Abstract
The invention discloses stove whereabouts residues processing technique in a kind of converter steelmaking process, comprise the following steps: (1) when converter not blowing out, the first location scarfing cinder of remote control cinder bogie below converter and collection slag, described first location is in space for collecting ashes in a stove; (2) transport trolley near stove is outer second outside be set up reception slag, slag proceeds in the hopper of transport trolley by cinder bogie; (3) hopper is delivered to Slag treatment place by transport trolley, on Slag treatment the 3rd position, to fetch water immersion slag to hopper; (4) after cooling of furnace slag, slag is poured out by the deinstall that the inclines anti-hopper that inclines; (5) transport trolley is back to the second position, and hopper continues to come into operation.The present invention can realize converter not blowing out scarfing cinder operation, adopts environmental protection treatment, ensure that the normal production of steel-making, achieve the cleaning process of converter slag the bits cleaned out.
Description
Technical field
The invention belongs to field of steel metallurgy, relate to stove whereabouts residues processing technique in a kind of converter steelmaking process specifically.
Background technology
Converter is the visual plant in STEELMAKING PRODUCTION, at any time all can from fire door splash slag discharging in converter production process, also there are the bits spilt in converter deslagging process and fall into space for collecting ashes in a stove, and the effect of converter space for collecting ashes in a stove is collection falls slag, prevent converter accidents bleed-out, so space for collecting ashes in a stove normally uses down must ensure certain volume, if can not clear up in time, potential safety hazard certainly will be brought to converter producing, if when in space for collecting ashes in a stove, bits exceed orbit plane, can stop that ladle trolley and cinder ladle chassis are held less than under stove, even if under epistasis reaches stove, also keep away unavoidable, large clinker scrapes ladle nozzle slide plate off, after slide plate scrapes off, just open the tap hole of ladle, the molten steel putting into ladle spills from the mouth of a river, bleed-out accident can be caused.Bits under cleaning Converter, normally carry out in blowing out situation, the bits cleaned out are transported to Slag treatment, and in entrucking and toppling process, airborne dust is huge, are unfavorable for making steel environmental requirement.Part steel mill adopts the cleaning of remote control caterpillar shovel loader, but the effect used is not very desirable, and remote control caterpillar shovel loader not only oil consumption is huge, and operation of equipment is also very inconvenient.
Summary of the invention
The technical problem to be solved in the present invention is to provide stove whereabouts residues processing technique in a kind of converter steelmaking process, and this technique can realize converter continuous prodution, and cuts environmental protection and can reach steel-making requirements, overcomes the defect existed in prior art.
The present invention is by the following technical solutions:
Stove whereabouts residues processing technique in a kind of converter steelmaking process, comprises the following steps:
(1) when converter not blowing out, the first location scarfing cinder of remote control cinder bogie below converter and collection slag, described first location is in space for collecting ashes in a stove;
(2) transport trolley near stove is outer second outside be set up reception slag, slag proceeds in the hopper of transport trolley by cinder bogie;
(3) hopper is delivered to Slag treatment place by transport trolley, on Slag treatment the 3rd position, to fetch water immersion slag to hopper;
(4) after cooling of furnace slag, slag is poured out by the deinstall that the inclines anti-hopper that inclines;
(5) transport trolley is back to the second position, and hopper continues to come into operation.
Further, described transport trolley is fork truck.
Further, described fork truck is 3 ton forklifts, and the length of described hopper is respectively 1500mm, 900mm, 800mm.
Further, the described second position is the safety zone outside operator's space for collecting ashes in a stove that can work.
Further, in step (3), fetched water to hopper by spray header.
The present invention can realize converter not blowing out scarfing cinder operation, adopts environmental protection treatment, ensure that the normal production of steel-making, achieve the cleaning process of converter slag the bits cleaned out.

Embodiment
See Fig. 1, be the schema of stove whereabouts residues processing technique in the converter steelmaking process that the present invention relates to, comprise the following steps:
(1) when converter not blowing out, the first location scarfing cinder of remote control cinder bogie below converter and collection slag, described first location, in space for collecting ashes in a stove, is shown in Fig. 2;
(2) transport trolley near stove is outer second outside be set up reception slag, slag proceeds in the hopper of transport trolley by cinder bogie, sees Fig. 3;
(3) hopper is delivered to Slag treatment place by transport trolley, on Slag treatment the 3rd position, to fetch water immersion slag, see Fig. 4 to hopper;
(4) after cooling of furnace slag, slag is poured out by the deinstall that the inclines anti-hopper that inclines, and sees Fig. 5;
(5) transport trolley is back to the second position, and hopper continues to come into operation.
The small-sized clean slag car of remote control under stove, this cinder bogie vehicle body is less, can operation flexibly in narrow and small space for collecting ashes in a stove, has and pushes away slag, multi-functional such as dress slag, slag hitting etc.When converter smelting, operator stand in the operational safety district beyond space for collecting ashes in a stove, the slag union slag under remote control cinder bogie cleaning stove, and cinder bogie can be only movable in first location in space for collecting ashes in a stove.Deng collection after slag completes, the slag cleaned out in space for collecting ashes in a stove is loaded on the transport trolley beyond space for collecting ashes in a stove, in the second position of transport trolley near space for collecting ashes in a stove is outer, facilitate the transfer of slag, in the present embodiment, transport trolley is fork truck, this fork truck also comprises hopper, the length of hopper, wide, height is respectively 1500mm, 900mm, 800mm, hopper can be transported with 3 ton forklift forks, when hopper installs slag, fork truck can be carried to rapidly Slag treatment place, Slag treatment place is also the 3rd place, position, operator open spray header, fetch water in hopper, Deng cooling of furnace slag and after soaking into, just hopper is put into deinstall updip of inclining anti-, water-soaked slag, produce without any airborne dust, and operating efficiency height is very high, achieve the novel process of converter not blowing out scarfing cinder and converter slag environmental protection treatment.
