Abstract
The invention discloses a structure for enhancing the strength of a centrifugal self-propagating ceramic-lined composite steel pipe. The structure comprises a steel pipe. Grooves are formed in the inner surface of the steel pipe, and an Al<2>O<3> ceramic lining which is formed by means of self-propagating reaction is lined in the inner surface of the steel pipe; the grooves which are formed in the inner surface of the steel pipe are combinations of spiral grooves and rectangular straight slots and comprise the 4-8 rectangular straight slots and the spiral grooves, the rectangular straight slots are formed in the circumference of the steel pipe, and the spiral grooves are formed in positions along the direction of the center line of the steel pipe and have left-handed or right-handed rotation directions. The structure has the advantages that the structure is reasonable, the grooves are formed in the inner surface of the steel pipe, accordingly, the contact areas of ceramic coatings and a matrix can be enlarged, and the compressive and shear strength of the ceramic coatings of the traditional centrifugal self-propagating ceramic-lined composite steel pipe can be improved; ceramic coating portions deeply extend into the grooves, so that excellent impact-resistant effects can be realized by the ceramic-lined composite steel pipe, and the coatings can be effectively prevented from falling off from the matrix.
Description
The divisional application that the application is application number 201310306450.9, the applying date: 2013.7.22, title " strengthens structure and the preparation method of centrifugal self-propagating ceramic-lined composite steel tube intensity ".
Technical field
The present invention relates to a kind of structure strengthening centrifugal self-propagating ceramic-lined composite steel tube intensity, belong to field of surface engineering technique.
Background technique
In industrialization of the country construction process, need the resources such as a large amount of ores, oil, pipeline transport, as the cost-effective long distance delivery instrument of one, occupies critical role in national economic development.Because the resources such as transported oil and ore have corrosion and percussion usually to delivering pipe, common steel pipe cannot reach the wear-resisting and decay resistance that transport point needs.
Stupalith has the features such as wear-resisting, corrosion-resistant, high temperature resistant, often it can be used as the inside liner of Stainless Steel Tube, is made into ceramic-lined composite steel tube for the wear-resisting field of pipeline.Pottery and common steel tube compound in, researcher have employed multiple method.Paster wear-resistant pipe is industrial comparatively common a kind of abrasion-proof pipe, namely adopts viscose glue that the alumina ceramic plate with radian is pasted onto inner-walls of duct, forms pipeline wearing layer.This kind of abrasion-proof pipe preparation process is simple, and wear-resisting property is better, but alumina ceramic plate and pipeline matrix rely on viscose glue to be connected, and adhesive strength is not high, and fabrication cycle is long, and these all limit the application of paster wear-resistant pipe.Spot welding assembling caliper type wear-resistant pipe utilizes high temperature resistant tenacity viscose that the alumina ceramic plate of middle with hole is pasted onto inner-walls of duct, and pottery is welded on steel pipe inner wall through aperture by points of engagement Welding securely simultaneously.For protection solder joint, screw on pottery block above again.This kind of production technique adds somewhat to the adhesive strength of pottery and pipeline matrix, but pottery still mainly relies on viscose glue with the combination of matrix, and adhesive strength is limited.In addition, all relate to and manually paste porcelain in the manufacture process of paster wear-resistant pipe and spot welding assembling caliper type wear-resistant pipe, the diameter of therefore made abrasion-proof pipe is usually comparatively large, the production of small-bore abrasion-proof pipe in being not suitable for.
Centrifugal self-propagating composite pipe with ceramic lining is the composite pipe adopting " SHS process-high-speed centrifugation technology " to manufacture.This kind of method technique is simple, and under high temperature and high speed, form ceramic layer and transition layer, and ceramic layer and transition layer form mechanical bond, transition layer and steel pipe matrix form metallurgy combination, and adhesive strength is better than viscose glue and combines.But because self-propagating reaction is comparatively fierce, in course of reaction, thermal losses is large, and the finite thickness that steel pipe inner wall is melted, causes the adhesive strength of metallurgy combination part limited, there will be the phenomenon that ceramic coating comes off under the operating mode of some HI high impact.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, the structure of the enhancing centrifugal self-propagating ceramic-lined composite steel tube intensity of favorable working performance and preparation method.
Technical solution of the present invention is:
Strengthen a structure for centrifugal self-propagating ceramic-lined composite steel tube intensity, it is characterized in that: comprise steel pipe, the internal surface of steel pipe offers groove, and the Al2O3 being lined with self-propagating reaction formation in the internal surface of steel pipe is ceramic-lined.
The groove that described steel pipe internal-surface is opened is the combination of single spiral chute or single rectangular groove or spiral chute and rectangular groove.
Described Al2O3 is ceramic-lined comprises ceramic layer and the transition layer between ceramic layer and the internal surface of steel pipe.
Strengthen a manufacture method for the structure of centrifugal self-propagating ceramic-lined composite steel tube intensity, it is characterized in that: comprise the following steps:
1. derusting by sandblasting, roughening treatment are carried out to steel pipe internal-surface, and slot at steel pipe internal-surface;
2. the self-propagating powder of Al+ Fe2O3 system is put into steel pipe;
3. be placed on centrifuge by steel pipe, start centrifuge, igniting causes self-propagating reaction, obtains product.
Single spiral chute is along steel pipe centerline direction, and rotation direction is left-handed or dextrorotation.
Single rectangular groove is distributed in steel pipe circumferentially, and groove number is 4-8.
The combination of spiral chute and rectangular groove: existing 4-8 is distributed in steel pipe rectangular groove circumferentially, and have again along steel pipe centerline direction, rotation direction is spiral chute that is left-handed or dextrorotation.
The present invention is rational in infrastructure, and the steel pipe internal-surface fluting of employing, makes the area of contact of ceramic coating and matrix increase, improve the anti-compression shear strength of conventional centrifugal self-propagating ceramic-lined composite steel tube ceramic coating; Ceramic coating part is goed deep in groove, makes composite pipe with ceramic lining have stronger shock resistance effect, effectively prevent the phenomenon that coating comes off from matrix.
