Abstract
The utility model relates to a kind of channel structure of frequency cored induction furnace.The channel structure of this frequency cored induction furnace comprises the induction ware be arranged in burner hearth, and wherein induction ware departs from burner hearth center and is asymmestry section structure with the annular channel that inboard wall of burner hearth is formed.The utility model has the features such as the life-span is long, the thermal efficiency is high, reduction scaling loss.
Description
Technical field
The utility model relates to a kind of line frequency furnace, especially a kind of channel structure of frequency cored induction furnace.
Background technology
In non-ferrous metals processing field, particularly copper and alloy melting process thereof, core line frequency furnace is had to apply quite universal.And have the channel structure of core line frequency furnace directly to affect life and the production efficiency of electric furnace.What major part smeltery of current China used has core line frequency furnace to be all uiform section annular channel, but a kind of like this channel structure of form has a fatal shortcoming, and the molten metal exactly bottom channel is almost " dead band " of not circulating.High temperature due to electromagnetic action and molten metal washes away and causes various refractory oxide to enter in this part " dead band ", causes the quartz sand of channel wall to come off through washing away, and cause accumulated slag too much, channel part and the burner hearth temperature difference comparatively greatly, cause channel to rupture.
Summary of the invention
The purpose of this utility model is to provide that a kind of life-span is long, the thermal efficiency is high, reduces the channel structure of the frequency cored induction furnace of scaling loss.
The utility model is solved by following technical proposal: the channel structure of this frequency cored induction furnace comprises the induction ware be arranged in burner hearth, and wherein induction ware departs from burner hearth center and is asymmestry section structure with the annular channel that inboard wall of burner hearth is formed.
The utility model adopts asymmestry section channel structure to make molten metal in channel, form directed high-speed motion, slag in melt enters molten thorax with the flow at high speed of molten metal, slag body accumulates hardly in channel, decrease the temperature difference of molten metal inside and outside channel simultaneously, accelerate the circulation of molten metal, improve the thermal efficiency, reduce scaling loss.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment asymmestry section channel structural representation.
Detailed description of the invention
As shown in the figure, this embodiment comprises the induction ware 1 be arranged in burner hearth, wherein respond to ware 1 and depart from burner hearth center, induction ware 1 outer wall and inboard wall of burner hearth is made to form the annular channel 2 of asymmestry section structure, induction ware 1 center is from radial distance R3, R2 of inboard wall of burner hearth difference, and R3>R2>R1(R1 is the radius of induction ware 1).
What this embodiment melted the employing of copper electric induction furnace is unequal section ring-type one-way flow channel, and metal liquid makes one-way flow in channel, overcomes the shortcoming that uiform section channel produces high temperature " dead zone ", enhances heat exchanging process in stove.
Claims (1)
