3087 Low And Medium Pressure Boiler Steel Tube Hot Rolled/Cold Rolled

Product Intruction

The raw material of 3087 low and medium pressure boiler tube is round tube billet. The blank of round tube should be cut and processed by the cutting machine, and the length of the billet is about 1 meter, and sent to the furnace for heating by the conveyor belt. The billet is fed into the furnace and heated to a temperature of about 1200℃. The fuel is hydrogen or acetylene. Temperature control in the furnace is a critical issue. After the round tube billet comes out, it should be perforated by the pressure punch. Generally more common punch is the conical roller punch, this punch has high production efficiency, good product quality, large diameter expansion perforation, can wear a variety of steel. After perforation, the circular tube billet is successively three - roll oblique rolling, continuous rolling or extrusion. After extrusion, the diameter should be taken out of the pipe. The sizing machine rotates the steel embryo through the cone bit at high speed to punch holes and form steel tubes. The inner diameter of the steel pipe is determined by the outer diameter length of the bit of the sizing machine. Steel pipe after sizing, into the cooling tower, through water cooling, steel pipe after cooling, will be straightened. After straightening, the steel pipe is sent by the conveyor belt to the metal inspection machine (or hydrostatic test) for internal inspection. If there are cracks, bubbles and other problems inside the steel pipe, it will be detected. After quality inspection of steel pipes, they should be selected by hand strictly. After quality inspection of steel pipe, spray the serial number, specification, production batch number with paint. And hoisted into the warehouse by a crane.

Application

USED for manufacturing all kinds of low and medium pressure boiler, superheated steam tube, boiling water tube, water wall tube and superheated steam tube for locomotive boiler, large smoke pipe, small smoke pipe and arch brick pipe, etc. Hot - rolled or cold - rolled seamless steel tubes with high quality carbon structural steel. Mainly made of 10, 20 steel, in addition to ensure chemical composition and mechanical properties to do hydraulic test, rolling, flaring, flattening and other tests. Hot rolling is delivered in hot rolling state, cold rolling (dialing) is delivered in heat treatment state.
