Problems solved by technology

However, most of the heat exchangers currently used are metal heat exchangers, and they can only be used at low temperatures. When the gas temperature is high, they cannot be used directly. A large amount of cold air must be mixed in, and high temperature protection is required, such as cold air machine and control system
When cold air is added, the temperature recovere

Example Embodiment

[0044] Example 1: Ceramic material and its production method

[0045] The production process steps include raw material selection and preparation, ball milling, filtration, mixing, mud smelting, staleness, scouring, extrusion molding, drying, sintering, finished product inspection, assembly and storage. The detailed steps are:

[0046] 1. Weigh mullite powder, cordierite powder, talc powder, clay powder, α-Al 2 O 3 As the matrix material component A, the weight percentages of various components in the matrix material are: 20% mullite powder, 40% cordierite powder, 10% talc powder, 10% clay powder, α-Al 2 O 3 20%;

[0047] Weigh mullite and cordierite as aggregate component B. The weight percentage of these two components in the aggregate is 16% for mullite with a particle size of 0~0.5mm, and 36 for mullite with a particle size of 0.5~1mm. %, the cordierite with a particle size of 0 to 0.5 mm is 34%, and the cordierite with a particle size of 0.5 to 1 mm is 14%. The weight ratio o...

Example Embodiment

[0056] The second embodiment: the ceramic material and its production method are basically the same as the first embodiment, and the similarities will not be described again. The differences are:

[0057] 1. Matrix material component A, mullite powder 40%, cordierite powder 20%, talc powder 20%, clay powder 10%, α-Al 2 O 3 The 10% matrix material has a particle size of 220 mesh.

[0058] In aggregate component B, mullite with a particle size of 0~0.5mm is 36%, mullite with a particle size of 0.5-1mm is 16%, cordierite with a particle size of 0~0.5mm is 14%, and cordierite with a particle size of 0.5-1mm Is 34%. The weight ratio of the two components A and B is 1:1, and 1% of the total weight of the two components A and B is added with a binding agent.

[0059] 2. Measure and weigh according to the formula of the matrix material, add water (the weight ratio of water to the matrix material is 1:3), and send it to a wet ball mill for grinding for 10-12 hours. The particle size after ...

Example Embodiment

[0062] The third embodiment: the ceramic material and its production method are basically the same as the first embodiment, and the similarities will not be described again. The differences are:

[0063] 1. Matrix material component A: 25% mullite powder, 25% cordierite powder, 30% talc powder, 10% clay powder, α-Al 2 O 3 10%;

[0064] In aggregate component B, mullite with a particle size of 0~0.5mm is 20%, mullite with a particle size of 0.5-1mm is 20%, cordierite with a particle size of 0~0.5mm is 30%, and cordierite with a particle size of 0.5-1mm Is 30%.

[0065] The weight ratio of the two components A and B is 1:1.5, and 0.8% of the total weight of the two components A and B is added with a binding agent.

[0066] 2. During sintering, the temperature is controlled at 1350℃, and it is sintered according to the conventional racking for 40h, keeping the temperature for 5h, and cooling to below 500℃ and out of the furnace.

[0067] Sintering temperature rise requirements, the t...

Abstract

The invention discloses a ceramic transducer, ceramic material and their preparing method. The ceramic material comprises base material a, skeletal material B and anchoring agent. The A comprises 20-40% mullite powder, 20-40% dichroite powder, 10-36% talcum powder, 10-30% pug powder, and 10-20%alpha-Al2O3 powder, and the B comprises 32-72% mullite and 28-68% dichroite; the proportion by weight of the A and B is 1-1.5:1-1-1.5. The method comprises the following steps: making a mud cake, adding B and anchoring agent, pugging, staling, shaping, drying and clinkering. The sintering temperature is 1300-1400Deg.C, and agglomeration time is 36-48 hours. The invention is suit for industrial production.

Description

[0001] 1. Technical field: The present invention relates to a heat exchanger, a refractory material and a production method thereof, in particular to a ceramic heat exchanger, a ceramic material and a production method thereof. 2. Background technology: [0002] The production and use of new high-efficiency and energy-saving ceramic heat exchangers that can meet the needs of various kilns has not yet been found, and the production technology of ceramic heat exchangers still remains at the development status of more than ten years ago. For example: (1) use high-alumina clinker and composite clay as raw materials to produce seamless integral structure tube-and-disc ceramic heat exchange tubes through the steps of kneading, molding, drying, and sintering; (2) use raw and cooked coke gemstones, soft Based on local raw materials such as high-quality clay, water-soluble organic polymers are used as binders, and cordierite-based high-temperature ceramic heat exchangers are artificiall...
