Embodiment 1

[0018] Embodiment 1 A kind of preparation method of tempered ceramics

[0019] The technical solution adopted by the present invention is: the raw materials and the preparation method comprising the following parts by weight:

[0020] Raw material formula

[0021] Coal gangue: 99kg

[0022] Neodymium oxide: 0.1kg

[0023] Cerium oxide: 0.1kg

[0024] The preparation method is as follows:

[0025] (1) The pulverizing machine makes coal gangue into 80-mesh fine powder and sends it into the powder bin, and the pulverizing machine sends it into the primary plasma burner for high-temperature gasification and combustion, decarburization, and enters the boiler liquefaction chamber. The combustible gas enters the combustion chamber of the boiler to fully burn the combustible gas, and the generated steam enters the drum and then goes to the generator set;

[0026] (2) The flue gas generated by combustion enters the denitrification device and is taken away by the induced draft ...

Abstract

The invention relates to a preparation method and a preparation device of toughened ceramic, which belong to the field of toughened ceramic. The toughened ceramic comprises the following materials in parts by weight: 99-100 parts of coal gangues, 0.1-5 parts of neodymium oxide and 0.1-8 parts of cerium oxide. The preparation method and the preparation device of toughened ceramic are the production method and the production device of toughened ceramic for carrying out deoxidation and nitridation on aluminum silicon oxide and other ingredients in the coal gangues and converting the aluminum silicon oxide and the other components into aluminum silicon nitride. The preparation method and the preparation device of the toughened ceramic are combination for producing toughened ceramic by virtue of coal gangue power generation and coal gangue liquid, so that heat energy generated in the coal gangue liquefying process is utilized for generating power, and therefore, the energy resources are saved and low-cost production is realized.

Description

technical field [0001] The invention belongs to a preparation method and device of tempered ceramics. Background technique [0002] The calorific value of coal gangue is generally 800-2800 cal / g, and its inorganic components are mainly oxides of silicon, aluminum, calcium, magnesium, iron, vanadium and some rare metals, and the percentage of its inorganic components: SiO 2 52-65; Al 2 o 3 16-46; Fe 2 o 3 0.03~14.63; CaO 0.42~2.32; MgO 0.44~2.41; TiO 2 0.90~4;P 2 o 5 0.007~0.24; K 2 O+Na 2 O is 1.45~3.9; V 2 o 5 0.008 to 0.03. [0003] At present, the physical and chemical characteristics and special properties of tempered ceramics have been recognized by people. There are many production methods for tempered ceramics, but the problem of high cost and high energy consumption has not been solved. At present, there is no deoxidation and nitrogen replacement using mineral components in coal gangue. method. Contents of the invention [0004] The invention provides ...
