ° C.
- the surface cleanliness of the blocks is not lower than 0.63, which provides them with a tight connection with the occurrence of ionic bonds and excludes the use of sealing materials in the form of a solution or soft refractory cords.
- the invention can find application in the construction of industrial furnaces in the metallurgical, heat power, oil refining and petrochemical industries, in the production of building materials and other industries.
