Abstract
The invention discloses a preparation method for a centrifugal self-propagating ceramic/alloy double-compound wear-resistant tube. The preparation method comprises the following steps of: performing sandblast derusting and roughening treatments on the inner surface of a steel tube; placing the self-propagating powder of Al+Fe2O3 system in the steel tube; placing the steel tube on a centrifugal machine, starting the centrifugal machine, and igniting to cause a self-propagating reaction after the rotational speed is stable; pouring melted wear-resistant alloy in the composite steel tube with an Al2O3 ceramic lining when an Al2O3 ceramic lining layer in the steel tube is in a semi-condensed state; coating the melted wear-resistant alloy on the Al2O3 ceramic coating to form a wear-resistant alloy layer under the action of a centrifugal force; then forming the ceramic/alloy double-compound wear-resistant tube. The preparation method disclosed by the invention is simple in process; the manufactured product is strong in wear resistance and corrosion resistance.
Description
Technical field
The present invention relates to a kind of centrifugal preparation method from spreading pottery/alloy double composite wear-resistant tube.
Background technology
In industrialization of the country construction process, need a large amount of abrasion-proof pipes to be used for transporting the resources such as ore, oil.Because stupalith has the characteristics such as wear resistant corrosion resistant is high temperature resistant, the lining coating of Chang Zuowei stainless steel tube, form ceramic-lined composite steel tube.
Industrial composite pipe with ceramic lining commonly used has several as follows at present: paster wear-resistant pipe, spot welding assembling caliper type wear-resistant pipe, centrifugal from spreading composite pipe with ceramic lining.The alumina ceramic plate that the paster wear-resistant pipe adopts viscose glue will have radian sticks on inner-walls of duct, forms the pipeline wearing layer.This kind of abrasion-proof pipe manufacture craft is simple, and wear resisting property is better, but alumina ceramic plate relies on viscose glue to be connected with the pipeline matrix, and bonding strength is not high, and environment for use is no more than 150 ℃ usually, and fabrication cycle is long, and these have all limited the application of paster wear-resistant pipe.Spot welding assembling caliper type wear-resistant pipe is to utilize high temperature resistant powerful viscose glue that the alumina ceramic plate of middle with hole is sticked on to inner-walls of duct, and the points of engagement Welding sees through aperture pottery is welded on to steel pipe inner wall securely simultaneously.For the protection solder joint, the above screws on the pottery block again.This kind of production technique has increased the bonding strength of pottery with the pipeline matrix, but the technique relative complex, fabrication cycle is longer, and cost is higher.All relate to artificial subsides porcelain in the manufacturing processed of paster wear-resistant pipe and spot welding assembling caliper type wear-resistant pipe, so the diameter of the abrasion-proof pipe of made is usually larger, the production of small-bore abrasion-proof pipe in being not suitable for.Centrifugal is the composite pipe that adopts " synthesize-high-speed centrifugation technology of self propagating high temperature " to manufacture from spreading composite pipe with ceramic lining, form ceramic layer and the transition layer of even thickness under high temperature and high speed, the manufacture of small-bore wear-resistant pipe in being applicable to, and, under the working temperature of 850-900 ℃, pottery still can not drop.In the serious wear industries such as straight tube, elbow, bend pipe, threeway, result of use is very good.But, because self-propagating reaction usually completed and reacts comparatively violent in several seconds, the gas in ceramic droplet is difficult to get rid of, and causes the ceramic coating surface pore more, the wear-resisting and erosion resistance of wear-resistant pipe is had to certain influence.
Summary of the invention
The object of the present invention is to provide a kind of technique simple, the centrifugal preparation method from spreading pottery/alloy double composite wear-resistant tube that the product of manufacture is wear-resisting, solidity to corrosion is strong.
Technical solution of the present invention is:
A kind of centrifugal preparation method from spreading pottery/alloy double composite wear-resistant tube, is characterized in that: comprise the following steps: steel pipe internal-surface is carried out to derusting by sandblast, roughening treatment; By Al+Fe
2o
3certainly the powder that spreads of system is put into steel pipe; Steel pipe is placed on whizzer, starts whizzer, after stabilization of speed, igniting causes self-propagating reaction; Treat the Al of steel duct

2o
3in ceramic-lined composite steel tube, make the wear resistant alloy of melting under the effect of centrifugal force, be coated on Al
2o
3form wear-resistant alloy layer on ceramic coating, form pottery/alloy double composite wear-resistant tube.
Described wear resistant alloy is low melting point wear resistant alloy Fe50 or TN-62.
The present invention adopts and to carry out the coating of low melting point wear resistant alloy at ceramic lining under the state in partly solidifying, and prevents the ceramic layer cracking that is heated; At ceramic lining surface-coated low melting point wear-resistant alloy layer, can make hole and the crackle on the alloy fill ceramic coating surface of melting on the one hand, improve the erosion resistance of multiple-unit tube, on the other hand, can greatly improve the centrifugal wear resisting property from spreading composite pipe with ceramic lining of tradition, extend the work-ing life of multiple-unit tube.Present method is simply effective, workable, prepared in small-bore pottery/alloy double composite wear-resistant tube can be applicable to the fields such as electric power, mine, chemical industry.
