Description

Technical Field

[0001] The utility model relates to the technical field of baking and automatic adding devices, in particular to a protective slag baking and automatic adding device. Background Art

[0002] Protective slag is an important auxiliary material in continuous casting production. It is mainly used to prevent secondary oxidation of molten steel during the continuous casting process. It needs to be added to the upper surface of the molten steel in the crystallizer. It mainly plays the role of heat conduction, lubrication, heat preservation and anti-oxidation. The protective slag is gradually melted into liquid slag from powder particles in the crystallizer. As the ingot is pulled out, it gradually flows out from the gap between the molten steel and the crystallizer. Therefore, the protective slag needs to be continuously added to the crystallizer, added frequently, in small amounts and evenly.

[0003] At present, the common ways of adding protective slag on the market are manual addition and automatic addition by robot. The automation level of most steel companies is not high. Manual addition of protective slag is time-consuming and labor-intensive. The cost of fully automatic robot slag adding equipment is high and difficult to maintain. Since the protective slag is easily affected by moisture and agglomerates, the bubbles formed by water vapor are harmful to steel and it should be kept as dry as possible. The baking of protective slag usually utilizes the heat after gas combustion, which increases the energy consumption cost. Therefore, a protective slag baking and automatic adding device is proposed to address the above problems. Utility Model Content

[0004] The utility model aims to provide a protective slag baking and automatic adding device to solve the problems of wasting manpower in manually adding protective slag, high machine adding cost and high energy consumption cost during baking.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A protective slag baking and automatic adding device comprises a crystallizer, a vibration unit and a tundish, wherein the vibration unit is provided on one side of the crystallizer, the tundish is provided above the crystallizer, the lower part of the tundish is connected with a water outlet, a connecting pipe is provided on the right side of the water outlet, a feeding port is fixedly sleeved in the connecting pipe, a slag adding bucket with upper and lower openings is fixedly connected to the top of the feeding port, an extension steel pipe is fixedly connected to one side of the slag adding bucket, a hollow ball is fixedly connected to one end of the extension steel pipe, a metal rod is fixedly connected to the top of the vibration unit, a groove is provided in the connecting pipe, a baffle is slidably connected to the groove provided in the connecting pipe, a guide block is fixedly connected to the top of the baffle, a protective frame is slidably connected to the outer side of the guide block, a connecting block is fixedly connected to the other side of the baffle, the connecting block and the metal rod are fixedly connected, and a support frame is fixedly connected to one side of the slag adding bucket.

[0007] Preferably, the tundish is provided as a refractory container, the slag hopper is composed of closely packed steel pipes, and the closely packed steel pipes at the slag hopper are interconnected.

[0008] Preferably, the hollow ball is arranged just above the tundish, molten steel is arranged in the tundish, and waste oil is arranged in the hollow ball, the extended steel pipe 8 and the closely spaced steel pipes of the slag hopper.

[0009] Preferably, one end of the metal rod passes through the connecting pipe, and a sealing block is tightly attached to the outer side of the metal rod, and the sealing block is arranged in the connecting pipe.

[0010] Preferably, a rubber layer is fixedly connected inside the protection frame, and the protection frame and the connecting pipe are fixedly connected.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, a crystallizer, a vibration unit, a tundish, a water inlet, a connecting pipe, a slag hopper, a material discharge port, an extended steel pipe, a hollow ball and a support frame are arranged. Since the slag hopper is composed of closely arranged steel pipes that are interconnected and arranged with upper and lower openings, protective slag is added from the upper opening of the slag hopper and material is discharged from the lower opening. Since the slag hopper, the extended steel pipe and the hollow ball are interconnected and waste engine oil is arranged inside, and the hollow ball is arranged just above the tundish, the waste engine oil is heated under the heat radiation of the high-temperature molten steel in the tundish, and the heat is transferred to the protective slag. Compared with the heat after the combustion of coal gas in the prior art, the heat is reduced. The energy consumption cost is reduced. By setting the metal rod, guide block, baffle, groove, protective frame and connecting block, the vibration of the vibration unit drives the metal rod to move up and down in the connecting pipe, and drives the baffle to move up and down at the same time, controls the protective slag to fall evenly and automatically from the connecting pipe to the top of the crystallizer. By utilizing the vibration unit of the crystallizer, the process of adding protective slag does not require additional power, avoiding the waste of manpower and the high cost of fully automatic mechanical equipment. The sealing block set on the outside of the metal rod increases the sealing effect of the connecting pipe. The rubber layer set in the protective frame protects the inner wall of the protective frame from damage. BRIEF DESCRIPTION OF THE DRAWINGS

A baffle 12 is slidably connected in the groove 13 opened in the pipe 5, a guide block 11 is fixedly connected to the top of the baffle 12, a protective frame 14 is slidably connected to the outer side of the guide block 11, a connecting block 15 is fixedly connected to the other side of the baffle 12, the connecting block 15 and the metal rod 10 are fixedly connected, and a support frame 18 is fixedly connected to one side of the slag adding bucket 6. By utilizing the heat radiation of the high-temperature molten steel in the tundish 3, the protective slag is kept in a dry state. By utilizing the vibration unit 2 of the crystallizer 1, the process of adding protective slag does not require additional power, thereby avoiding the waste of manpower and the high cost of fully automatic mechanical equipment.

[0022] The tundish 3 is arranged as a refractory container, and the slag hopper 6 is composed of closely packed steel pipes. The closely packed steel pipes at the slag hopper 6 are interconnected to facilitate heating of the slag hopper 6; the hollow ball 9 is arranged just above the tundish 3, and molten steel is arranged in the tundish 3. Waste oil is arranged in the hollow ball 9, the extended steel pipe 8 and the closely packed steel pipes of the slag hopper 6 to facilitate baking of the protective slag; one end of the metal rod 10 passes through the connecting pipe 5, and a sealing block 16 is tightly fitted on the outside of the metal rod 10. The sealing block 16 is arranged in the connecting pipe 5 to increase the sealing effect of the connecting pipe 5; a rubber layer 17 is fixedly connected to the protective frame 14, and the protective frame 14 and the connecting pipe 5 are fixedly connected, so that the protective slag is not easy to splash out from the groove 13.

[0023] Working process: During the operation of the equipment, the external power supply is energized. When the protective slag baking and automatic adding device is in use, first place this device in a suitable position together with the crystallizer 1. The protective slag needs to be kept as dry as possible when added. The slag adding hopper 6, extended steel pipe 8 and hollow ball 9 are interconnected, and waste oil is arranged inside. The heat radiation generated by the molten steel in the tundish 3 heats the waste oil in the hollow ball 9. Since the slag adding hopper 6 is arranged in a closely packed steel pipe, the slag adding hopper 6 is heated at the same time, so that the protective slag is in a baking state to achieve the purpose of drying. Compared with the heat after the combustion of coal gas in the prior art, the energy consumption cost is reduced. When the protective slag needs to fall to the crystallizer 1, the vibration unit 2 next to the crystallizer 1 is started, and the vibration amplitude of the vibration unit 2 The metal rod 10 is driven to move up and down in the connecting pipe 5. Since the metal rod 10 is fixedly connected to the connecting block 15 and the connecting block 15 is fixedly connected to the baffle 12, the metal rod 10 drives the baffle 12 to move up and down at the same time. At this time, the guide block 11 slides in the protective frame 14, and the protective frame 14 prevents the protective slag from splashing out of the groove 13. When the vibration unit 2 vibrates upward, the baffle 12 moves up, and the protective slag falls and falls to the crystallizer 1. When vibrating downward, the baffle 12 moves down, and the addition of protective slag stops. This cycle repeats. By utilizing the heat radiation of the high-temperature molten steel in the tundish 3, the protective slag is in a dry state. By utilizing the vibration unit 2 of the crystallizer 1, the process of adding protective slag does not require additional power, thereby avoiding the waste of manpower and the high cost of fully automatic mechanical equipment.
