Abstract

The invention discloses a ceramic material for a mold. The ceramic material is prepared from, by mass, 10-13 parts of zirconia, 15-18 parts of calcium oxide, 8-10 parts of magnesium oxide, 15-20 partsof silicon carbide fine powder, 18-20 parts of bentonite, 1-2 parts of titanium carbide nano-powder, 6-8 parts of barium chromate, 3-4 parts of bismuth trioxide, 4-6 parts of barium sulfate, 8-10 parts of calcite in powder and 3-5 parts of adjuvant. The ceramic material has high wear resistance, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of mold materials, and in particular relates to a ceramic material for molds. Background technique [0002] Traditional alloy steel mold materials are all pure metal alloy materials. With the continuous development of the processing industry, the quality requirements for molds are getting higher and higher. Some enterprises use ceramic materials to prepare molds in order to maximize profits, but the existing ceramic materials The mold has a relatively short service life and poor wear resistance. Contents of the invention [0003] The object of the present invention is to provide a ceramic material for a mold, which can have good wear resistance and prolong the service life. [0004] In order to achieve the above object, the present invention provides a technical solution: a ceramic material for a mold, which comprises the following components in parts by mass: zirconia: 20-35 parts, calcium oxide: 15-18 p...
