Description
Technical Field
The invention relates to a novel energy-saving high-temperature base plate.
Background
The high-temperature bearing plate is used for supporting a sintered blank. The main components of the traditional high-temperature base plate are mullite and cordierite, the refractoriness can reach 1350 ℃, and the appearance form of the base plate is generally that the bottom surface is a plane, and the upper surface is a plane or a granite surface (slight concave-convex exists to prevent the product from sliding on the upper surface). During firing, heat is transferred to the bottom of the product on the mat by providing high temperature at the bottom of the mat to burn the mat red (burn through). The heat conduction mode is a direct conduction mode, and the biggest defect of the mode is that the heat efficiency is low, so that the single energy consumption of the formed product is very high and is 30-50% lower than that of a product in a naked combustion state (the heat efficiency formed by directly conducting heat through heat radiation). However, for some blanks with lower green strength or special shapes, the blanks cannot be directly subjected to bare firing on a roller rod, and only can be subjected to semi-bare firing in a state of being supported by a backing plate, the bottom of a product is almost completely contacted with a high-temperature backing plate in the semi-bare firing state, the heating condition of the formed bottom is not only low in thermal efficiency, but also the phenomenon of deformation and even shrinkage cracking of the blank caused by inconsistent or asynchronous overall shrinkage of the blank is generated. Generally speaking, the traditional high-temperature backing plate has the advantages that the thermal efficiency is obviously lower than that of the traditional high-temperature backing plate in the process of firing, and meanwhile, great difficulty and risk are generated in the quality control of product firing, so that the rapid firing cannot be carried out, and the production cost of the product is higher.

Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The features and properties of the present invention are described in further detail below with reference to examples.
The first embodiment of the novel energy-saving high-temperature base plate of the invention:
the high-temperature backing plate of the embodiment is mainly explained by taking the high-temperature backing plate for producing the water permeable bricks as an example, and of course, the high-temperature backing plate claimed by the invention is not limited to the high-temperature backing plate used for producing the water permeable bricks, and can also be used for sintering other heat-resistant products.
As shown in fig. 1 to 3, the high-temperature shim plate of the present embodiment includes a heat-resistant plate body 1 and a protruding structure 10 formed on an upper surface of the heat-resistant plate body 1, and the heat-resistant plate body 1 and the protruding structure 10 may be made of a mullite-cordierite composite material, and have high heat resistance and thermal conductivity.
The quantity of the convex structures 10 is large, the convex structures 10 are distributed on the heat-resistant plate body 1 in a discrete and dense mode, the upper ends of the convex structures 10 are supporting ends and used for supporting the bottom of a sintered blank in use, the convex structures 10 are communicated at intervals to form a heat radiation convection channel, and heat on the heat-resistant plate body 1 can be transferred to the bottom of the sintered blank in a radiation convection mode through the heat radiation convection channel.
Specifically, in the present embodiment, the heat-resistant plate body 1 is a rectangular plate, and has a length of 640mm, a width of 320mm, and a thickness of 15 mm. The protruding structure 10 that sets up on it specifically is the round platform structure, and the height of round platform structure is 10mm, and the diameter of round platform structure up end is 10mm, and the lower terminal surface diameter is 14 mm.
The round platform structures on the heat-resistant plate body 1 are arranged in rows, the length direction of each row extends in the width direction of the rectangular plate, and the distance between the central lines of two adjacent rows is 18.6 mm. Referring to fig. 1 to 3, two rows at both ends of the heat-resistant mat 1 in the length direction are uniformly distributed rows 12. The distances between the two convex structures 10 at the two ends of the uniform distribution row 12 and the long edge of the corresponding side of the rectangular plate are equal and are both 5 mm; the distance between the bottom edges of the two uniformly distributed convex structures 10 at the two ends of the rectangular plate and the wide edge of the rectangular plate at the end where the bottom edges are located is 5 mm; the center distance between every two adjacent convex structures 10 in the uniform distribution row 12 is 18.5mm, and the bottom edge distance between every two adjacent convex structures 10 is 4.5 mm.
Each row between two rows 12 is called a staggered row 11, which is called a staggered row because the rows of protruding structures are arranged in a staggered manner in the length direction of the rectangular plate, and the protruding structures of each adjacent two rows correspond to the positions between two adjacent protruding structures of the other row in the length direction of the rectangular plate. In addition, one end of one row is close to the long edge of one side of the rectangular plate, and the other end of the other row is close to the long edge of the other side of the rectangular plate; dimensionally, the distance from the bottom edge of the protruding structure 10 at one end of the staggered row to the long edge of the rectangular plate at the corresponding side of the end is 5mm, and the distance from the bottom edge of the protruding structure 10 at the other end of the staggered row to the long edge of the rectangular plate at the corresponding side of the end is 13 mm.
When the high-temperature backing plate of this embodiment is adopted to sinter the water permeable brick, the sum of the areas of the upper end support ends of all the protruding structures occupies about 20% of the area of the upper surface of the heat-resistant plate body, two different heat transfer paths are formed at the bottom of the water permeable brick, namely, the heat-resistant plate body passes through the protruding structures to the sintered blank, and the heat-resistant plate body passes through the heat radiation convection channel to the water permeable brick blank, so that the water permeable brick blank can more quickly and effectively absorb the heat energy in the kiln, the heat loss is reduced, meanwhile, the bottom of the water permeable brick blank can be more uniformly heated, and the probability of shrinkage cracking and the like caused by uneven heating is greatly reduced. When the permeable brick is used, the permeable brick can be relatively quickly sintered, the production energy consumption cost is reduced, and the product quality is effectively improved.
