30t/H Capacity Walking Beam Type Reheating Furnace For Steel
Product
Reheating furnace process description
Seamless steel tubes are sent to the reheating furnace according to
the predetermined production plan, and the basic data of the steel
tubes are input into the computer system of the reheating furnace,
and the computer controls and tracks the furnace process.
After the length of the steel tube to be fed into the furnace is
measured on the charging roller table outside the furnace (or the
length of a batch of materials is manually input), and it is
confirmed that there is no material on the charging roller table
inside the furnace, the furnace door is opened, the charging roller
table outside the furnace and inside the furnace rotates at the
same time, and the steel tube is fed into the furnace. The speed
and running time of the roller table in the furnace are controlled
by the photocell, so that the steel tube into the furnace is
accurately positioned on the roller table, and then the furnace
door is closed.
The steel pipe positioned on the charging roller is transferred
from the charging end to the discharging end by the reciprocating
periodic movement of the movable beam. When the steel pipe is sent
to the discharge roller, it has been heated to the set temperature
according to the predetermined process system. At this time, the
discharging furnace door opens, the discharging roller rotates, the
steel pipe is transported out into the next process, and the
furnace door is closed.
The above process in normal production is by PLC sequence, chain,
automatic control, also has semi-automatic and manual functions.
The loading and discharging end is equipped with industrial TV to
monitor the loading and discharging area in the furnace.
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.
