Abstract
The invention relates to a cutting nozzle with a cutting nozzle, which consists of 2-8 percent of sturgeon oil and 92-98 percent of nanometer aluminum sesquioxide. A manufacture method is the following processes: the sturgeon oil is evenly mixed with the nanometer aluminum sesquioxide and the mixture is then put into a mold. After molded into a model of cutting nozzle by the pressure of 0.5-0.8MPa, the mixture is sintered for 13-14 hours under the high temperature of 1,600 DEG C to 1,700 DEG C and finally the mixture is naturally cooled for obtaining the product. In the invention, the cutting nozzle with a cutting nozzle adopts raw materials of the nanometer aluminum sesquioxide (the melting point of the aluminum sesquioxide is 2,050 DEG C) and simultaneously adding the sturgeon oil; therefore, the obtained cutting nozzle with a cutting nozzle has greatly improved high temperature resistant capacity and strength. The invention also has the advantages of prolonged service life and remarked lower production cost since the price of the aluminum sesquioxide is far below that of copper.
Description
Technical field
The present invention relates to a kind of conticaster cutting torch and preparation method thereof.
Background technology
The conticaster cutting torch that is used for the cutting of steel-making continuous casting base flame comprises inner core, shell, at present use wider conticaster cutting torch all to adopt metallic copper to be raw material mostly, because the fusing point of copper is that 1083.4 degree are lower, when carrying out the cutting of steel-making continuous casting base flame, cutting torch burns out easily, service life is very short, and the price factor of copper makes that the production cost of cutting torch is very high in addition.
Summary of the invention
Purpose of the present invention just provides a kind of long service life, conticaster cutting torch that production cost is low and preparation method thereof.
Conticaster cutting torch of the present invention is made up of following raw materials by weight percent:
Silicone oil 2-8%, nanoscale alundum (Al 92-98%.
Conticaster cutting torch preparation method of the present invention is: silicone oil and nanoscale aluminium oxide powder are mixed, pack in the mould, be compression molded into the cutting torch type with 0.5-0.8mpa pressure, afterwards, under 1600-1700 ℃ of high temperature sintering 12-14 hour, cooling got final product naturally then.
Conticaster cutting torch of the present invention is because raw material adopts nanoscale alundum (Al (2050 ℃ of the fusing points of alundum (Al), add silicone oil simultaneously, make conticaster cutting torch heat-resisting ability and the intensity made improve greatly, prolong service life, and the price of alundum (Al is well below copper, and production cost also significantly reduces.
