example 1

[0025] First, in parts by weight, successively take 160 parts of iron oxide, 20 parts of cryolite, 40 parts of silicon dioxide, 8 parts of potassium chlorate, 10 parts of carboxymethyl cellulose, and 8 parts of glycerin, pour them into a ball mill jar, press the Add zirconia ball milling beads at a mass ratio of 15:1. After ball milling and mixing for 2 hours, pass through a 120-mesh sieve to obtain a ball mill, and transfer the obtained ball mill to an oven, and dry it at a temperature of 105°C until it reaches a constant weight. Ball mill, then transfer the dry ball mill to the mixer, and add 25% of the mass of iron oxide to the mixer and add aluminum powder with a particle size of 120 mesh, stir and mix at 600r / min for 45min to obtain a mixed powder; then intercept a section For 45# hot-rolled seamless steel pipes with a length of 2m, an inner diameter of 76mm, and a wall thickness of 6mm, rinse the inner wall of the hot-rolled seamless steel pipe with 3% dilute hydrochloric...

Abstract

The invention discloses a preparation method for a metal glass composite pipe, which belongs to the technical field of preparation of composite pipes. According to the invention, a self-propagating aluminum thermal reaction of aluminum and iron oxide is taken as a processing technology; cryolite is added at first, so the reaction is allowed to be safely carried out in virtue of the dilution effect of cryolite, and the fluidity of a system is improved by using cryolite, thereby facilitating a fusion product to be evenly distributed on the inner wall of a hot-rolled seamless steel pipe under the action of centrifugal force; then a small amount of borax is added, which is favorable for discharging gas in the system in an adequate period of time, reducing the possibility of shrinkage formation, so the density of the inner wall of the product is improved and a smooth and bright glass layer is formed; finally, the inner wall of the hot-rolled seamless steel pipe is welded with the fusion product of the self-propagating aluminum thermal reaction, so good metallurgical bonding of the transition metal layer and the steel pipe is prepared; and thus, the metal glass composite pipe is prepared.

Description

technical field [0001] The invention discloses a method for preparing a metallic glass composite pipe, which belongs to the technical field of composite pipe preparation. Background technique [0002] Glass has the characteristics of low friction coefficient, excellent seizure resistance and high hardness. Using glass as an additive, metal matrix composites are prepared by powder metallurgy. Research and practical effects in this area have been reported in the 1980s. For example: use iron powder to add glass powder to make corrosion-resistant textile machine parts; use bronze-glass composite materials to manufacture self-lubricating bearings; the aluminum-glass composite materials developed by Kainer are twice as strong as the usual age-hardening aluminum alloys, and are wear-resistant It is nearly 100 times more resistant, and can be used for various cold and hot processing, welding and various surface treatments. Therefore, the metal-glass composite pipe is expected to be...
