Description

Energy-efficient cutting slag cleaning rifle

Technical field

This utility model relates to a kind of cutting slag cleaning plant, a kind of energy-efficient cutting slag cleaning rifle.

Background technology

Currently, the slag tumor (being commonly called as dross, also referred to as burr) that steel mill's continuous casting line strand flame cutting is formed, always steel making working procedure ratio Problem relatively difficult to tackle, is because: these casting blank section bottoms and the slag tumor of corner, both sides, directly affects subsequent processing-steel rolling.If these melt Slag nodule is not cleared up before strand enters steel rolling process, on the one hand can directly cause strand feed mill difficulty, have a strong impact on rolling mill practice and rolling efficiency. On the other hand the roll that the slag tumor of casting blank section is run up when entering milling train pulverizes, and a large portion is ground in stocking, at stocking table Face forms a lot of rough oxidation cinder hole.Because roll continues rolling after through, until finished product, stocking is that thickness is the most thinning, area progressively becomes Greatly, so being equal to be progressively to be exaggerated by defect ware area.The large area that slight slag tumor causes milling material is defective, has had a strong impact on and has rolled Quality of item and rolling lumber recovery.

To this end, all steel mills all can not stint input, adopt all necessary measures and " burr " that method to allow people be vexed this is removed.

The two ways is currently mainly taked to remove the slag tumor (being commonly called as dross, also referred to as burr) of casting blank section corner to be: artificial to carve Son, flat chisel or by directly beaing removal with hammer.This be the most original be also that maximally effective a kind of burr removing method (can be accomplished not at all Let slip).But, labor cleaning gets up that labor intensity is big, tool wear fast (slag tumor and strand degree of fusion is good, fusion intensity high), service cycle It is long that (, all between several tons to tens tons, after the temperature of deburring strand to be waited until lowers, overhead traveling crane to be utilized is by the casting of stacking for every block casting base Base scatters, and just can carry out labor cleaning's burr work, also want stack after having cleared up), human and material resources, financial resources, equipment investment are big, dangerous system Number height, work efficiency is extremely low.Two are: utilize special equipment flash trimmer to remove.Due to this body structure of flash trimmer and own characteristic thereof, cause The application of flash trimmer is by following circumscribed restriction.(1) the equipment initial stage puts into big, energy consumption height: at present, flash trimmer substantially price is the people About 700,000 yuan of coin, cost of equipment is high, the initial stage puts into big；Additionally flash trimmer complete machine match power is at about 70 kilowatts, and power consumption is high, the most greatly Power consumption can deserve to be called a no small spending for the slim profit that continuous-cast blank produces.(2) floor space is big, production line length is long: Flash trimmer equipment start so that continuous casting line overall length increases substantially, the thing followed is that Factory Building span wants big, and Factory Building and auxiliary facility initial stage throw Enter big.(3) flash trimmer floor space is big, determines that flash trimmer can be only applied to single current or two and flows parallel sheet slab, and occupies bigger market part The continuous casting lines such as the parallel small billet of the compact multithread of volume, rectangular bloom, little slab cannot use at all.(4) flash trimmer self structure and work Skill feature determines that the round steel billet burr that another round billet continuous casting machine occupying the bigger market share is produced by it is willing and yet unable to help (because circle base dross is one The individual arc surface at perpendicular) (5) flash trimmer tool wear is fast, maintenance workload is big, operating cost is high: flash trimmer is to pass through high-speed rotary The fly cutter rotary-cut turned or a lot of circular arc cutting knife rely on forward and reverse movement of semifinished product " to scrape " to fall, due to burr i.e. slag tumor and strand degree of fusion is good, Fusion intensity is high, causes tool wear block, and maintenance workload is big, and operating cost is high.On the other hand, continuous casting is casting continuously, a cast week In phase, strand is continuously toward going out, even if finding tool wear, deburring effect dying, is also not do the enough time to shut down replacing, Can only by with！By the time after this cast terminates, then replacing is shut down, so personnel at the scene have same common recognition: go when just having changed cutter The deburring effect of burring machine is exactly good, but good times don't last long, and abrasion occurs in cutter one, and deburring effect is had a greatly reduced quality immediately.

In view of As-Is, we, in line with the Innovation principle of " high-quality, efficient, energy-saving and environmental protection ", have developed: energy-efficient cutting is melted Slag cleaning rifle.
