Description

Technical Field

[0001] The utility model relates to the technical field of magnesia-carbon brick performance testing, in particular to a magnesia-carbon brick performance testing platform. Background Technique

[0002] Magnesia-carbon brick is a high-performance refractory material, mainly made of magnesite and graphite powder as raw materials, and is produced through processes such as mixing, molding, and sintering. Magnesia-carbon brick has good refractory performance and chemical stability under harsh environments such as high temperature, high pressure, and corrosion, and is widely used in industrial fields such as iron and steel, non-ferrous metal smelting, and glass. In order to ensure the quality and performance of magnesia-carbon brick products, various performance tests must be carried out. The testing platform is a device used to conduct various performance tests on materials or products. Through the testing platform, the performance of magnesia-carbon brick such as compressive strength, refractoriness, corrosion resistance, and thermal conductivity can be accurately measured and evaluated;

[0003] The applicant found through retrieval that the Chinese patent discloses "a testing platform", and its publication (announcement) number is "CN212721315U". This patent mainly includes a loading plate, a processor, and an alarm module. The loading plate is provided with a laser emitter and a laser receiver, and the laser emitter and the laser receiver are arranged opposite to each other. The processor is electrically connected to the alarm module and the laser receiver respectively. During actual use, the height of the laser emitter is adjusted according to the height of the tested product to be detected. The laser emitter is turned on, and the laser emitted by the laser emitter hits the laser receiver. The tested product is placed on the loading plate and between the laser emitter and the laser receiver. The tested product or the laser emitter and the laser receiver are moved so that the tested product passes between the laser emitter and the laser receiver. However, the original equipment may not be able to limit and fix the test and reinforce the tested material. Therefore, we propose a magnesia-carbon brick performance testing platform.

[0031] Example 1.

[0032] Example 2. Please refer to the attached Figure 1 - attached Figure 5 , through the setting of the moving plate 35, the moving plate 35 can move forward or backward by the rotation of the lead screw 37, which can adapt to magnesia-carbon bricks of different specifications.

[0034] Specifically, a lead screw 37 is provided outside the U-shaped plate 34, and the rotation of the lead screw 37 drives the moving plate 35 to move back and forth, which can clamp magnesia-carbon bricks of different specifications and adapt to workpieces of different sizes and shapes, improving the scope of use and flexibility.

At the same time, the electro-hydraulic rod can display the pressure used and save and feedback it to an external computer, facilitating the staff to record the pressure received by the magnesia-carbon brick blocks.

[0035] Working principle:

[0036] First, the staff drives the screw 37 to rotate through the steering wheel 311, and the movable plate 35 will move forward or backward with the rotation of the screw 37, and then drive the U-shaped plate 34 through the rotating column 32, and use the gear 39 on the U-shaped plate 34 to fit the rack on the fixed frame 24 to reach a limit, and then the pressure of the electric hydraulic press 14 is released downward along with the push rod 15, and the pressure value is recorded each time. At this point, the entire workflow ends.
