Walking Beam Billet 250t/H Rolling Mill Continuous Heating
Large-Tonnage
Steel material in the furnace by the step beam up and down the reciprocating movement, there is a certain interval between the steel material, steel material can be heated in all directions, high thermal efficiency, short heating time, less scale of oxide, decarbonization possibility is small, no stick steel, steel surface will not produce scratches, is conducive to eliminating black marks, improve the heating quality.
Manufacturing process of walking beam furnace
The front part of the feeding roller table → weighing → measuring length → positioning of the feeding roller table → opening of the feeding furnace door → hydraulic steel pusher → measuring the billet width → positioning on the billet walking beam → the mechanical equipment (including hydraulic system) of the heating furnace move according to the process design. The billet is heated in the furnace according to the heating process requirements → the billet is positioned through the laser detection point → the steel signal is required → the discharge furnace door rises → the steel is taken by the steel holder → the billet is positioned on the discharge roller → the furnace door is closed → descaling and rolling.

Compared with the pusher-type heating furnace, its advantages are: flexible material transport, when necessary, the furnace charge can be all discharged; the blank is spread out at intervals at the bottom of the furnace or on the beam, which can be heated evenly faster. The fault of arch steel and sticking steel of pusher-type heating furnace is completely eliminated, so that the length of furnace is not restricted by these factors.
Features:
1. Steel can be heated from all sides, high thermal efficiency, short heating time, less oxidized sheet, less possibility of decarburization, will not produce sticky steel, steel surface will not produce scratches, is conducive to the elimination of black marks, improve the heating quality.
2. Low energy consumption, flexible operation.
Be adaptable. It is suitable for heating a variety of steel materials such as ingot, billet, slab, round billet, etc. The requirements on the length, thickness and other aspects of steel materials are not strict.
