The specific embodiment

Contrast accompanying drawing below; Through description to embodiment; To effect and operation principle, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc.; Do further detailed explanation, inventive concept, the technical scheme of the utility model are had more complete, accurate and deep understanding to help those skilled in the art.

The structure of the utility model of expressing like Fig. 1 to Fig. 7 is a kind of continuous casting billet descaling device, is arranged on the strand rollgang 9 before continuous casting billet 4 gets into heating furnaces.The mechanical descaling device that the utility model provides comprises working method, forms mechanism, mounting means.

In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realization minimizing steel rolling is gone into the stove casting billet surface and is adhered to iron scale, the goal of the invention of energy-conserving and environment-protective, and the technical scheme that the utility model is taked is:

To shown in Figure 7, the continuous casting billet descaling device 10 that the utility model provided comprises framework 2 like Fig. 1, and described framework 2 is installed in two strand conveying roller 1 position intermediate of two roller-ways on the described strand rollgang 9, and the crossbeam welding of furnace roller road is fixing with going into; Described framework 2 is established steel wire rope fixed block 3, on described steel wire rope fixed block 3, establishes many fixing steel wire ropes 5, and the end of described steel wire rope 5 is pressed on the surface of described continuous casting billet 4.

Be to satisfy energy-saving and cost-reducing requirement, the iron scale of taking mechanical system to remove casting billet surface is the most direct one of effective method.

Steel wire rope 5 passes steel wire rope fixed block 3, and in the gathering sill of continuous casting billet 4 processes, the head steel wire of steel wire rope 5 scatters, and plays the effect of wire brush, and steel wire rope 5 deep length are adjusted according to continuous casting billet 4 specifications voluntarily.When continuous casting billet 4 from descaling device 10 processes the time, the steel cord end of steel wire rope 5 is wiped the iron scale of surface attachment off to the surface scrape of continuous casting billet 4, does not stay cut at casting billet surface again, and plays scale removal effect.

As depicted in figs. 1 and 2, on described framework 2, establish gas purging pipe 12, and be communicated with source of the gas through gas piping.

The front end of framework 2 can be installed a gas purging pipe 12, utilizes the gas with certain pressure, and the iron scale of removing is blown off.

As shown in Figure 1, oxide skin collection tray 11 is established in the below of described descaling device.

The oxide skin collection tray 11 that sheet metal is welded is placed in the below, collects the iron scale that descaling device 10 is removed, and periodic cleaning.

To shown in Figure 5, perpendicular to the through hole on described continuous casting billet 4 surfaces, described steel wire rope 5 passes described through hole, and through tight fixed bolt 6 described steel wire rope 5 is fastened on the described steel wire rope fixed block 3 on the described steel wire rope fixed block 3 like Fig. 1.

Steel wire rope 5 is connected firmly through tight fixed bolt 6 and steel wire rope fixed block 3, and the length that steel wire rope 5 exposes can be done suitable adjustment according to continuous casting billet 4 sections.Continuous casting billet 4 is through the driving of strand conveying roller 1, and through descaling device 10, the steel wire that the head of steel wire rope 5 scatters forms wire brush, to the surface scrape of continuous casting billet 4, the iron scale that adheres on the surface is removed.

The installation of steel wire rope 5 and adjustment can freely be adjusted according to continuous casting billet 4 specifications sections.

Through friction after a while, steel wire rope 5 wearing and tearing can be unclamped tight fixed bolt 6, and the extension elongation of steel wire rope 5 is done suitably adjustment, insert fixed block, and locking tight fixed bolt 6 continues to use again., so repeatedly, until steel wire rope 5 too short can't uses.The steel wire rope 5 that this mechanism uses is junks that shop traveller changes, and reduces use cost.

The fixed form of steel wire rope fixed block 3, like Fig. 3, Fig. 4 and shown in Figure 5, described steel wire rope fixed block 3 is through set bolt 7, set bolt 8 fastening being installed on the described framework 2.

As shown in Figure 5, described steel wire rope 5 is pressed on the upper surface and two sides of described continuous casting billet 4.And its bottom surface because of with strand conveying roller 1, can automatically oxide skin be removed.

Strand rollgang 9 is accomplished de-scaling in the process of carrying strand, do not need additional process.Simultaneously, the simple adjustment mode of steel wire rope 5 and simple structure make this covering device be simple and easy to use; Effectively reduce the quantity that gets into heating furnace casting billet surface iron scale; Improve the heating furnace efficiency of heating surface, played good reduction gas consumption, the effect that reduces cost.

Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the method design of the utility model and the improvement of the various unsubstantialities that technical scheme is carried out; Or the design of the utility model and technical scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
