Abstract
The invention discloses a process for making an arched and welded alumina-ceramics wear-resistant elbow and an elbow. The process is characterized in that: an elbowed shell is made first, then an alumina ceramic block matched with the shape of the shell is prepared, and the ceramic block is stuck on the inner wall of an elbowed tube by adhesive, the ceramic block is closely combined with a steel tube. The elbow is characterized in providing an elbow shell which is stuck with the alumina ceramic block by adhesive. The process has the advantages that the hardness is high, the high-temperature oxidation resistance is excellent, the sticking is close, the strength of combination of the ceramic block and the steel tube is high and the ceramic block still does not fall off, and the life-span is long; moreover, the manufacture technology can save a large amount of metal materials, greatly reduce the weight of the wear-resistant elbow, facilitate the installation and maintenance and save the manufacture cost of a pipe frame.
Description
Technical field
The present invention relates to electric power, metallurgy, cement, iron and steel technology, is the bend part of a kind of wear-resistant bend manufacturing technology and made, specifically, is a kind of arch form structure alumina ceramic wear resistant elbow making process and elbow.
Background technique
For a long time, in industries such as electric power, metallurgy, cement, iron and steel, carry to contain in the pipeline of granule materials, particularly elbow very easily weares and teares, and for solving this difficult problem, once uses rare earth alloy and abrasion resistant cast steel etc. to make and produces, and operation all can not reach desired life.
Summary of the invention
The purpose of this invention is to provide a kind of hardness height, high temperature oxidation resistance is good, paste closely knit, porcelain piece and steel pipe adhesive strength height, working life with overlength, save a large amount of metallic material, alleviate the weight of wear-resistant bend greatly, make things convenient for I﹠M, also saved arch form structure, welding type alumina ceramic wear resistant elbow making process and the elbow of pipe support fabricating cost.
Technical solution of the present invention is:
A kind of arch form structure, welding type alumina ceramic wear resistant elbow making process, it is characterized in that: make the elbow shell earlier, be ready to the aluminium oxide ceramics piece with the shell complementary shaped again, stick with glue agent then ceramic block is sticked on the elbow internal wall, its ceramic block and steel pipe are combined closely.
Adhesive described in the present invention adopts polymer ceramic plastic powder stick.When sticking on ceramic block on the elbow internal wall, affix to last piece, will post the porcelain piece with wooden mallet and suffer piece and knock, its ceramic block and steel pipe are combined closely, and piece and piece reach seamless effect, measure the width dimensions of last piece, and widen 1-2mm, knock in wooden mallet then and put in place.The ceramic block longitudinal joint of two adjacent rings is staggered.
A kind of elbow of making of arch form structure, welding type alumina ceramic wear resistant elbow making process is characterized in that: the elbow shell is arranged, stick with glue agent on the elbow shell and be pasted with the aluminium oxide ceramics piece.
Shell described in the present invention adopts plate making among the thick Q235 of 5-10mm.The thickness 10-25mm of ceramic block, it is curved to resolve into dried shrimp by the radius of curvature of elbow shell, and every joint bent angle is not more than 15 °.Ceramic block cuts into the shape that matches with bent angle.
Beneficial effect of the present invention is: the hardness height, high temperature oxidation resistance is good, paste closely knit, porcelain piece and steel pipe adhesive strength height, therefore, even wear-resistant bend is subjected to external impacts, ceramic block still can not drop, thereby has the working life of overlength.In the conveying that generally contains granule materials, when lined ceramics thickness is 12.5mm, but safe operation 8-10, when thickness is 25.4mm, but safe operation 18-25.Because arch form structure has increased elbow intensity, compares with other materials, making can be saved a large amount of metallic material, and the proportion of aluminium oxide ceramics is 3.6g/cm3, also alleviate the weight of wear-resistant bend greatly, made things convenient for I﹠M, also saved the pipe support fabricating cost.
Description of drawings
Accompanying drawing is a kind of structural representation of using the elbow of arch form structure alumina ceramic wear resistant elbow making process making of the present invention.
Embodiment
Accompanying drawing has been described a kind of elbow of making of arch form structure, welding type alumina ceramic wear resistant elbow making process of the present invention.Elbow shell 1 is arranged, stick with glue agent on the elbow shell 1 and be pasted with aluminium oxide ceramics piece 2.Described shell 1 adopts plate making among the thick Q235 of 5-10mm.The thickness 10-25mm of ceramic block 2, it is curved to resolve into dried shrimp by the radius of curvature of elbow shell 1, and every joint bent angle is not more than 15 °.Ceramic block 2 cuts into the shape that matches with bent angle.
Making method of the present invention is:
Make the elbow shell earlier, be ready to the aluminium oxide ceramics piece with the shell complementary shaped again, stick with glue agent then ceramic block is sticked on the elbow internal wall, its ceramic block and steel pipe are combined closely.Described adhesive adopts polymer ceramic plastic powder stick.When sticking on ceramic block on the elbow internal wall, affix to last piece, will post the porcelain piece with wooden mallet and suffer piece and knock, its ceramic block and steel pipe are combined closely, and piece and piece reach seamless effect, measure the width dimensions of last piece, and widen 1-2mm, knock in wooden mallet then and put in place.The ceramic block longitudinal joint of two adjacent rings is staggered.
The present invention from tension principle, designs the elbow of different bores according to arch form structure, adopts the aluminium oxide ceramics porcelain piece of difformity, varying number.After porcelain piece liner is installed, make 360 ° the interior porcelain interblock of a circle produce bigger self-supporting power mutually, so more can effectively increase the service life.Because arch form structure, paste closely knit, porcelain piece and steel pipe adhesive strength height, therefore, even wear-resistant bend is subjected to external impacts, ceramic block still can not drop.
