Abstract
The utility model discloses an open-ladle heating device which comprises an annular heating part and a gas pipe communicated with the annular heating part. The gas pipe is communicated with a natural gas source, and ignition needles and nozzles are arranged on the annular heating part. According to the open-ladle heating device in the technical scheme, an open ladle is heated through natural gas so that it can be guaranteed that molten iron in the open ladle is in a molten state and free of being solidified to form iron scum, it can be guaranteed that the purity of a casting is high after the molten iron is poured into a riser, and therefore the finished product rate is improved.
Description
Technical field
The utility model belongs to electrolytic aluminium field, specifically relates to a kind of foundry goods forming method.
Background technology
In aluminum electrolysis industry, molten iron need to be poured in uncovered bag, more uncovered bag is moved on to rising head water molten iron.In mobile process, the molten iron in uncovered bag is easily frozen into scum, if scum is poured in casting die with molten iron, can make the foundry goods after moulding impure, has reduced yield rate.
Utility model content
The purpose of this utility model is to provide the foundry goods forming method that a kind of yield rate is high.
For achieving the above object, the utility model is by the following technical solutions:
A uncovered bag heater, it comprises annular-heating portion and the tracheae being connected with annular-heating portion, tracheae communicates with natural gas source of the gas; In described annular-heating portion, be provided with ignition electrode and nozzle.
The bore of described nozzle is 5-10mm.
The bore of described nozzle is 8mm.
On described tracheae, be provided with magnetic valve, magnetic valve is connected with timer.
Described annular-heating portion consists of at least two concentric endless tubes, and each concentric endless tube all communicates with tracheae.
Adopt the utility model of technique scheme, adopt natural gas to heat uncovered bag, can guarantee that like this molten iron in uncovered bag is molten condition, can not be frozen into scum, after pouring rising head into, can guarantee that like this foundry goods purity is high, thereby improve yield rate.
The specific embodiment
Fig. 1 is the structural representation of the uncovered bag heater of the utility model.
The specific embodiment
A foundry goods forming method, first pours molten iron in uncovered bag into, more uncovered bag is moved on to rising head place waters molten iron.The utility model, for improving yield rate, after molten iron is poured uncovered bag into, adopts natural gas to heat to pouring the uncovered bag of molten iron into, and the heat time is 10-20 minute, is the arbitrary value in 10,12,15,18,20 minutes.
As shown in Figure 1, a kind of uncovered bag heater, it comprises annular-heating portion 1 and the tracheae 2 being connected with annular-heating portion 1, tracheae 2 communicates with natural gas source of the gas 3; In described annular-heating portion 1, be provided with ignition electrode 4 and nozzle 5.
The bore of nozzle 5 is 5-10mm, the bore of nozzle 5 be 5,6,8, the arbitrary value in 10mm.
On tracheae 2, be provided with magnetic valve 6, magnetic valve 6 is connected with timer 7.Like this, after heating certain hour section, uncovered bag heater can quit work automatically.
Annular-heating portion 1 consists of at least two concentric endless tubes, and each concentric endless tube all communicates with tracheae 2.
