Head Gupalo Vyacheslav Ivanovich, Registration Date 10-01-2005 Organization National Metallurgical Academy of Ukraine popup.description2 Object of the study- sectional furnace for heating pipes under termal processing. The hurpose of the work- increasing to capacity sectional furnace at heating of the pipes by diameter 530 mm for ensuring the velocities of the welding 20 m/h and reduction of the consumption of the natural gas on 10-15 % at heating of the pipes smaller diameter. On base experimental and the numerical studies of the heat work sectional furnace at system of the heating burner GNP designed modes of the heating of the pipes by diameter 159- 320 mm, providing spare fuel. The heating of the pipes by diameter 530 mm with thickness of the wall 10 mm at velocities of the displacement them along furnace 20 m/h can be realized with using jet-flame burners instead of burners GNP. It is shown that use jet-flame heating, under other army-on the conditions of, provides the reduction of the consumption fuel on 33 %, but using to screen insulation transporting roller reduces the loss of the heat with cooling water on 16 %. Removing of water from internal cavity of the pipes before sectional furnace provides the reduction of the consumption of the natural gas on 300 thousand m3/year more then.
