Abstract
The utility model relates to an automatic separating device for steelmaking casting slag steel, belonging to the technical field of iron and steel scrap processing and recovery. The automatic separating device comprises a stem, a circumferential partition, a radial partition and coating material. The stem (2), the circumferential partition (3) and the radial partition (4) are spliced and connected together through spot welding. The circumferential partition (3) and the radial partition (4) are provided with hoisting openings. The utility model has the advantages that the partitions can be recycled because the partitions are made of cast iron, cast steel or common carbon steel; no novel substance is added into steel slag and the separating device is protected against damages because the coating material on the surface of the device is made of steel slag; the steel slag processing difficulty is not increased because the composition of the steel slag is unchanged as a result that no other constituents are mixed into the device; the grade of solid slag steel processed by the device can reach more than 98 percent and the solid slag steel can be used as steel scrap and be directly returned back for steelmaking; and the occupied area of the device is small, the installation is convenient, the operation is reliable and the high-efficiency recovery and utilization of steel scrap resources are improved.
Description
Technical field
The utility model belongs to scrap iron and steel processing recovery technology field, and a kind of steel smelting casting residue steel automatic cutting device particularly is provided, and is applicable to that Ferrous Metallurgy casts the dividing processing of liquid molten steel in the surplus large-scale slag slag ladle.
Technical background
The steel-making ladle inclines in the slag process, has the remaining molten steel of part usually and together is introduced into specific slag ladle with slag, and layering cooling back forms bulk slag steel disc in slag ladle, radial dimension even can reach 3～4 meters, and weight can reach 4～5 tons.Use if will return steel-making, must cut apart it.Common processing mode is that hammer is pounded or gas is cut apart.It is low to use hammer to pound treatment effeciency, dangerous big, can produce very big noise and vibration, influences surrounding environment; The using gases dividing processing, energy resource consumption is big, and environmental pollution is very serious, part high-quality slag steel resource can be become slag simultaneously and run off.
Because prior art treatment effeciencies such as hammer is pounded, oxygen is cut apart are low, can store up a large amount of big slag steel (sticking together) in the slag field, so not only caused the waste of the plain resource of a large amount of high-quality iron, take a large amount of places simultaneously.Based on this situation, press for a kind of treatment technology of efficient, energy-saving and environmental protection, to solve the serious realistic problem that big slag steel (sticking together) is produced.
Utility model patent " metallurgical use slag ladle " (ZL01201699.3) preferably resolve because of deslagging produces a large amount of big slag steel (sticking together) can't be fast, the efficient problem of processing.This technology has improved the treatment effeciency of big slag steel (sticking together) to a certain extent, has reduced the processing cost of big slag steel (sticking together), and part has been improved the environmental problem in the processing procedure of big slag steel (sticking together).But this patent in use must be to slag ladle pad jar, and this mode can produce a large amount of dust in the slag process of inclining, and the secondary pollution problem is difficult to be solved at all.This device adopts cement to make as Binder Materials simultaneously, can only disposablely use.This device not only consumes this high energy consumption product of a large amount of cement, and has introduced new composition at slag, and the utmost point is unfavorable for the recycling in slag later stage.
Summary of the invention
The purpose of this utility model is to provide a kind of steel smelting casting residue steel automatic cutting device, is used for cutting apart the slag steel (liquid molten steel) in the large-scale slag slag ladle, and large-scale slag ladle is meant that volume is greater than 10m
3The slag ladle that holds liquid steel slag.
The utility model comprises stem stem, hoop dividing plate, dividing plate and smear material radially.By stem stem, hoop dividing plate, radially dividing plate is spliced, spot welding connects, and has lifting mouthful.
Be the center with the stem stem during splicing, installing ring has groove to dividing plate on the hoop dividing plate, is used to splice radially dividing plate.Stem stem, the hoop dividing plate and radially dividing plate all adopt cast iron or cast steel.Stem stem is the square column type.Diameter 10～15mm has groove all around, is used to connect radially dividing plate.Hoop dividing plate and block board thickness 10～20mm radially.To radially dividing plate, stem stem) and hoop dividing plate assembling combination is together, and use and smear applying material in baffle surface.Smearing material employing slag is that primary raw material is made, and the slag composition accounts for 95%.Form casting residue steel automatic cutting device like this.Slag ladle is subjected in the slag process, and liquid molten steel and slag are separated by casting residue steel automatic cutting device.Slowly cooling is easy to separate with slag behind the liquid steel water stratification, obtains high-grade slag steel; Do not need to cut apart separately, just can reach the dimensional requirement of converter steel scrap, return converter and use; So not only can save the processing cost of big slag steel (sticking together), also help and economize on resources, improve slag steel processing environment.This casting residue steel automatic cutting device all need adopt and smear applying material one time before using repeatedly, not damaged by high temperature with protective device.
The hoop dividing plate and radially dividing plate also can adopt solid metal material or box metal material to make. box metal material dividing plate inside stuffing be slag make smear material.
Device can be divided into 1～5 layer.
Advantage of the present utility model:
1, adopts metal material as isolated material, realize the recycling of isolated material, improve the life cycle of material, do not change the composition of slag simultaneously.The material of smearing of apparatus surface is made by slag, can additionally not increase novel substance and enter slag, can protect segmenting device to be without prejudice again.This device does not mix other components, can not cause the slag composition to change and causes the slag intractability to strengthen.Use the slag ladle of this device in being subjected to the slag process, splash or erosion can not occur.The solid slag steel grade that adopts this device to handle the back generation can reach more than 98%, can be used as steel scrap and directly returns the steel-making use.
2, adopt stem stem and radially, hoop dividing plate annular is spliced, and helps the use of large-scale slag ladle.
3, the dividing plate material is cast iron, cast steel or ordinary carbon steel.
4, dividing plate can adopt solid or box-type.
5, to smear material be the inorganic coating that slag is made to baffle surface, is not damaged with the protection dividing plate.
6, to take volume little, easy for installation, reliable for this device, the high efficiente callback and the utilization that can improve the steel scrap resource.
