Abstract
A casting forming method includes the steps that melted iron is poured into an open ladle, and the open ladle is moved to a riser to be poured with melted iron. The casting forming method is characterized in that after the melted iron is poured into the open ladle, the open ladle in which the melted iron is poured is heated by adopting natural gas. By the adoption of the technical scheme, the open ladle is heated through the natural gas, in this way, it can be ensured that the melted iron in the open ladle is in a melted state instead of being solidified into iron scum, after the melted iron is poured into the riser, the high purity of a casting can be ensured, and the yield is increased.
Description
Technical field
The invention belongs to electrolytic aluminium field, specifically relate to a kind of foundry goods forming method.
Background technology
In aluminum electrolysis industry, need molten iron to pour in uncovered bag, more uncovered bag is moved on to rising head water molten iron.In the process of movement, the molten iron in uncovered bag is easily frozen into scum, if scum is poured in casting die with molten iron, can make shaping after foundry goods impure, reduce yield rate.
Summary of the invention
The object of this invention is to provide the foundry goods forming method that a kind of yield rate is high.
For achieving the above object, the present invention is by the following technical solutions:
A kind of foundry goods forming method, first pours into molten iron in uncovered bag, more uncovered bag is moved on to rising head place and carry out watering molten iron, after uncovered bag poured into by molten iron, heats the uncovered bag employing natural gas pouring molten iron into.Natural gas heating 10-20 minute is adopted to the uncovered bag pouring molten iron into.
Implement the uncovered bag heater that said method adopts, the tracheae that it comprises annular-heating portion and is connected with annular-heating portion, tracheae communicates with natural gas source of the gas; Described annular-heating portion is provided with ignition electrode and nozzle.
The bore of described nozzle is 5-10mm.
The bore of described nozzle is 8mm.
Described tracheae is provided with magnetic valve, and magnetic valve is connected with timer.
Described annular-heating portion is made up of at least two concentric endless tubes, and each concentric endless tube all communicates with tracheae.
Adopt the present invention of technique scheme, adopt natural gas to heat uncovered bag, can ensure that the molten iron in uncovered bag is molten condition like this, can not scum be frozen into, can ensure that foundry goods purity is high like this after pouring rising head into, thus improve yield rate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the uncovered bag heater of the present invention.
Detailed description of the invention
A kind of foundry goods forming method, first pours into molten iron in uncovered bag, more uncovered bag is moved on to rising head place and carry out watering molten iron.The present invention is for improving yield rate, and after uncovered bag poured into by molten iron, adopt natural gas to heat to the uncovered bag pouring molten iron into, 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, the tracheae 2 that it comprises annular-heating portion 1 and is connected with annular-heating portion 1, tracheae 2 communicates with natural gas source of the gas 3; Described annular-heating portion 1 is provided with ignition electrode 4 and nozzle 5.
The bore of nozzle 5 is 5-10mm, namely the bore of nozzle 5 be 5,6,8, arbitrary value in 10mm.
Tracheae 2 is provided with magnetic valve 6, and 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 is made up of at least two concentric endless tubes, and each concentric endless tube all communicates with tracheae 2.
Claims (7)
