The test device comprises a vibration table main body and a control and acquisition system. An oil storage tank which is arranged on the upper part of a support is connected with an oil conveying groove with liquid level sensors through a valve; a step motor is connected with a vibration plate through an eccentric wheel and a connection rod; pressure sensors are connected with pressure testing holes on the vibration plate; an observation window is parallel to the vibration plate; the lower part of the support is provided with an oil receiving tank which is arranged on an electronic balance; according to the control and acquisition system, a master computer performs configuration setup of running parameters, and a programmable logic controller controls the step motor to rotate according to the set parameters; and the pressure sensors, the liquid level sensors and the electronic scale acquire oil liquid pressure and liquid level and quality signals in the vibration process so as to realize the simulative test of process data such as slag runner pressure, liquid level fluctuation, friction and slag consumption in a meniscus area of the continuous casting mold. The test device is simple in structure and easy and convenient to operate; and the test device is provided for physical test of the mold vibration technological process.

Description

technical field [0001] The invention relates to the detection of vibration of iron and steel metallurgy continuous casting crystallizer, in particular to a test device for simulating and detecting the vibration process of continuous casting crystallizer. Background technique [0002] In modern iron and steel metallurgical production, continuous casting plays an important role in the manufacturing process of iron and steel products as a link between the previous and the next, and the continuous casting mold is called " The heart of the continuous casting machine, the molten steel is poured into the mold from the tundish, and under the cooling effect of the copper plate of the mold, it is initially condensed into a continuous casting billet with a certain shell thickness and regular shape, and is continuously pulled out from the lower mouth of the mold. The interaction between mold copper plate-mold slag layer-continuous casting slab shell is an extremely complex dynamic proce...

AI Technical Summary

Problems solved by technology

Among them, the initial conditions are the unique definite solution conditions for calculating the unsteady heat transfer process, which can be given by the actual casting operation conditions; while the boundary conditions that determine the accuracy of the final calculation results are usually difficult to obtain accurately

Therefore, the numerical simulation calculation method is not accurate enough to describe the behavior of the copper plate-shell interface in the meniscus region, and there is a large gap between the theoretical calculation results of the slag channel pressure and friction in the meniscus region and the actual situation.

[0004] At present, this kind of research is still at the above numerical simulation stage, and there is no report on the physical test during the vibration process of the continuous casting mold in the existing literature
