Problems solved by technology
However, the existing industrial cermets have an impact resistance value of 1.5-2.0 joules and are extremely easy to break. In order to solve the above problems, a new type of industrial ceramic material has been specially developed, and its ceramic impact resistance value can reach 6.5-7.7 joules. It meets a certain impact resistance value and compressive strength, and solves the problem of low impact resistance and compressive strength of industrial ceramics and is easy to break.

Embodiment Construction
[0011] The following is a description of a new type of elbow pipe fittings for concrete pump truck booms made of a new type of industrial ceramic material as an example.
[0012] The first step: Add 15% high-temperature resin glue to the gypsum powder, mix and stir evenly, and then send it to a high-temperature environment of 180°C-200°C through a conveyor belt for film coating, and then shoot the molding machine for mold shell molding after film coating;
[0013] Step 2: After the molding machine is finished, the mold shell is put into a professional tooling mold, and the core shooting machine is pressurized and molded again;
[0014] The third part: the mixed material composed of 5% zirconia, 2.5% yttrium oxide, 12% nickel oxide and 80.5% aluminum oxide is stirred by a high-speed mixer to synthesize a ceramic mixed material;
[0015] Step 4: Spray and stir the mixed ceramic material on the mold shell in the core shooter, and pre-fire at a high temperature of 900°C-1050°C for...

The invention discloses a novel ceramic material for industrial use, and a manufacturing process of the novel ceramic material. The manufacturing process is mainly characterized in that the novel ceramic material for industrial use is prepared by combining a firing process used in ceramic production with a film-coated sand process used in manufacturing of cast iron by using a new formula; the novel ceramic material contains zirconia, yttria, nickel oxide powder and alumina; the manufacturing process comprises the steps of firstly, adding high-temperature resin adhesive into gypsum powder for coating by using the film-coated sand process used in manufacturing of the cast iron; then, shaping by using an edge-emitting machine; after the shaping is completed, putting a mold shell into a professional tooling mold, pressurizing by using a core shooting machine, spraying a ceramic mixture, and heating the ceramic mixture in a mold up to 900-1050 DEG C; pre-burning for two minutes, and then carrying out mold stripping; after mold stripping is finished, cooling the product together with the mold, then firing in a baking furnace which can heat up to 1900 DEG C from a constant temperature, and cooling; the process consumes 8 hours in total. The novel ceramic production process is simple and low in manufacturing cost, and greatly improves the stability and safety of the novel ceramic material for industrial use during work and operation.
Description
technical field [0001] The invention discloses a ceramic material, in particular to the field of a novel industrial ceramic material and a manufacturing process. Background technique [0002] With the rapid development of modern industrial ceramic technology, industrial ceramics have been widely used and are indispensable for various engineering, mechanical equipment, pipelines and other components. However, the existing industrial cermets have an impact resistance value of 1.5-2.0 joules and are extremely easy to break. In order to solve the above problems, a new type of industrial ceramic material has been specially developed, and its ceramic impact resistance value can reach 6.5-7.7 joules. It meets a certain impact resistance value and compressive strength, and solves the problem of low impact resistance and compressive strength of industrial ceramics and is easy to break. Contents of the invention [0003] The technical problem to be solved by the present invention i...
