Abstract
본 발명은 각종 유체 또는 분말 수송관, 배관이나 화학반응용관으로 사용되는 복합관의 제조방법에 관한 것으로서, 그 목적은 내부표면에 치밀한 세라믹층이 형성될 수 있는 복합관의 제조방법을 제공함에 있다.The present invention relates to a method for producing a composite tube for use in various fluid or powder transport tubes, pipes or chemical reaction tubes, and an object thereof is to provide a method for manufacturing a composite tube in which a dense ceramic layer can be formed on an inner surface thereof.
본 발명은 회전몰드(1)의 내측에 금속관(2)을 삽입하고, 상기 금속관(2)의 내부에 테르밋(thermit) 반응용 혼합 분말을 장입한 후 상기 급속관(2)을 회전시키면서 상기 혼합분말의 점화로 일어나는 테르밋 반응열을 이용하여 금속관(2)의 내부에 세라믹층을 형성시킴을 포함하는 복합관(10)의 제조방법에 있어서, 상기 테르밋 반응직후에 금속관(2)의 내부에 형성되는 세라믹 생성물층(4)의 표면을 강제 냉각시키는 테르밋 반응을 이용한 복합관의 제조방법에 관한 것을 그 기술적 요지로 한다.The present invention is inserted into the metal tube (2) inside the rotary mold (1), the mixture of thermite (thermit) reaction powder into the inside of the metal tube (2), and then the mixing while rotating the rapid tube (2) In the method of manufacturing a composite tube 10 comprising forming a ceramic layer inside the metal tube 2 by using thermite reaction heat generated by the ignition of the powder, the ceramic formed inside the metal tube 2 immediately after the thermite reaction The technical gist of the present invention relates to a method for producing a composite tube using a thermite reaction for forcibly cooling the surface of the product layer 4.
