Abstract
The invention relates to a preparation method for a slag steel partition plate. The adopted technical scheme is as follows: material proportioning is carried out according to parts by weight, 1 part of magnesite with granularity being less than 15mm, 0.05 parts to 0.3 part of cement, 0.1-0.5 part of river sand, 0.05-0.1 part of water; the allocated material is uniformly mixed and poured into different dies and pressed, wherein the dies are provided with splicing gaps; after health preserving, the demoulding is carried out; a demoulded plate is put into a furnace kiln and dried in the atmosphere of 100-300 DEG C; after being dried, each plate is connected by each spicing gap. The preparation method can dramatically reduce the processing cost of the slag steel, realize the effective reclamation of the slag steel, avoids the environment pollution, can manufacture partition plates with different shapes according to the shape of the slag slots in different steel mills and slag steel charging requirements. The preparation method fully uses waste slag steel in the steel mills and waste materials in magnesium production industries and saves the resource.
Description
Technical field
The present invention relates to and be used for the steel mill slag ladle, slag steel stone roller is divided into the some preparation method of cutting apart plate.
Background technology
At present, after the steel mill casting finishes, in ladle, there is surplus steel phenomenon to some extent, usually last molten steel and slag are poured in the slag ladle, solidify the back and form slag steel stone roller, this slag steel stone roller is because it contains a large amount of metals, has very high use value, but this kind slag steel stone roller is because its out-of-shape, volume can not directly enter smelting furnace greatly and smelt, normally adopt and manually cut or the method for the explosion of punching makes it be divided into the size that can go into stove with oxygen, this kind processing method need consume great amount of manpower, material resources, and relatively more dangerous in cutting and blasting process, the processing cost height, oxidation reaction in processing procedure can produce a large amount of smoke contaminations simultaneously, therefore, often form a large amount of slag steel stone rollers and suffer discarded situation, cause the wasting of resources.
In addition, the enterprise that produces magnesium also produces a large amount of magnesite discarded objects, causes the wasting of resources equally.
Summary of the invention
In order to address the above problem, the invention provides a kind of plate of cutting apart that raw materials such as magnesite make that adopts, slag ladle inside can be separated into several portions, make slag solidify back formation rule and the fritter that meets into stove smelting dimensional requirement, smelt directly into stove, not only made full use of discarded object, and reduced labour intensity, economize on resources.
To achieve these goals, the technical solution used in the present invention is: a kind of preparation method of slag steel partition plate, and step is as follows:
1) prepare burden by weight ratio, granularity is less than 1 part of the magnesite of 15mm, 0.05～0.3 part of cement, 0.1～0.5 part of river sand, 0.05～0.1 part in water;
2) mixing of materials for preparing is even, to pour in the different moulds of making according to the slag ladle shape, mould has the grafting gap, exerts pressure;
3) after the health, carry out the demoulding; Usually health is 8～24 hours;
4) plate after the demoulding is put into stove, under 100～300 ℃ of atmosphere, carry out drying; Usually dry 4～24 hours;
5) after the drying, every block of plate is pressed the gap socket connection.
The invention has the beneficial effects as follows: can significantly reduce the slag processing cost, realize the slag effective recycling.Adopt the plate of cutting apart of the present invention's preparation, the intensity height, place in the slag ladle, slag ladle can be separated into some fractions, steel mill pours last molten steel in the ladle in the slag ladle into like this, just is separated into plurality of small blocks after solidifying, can process again, directly just can go into stove and smelt again, cut down finished cost, realize the comprehensive utilization of resource.Owing to smelt again directly into stove, and need not adopt other modes to handle the slag steel, therefore avoided environmental pollution.The present invention preparation cut apart plate, easy for installation, Stability Analysis of Structures, sturdy and durable.Can make difformity and cut apart plate according to going into the stove requirement without steel mill's slag ladle shape and slag steel.Slag steel stone roller and the production magnesium enterprise discarded object discarded to steel mill make full use of, and economize on resources.

The specific embodiment
A kind of preparation method of slag steel partition plate, step is as follows:
1) prepare burden by weight ratio, granularity is less than 1 part of the magnesite of 15mm, 0.2 part of cement, 0.25 part of river sand, 0.08 part in water;
2) mixing of materials for preparing is even, to pour in the different moulds of making according to the slag ladle shape, mould has the grafting gap, exerts pressure;
3) demoulding is carried out in health after 15 hours;
4) plate after the demoulding is put into stove, under 200 ℃ of atmosphere, carried out drying 15 hours;
5) after the drying, every block of plate is pressed the gap socket connection together.
All be provided with gap on every block of plate of preparation, as shown in Figure 1, slag steel partition plate is made up of the following intermediate plate of a upper mid plate 1, one 2, two upper panel 3 and two downside panels 4 when using usually.
As Fig. 2～shown in Figure 5, every upper mid plate 1, be respectively equipped with socket 5, socket 6, socket 7 and socket 8 on intermediate plate 2, upper panel 3 and the downside panel 4 down.
During use, slag steel partition plate is placed in the slag ladle, slag ladle inside can be divided into 16 fractions, like this molten steel in the ladle and slag are poured in the slag ladle, after solidifying, slag steel stone roller is divided into 16 fritters, can be directly used in again and smelt.
