Description

Technical Field

[0001] The utility model belongs to the field of supplying a demoulding agent for grid continuous casting, and in particular relates to a demoulding agent supplying system for grid continuous casting. Background Art

[0002] The continuous casting production method has gradually replaced gravity casting, mesh drawing and other production methods with its advantages of simplified production process, mechanization and high degree of automation, and has become the mainstream method of grid production. During the continuous casting process, a release agent needs to be applied to the moving mold to ensure that the grid can be demolded smoothly and to prevent the grid from sticking to the moving mold, causing wire drawing and burrs on the grid. The coating of the release agent will directly affect whether the thickness of the grid is uniform, so the uniform coating of the release agent on the moving mold is very important. The existing release agent mainly adopts air pressure to supply oil to the horizontally arranged oil supply channel, and then applies it to the movable mold from the oil outlet of the oil supply channel. The air pressure is unstable, resulting in uneven oil supply. In addition, since the oil supply channel is in a horizontal state, the release agent is easily accumulated near the oil inlet of the oil supply channel, and the capacity of the release agent discharged from the oil outlet at the far end of the oil inlet on the oil supply channel is difficult to guarantee, resulting in the inability to accurately control the discharge amount of the release agent from each oil outlet, resulting in uneven coating of the release agent on the movable mold, affecting the quality of the grid, and even causing mutual wear between the movable mold and the fixed mold. If an ordinary oil pump is used for oil supply, a larger pressure can be provided for the oil supply channel to ensure that the oil outlet at the far end of the oil inlet has enough release agent, but the output of the oil pump is large, and the amount of release agent required for the movable mold is small. Therefore, it is necessary to set up multiple pipelines for quantitative supply and return of excess release agent, which is difficult to adjust, has a complex structure and requires more accessories. Utility Model Content

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0020] Specific implementation examples Figure 1-3 As shown, the grid continuous casting release agent supply system includes an oil tank 1, an oil outlet unit 2 and a coating unit 3 connected to the oil outlet unit 2, the oil tank 1 and the oil outlet unit 2 are connected by an oil delivery pipeline 4, and an oil delivery drive unit 5 is arranged on the oil delivery pipeline 4. The key is that the oil delivery drive unit 5 is a peristaltic pump, the coating unit 3 is located above the movable mold 6, the oil outlet unit 2 includes a frame 21, an oil outlet channel 22 arranged on the frame 21 and axially parallel to the movable mold 6, and a group of flow regulating valves 23 arranged at intervals along the oil outlet channel 22, the inlet of the flow regulating valve 23 is connected to the oil outlet channel 22, and the outlet is connected to the coating unit 3. During operation, the release agent in the oil tank 1 is made to flow to the oil outlet unit 2 along the oil delivery pipeline 4 with the help of the oil delivery drive unit 5, and then the oil outlet unit 2 outputs the release agent to the coating unit 3, wherein the oil delivery drive unit 5 selects a peristaltic pump, which can accurately control the supply flow of the release agent, so that the release agent is evenly and stably output to the oil outlet channel 22 in the oil outlet unit 2, and a group of flow regulating valves 23 are arranged on the oil outlet channel 22. With the help of the flow regulating valves 23, the flow rate of the release agent output from the oil outlet channel 22 to various parts of the coating unit 3 is controlled, so as to ensure that the coating unit 3 evenly applies the release agent to the movable mold 6, and ensure that the thickness of the release agent at various places on the movable mold 6 is uniform, which is helpful to improve the quality of the grid; on the other hand, the flow rate of the peristaltic pump can be accurately controlled to realize small flow delivery. Only one oil delivery pipeline 4 is provided between the oil tank 1 and the oil outlet unit 2, and there is no need to set a return pipeline. The structure is simple and easy to maintain.

[0021] The oil outlet channel 22 is in an inverted V-shaped structure, the end of the oil delivery pipeline 4 is connected to the upper end of the oil outlet channel 22, and the flow regulating valve 23 is respectively connected to the bottom of both sides of the oil outlet channel 22. Under the influence of gravity, the release agent output by the oil delivery pipeline 4 flows from the top of the oil delivery pipeline 4 to the bottom of both sides and passes through each flow regulating valve 23, and is discharged along the flow regulating valve 23 arranged on the oil outlet channel 22. There is no need for the oil delivery drive unit 5 to provide excessive pressure to the oil outlet channel 22, so that the end of the oil outlet channel 22 away from the end of the oil delivery pipeline 4 can be guaranteed to have sufficient release agent, further reducing the power and output flow of the oil delivery drive unit 5, and meeting the requirements of small-dose supply and coating of release agent on the movable mold 6.

[0022] The coating unit 3 includes a mounting frame 31 connected to the flow regulating valve 23 and an oil absorbing coating member 32 disposed on the mounting frame 31, wherein the oil absorbing coating member 32 is a felt, which has good absorption and storage capacity and can absorb and store the release agent. The release agent seeps out from the felt and is applied to the movable mold 6, thereby improving the uniformity of the release agent on the movable mold 6. The lower end of the mounting frame 31 is provided with a mounting groove 33, and the oil absorbing coating member 32 is fixedly connected to the mounting frame 31 by means of the mounting groove 33. The mounting frame 31 is provided with an oil inlet hole 34 which is respectively connected to the mounting groove 33 and the flow regulating valve 23. The release agent drips from the discharge port of the flow regulating valve 23 along the oil inlet hole 34 onto the oil absorbing coating member 32, and the oil absorbing coating member 32 absorbs the dripping release agent and applies it to the movable mold 6 in an exuding manner. The structure is simple and the coating of the release agent is more uniform.

[0023] The lower end of the oil-absorbing coating member 32 is in an arc-shaped structure, and the arc surface of the arc-shaped structure overlaps the upper end of the movable mold 6. Specifically, the movable mold 6 rotates in the clockwise direction, and the lower end of the oil-absorbing coating member 32 hangs down from a high place and then rises upward in the counterclockwise direction to form an arc-shaped structure. During the rotation of the movable mold 6, friction is generated with the lower end of the oil-absorbing coating member 32, and the release agent in the oil-absorbing coating member 32 is coated on the movable mold 6. A slight extrusion is generated between the oil-absorbing coating member 32 and the movable mold 6, so that the oil-absorbing coating member 32 and the movable mold 6 are in surface contact, thereby improving the uniformity of coating.

[0024] A group of observation holes 35 connected to the oil inlet hole 34 are provided on the side wall of the mounting frame 31. The observation holes 35 are matched with the flow regulating valve 23. The flow of the flow regulating valve 23 can be visually observed through the observation holes 35, which is convenient for the staff to adjust the flow of each flow regulating valve 23 to ensure that the oil absorption coating member 32 can achieve uniform coating on the movable mold 6. A transparent baffle is also provided on the observation hole 35, which can not only enable the staff to observe the flow of the flow regulating valve 23, but also prevent the release agent discharged from the flow regulating valve 23 from splashing to the outside to cause pollution to the environment or equipment.

[0025] The oil delivery pipeline 4 is also provided with a filter 7 and a main valve 8. The filter 7 is located between the oil tank 1 and the peristaltic pump. The main valve 8 controls the cutting off or supply of the release agent in the oil tank 1. The filter 7 filters the release agent output from the oil tank 1 to prevent impurities in the release agent from passing through the peristaltic pump and the oil absorption coating 32 to cause damage to the peristaltic pump or affect the quality of the grid.

[0026] During operation, open the main valve 8 and the peristaltic pump, adjust the flow rate of the peristaltic pump to match the demand of the movable mold 6 for the release agent, observe the flow rate of the flow regulating valve 23 through the observation hole 35 and adjust it, and finally start the movable mold 6 and the fixed mold for grid continuous casting.

[0027] The utility model relates to a grid continuous casting release agent supply system, which utilizes the cooperation of a peristaltic pump and an oil outlet channel 22 of an inverted V-shaped structure. There is no need for an oil delivery drive unit 5 to provide a large pressure to the oil outlet channel 22, and a reflux pipeline is provided to cooperate to ensure that there is sufficient release agent for output at the flow regulating valves 23 at various locations. The flow control of the peristaltic pump is accurate and easy to adjust. The release agent is delivered to the oil outlet channel 22 at a small flow rate. The release agent passes through the flow regulating valves 23 on the oil outlet channel 22 under the action of gravity, thereby achieving uniform coating of the release agent on the movable mold 6, reducing the wear between the movable mold 6 and the fixed mold, and effectively improving the quality of the grid.
