Abstract
The utility model relates to a furnace for smelting by a perrin process. A mobile trolley and a mobile door are adopted to enable the furnace to be in a sealed system in smelting; the mobile door is arranged on one side of a reaction zone of the furnace, and the three other sides of the reaction zone of the furnace are sealed; an environmental fume collection port is arranged on a platform above a furnace roof; a fixed fume collection cover is connected with the platform; and a movable door is arranged on the fume collection cover and used for igniting. The mobile trolley is adopted to transport a sand nest and the furnace in/out of the reaction zone, and after the mobile door is closed, the reaction is conducted in the sealed space. The furnace has the advantages that the degree of automation is high, the operational flexibility is high, and the environment is protected. On one hand, the longer-time cooling process does not occupy the reaction position, so that the area of the reaction zone is reduced greatly, and the production operation flexibility is improved, and on the other hand, a large amount of fume emitted in violent reaction can be collected and processed well, so that the bad influence on the environment due to fume escape is reduced, the walk-off-loss of valuable metal is also reduced, and the recovery rate and the economic benefits of the metal are improved.
Description
Technical field
The utility model belongs to metallurgical processing and design field, relates to the configuration structure that a kind of molybdenum-iron perrin process is smelted.
Background technology
Molybdenum-iron is the iron alloy that molybdenum and iron form, and generally contains molybdenum 50～60%, as the alloy addition of steel-making.Molybdenum-iron is smelted the general perrin process that adopts.Stove is a cylinder that is placed on the sand base, the bricking of interior block clay, and the ferrosilicon with siliceous 75% and a small amount of aluminum shot are made reductive agent.After installing furnace charge, at the charge level initiator, such as nitre, aluminium bits or magnesium chips etc. is intense reaction after the igniting, then calmness, slagging, dismounting stove cylinder.The molybdenum-iron ingot cools off in the sand nest first, uses water quench again, carries out at last fragmentation, finishing.Configuration in the past adopts the mode of establishing the active set petticoat pipe above the molybdenum-iron stove to collect flue gas usually, all need to load and unload petticoat pipe before and after every secondary response, labour intensity is large, and stove is in an open system, smelt for the perrin process that violent, the instantaneous exhaust gas volumn of reaction is large, the flue gas collecting effect is poor, and the valuable metal walk-off-loss is large.
Summary of the invention
The purpose of this utility model provides a kind of perrin process smelting furnace, overcomes the shortcoming that in the past perrin process smelting reaction zone is large, the reaction flue gas can not be collected.
A kind of perrin process smelting furnace is characterized in that: adopt mobile trolley, portable door so that during melting stove be in the closed system.
A kind of perrin process smelting furnace is characterized in that: the stove reaction zone arranges the moving door except a side, and other three side seals close, and the furnace roof upper stage is reserved the set of circumstances mouth and is connected and fixed smoke collection cover, opens dodge gate on the smoke collection cover.Adopt mobile trolley sand transportation nest and stove turnover reaction zone, after portable door was closed, reaction occured in enclosed space.
The utility model structure has following advantage: level of automation is high, and flexibility of operation is large, and environment protection is good.On the one hand so that the process of cooling of long period does not take the reaction position, reduced widely the reaction zone area, and improved the production operation handiness, can collect well, process a large amount of flue gases that vigorous reaction is emitted on the other hand, alleviate flue gas and escaped the detrimentally affect that environment is caused, also reduce the walk-off-loss of valuable metal, improved metal recovery rate and economic benefit.

Embodiment
The below describes the embodiment of the utility model structure in detail:
Perrin process smelting furnace of the present utility model, adopt mobile trolley 1, portable door 2 so that during melting stove be in the closed system, the stove reaction zone is except a side arranges moving door 2, other three side seals close, the furnace roof upper stage is reserved the set of circumstances mouth and is connected and fixed smoke collection cover 3, opens dodge gate 4 on the smoke collection cover 3 and is used for igniting.
At first, the sand nest and the stove that are placed on the travelling car 1 are parked in outside the reaction zone, install material and enter reaction zone with travelling car afterwards, and the portable door 2 of reaction zone is closed, close the dodge gate 4 on the fixed set petticoat pipe 3 after the furnace roof upper stage igniting, reaction occurs in enclosed system.Melting reaction is very fast, emits simultaneously a large amount of flue gases, by the set of circumstances smoke pipeline with the flue gas collection and treatment.After finishing, reaction leaves standstill for some time, make slag and melt extraction, then bleed off slag, open portable door 2, the travelling car 1 that carries sand nest and stove rolls away from, sand nest splendid attire melt further cooling outside reaction zone, thereby vacates the reaction position, and other charged stoves can enter reaction zone and react.
This structure replaces the open reactive district with the confined reaction district, and level of automation is high, and environment protection is good, has improved metal recovery rate, is the inevitable choice of modern plant cleaner production; Outside reaction zone, cool off after reaction is finished, reduced the area of reaction zone and factory building, saved the project investment cost.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; make without departing from the concept of the premise utility some alternative or obvious modification that are equal to; and performance or purposes are identical, then should be considered as belonging to the protection domain that claims that the utility model submits to are determined.
Claims (2)
1. perrin process smelting furnace is characterized in that: adopt mobile trolley (1), portable door (2) so that during melting stove be in the closed system.
2. perrin process smelting furnace according to claim 1, it is characterized in that: the stove reaction zone is except a side arranges moving door (2), other three side seals close, and the furnace roof upper stage is reserved the set of circumstances mouth and is connected and fixed smoke collection cover (3), opens dodge gate (4) on the smoke collection cover (3).
