Description
Technical field
Generally, the utility model relates to the heating system of hot-rolling of calender of a kind of fiber web machine.
Background technology
Press polish is usually used to the table of the smoothness and the glossiness that improve the fiber web of such as paper web and board web etc
Face attribute, and the bulk (caliber) of fiber web.According to calender position in fibrous-web manufacturing line and treat
The fiber web grade produced, press polish has difference in functionality.Such as, when producing the fiber web grade of coating, in coating
In final calender, fiber web is carried out press polish after front use precalender and coating.
Calender can be the merging part of fibrous-web manufacturing line or coating machine, i.e. calender on line.In calender shape
In the case of becoming separate unit, this calender is referred to as calender under line.Fiber web is by from coating machine or fiber web machine
Drying section is directed on line in calender.Fiber web is directed under line in calender from reeling end.
When press polish, web penetrates the nip (i.e. calendering nip) formed between roller against each other, in this nip, width
Material deforms due to the effect of temperature, humidity and nip pressure.
In calender, generally the different phase of this process will need the heat being fed in web pass by hot-rolling
Deliver in web.A kind of mode for transferring heat into hot-rolling is to arrange runner in hot-rolling housing, and heat transfer medium is along warm
Roller flows, and heat energy is delivered to the material of housing from heat transfer medium and is delivered to the web carrying out processing by there.Heat transfer medium
Can be gas or liquid or fluid media (medium), the most generally hot water, steam or oil.
Heat transfer medium can be sent to via the end pieces of hot-rolling be positioned at casing center or on casing peripheral
In runner.Generally, end pieces is believed to comprise flange section and the axle journal of roller, and end pieces is fastened in housing whereby, example
As fastened by bolt.
Various types of calender is used for the press polish of fiber web: logical in hard nip calender (machine calender)
Often have in 1-2 nip and the web nip between two hard rollers by press polish, soft press-polishing machine is generally of 1-4 nip
And at least one nip roll of nip is pressure release surface polymer roll.In hard nip calender and soft-nip calendering machine, Qi Zhongyi
Individual nip roll is heatable hot-rolling.Glazing calender is generally of 5-11 nip (i.e. 6-12 felt wrapped roll), and wherein 2-5 is individual
It is hot-rolling and 4-7 is pressure release surface, the roller of cover aggregation thing.
For calender, hot-rolling needs heating system, and it is generally arranged at the substrate of machine room of fibrous-web manufacturing line
In and with the stringing of the swivel joint leading to hot-rolling from heating system.Heating system also has for emptying and fill and using
In the container expanded.Expansion vessel has been positioned in machine room above calender.Therefore, when installing calender, heating system is also
Being mounted, this requires suitable workload and space.
Calender controls to be typically a part for the automatic system of fibrous-web manufacturing line, and it includes the heating system of hot-rolling
The temperature of system controls, and therefore has various chain effect between automatic system and temperature control.Generally, one from
Temperature controls in the Circuits System of automatic system, at least needs these chain effects: supply is flowed fluid temperature (F.T.), returned reflux fluid
Temperature, deposit temperature control unit quickly stop, controlling voltage unlatching, generic alert, pump operating cycle, stand-by pump operation, standby
In, filling/emptying pump operation preselected with pump, the preheating of fluid level minimum of a value, fluid level, substrate, fluid stream is ready, temperature
Setting value is preselected, heating is opened, cooling current are ready, emergent stopping, and in the control system from automatic system to temperature of hot-rolling
In one Circuits System of system, at least need these chain effects: computer heating control value, cooling controlling value, lay in, heat/cool down
Open, cooling water valve is opened, swivel joint is ready, machine emergent stopping.This make system extremely complex and need much for
The circuit of transmission information.
