Abstract
The invention relates to a production method of a slag ladle partition plate for processing casting residue steel, which belongs to the technical field of processing and recycling of waste steel. Steel slag, refractory materials, cement and steel bars are used as raw materials; the steel slag and the refractory material are loaded into a distributing bucket of a batching machine respectively, and then are weighed by a belt and then poured into a stirring tank of a stirring machine by a raw material bucket of the stirring machine, and the cement is conveyed by a screw conveyor and is weighed and further enters the stirring tank of the stirring machine. A receiving hopper is used for conveying partition plate raw materials into a pouring machine. The pouring machine is used for pouring the raw materials into a mold, and after trowelling, the mold is conveyed to the lower end of a palletizing machine by a steam curing machine. The palletizing machine is used for stacking the mold on a steam curing trolley and then pushing the mold into a curing kiln for curing. After completing the curing, the partition plate is pushed out from the other end of a kiln body, the mold is disassembled, the palletizing machine is used for clamping the partition plate and stacking the partition plate on the steam curing trolley, and then the partition plate is conveyed to a finished product yard for stacking and natural curing. The production method has the advantages of being simple and practical in process flow.
Description
Technical field
The invention belongs to iron and steel scrap processing recovery technology field, particularly relate to a kind of residual casting slag steel and handle the production method of using the slag ladle dividing plate.
Technical background
After steel-making continuous casting is finished, have the remaining molten steel of part in the ladle usually and together be introduced into specific slag ladle with slag, 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 it.Common processing mode is that hammer is pounded or the gas cutting.It is low to use hammer to pound processing efficiency, dangerous big, can produce very big noise and vibration, influences surrounding environment; The using gas cutting process, energy 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 processing efficiencies such as hammer is pounded, oxygen machining 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 " (ZL 01201699.3) 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 processing efficiency 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 treating processes 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 gelling material 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.
Utility model patent " a kind of steel smelting casting residue steel automatic cutting device " (CN 201455257U) 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 the hoop dividing plate, radially dividing plate all has lifting mouthful.Advantage is that dividing plate adopts cast iron, cast steel or plain carbon stool to make, and can repeatedly recycle; The material of smearing of apparatus surface is made by slag, can additionally not increase novel substance and enter slag, can protect cutting 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.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; It is little that this device takies volume, easy for installation, reliable, can improve the high efficiente callback and the utilization of steel scrap resource.But this patent does not provide concrete Production Flow Chart, and metallic substance is easy to generate distortion in slag sticks together tilting procedure simultaneously, and the complete-reclaiming difficulty is bigger.
Utility model patent " the smooth windmill shape of slag Ge type separates bulkhead bracket " (CN 2011265015Y), utility model patent " slag stone roller reticular pattern spacer plate " (CN 201154960Y) and utility model patent " a kind of slag steel partition plate " (CN201381327Y) all are described slag steel cutting device, but do not have to disclose the concrete grammar that it is manufactured.
Summary of the invention
The object of the present invention is to provide a kind of residual casting slag steel to handle the production method of using the slag ladle dividing plate, make technical process simple, practical.
The present invention is a raw material with slag, refractory materials, cement and reinforcing bar, also can adopt aggregate to substitute slag.According to weight percent, slag accounts for 50～65% in the raw material, and refractory materials accounts for 20～35%, cement accounts for 10～20%, and reinforcing bar accounts for 3～5%; The production system of this production method is made up of batching stirring system, formation system and kiln body.Batching stirring system equipment comprises that proportioning machine, belt claim and stirrer.Formation system comprises casting molding machine, the steam-cured dolly composition of setting machine.Concrete grammar is respectively charged into slag and refractory materials in the batch hopper of proportioning machine for adopting forklift, after the belt weighing, pour in the stirred pot of stirrer by the former hopper of stirrer, cement adopts worm conveyor to carry, and after weighing, enters in the stirred pot of stirrer and stirs.Add water stir finish after, by hopper clapboard raw material is transported in the casting molding machine.Casting molding machine is poured into raw material in the middle of the mould, floating after, mould is transported to the setting machine lower end by steam-cured dolly.Setting machine is stacked mould, pushes health in the health kiln then.Dividing plate after health is finished is released from the kiln body the other end, takes mould apart, with setting machine dividing plate is picked up to be deposited on the steam-cured dolly, is transported to the finished product stockyard then and piles up natural Health preservation.It is stand-by that vacant steam-cured dolly adopts travelling platform to be transported to place on the track of kiln external body.Dividing plate that health is good and dividing plate adopt the electric welding mode to weld together, and form a whole set of dividing plate, use for the steel smelting casting residue jar.
Advantage of the present invention:
1, is raw material with slag, refractory materials, cement and reinforcing bar, also can adopts aggregate to substitute slag.
2, simple, practical, the realization easily of technical process.The equipment of selecting for use in the technical process all is that common equipment is produced in present concrete production and building block
3, adopt the slag ladle spraying material to be sprayed on baffle surface, slag and dividing plate are not sticked together.
