BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Figure 1 It is a flow chart of a preferred embodiment of a method for preparing a wear-resistant ceramic tile in the present invention. DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] With the development of traditional industrial and mining industries and related regions, the amount of bulk solid waste generated has gradually increased, such as the amount of metallurgical slag generated. If these metallurgical slags cannot be effectively and efficiently utilized, it will bring huge resistance to the green upgrading and development of traditional industrial and mining industries. Therefore, it is of particular practical significance if large solid wastes such as metallurgical slag can be reasonably used to prepare wear-resistant ceramic tiles suitable for outdoor public occasions.

[0035] See also Figure 1 , Figure 1 1 is a flow chart of the method for preparing the wear-resistant ceramic tile of the present invention. Figure 1 As shown, the method for preparing the wear-resistant ceramic brick according to the embodiment of the present invention comprises the following steps:

[0036] Step S100, pressing the prepared ceramic tile powder and metal material into a composite ceramic body, wherein the raw material formula of the ceramic tile powder includes metallurgical slag;

[0037] Step S200, processing the composite ceramic body to obtain a wear-resistant ceramic tile; wherein the raw materials of the metallurgical slag include 55-70 parts by weight of vanadium-titanium slag and 10-20 parts of red mud.

[0038] Specifically, the embodiment of the present application is a method for preparing wear-resistant ceramic tiles suitable for outdoor public places using metallurgical slag, which solves the problem that the metallurgical slag used in the production of building ceramics does not match the traditional building ceramic body formula system. Through the high-temperature sintering process of building ceramic production, the harmful components in the metallurgical slag can be solidified, reducing the harm to the environment caused by the stacking of metallurgical slag, and improving the utilization rate of solid waste resources. In addition, the wettability problem of metal and non-metal phases in the process of metal phase reinforcement and toughening building ceramics is solved. Since the building ceramic formula adjusted by metallurgical slag contains a large amount of metal phases and metal oxides, the matching problem of the traditional ceramic formula system and the wettability of metal materials can be solved, thereby preparing ceramic products with better performance and better quality.

[0039] In addition, the multi-component phase composition in the metallurgical slag can shorten the firing time of the composite ceramic tile and reduce the firing temperature, thus solving the problem of long firing time and high firing temperature of traditional ceramics. 2 O 3 The mass percentage of the metal oxide is greater than 35%, and the sum of the mass percentages of other metal oxides is greater than 5%.

[0040] In the embodiment of the present application, the chemical components of the vanadium-titanium slag are calculated by mass percentage, including: ignition loss 1% to 1.5%, Al 2 O 3 3.5%~5%, SiO 2 12%~20%,Fe 2 O 3 40%~50%, CaO2%~4%, MgO 2.5%~4%, K 2 O 0.01%~0.05%, Na 2 O 3.5%~6%, TiO 2 9%~15%, MnO 7%~12%, Cr 2 O 3 2%~6%,V 2 O 5 0.5%~2%.

[0041] Specifically, vanadium-titanium slag is a smelting waste slag containing vanadium and titanium, which mainly comes from the steelmaking and ironmaking processes. The embodiment of the present application utilizes a large amount of metallurgical slag to prepare ceramic bricks, which can greatly reduce the environmental pollution problems caused by the stacking of metallurgical slag and realize the utilization of solid waste.

[0042] In one embodiment of the present application, the chemical components of the red mud, by mass percentage, include: loss on ignition 8% to 12%, Al 2 O 3 18.5%~23%, SiO2 12.5%~18.5%,Fe 2 O 3 30.5%~40%, CaO 4.5%~6.5%, MgO 0.1%~0.5%, K 2 O 0.1%~1%, Na 2 O5%~8%, TiO 2 3%~6%.

[0043] Specifically, red mud is an industrial solid waste discharged when the aluminum industry extracts alumina, and contains a large amount of iron oxide.

[0044] The metallurgical slag used in the embodiments of the present application is mainly metallurgical slag with a high iron content such as vanadium-titanium slag and red mud, which contains a large amount of metal oxides, especially a high iron oxide content. The metal material is iron, steel or alloy steel mainly composed of iron elements. There is good compatibility between the metallurgical slag and the metal material. Therefore, when the metallurgical slag is co-fired with the metal material mainly composed of iron, the wettability problem between the metallurgical slag and the metal material can be effectively improved.

[0045] In the embodiment of the present application, the physical phases of the vanadium-titanium slag include: hematite, ferromanganese spinel, ilmenite, magnesia-iron titanite, clinovanadium titanite and rutile.

[0046] Specifically, the vanadium-titanium slag phase composition is: hematite (Fe 2 O 3 ), hematite (containing chromium) (Fe 0.6 Cr 0.4 ) 2 O 3 、Manganese iron spinel MnFe 2 O 4 、ilmeniteFe +2 TiO 3 、Mg, Fe (Ti 3 Fe)O 10 , vanadium titanium ore V 2 +3 Ti 3 O 9 And a small amount of rutile TiO 2 .

[0047] The vanadium-titanium slag of the embodiment of the present application contains a large number of different types of crystal phases, and the glass phase content is greatly reduced, which makes the metallurgical slag contain a large number of different types of crystal phases, and the glass phase content is also greatly reduced. In this way, various crystal phases are intertwined and connected with each other during the high-temperature firing process, thereby improving the strength and toughness of the ceramic product. It solves the problems of high marble cost and easy wear and discoloration of ceramic tile surface, low strength and easy breakage when traditional ceramics are used in places with high traffic such as subway stations, squares, and shopping malls.

[0048] In the embodiment of the present application, the raw material formula of the ceramic tile powder includes, by weight: 13 to 20 parts of ball clay, 1 to 5 parts of bentonite, 1 to 7 parts of black talc, 70 to 80 parts of metallurgical slag, and 0.3 to 0.5 parts of green body disintegrator.

[0049] Specifically, the ceramic tile powder is obtained by grinding the raw materials in the raw material formula into a ball mill through a feeder according to the formula ratio after aging and homogenization to obtain a slurry that meets the fineness requirements. The slurry is sieved, aged, and impurity-removed, and then spray-dried to obtain the ceramic tile powder.

[0050] The green body disintegrator comprises one or more of a composite diluent, sodium tripolyphosphate, sodium pentametaphosphate, sodium humate and water glass.

[0051] In the embodiment of the present application, the chemical components of the ceramic tile powder are calculated by weight and include:

[0052] SiO 2 25-35 parts, Al 2 O 3 5~15 pieces, K 2 O 0.5~2 parts, Na 2 O 1-6 parts, CaO 1-3 parts, MgO 1.5-3.5 parts, TiO 2 7.5-11 parts, Fe 2 O 3 25~40 parts, Cr 2 O 3 2.5-3.5 parts, MnO 4.5-7 parts.

[0053] In the embodiment of the present application, the metal material is a metal wire; the prepared ceramic tile powder and the metal material are pressed into a composite ceramic body, comprising:

[0054] Laying a first powder layer using the prepared ceramic tile powder, and laying metal wires on the first powder layer to obtain a metal wire layer;

[0055] Laying a second powder layer on the metal wire layer using the prepared ceramic tile powder;

[0056] The first powder layer, the metal wire layer and the second powder layer are pressed into a composite ceramic body.

[0057] Specifically, when the metal material of the embodiment of the present application is a metal wire, a multi-layer cloth method is adopted. First, a layer of ceramic tile powder is laid, then the metal wire is laid, and finally another layer of ceramic tile powder is laid, and a press is used to press it into a composite ceramic body. The metal wire is an iron wire, a carbon steel wire or an alloy steel wire, and the alloy steel wire is mainly an alloy steel wire containing metal elements such as manganese, titanium, chromium, silicon, and aluminum. The diameter of the metal wire is 0.1 to 1 mm. When using metal wire, the distribution of the metal wire adopts a criss-cross laying method, and the laying density is 4 to 25 holes per square centimeter of area. The laying length and width need to reserve the length of the blank sintering shrinkage. For example, when the blank is sintered and shrunk by 8‰, the laying range of the metal wire needs to be 8‰ shorter than the four sides of the pressing mold to ensure that the metal wire will not be exposed due to the shrinkage of the blank during firing.

[0058] The metallurgical slag used in the embodiment of the present application is mainly metallurgical slag with high iron content such as vanadium-titanium slag and red mud, which contains a large amount of metal oxides, especially high iron oxide content, and the metal wire is iron wire, steel wire, and alloy steel wire mainly composed of iron elements. The two have good compatibility, so when the metallurgical slag is co-fired with the metal wire mainly composed of iron, the wettability problem of the metallurgical slag and the metal wire can be effectively improved. The difficulty in preparing metal ceramics lies in the wetting problem of the metal phase and the non-metal phase. Therefore, by utilizing the characteristics of these components in the metallurgical slag, metal-non-metal composite ceramics with better effects can be prepared. Ceramics with added metal materials can greatly improve their toughness and increase their elastic limit. At the same time, since the metallurgical slag contains a large number of different types of crystal phases, the glass phase content is greatly reduced, so that the various crystal phases of the ceramic formula system are interlaced and connected during the high-temperature firing process, thereby improving the strength and toughness of the ceramic product. The preparation process of the whole body is used to prepare ceramic products, so that it can be used in outdoor places for a long time without discoloration, thereby improving its durability.

[0059] In another embodiment of the present application, the metal material is metal fiber; the prepared ceramic tile powder and the metal material are pressed into a composite ceramic body, comprising:

[0060] The prepared ceramic tile powder and metal fiber are mixed and pressed to obtain a composite ceramic body, wherein the metal fiber accounts for 0.5% to 5% of the ceramic tile powder by weight;

[0061] Wherein, the aspect ratio of the metal fiber is 1 to 10, and the length of the metal fiber is 0.1 to 2 mm.

[0062] Specifically, the metal fiber is iron fiber, carbon steel fiber, alloy steel fiber, and the alloy steel fiber is mainly alloy steel fiber containing metal elements such as manganese, titanium, chromium, and aluminum.

[0063] The diameter of the metal fiber is 0.1-1 mm. When the metal fiber is used, the metal fiber needs to be mixed and pressed together with the ceramic brick powder, the aspect ratio of the metal fiber is 1-10, and the length of the metal fiber is 0.1-2 mm.

[0064] The metallurgical slag used in the embodiments of the present application is mainly metallurgical slag with high iron content such as vanadium-titanium slag and red mud, which contains a large amount of metal oxides, especially high iron oxide content, and the metal fiber is iron fiber, steel fiber, and alloy steel fiber mainly composed of iron elements. The two have good compatibility, so when the metallurgical slag is co-fired with the metal fiber mainly composed of iron, the wettability problem of the metallurgical slag and the metal fiber can be effectively improved. The difficulty in preparing metal ceramics lies in the wetting problem of the metal phase and the non-metal phase. Therefore, by utilizing the characteristics of these components in the metallurgical slag, metal-non-metal composite ceramics with better effects can be prepared. Ceramics with added metal materials can greatly improve their toughness and increase their elastic limit. At the same time, since the metallurgical slag contains a large number of different types of crystalline phases, the glass phase content is greatly reduced, so that the various crystalline phases of the ceramic formula system are interlaced and connected during the high-temperature firing process, thereby improving the strength and toughness of the ceramic product. The preparation process of the whole body is used to prepare ceramic products, so that it can be used in outdoor places for a long time without discoloration, thereby improving its durability.

[0065] In one embodiment of the present application, the composite ceramic body is processed to obtain a wear-resistant ceramic tile, comprising:

[0066] Drying the composite ceramic body, and sending the dried composite ceramic body into a roller kiln for sintering to obtain a wear-resistant ceramic tile;

[0067] The sintering time is between room temperature and 700°C for 15 to 25 minutes, the sintering time is between 700°C and 1050°C for 8 to 15 minutes, and the sintering time is kept at 1050°C for 3 to 6 minutes.

[0068] Specifically, the composite ceramic body is dried in a drying kiln to obtain a body with a certain strength; the body is sent to a roller kiln for firing to obtain a sintered ceramic product. The surface of the product out of the kiln is polished, and then it is edged, chamfered, air-dried, inspected, color-separated, and graded before being packaged and stored. The water absorption rate of the finished product is less than 0.1%.

[0069] The sintering time in the high-temperature section of the embodiment of the present application is relatively short during the sintering process. Since the formula system of the present application contains less organic matter and less burn-off, and the formula system contains a large amount of crystal structure, favorable conditions are provided for low-temperature fast sintering. At the same time, the sintering time in the high-temperature section is reduced, and the oxidation of the metal phase can be avoided, thereby ensuring the performance of the product.

[0070] The present invention can prepare a steel sheet with a strength of more than 80 MPa and a wear volume of less than 100 mm by using the above formulation system and preparation method.3 , wear-resistant ceramic tiles with an elastic limit greater than 18 mm when the thickness is 6 mm, and the wear-resistant ceramic tiles are suitable for outdoor ground places with large traffic flow such as subways and squares.

[0071] The embodiments of the present application achieve the following effects:

[0072] First, the ceramic tiles prepared in the embodiments of the present application have high strength, good toughness and good wear resistance, which solves the problem that the marble currently used for the ground in subways, stations, squares, etc. is relatively expensive, while the fully glazed ceramic products have poor wear resistance.

[0073] Second, the embodiments of the present application utilize a large amount of metallurgical slag to prepare ceramic tiles, which can greatly reduce the environmental pollution problems caused by the stacking of metallurgical slag and realize the utilization of solid waste.

[0074] Third, the embodiment of the present application utilizes the composition characteristics of metallurgical slag, changes the traditional ceramic formulation system based on mullite crystal phase, and proposes a polycrystalline composite ceramic formulation system. The prepared ceramics have good toughness and high strength, with a strength greater than 80MPa, while the strength of traditional ceramics is only about 40MPa.

[0075] Fourth, the embodiments of the present application utilize the characteristics of metallurgical slag with more crystal phases and less burning loss, which can significantly reduce the sintering temperature and sintering time of ceramics, thereby greatly reducing energy consumption and providing a new direction for the low-carbon development of building ceramics.

[0076] Fifth, the embodiments of the present application utilize the composition characteristics of metallurgical slag to solve the wettability problem of the metal phase and the non-metal phase, thereby providing basic conditions for metal phase reinforcement and toughening of building ceramics. Metal-nonmetal composite ceramic tiles with high strength and good toughness can be prepared, thereby improving the toughness of ceramic tiles and enhancing the quality and market competitiveness of ceramic products.
