Description of the Equipment
1.1 Brief introduction
The furnace includes loading table, heating section, quenching and
cooling section, unloading table, and control system. It is used to
manufacture flat glass for window,door furniture, home appliance,
architecture glass, etc.
1.2 Loading Table
The loading table is composed of rubber-covered rollers and Kevlar
rope. When the glass is put onto the rollers, the glass will be
conveyed automatically to the entrance of the furnace where it will
be in ready-to-enter-furnace position and the rollers stop moving.
It will send the glass into the furnace once the computer control
system gives enter command.
1.3 Heating Section
The structure of the heating section is of a double-layer box type
covered with thermos-insulation material. Inside the section there
is a conveyor system with high temperature resistant ceramic
rollers. Heating elements and radiation plates are installed on the
upper layer and lower layer of this section. The upper layer
radiation plate is special heat resistant and anti-corrosion cast
material. The heating element is of an integrated part with spiral
type resistance erected on ceramic part, it's easy to replace. When
the glass is going to enter the furnace, the front door of the
heating section opens the rolls of the loading table and heating
section move at the same time. When the glass is in the furnace,
the front door will close and the glass on the rollers will be
moved back and forth at the distance calculated by the controlling
system automatically, so that the glass will be heated evenly. The
upper section can be lifted up for maintenance. The heating
elements are in matrix layout.
1.4 Flat Quenching/Cooling Section
The alloy sections and steel sheet is cold riveted to avoid
deformation of heat welding, ensure effectively the entire flatness
at air face of quench. Rational nozzle aperture and arrangement of
air hole guarantee the glass even cooling. The upper and lower
quenches are combined with linkage and individual drives, which can
actually control the rational height for air nozzle of quenches.
Matched with balance control of upper and lower air amount, the top
and bottom of the glasses can reach to optimum heat radiation, so
as to ensure the flatness of tempering glass.
1.5 Forced convection heating system
Balance tube made by air tube of convection heating system with
leptospira model. The convection air comes from compressor to spray
hot air into the surface of the soft coat Low-E glass; under the
production working process, the heating chamber is combed with both
forced convection and radiation. In any case when you expect to
process Low glass(both soft and hard coat), you could switch on the
compressor control and when you only intend to process clear float
glass you can only adopt radiation for processing.
1.6 Unloading Table
The unloading table is the similar as the loading table. When the
glass is transported to the end of the conveyor, the rollers will
stop, and the glass can be taken away by hand, or by robot, if
there is available at the customer's factory.
1.7 Control System
The control system includes the followings:
Process parameters storage and recall, such as glass thickness,
size, color, glass type and maybe different sources of float glass
and etc.
Whenever you produce a new order for different thickness, size,
color, type, source and etc., you just enter the process
parameters, and the system will memorize these process data. Nest
time, when you have the re-order, or the same order, you can
re-call the data, and the machine will automatically use the stored
processing data to produce.
Controller for roller driving system.
Controller for the temperature control.
Controller for quenching control.
The furnace has auto pre-heating function.
After the shift of a day, the furnace will be in the stand-by
status; only less than 25% of heating power will be consumed, while
the ceramic rollers will be still running.
And ahead of working time on the next morning, the system will
start up to heat up to the working temperature until the operator
begins the production.
The main industrial control computer is installed with the
terminals at the control desk. Display screen can provide users
with analog process Status: main screen, process parameter screen,
operation and maintenance screen and system parameter screen.
The system has reading and writing function for process parameters,
automatic control, unit equipment operation and test as well as
self-diagnosis, as well as display alarming function.
Main drive control system is accomplished by the inverter system,
which is controlled by computer. Online of every part is controlled
by computer.
The main screen is the page displayed on the monitor during normal
production. The contents displayed directly in English are the
statuses of glass in the furnace, driving system, temperature at
each zone, time of heating, quench and cooling, set point of fans
and length sum of pieces of glass in the furnace. This screen is
for the operator's notice.
The process parameter screen records when the pedal switch is
actuated by the operator, temperature set point of upper and lower
furnace, pressure set point of fans, quench time and cooling time
set point. These screens are frequently used for normal operation.
Maintenance
screen is used by maintenance people to test every part of the
system. System parameter screen is used by the manufacturer, in
order to test the machine, it is not for any other people using,
and otherwise the machine may be damaged. The system also has some
supplementary screens,
which will not be explained here.
