Description

Smelting ingot casting treatment system and online treatment method thereof

Technical Field

The invention relates to a smelting ingot casting treatment system and an online treatment method thereof.

Background

In metal regeneration, the process of smelting, pouring and casting ingots and related devices thereof have critical influence on the quality, yield, production efficiency and product quality of ingot products. The existing production process and device for smelting and casting ingot by using regenerated metal. Firstly, for a smelting system, the furnace group setting cannot be reasonable, the setting quantity and mutual positions of all smelting furnaces, the mutual matching of the furnaces with different functional properties and the like are difficult to be reasonable in setting, and the influence and restriction on the metal regeneration in different degrees are generated. For example, the smelting and component preparation of the smelting furnace have a role of mutual conversion, the set number of the furnaces is too large, the output, the utilization rate and the waste of energy and resources of each furnace are influenced, the equipment investment is increased, the relative production efficiency is reduced, and if the set number of the smelting furnaces is too small, contradictions and influences caused by the smelting, the component preparation, the production scale and the like can occur.

Secondly, the casting system, the existing casting device and the casting mode thereof have great irrationality, the pouring device (liquid injection) and the casting mold line have unreasonable structures, the casting liquid is injected in a single way along with the continuous operation of the casting mold line, the coordination problem that the pouring cannot continuously supply liquid and is wasted exists, and meanwhile, the discharging and staying time of the casting liquid is too long, so that the production efficiency is influenced, the heat loss is large, and the ingot casting quality is also influenced.

Thirdly, the existing smelting furnace group is difficult to be arranged reasonably and optimally, and one of the most key factors is the influence and restriction problems caused by the coordination of the pouring launders on the number of the furnace groups, the function conversion distribution of the furnaces and the like and the interconnection of the pouring launders and the casting mould lines. That is, because the height of the outlet of the molten metal in each furnace of the furnace group is fixed, the arrangement positions of the furnaces with various functions must ensure that the pouring chutes of each furnace are connected with the casting module line, and each pouring chute is fixedly connected with each furnace and the casting module line, therefore, the arrangement of the furnace group must consider the mutual positions of the furnaces, the position of the casting module line, the related facilities on the peripheral ground of the furnaces, the necessary connecting pipelines of each furnace, etc., the facilities are criss-cross, different in height and complicated, so that the arrangement of the pouring chutes cannot be carried out according to a reasonable and layout way, meanwhile, the pouring chutes of each furnace converge into the casting module line, because the arrangement and the protection limits are limited, the arrangement and production scale of the furnaces are restricted, the unreasonable arrangement number of the furnace group is produced, and the furnaces cannot effectively exchange the functions and use roles, if the components are prepared, the preparation can not be completed by furnaces in different positions and different working conditions according to requirements.

Fourthly, as for the casting refining treatment mode and the corresponding device, the opening is firstly arranged on the furnace top, a stirrer is arranged on the furnace top, when the refining treatment is needed, the furnace is firstly stopped, the operation of the smelting system is stopped, the top furnace mouth cover is opened, the stirrer is arranged from the top furnace mouth, the smelting liquid in the smelting furnace is stirred, and the refining agent is inserted and added from the top furnace mouth while stirring. On one hand, the stirrer is arranged on the top of the furnace, so that the space is limited, the range of motion is small, the safety problem is obvious, on the other hand, due to the fact that hot gas is extremely large during refining treatment, the impact on equipment is large, the operation is extremely difficult and even cannot be endured, and the method mainly aims at setting a site through particularly building a smelting furnace and is rarely used at present. The existing common mode is a treatment mode of adding a refining agent into a furnace door, wherein during treatment, the furnace door is opened, a machine drives a stirring rake to stir, and the refining agent is added from a furnace opening. The method also needs to shut down the furnace and stop the system, the heat loss is extremely large, the shutdown of the smelting system causes production loss, the continuity of the operation condition of the system is influenced, great loss is caused to the production, the operation is also troublesome, the difficulty is high, and the stirring is discontinuous and uniform. On the other hand, the existing stirrer adopts a stainless steel stirrer, and is easy to deform, damage and short in service life. Of course, there are also devices arranged at the bottom of the furnace, but the structure is more complicated, and the operation is more inconvenient and difficult.
