Description

Technical Field

[0001] This invention relates to the theory of power consumption of thick plate cooling beds, and more specifically, to a method and apparatus for calculating the power consumption per ton of steel on a thick plate workshop cooling bed. Background Technology

[0002] The medium-thick plate cooling bed is a stepping type, mainly composed of fixed beams, movable beams, and lifting and traversing transmission devices. The lifting mechanism of the entire cooling bed is divided into four sections; the left and right sections can operate simultaneously or independently, while the front and rear sections are connected by a hinge point in the middle of the movable beam. The traversing mechanism of the cooling bed is divided into left and right sections, which can operate simultaneously or independently. The fixed and movable beams of the cooling bed have a grid structure and are arranged alternately.

[0003] The lifting and lateral movement are independent, with a rectangular cycle in motion. The movable beam and grid are vertically lifted by the lifting transmission mechanism, lifting the steel plate away from the fixed beam. Then, the lateral movement transmission drives the swing arm mechanism to swing and pull the lateral beam forward, conveying the steel plate. The movable beam and grid then descend vertically, placing the steel plate onto the grid on the fixed beam. The movable beam and grid then retract to their original position, completing one cycle of plate feeding. See [link to detailed operation process] for more information. Figure 2 .

[0004] In traditional theoretical calculations, the running trajectory of the cooling bed is quite complex. In the lifting mechanism, the moving beam is lifted and lowered through the support between the wedge-shaped rail and the support roller. The contact geometry between the wedge-shaped rail and the support roller is complex, making the calculation of the motor power for the lifting mechanism also complicated. The cooling bed traversing mechanism is a typical crank-rocker mechanism, and the theoretical derivation for calculating the power of the traversing motor is also complex. Therefore, accurately calculating the power consumption per ton of steel on the cooling bed in a thick plate workshop is difficult. Thus, existing technology lacks a relatively accurate solution for calculating the power consumption per ton of steel on the cooling bed in a thick plate workshop. Summary of the Invention

[0129] W = W1 + W2 + W3 + W4 + W5

[0130] Where W is the total work done by the cooling bed on the steel plate, in kW·h.

[0131] In one embodiment of the present invention, step S104 above, which calculates the power consumption per ton of steel based on the work done by the lifting device of the movable beam, the work done by the load translation, the work done by the unloaded translation, the work done by the lifting beam, the work done by the trolley moving the steel plate laterally and returning unloaded, the load of the cooling bed, and the weight of the steel plate, includes:

[0132] The electricity consumption per ton of steel is calculated using the following formula:

[0133]

[0134] Where Q is the power consumption per ton of steel, W1 is the work done by the lifting device of the movable beam, W2 is the work done by the load translation, W3 is the work done by the unloaded translation, W4 is the work done by the lifting beam, W5 is the work done by the trolley moving laterally with the steel plate and returning without load, Q g Q is the weight of the steel plate. f For cooling bed load.

[0135] In one specific embodiment of this invention, taking a 4200mm medium-thick plate project as an example, to accurately calculate the electrical energy consumed by the cooling bed when conveying steel plates, the known parameters of the cooling bed and steel plates are first input. The electricity consumption per ton of steel is then calculated according to the above formula, resulting in 0.168 kW·h / t. Based on an annual output of 1.6 million tons, the cooling bed consumes approximately 269,000 kWh per year. This demonstrates that this invention provides a calculation method for accurately measuring the annual electricity consumption of the cooling bed. Furthermore, changes to the structure and corresponding parameters of the cooling bed will affect the calculation results; therefore, this invention also provides technical support for the optimized design of the cooling bed.

[0136] This invention proposes for the first time a method for calculating the power consumption per ton of steel when conveying steel plates on a cooling bed. During the steel plate conveying process, the cooling bed may be fully covered with steel plates or have only a small number of plates. All these plates contribute work during lifting and lateral movement. Calculating the work done by a single steel plate during lifting, lateral movement, and lowering requires an assumption. This invention proposes a cooling bed surface coverage rate parameter to provide a basis for the cooling bed load. Simultaneously, the conveying work is divided into three stages. Based on the basic parameters, the work done by the cooling bed in each of the three stages can be calculated separately. The cumulative work done in each stage is the total work done by the steel plate during the cooling bed conveying process. Dividing the total work by the mass of the steel plate yields the power consumption per ton of steel conveyed on the cooling bed.

[0137] As can be seen from the above embodiments, the technical solution of the present invention addresses the process of conveying steel plates on a cooling bed in a thick plate workshop. Based on the principle of work done by the steel plate during its operation on the cooling bed, a formula for calculating the electrical energy consumed by a steel plate during its conveying process is derived. This formula is a fully parameterized calculation, capable of accurately calculating the electrical energy consumed by steel plates of different sizes on various specifications of cooling beds. It provides theoretical support for calculating the actual power consumption of the cooling bed and also offers a reference for optimizing the structure of the cooling bed and reducing energy consumption.

[0138] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0139] Based on the same inventive concept, embodiments of the present invention also provide a device for calculating the power consumption per ton of steel on a cooling bed in a thick plate workshop, which can be used to implement the power consumption calculation method for a ton of steel on a cooling bed in a thick plate workshop described in the above embodiments, as described in the following embodiments.
