The position of second baffle 322 is changed, is fed by the second tremie pipe 32 for the second batch can 521 in the second hot sending system 52, second
Tremie pipe 32 is that the first batch can 511 is transported to going out for pre-reducing furnace 1 by the first waggon 512 during the second batch can 521 feeds
Material mouth 11, prepare splicing.High temperature pelletizing 13 after prereduction is put into the first batch can 511 from the discharging opening 11 of pre-reducing furnace 1, is gone out
When doses reaches the weight specified, stop splicing, and switch the position of first baffle 122, be second by the first tremie pipe 12
The second batch can 521 in hot sending system 52 feeds.
Before corresponding batch can is delivered to mineral hot furnace 2 by waggon, corresponding batch can is first transported to auxiliary material Cang4Chu additions and referred to
Determine the auxiliary material 43 of weight.Specifically, the auxiliary material 43 of specified wt can be first added into the first batch can 511, then switches the 3rd
The position of baffle plate 422, it is that the second batch can 521 feeds by the 3rd tremie pipe 42.Then by the first lifting device 514 by the first material
Tank 511 is promoted to mineral hot furnace 2, and the material in the first batch can 511 is poured into mineral hot furnace 2, after adding material into mineral hot furnace 2, by
First batch can 511 is positioned on the first waggon 512 by the first lifting device 514, and the first waggon 512 is in the first transmission track
The first batch can 511 return reduction feed bin 3 is carried on 513 to feed, and repeats said process.
According to other compositions of the system 100 of the production ferrochrome of the utility model embodiment and operate for ability
All it is known for the those of ordinary skill of domain, is not detailed herein.
The side that a kind of system 100 of the production ferrochrome using in above-described embodiment produces ferrochrome is described below
Method.The method of production ferrochrome comprises the following steps：
The pelletizing 13 processed is sent into pre-reducing furnace 1 and carries out prereduction；
Batch can is transported at reduction feed bin 3, the reducing agent 33 of certain mass is added by reducing feed bin 3 into batch can；
Batch can is transported at pre-reducing furnace 1, after adding the prereduction of certain mass into batch can by pre-reducing furnace 1
Pelletizing 13；
Batch can is transported at mineral hot furnace 2, batch can is transported to by batch can by the charge door of mineral hot furnace 2 by lifting device
Interior material pours into mineral hot furnace 2.
Thus, it is possible to which the high temperature pelletizing 13 after prereduction is delivered into mineral hot furnace 2 by hot sending system, it is sufficiently used
The waste heat of pelletizing 13 after prereduction, so as to which material to be rapidly heated to more than 1300 DEG C of high temperature in mineral hot furnace 2, show
Reduce energy consumption of the pelletizing 13 when mineral hot furnace 2 is smelted with writing, accelerate the progress reduced deeply.Meanwhile batch can receives prereduction
Before high temperature pelletizing 13 afterwards, reducing agent 33 is first received, reducing agent 33 and air exclusion can be made, avoid reducing agent 33 from aoxidizing
Reaction, reduces the loss of reducing agent 33.
According to some further embodiments of the present utility model, batch can is transported at pre-reducing furnace 1, receives pre-reducing furnace
It is further comprising the steps of after pelletizing 13 in 1 after prereduction：Batch can is transported to auxiliary material Cang4Chu, by auxiliary material storehouse 4 into batch can
Add the auxiliary material 43 of certain mass.Thus, it is possible to auxiliary material 43 is covered on the high temperature pelletizing 13 after prereduction, on the one hand can profit
Carried out heating auxiliary material 43 with the waste heat of pelletizing 13, on the other hand air can be completely cut off by auxiliary material 43, reduce pelletizing 13 and connect with air
Tactile chance, the generation for avoiding secondary oxidation from reacting.
