Description

billet surface cleaning device

technical field

The utility model relates to a billet intermediate processing device, in particular to a billet surface cleaning device.

Background technique

The surface of the billet is prone to decarburization when it enters the heating furnace for heating. The anti-decarburization spraying technology of steel billets is still a relatively new field. The steel billets with a clean surface (with less iron oxide scale) are closely bonded with the anti-decarburization coatings and the billets. It is not easy to peel and burst when heated by a heating furnace, and it can better protect the surface of the billets. , to prevent surface decarburization. Generally, the oxide scale on the surface of the steel billet needs to be cleaned before spraying, otherwise the anti-decarburization coating will not be firmly attached to the surface of the steel billet.

At present, there are two main methods for cleaning the oxide skin on the surface of the billet. One is to use shot peening equipment to forcibly spray sand and metal pellets on the surface of the metal with compressed air. The method of oxide scale collision and friction can achieve the purpose of removing oxide scale. Another method is the method of direct cleaning with artificial wire brush. In the above two oxide scale cleaning methods, there are different degrees of limitations. First, the method of using shot blasting equipment to clean oxide scale has high investment in equipment, large space occupied by equipment, and large energy consumption by equipment. At the same time, sand and metal pellets are likely to cause environmental pollution during the spraying process. Although the method of using wire brushes and manual direct cleaning has the advantages of investors, due to the low cleaning efficiency, it is not suitable for large-scale mass production.

Utility model content

The technical problem to be solved by the utility model is to provide a steel billet surface cleaning device, which can effectively remove the scale on the steel billet surface, has a simple structure, reduces costs, and improves cleaning efficiency.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a steel billet surface cleaning device, including an underframe, a row of rollers arranged horizontally on the upper part of the underframe, a cleaning mechanism and a water mist mechanism, the cleaning mechanism It includes a first cleaning device and a second cleaning device with the same structure. The water mist mechanism, the second cleaning device and the first cleaning device are arranged in sequence along the moving direction of the billet. The four sets of nozzles, the axes of the four sets of nozzles are located in the same vertical plane.

The first cleaning device and the second cleaning device with the same structure both include roller brushes which are respectively arranged above and below the idler rollers by means of brackets and which rotate in opposite directions. The axis of the two sets of roller brushes is parallel to the axis of the idler roller. The first cleaning The roller brush installed below the idler roller and the roller brush installed above the idler roller by the second cleaning device rotate in the same direction.

The device also includes a drive motor, and the power output end of the drive motor is respectively connected to the idler roller, the first cleaning device and the power input end of the second cleaning device through a chain transmission mechanism.

It also includes a high-pressure water pump, and the water outlet of the high-pressure water pump is connected with the water inlets of four sets of nozzles.

The beneficial effects of adopting the above technical solution are: by using the existing rollers to transport the billet, the spray mechanism is used to spray the billet surface during the conveying process, and the spray formed on the billet surface absorbs the surface heat of the billet during the evaporation process, reducing the The temperature makes the oxide skin on the surface of the billet shrink and crack, which is easy to loosen and easy to clean. After spraying, the billet enters two sets of cleaning devices driven by the supporting rollers. The two sets of cleaning devices are respectively equipped with two sets of roller brushes and two sets of rollers. The rotation direction of the brush is opposite, and the two sets of cleaning devices are located on the same side of the billet. The rotation direction of the roller brush is also opposite. It can clean the surface of the billet from two different directions to ensure the cleaning effect. Compared with the shot blasting technology, the equipment structure is simple. No pollution to the environment, low cost and high efficiency.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

The anti-decarburization spraying technology of steel billets is still a relatively new field. Before spraying, the oxide scale on the surface of steel billets needs to be cleaned, otherwise the anti-decarburization coating will not be firmly attached to the surface of steel billets. The existing manual cleaning methods and shot blasting treatment There are different technical defects in the methods. Therefore, the utility model provides a billet surface cleaning device as shown in Fig. The mist mechanism 4, the cleaning mechanism includes the first cleaning device 1 and the second cleaning device 3 with the same structure, and the water mist mechanism 4, the second cleaning device 3 and the first cleaning device 1 are in a sequence along the direction of movement of the billet 2 Arranged, the water mist mechanism 4 includes four sets of nozzles respectively arranged around the supporting roller 6, and the axes of the four sets of nozzles are located in the same vertical plane.

The first cleaning device 1 and the second cleaning device 3 with the same structure all include roller brushes that are respectively arranged above and below the idler roller 6 by means of a bracket, and have opposite directions of rotation. The roller brush of the first cleaning device 1 located below the supporting roller 6 and the roller brush of the second cleaning device 3 located above the supporting roller 6 rotate in the same direction.

The device also includes a driving motor, and the power output end of the driving motor is respectively connected to the power input ends of the idler 6, the first cleaning device 1 and the second cleaning device 3 through a chain transmission mechanism, and also includes a high-pressure water pump, and the high-pressure water pumps out The water port is connected with four sets of nozzle water inlets.

The medium water and gas of the "water mist mechanism" of the present invention can come from high-pressure water and high-pressure gas in the workshop.

In a word, the utility model uses the existing supporting rollers to transport the steel billet, and first uses the spray mechanism to spray the steel billet surface during the conveying process. The spray formed on the steel billet surface absorbs the surface heat of the steel billet during the evaporation process and reduces the temperature. The oxide skin shrinks and breaks, and is easy to loosen, which is convenient for cleaning. The billet after spraying treatment enters two sets of cleaning devices driven by the supporting rollers. The two sets of cleaning devices are respectively equipped with two sets of roller brushes. The two sets of roller brushes rotate in opposite directions. The two sets of cleaning devices are located on the same side of the billet, and the roller brushes rotate in opposite directions, which can clean the billet surface from two different directions to ensure the cleaning effect. Compared with the shot blasting technology, the equipment has a simple structure, does not pollute the environment, and has low cost ,efficient.
