Abstract
The invention provides a device for continuously heating a steel strip by direct energization. The device comprises a tank body and at least one electrode assembly, wherein the electrode assembly is arranged in the tank body and corresponds to the steel strip; the electrode assembly comprises a main graphite roller and two small graphite rollers; the main graphite roller is arranged below the steel strip and connected with the steel strip; the two small graphite rollers are arranged above the steel strip and connected with the steel strip; and the steel strip is tightly compressed by the main graphite roller and the two small graphite rollers correspondingly. The device directly transmits currents to the steel strip for heating through the main graphite roller, and has the advantages of low energy loss and 95 percent of thermal efficiency.
Description
Technical field
The present invention relates to the thermal treatment field of steel band, be specifically related to the directly continuous heating unit of energising of a kind of steel band.
Background technology
When steel band is heat-treated, must heat steel band.Equipment to steel band heats continuously generally all adopts box-type furnace.Box-type furnace heats with resistance, the pyritous resistance wire heats muffle tube by thermal radiation, the pyritous muffle tube heats the steel band in the muffle tube by thermal radiation again, because heat passage complex forms, it is big to add this equipment cooling area, calorific loss is big, so the thermo-efficiency of box-type furnace is very low, generally has only 30%-45%.Also has a kind of thermo-efficiency induction heating preferably, it produces the very high alternating magnetic field of frequency by converter plant, utilize electromagnetic induction in steel band, to produce high-frequency vortex, thereby steel band is heated, and this heating unit will be used variable-frequency power sources, the equipment complexity, the lack of homogeneity of temperature, especially want its difficulty of the uniform ruhmkorff coil of design temperature very big, want the water flowing cooling, make its thermo-efficiency also have only 50-70% owing to will carry out the conversion and the coil of energy.
Summary of the invention
Technical problem to be solved by this invention is to provide the directly continuous heating unit of energising of a kind of steel band, and calorific loss is little, and thermo-efficiency is very high.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: a kind of steel band is the continuous heating unit of energising directly, comprise casing, be located at least one group electrode group corresponding in the casing with steel band, described electrode group comprises the main graphite roller that is located at steel band below and steel band and joins, be located at two little graphite rollers that steel band top and steel band join, described main graphite roller and two corresponding steel bands that compress of gravelstone ink roller.
As preferably, be provided with the brush that is connected with main graphite roller in the described casing, described brush is connected with the outside transformer that is provided with, and the secondary current of transformer is passed through the brush input electrode.
As preferably, described casing is provided with the steel band inlet corresponding with steel band, steel band outlet.
As preferably, described casing end is provided with temperature measurer.Be used for thermometric and temperature automatically controlled.
As preferably, described casing is provided with the nitrogen ventage.Feed nitrogen by the nitrogen ventage, the protection steel band is not oxidized.
As preferably, described electrode group adopts two groups.
Beneficial effect:
The present invention adopts technique scheme that the directly continuous heating unit of energising of a kind of steel band is provided, and calorific loss is very little, and thermo-efficiency can be up to 95%.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of steel band continuous heating unit of directly switching on, comprise casing 2, be located in the casing 2 at least one group electrode group corresponding with steel band 1, described electrode group comprises the main graphite roller 3 that is located at steel band 1 below and steel band 1 and joins, be located at two gravelstone ink rollers 4 that steel band 1 top and steel band 1 join, described main graphite roller 3 and two gravelstone ink rollers, the 4 corresponding steel bands 1 that compress.Be provided with the brush 5 that is connected with main graphite roller 3 in the described casing 2, described brush 5 is connected with the outside transformer 6 that is provided with.Described casing 2 is provided with the steel band inlet 7 corresponding with steel band 1, steel band outlet 8.Described casing 2 ends are provided with temperature measurer 9.Described casing 2 is provided with nitrogen ventage 10.Described electrode group adopts two groups.
Casing 2 usefulness steel plates are made, and feed nitrogen by nitrogen ventage 10, are used for protecting steel band not oxidized.Casing 2 inwalls have thermal insulation layer to be used for being incubated.It is the poor conductor of heat that casing 2 outer blocks have ceramic tile, ceramic tile, so it both can be incubated, makes casing 2 outward appearances beautiful again.The electrode group adopts the graphite welding roll, can make between steel band and electrode on the one hand not relatively move, thereby can not pull steel strip surface, and graphite can be high temperature resistant on the other hand, needn't use water cooling.Main graphite roller 3 is used for electric current is defeated by steel band 1, makes steel band 1 energising heat.Two gravelstone ink roller 4 no powers are used for compressing steel band 1, and steel band 1 can closely be contacted with main graphite roller 3, and two gravelstone ink rollers 4 can move up and down.Also not leaving before the casing 2 place after inherent steel band 1 heating of casing, one section uniform temperature zone, its effect are arranged is to make the temperature of steel band 1 can be evenly.Transformer 6 adopts the magnetic voltage regulator/transformer of low-voltage and high-current, add on the iron core of this kind transformer one group of magnetic control coil is arranged, the direct current energy that it feeds changes the magnetic flux of iron core, thereby change faradic size, change the size of transformer output voltage, the effect of this transformer unsteady flow is very good, and unsteady flow is also very convenient.Brush 5 links to each other with transformer 6 by copper bar, and electric current is imported main graphite roller 3.Temperature measurer 9 adopts infrared thermometer, and it can dynamically measure the temperature of steel band 1, and by automatic temperature control, realizes the automatic control of temperature of steel strips.
