Description

A kind of device of removing iron scale

Technical field:

The invention belongs to metallurgy industry and produce the equipment that uses in the stainless steel process.

Background technology:

Produce in the stainless steel medium plate process at metallurgy industry, the finishing flow chart is arranged one.At present in the finishing flow chart, the cold rolling straightener of seven rollers is in the process of aligning corrosion resistant plate, a large amount of iron scale (iron scale) comes off from surface of steel plate, between lower support roller and its base, form and pile up, if untimely removing, plate surface quality, lower support roller and working roll are caused damage, and the product quality that causes producing reduces.Up to the present, remove iron scale and adopt artificial the removing and two kinds of methods of pressure-air removing, the work under bad environment of preceding a kind of method, staff's labour intensity is bigger, and the high-temperature operation environment has infringement to staff's health; A kind of method in back is that a large amount of iron scales is discharged in the atmosphere, and environmental pollution is more serious.

Summary of the invention:

The present invention aims to provide a kind of staff's of reduction labour intensity, and the device of the less removing iron scale of environmental pollution.

Realize that technical scheme of the present invention is: comprise housing and be installed in the power set on the housing, the device of scaling, power set connect the device of scaling by shaft coupling, power set connect reductor by motor by shaft coupling and constitute, power set are fixedly mounted on the bracing frame, bracing frame is fixedly mounted on the housing, and the device of scaling is made of sprocket wheel and the chain that is installed on the sprocket wheel, fixedly mounts Scaler on the chain, the device of scaling is fixedly mounted on the base, and base is fixedly mounted on the housing.

Operation principle of the present invention is: shown in Figure 15, the cold rolling straightener of seven rollers is in straightening steel plate, the iron scale 23 that comes off from the surface of steel plate is deposited between cold rolling straightener working roll 21 of seven rollers and the lower support roller 22, the chain of apparatus of the present invention 25 is along arrow direction, and iron scale 23 is along with the Scaler on the chain of apparatus of the present invention 25 is scavenged into underground.

By test at Shanxi Taigang Stainless Steel Co., Ltd's hot rolling mill; in the process of straightening steel plate, use the present invention to realize not shutting down on-line automatic removing to the iron scale that comes off from surface of steel plate; use the present invention to remove iron scale; reduced the number of times of changing lower support roller and working roll; prolonged one times of service life of lower support roller and working roll; saved roll changing time half a year 36 hours; 1800 tons of the steel plates of producing more; and reduced staff's labour intensity effectively; improve operating efficiency, improved product percent of pass.Do not use when of the present invention, change lower support roller and working roll, need the cost of overhaul, roller maintenance cost, scrap general expenses such as roller replacement cost and add up at least 30 ten thousand yuan every half a year, the present invention tests and had a surplus in ten months, ruuning situation is stable, and any fault does not take place the scale removal effect ideal.

The present invention has compact conformation, and is easy for installation, and scale removal effect is good, and is easy to maintenance, the characteristics of long service life.
