The application of a kind of heater element Elema 8 for melting and heat preservation stove provided by the invention:
One, the calculating of Elema 8 surface loading density
Elema 8 surface loading density refer to the electrical power that barred body heating position unit are can be born.The technology being provided by its manufacturer is thought: load density w and furnace wall 5 temperature Et and barred body surface temperature Et ＇ have following relation:
Under the identical condition of furnace wall 5 temperature, rod specific surface loading density large, rod service life just short, must guard against excess load use, Elema 8 surfaces that table 1 provides for producer are under specified serviceability temperature, the reference value of the maximized surface load density that different furnace temperature allow.
Table 1, Elema surface peak load density permissible value
Two, the selection of Elema 8 specifications
8 points of Four types of Elema, i.e. GC type, GD type, GDS type and GDC type, as the shaft furnace of deposite metal, we are normal, and what adopt is GC type and GD type, and especially ideal with GD type, facts have proved its 25%-35% that can economize on electricity.
Three, Elema 8 needs number to calculate
After the specification of Elema 8 is determined, the power that every Elema 8 can bear is:
Ｐ1＝F1w (w) （2）
P1 in formula---every power (w) that Elema 8 bears
F1---every Elema 8 heating part surface area (cm
2)
W---the load density (w/cm that under furnace temperature, heating part allows
2)
The number of the Elema 8 needing
The rated power (KW) of P in formula---stove
Four, the connected mode of Elema 8
The number of Elema 8 has adopted 3 multiple, and its connected mode has single-phase full series connection, single-phase full parallel connection and compound string parallel connection.Connected mode for three-phase has Y-connection method and triangulation method.(as shown in Figure 3, Figure 4) calculating formula of its power is:
U φ---phase voltage in formula, the resistance of every element of r
W1---star series connection power
W2---star power in parallel
Found out by (4) and (5) formula, the power of star parallel connection obviously increases.Use after a period of time, should change triangle into by star and connect.As shown in Figure 5 and Figure 6.The power meter formula of triangle series and parallel connection method is:
Ul in formula---line voltage, W3 triangulation method series connection power, W4 triangulation method power in parallel.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, but not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
