Description
Technical field
The present invention relates to a kind of first-born producing line of hot-strip and its production technologies, belong to metallurgy industry slag processing equipment skill
Art field.
Background technique
Hot-rolled strip steel toe is by purification, screening, heating and to be rolled by steel slag as raw material, is looked forward to mainly for steel
Industry steel-making uses.Currently, the first-born producing line of hot-strip be primarily present take up a large area, environmental pollution, slag iron separation effect are poor, at
The problems such as material rate is low, high production cost, is mainly manifested in the following aspects:
One, the purification of steel slag
Steel slag is a kind of slag iron solid waste to be mixed by iron, cement, soil, sundries etc..Under normal circumstances, steel mill can incite somebody to action
Wherein irregular size is sorted out in 700mm -800mm or more relatively big iron, is carried out physics and is beaten and directly return after cutting
With the iron block less than above-mentioned size then gives solid waste processing manufacturer progress slag iron separation purification processes.
The processing mode of slag iron solid waste mainly include the following types:
1, the solid waste of slag inclusion iron is transported to braised slag pool and is added by most domestic iron and steel enterprise and steel slag processing enterprise
Work makes slag iron generate separation, then carries out magnetic separation by certain time.Hot braised slag pool is carried out easily using expansion principle
Separating treatment keeps slag iron separating difficulty very big due to the complicated diversification of the shape and internal structure of steel slag, and iron cinder inclusion is this kind of just
It is more difficult separation, therefore, the Iron grade after being processed by this braised slag pool is not able to satisfy iron and steel enterprise less than 80%
The requirement of smelting.
2, using dry grinding, half mill, Vertical Mill, water mill, processing modes, but most of selection dry grinding processing such as roll, by hammering into shape
Beat, grinding after Iron grade between 72-80, then carry out water mill processing, after rinsing, grinding Iron grade between 80-90,
These processing technologys can be such that slag iron separates, but can not reach the ideal requirement of iron and steel enterprise's smelting.
There is also land occupation operation areas for the processing mode of two kinds of steel slags of above-mentioned steel slag greatly, to air pollution and water pollution etc.
Problem very serious.
3, using purification mechanical process, principle is to hammer into shape to strike slag iron solid waste by multiple roll more, is made
The separation of slag iron.Existing purifying machine has the disadvantage in that first is that hammer swing angle is small, small to the impact force of steel slag, slag iron
Inferior separating effect, Iron grade is low after separation；Second is that often blocking when processing is greater than 200mm and is less than the irregular material of 700mm
In the working chamber of equipment, equipment part is damaged；Third is that the replacement of hammer and the maintenance of purifying machine are inconvenient, it is time-consuming to take
Power.
Two, the heating of steel slag
It after slag iron separation, needs the steel slag after purification processes being heated to certain temperature, then by all kinds of slag irons of different shapes
Block is rolled into certain shapes, in order to store, transport and use for steelmaking process.
Traditional steel slag heating furnace generallys use tunnel oven or rotary kiln, and material is heated using tunnel oven, and material is heated
Unevenness influences the molding effect of steel slag；Material is heated using rotary kiln, and material is overturn with the rotation of roller, and passes through burning
Device torch firing into roller realizes the heating of material.This rotary kiln, material only lean on the rotation of roller and overturn, material overturning effect
Fruit is poor, and vibration equipment noise is big.
Three, the roll forming of steel slag
The molding milling train used on Vehicles Collected from Market is all traditional twin-roll machine, with roll shape shape blocker, then using cutting machine
Scale is completed, and slag iron then has very big difference with this tradition rolling raw material:
First, conventional mill has pan feeding shape and size certain requirement, is unable to complete undesirable material rolling.
And the shape and size of slag iron are multifarious, conventional mill is unable to complete this kind of material continuous rolling:
Second, conventional mill needs dedicated cutter or sawing machine to be cut off after by material roll forming, completes scale work
Make.And slag iron is formed is the multifarious tablet of size after rolling, so the common cutting machine also company of being unable to complete
Continuous cutting operation.
