Description

Technical Field

[0001] The utility model belongs to the technical field of steel billet processing, in particular to a high-efficiency dephosphorization device for steel billet production. Background Art

[0002] Alloy steel billets are mainly composed of elements such as iron, chromium, and carbon, with the chromium content usually being 10.5% or above and the carbon content being 1.2% or below. They have various properties, such as good corrosion resistance and the ability to resist erosion by chemicals such as air, water, acid, and alkali. The billet dephosphorization device is an important equipment specifically used to remove phosphorus from the surface of the billet. This device usually uses high-pressure water jet technology to use the powerful impact force of the water flow to remove impurities such as oxide scale and phosphide from the surface of the billet. Its working principle is to generate high-pressure water flow through a high-pressure pump and spray it onto the surface of the billet through a nozzle. Under the action of the impact force, impurities are peeled off from the surface of the billet.

[0003] Existing technologies include a utility model with publication number CN220479751U, which discloses a billet descaling device. The patent adopts a high-pressure gas source and a nozzle, wherein the high-pressure gas source is connected to the nozzle, and the nozzle is used to descaling the billet. The high-pressure gas source is a heating furnace drum, and the water vapor continuously discharged from the heating furnace drum is used for descaling the billet; by introducing the water vapor continuously discharged from the heating furnace drum into the above-mentioned nozzle for descaling the billet, energy waste is reduced, and the production cost of the hot rolling process is further reduced; at the same time, water vapor descaling directly removes iron oxide scale into the turbid circulating water entering the ditch, and no longer enters the rolling mill, reducing the particulate matter content in the air of the rolling mill, thereby saving dust removal costs, achieving the purpose of energy saving and environmental protection, and solving the problem that the operating cost of high-pressure water descaling is generally 0.5-1 yuan per ton of steel, and the investment in high-pressure water preparation equipment is large.

[0004] In the process of cleaning the steel billet with the help of a dephosphorization device, there is an existing steel billet dephosphorization device such as the above-mentioned one, which cleans the oxidizing medium on the surface of the steel billet with a single high-pressure water vapor. Since there is a threshold value for the pressure of the high-pressure water vapor, when the oxidizing medium attached to the surface of the steel billet is relatively stubborn, it is difficult for the high-pressure water vapor to peel off the oxidizing medium, so that the steel billet needs to be processed twice. Repeated processing of the steel billet will cause the efficiency of the equipment to be disturbed, thereby leading to a problem of reduced processing efficiency of the equipment for the steel billet. Utility Model Content

[0005] Aiming at the problem that the current process of removing phosphorus from steel billets using high-pressure water guns cannot remove impurities with strong adhesion, the utility model provides a high-efficiency phosphorus removal device for steel billet production, which effectively improves the effect of phosphorus removal on the surface of the steel billet.

[0006] The utility model is realized through the following technical solutions:

[0007] A high-efficiency dephosphorization device for stainless steel billet production includes a base, a conveying rack arranged on the upper part of the base, a processing chamber arranged on the upper part of the conveying rack, and an auxiliary component arranged inside the processing chamber;

[0008] The conveyor frame is provided with a plurality of conveyor rollers arranged side by side, the conveyor rollers are driven by belts, and the main conveyor roller is connected to the output end of the first motor arranged on the side of the conveyor frame;

[0009] The processing chamber is an "I"-shaped structure, with two openings connected along the axial direction of the conveyor frame, and both sides are fixedly arranged on the side of the conveyor frame; a rectangular guide hole is provided in the middle of the top of the processing chamber for placing auxiliary components;

[0010] The auxiliary components include a support frame, a hydraulic cylinder, a connecting rod, a load-bearing frame and a cleaning frame; the top of the support frame is provided with a hydraulic cylinder, and the bottom is fixedly arranged on the top of the processing chamber; the protruding end of the hydraulic cylinder passes through the interior of the support frame and is connected to the connecting rod; the interior of the connecting rod is hollow and provided with a bidirectional screw rod, one end of the bidirectional screw rod is connected to the output end of the servo motor, and the other end is connected to the bearing; the servo motor is arranged at one end of the connecting rod, and the bearing is arranged at the other end of the connecting rod; the bidirectional screw rod body is provided with threads in opposite directions, and is respectively threadedly connected to the load-bearing frame, a cleaning frame is fixedly provided at the bottom of the load-bearing frame, and a scraper is provided on the inner side of the cleaning frame;

[0011] The connecting rod is horizontally arranged and located just above the guide hole in the same direction as the guide hole; the load-bearing frame is vertically arranged and perpendicular to the connecting rod.

[0012] The working principle of this utility model is as follows:

[0013] When processing the steel billet, the steel billet is placed on a conveyor roller, which is driven by a first motor to rotate and transport the steel billet into a processing chamber. After the steel billet arrives at the processing chamber, the first motor is turned off, and an external high-pressure water gun is used to wash away the oxidizing medium (mainly impurities attached after phosphorus oxidation) attached to the surface of the steel billet. At the same time, the servo motor is turned on, and the servo motor drives the bidirectional screw rod counterclockwise to rotate. Because the two sides of the bidirectional screw rod are provided with threads in opposite directions, when the bidirectional screw rod rotates in the same direction, the two load-bearing frames threadedly connected to the two ends of the bidirectional screw rod approach each other. After the scrapers provided on the assembly frame fixed at the bottom of the load-bearing frame contact the two sides of the steel billet, the servo motor is turned off, the hydraulic cylinder is turned on to work, and the extended end of the hydraulic cylinder extends, driving the connecting rod to move in the vertical direction. The load-bearing frame connected to the connecting rod drives the scraper on the cleaning frame to move up and down to scrape off the oxidizing medium attached to the surface of the steel billet, and the scraped attached medium is cleaned away by the high-pressure water gun. After scraping, turn on the servo motor to drive the bidirectional screw to rotate clockwise. At this time, the two load-bearing frames move away from each other, that is, leave the surface of the billet. Finally, turn on the first motor to drive the conveying roller to send the billet out of the processing bin.

[0014] As a further improvement of the present invention, the bottom of the support frame is provided with reinforcing ribs connected to the top of the processing chamber.

[0015] The support frame is further fixed by using reinforcing ribs, thereby improving the stability of the support frame.

[0016] As a further improvement of the present invention, the scrapers are arranged at the upper and lower ends of the inner side surface of the cleaning frame.

[0017] The double scraper setting can improve the removal efficiency and removal effect of the medium attached to the surface of the steel billet.

[0018] As a further improvement of the present invention, the protruding end of the hydraulic cylinder is fixedly connected to a "T"-shaped frame, which passes through the middle of the connecting rod and is fixedly connected to the top of the connecting rod; a through hole is provided at the bottom of the "T"-shaped frame for placing a bidirectional screw rod, and the bidirectional screw rod is divided by the "T"-shaped frame, and threads in opposite directions are provided on the rod bodies on both sides.

[0019] Using a "T"-shaped frame to support the middle part of the bidirectional screw rod can improve the load-bearing capacity of the bidirectional screw rod and avoid damage during work.

[0020] As a further improvement of the present invention, the top of the load-bearing frame is connected to a slider by bolts, the middle of the slider is threadedly connected to the bidirectional screw rod, and the slider is rectangular and matches the internal shape of the connecting rod.

[0021] A removable slider is provided on the top of the force-carrying frame to facilitate the later replacement of the force-carrying frame. When the force-carrying frame needs to be replaced, it is only necessary to separate the force-carrying frame from the slider for replacement without removing the bidirectional screw rod.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. The utility model uses an automatically arranged load-bearing frame to carry a cleaning frame. While the medium attached to the surface of the steel billet is cleaned by a high-pressure water gun, the scraper is used to scrape off the medium attached to the surface of the steel billet, which greatly improves the effect of removing impurities on the surface of the steel billet and improves the cleaning efficiency.

[0024] 2. The auxiliary components of the utility model have a simple structure and are easy to install. They adopt a multi-component individually detachable structure, which is convenient for later maintenance and replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The working principle of this embodiment is as follows:

[0036] When processing the steel billet, the steel billet is placed on the conveying roller 4, which is driven by the first motor 3 to rotate and send the steel billet into the processing chamber 5.
