Embodiment 1

[0007] The composition of the ceramic ring is 92% by weight of alumina, 6% by weight of a mixture of niobium oxide and lanthanum oxide or magnesium oxide or calcium oxide or ytterbium oxide, or niobium oxide and lanthanum oxide, magnesium oxide, calcium oxide, One of any two-component composition or one of any three-component composition or four-component composition in ytterbium oxide, wherein niobium oxide and lanthanum oxide are added at the same time, and the ratio between them is arbitrary Ratio, the proportioning relationship of other compositions is also arbitrary proportioning, and 2% (weight) adhesive.

[0008] The manufacturing method is to mix the components and add water, put them into a ball mill, grind and stir to make a slurry, and then use hot die-casting technology to make a blank, put it in a high-temperature furnace to grind and sinter to form a blank, and then grind and polish on a machine tool. Make it meet the standard size and requirements.

Abstract

The present invention is one kind of ceramic ring superior to available metal ring, which has short service life and needs frequent replacement. The ceramic ring consists of alumina in 92-99 wt%, any combination of oxide of Nb, La, Mg, Ca and Yb in 0.5-6 wt% and adhesive in 0.5-2 wt%. It has the advantages of long service life, low end breakage rate, high thread line quality, etc.

Description

technical field [0001] The invention relates to a textile machinery accessory, in particular to a ceramic steel ring. Background technique [0002] Steel rings are key components on spinning frames in the textile machinery industry. Its function is to support the steel ring to complete the twisting and winding of the thread. At present, the materials used as steel rings are all metal materials, and its service life is short, only having three months to half a year. Not only does it increase the cost burden for the user, but also when replacing the steel ring, it must be stopped for disassembly and assembly, thus affecting production. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art, and provide a ceramic steel ring with long service life, significantly reduced yarn breakage rate, good thread quality, low labor intensity of workers and high production capacity. [0004] The present invention is achie...
