Abstract
The invention belongs to the technical field of medium-frequency induction heating furnaces and in particular relates to a stowing tool and a process for emptying the medium-frequency induction heating furnace by applying the same. The shape of the stowing tool in the invention is identical with that of blanks entering the medium-frequency induction heating furnace. The stowing tool is made from a non-conducting and non-magnetic refractory material. When the medium-frequency heating furnace is to complete working, the stowing tools are arranged on the rear side of the last stage of blanks sequentially along the moving direction of the blanks until the last stage of blanks finish heating. When entering an induction coil of the medium-frequency induction heating furnace, the stowing tool of the invention does not emit heat, so that the stowing tool not only does not consume electrical energy, but also does not influence the blanks which need to be heated. With gradual increase of the stowing tools in the furnace and gradual decrease of the blanks which need to be heated, a medium-frequency current of the medium-frequency induction heating furnace is automatically attenuated and the power is also decreased therewith until the last stage of blanks is discharged. The stowing tool and the process for emptying the medium-frequency induction heating furnace by applying the stowing tool have the advantages of simple structure, low production cost, practicability and reliability.

Medium Frequency Induction Heating Furnace is because volume is little, in light weight, easy for installation, the efficiency of heating surface is high and to being heated advantages such as the workpiece scaling loss is little, meet the requirement of energy-saving and environmental protection and sustainable development, has obtained extensive use in industrial production.But existing Medium Frequency Induction Heating Furnace body of heater is than length and do not have the suitable equipment that empties or device, in order the final stage blank to be released burner hearth during end-of-job at every batch of product or every day, usually can only adopt constantly to fill in burner hearth does not need the metal stock that heats, comes out of the stove until the blank that final stage need heat.Because metal stock itself has the characteristic of conduction, magnetic conduction, make these finally also reach the same temperature of blank with the needs heating in order to empty metal stock that burner hearth just adds afterwards, this process for emptying has not only caused waste of electric energy, improve production cost, and influenced the thermal effect of adding of the blank that needs heating; Simultaneously above-mentionedly be used to empty the metal stock of burner hearth, its metallographic structure is damaged, also just reduced the quality of product if also need post bake when utilizing once more.
Summary of the invention
The purpose of this invention is to provide a kind of pusher, it is simple in structure, and cost is low and practical reliable.
For achieving the above object, the present invention has adopted following technical scheme: a kind of pusher, and the shape of described pusher matches with the shape that enters the blank of Medium Frequency Induction Heating Furnace, and pusher is made by non-conductive also non-magnetic refractory material.
The invention provides a kind of Medium Frequency Induction Heating Furnace process for emptying of pusher of application of aforementioned accordingly, its technical scheme is: when the intermediate frequency induction heater will power cut-off, described pusher is added in the rear side of final stage blank successively along the moving direction of blank, finishes until the final stage blank heating.
From the above, pusher among the present invention is made by non-conductive also non-magnetic refractory material, therefore pusher enters interior self heating of induction coil of Medium Frequency Induction Heating Furnace, so pusher i.e. consumed power not, do not influence the blank that needs heating yet, continuous increase along with pusher in the stove, need the continuous minimizing of heating blank, the electric current of intermediate frequency of Medium Frequency Induction Heating Furnace will be decayed automatically, power also descends thereupon, after to the last one section blank was come out of the stove, electric current of intermediate frequency and power just dropped to sky stove value, so just reached the purpose of using electricity wisely.To get the present invention simple in structure by above-mentioned, and production cost is low and practical reliable.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the body of heater 30 of existing Medium Frequency Induction Heating Furnace is longer, generally have about 2.4M, the heating-up temperature of Medium Frequency Induction Heating Furnace is generally 1200 ℃ simultaneously, therefore traditional Medium Frequency Induction Heating Furnace is in order to heat required final stage blank 21 and release body of heater 30, usually need to add the long metal stock of 2.4M, and the long metal stock of this section 2.4M also is heated to 1200 ℃, thereby caused greatly waste.
The shape of the pusher 10 among the present invention matches with the shape that enters the blank 20 of Medium Frequency Induction Heating Furnace, and pusher 10 is made by non-conductive also non-magnetic refractory material.
As preferred version of the present invention, described pusher 10 is that the magnesia of binding agent is made by zirconia ceramics or with the sodium metasilicate.
From the above, the pusher 10 usefulness heavy refractory materials of the furnace charge process for emptying special use of this Medium Frequency Induction Heating Furnace are made by the model knotting, have intensity height, not squashy characteristics, so long service life; Simultaneously owing to self do not generate heat in the induction coil that refractory material is non-conductive, not magnetic conduction, so pusher 10 enters Medium Frequency Induction Heating Furnace 40 that pusher 10 is adopted, thus promptly not consumed power do not influence the blank that needs heating yet.
As shown in Figure 1, the direction of the arrow indication shown in the figure is the moving direction of blank 20, when the intermediate frequency induction heater will power cut-off, described pusher 10 is added in successively the rear side of final stage blank 21 along the moving direction of blank 20, continuous increase along with pusher in the stove 10, need the blank 20 of heating constantly to reduce, the electric current of intermediate frequency of Medium Frequency Induction Heating Furnace will be decayed automatically, power also descends thereupon, after one section blank, 21 heating to the last finish and come out of the stove, the electric current of intermediate frequency of Medium Frequency Induction Heating Furnace and power just drop to sky stove value, have so just reached the purpose of using electricity wisely.
Simultaneously if adopt the conventional metals blank to empty body of heater 30, because the metal stock temperature of staying at last in the burner hearth is very high, needs at least 20 minutes or longer time just can be closed recirculated cooling water, even adopt the aid of iron staff and so on that the high-temperature metal blank in the body of heater 30 is taken out, also can be not easy to operate or deposit, also increase personnel labor and uneasy congruent factor simultaneously because temperature is high.And when adopting process for emptying of the present invention, after being full of pusher 10 in the body of heater 30 of induction furnace,, therefore can close the recirculated cooling water of Medium Frequency Induction Heating Furnace immediately because pusher 10 can not be heated, improve production efficiency greatly, also greatly reduced production cost simultaneously.
For example: with a blank that can heat diameter 100mm, body of heater length is that the induction furnace of 2.4M is an example, empties a burner hearth about 150Kg of blank that need pack into, heating power consumption is pressed 0.5KWh/Kg and is calculated, each prepurging 75KWh that can economize on electricity, with prepurging secondary calculating every day, the every month 3750KWh that can economize on electricity.
The present invention has changed traditional furnace charge process for emptying, has not only reduced power consumption, has also alleviated personnel labor simultaneously, has filled up domestic of the same trade blank.
