Abstract

The invention provides a testing device for evaluating static and dynamic erosion resistance of a refractory material. The testing device comprises a heating furnace provided with a bottom platform type furnace door, the bottom of the bottom platform type furnace door is connected with a bottom furnace door lifting motor through a motor lifting shaft, and a crucible capable of containing slag or metal melt is arranged on the bottom platform type furnace door. A refractory material sample fixedly connected with a corundum connecting rod through a graphite rod is arranged in the heating furnace, the corundum connecting rod is fixedly connected with a high-temperature alloy connecting rod, the high-temperature alloy connecting rod is connected with a rotating motor and a lifting motor, and a feeding pipe extending to the position above the crucible is arranged on the heating furnace. And the heating furnace is also connected with a furnace body heating system and an atmosphere protection system. According to the testing device for evaluating the static and dynamic erosion resistance of the refractory material, and a testing method thereof provided by the invention, the test that the refractory material is eroded by the slag and the metal melt respectively can be completed, and the preparation difficulty and the preparation cost of the refractory material can also be reduced.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a test device and a test method for evaluating the static and dynamic corrosion resistance performance of refractory materials. Background technique [0002] Refractory materials serve many fields such as national economy and national defense construction. They are mainly used in the production process of high-temperature industries such as metallurgy, building materials, non-ferrous metals and military industries. They are indispensable and important basic materials for high-temperature industries. plays an irreplaceable role. Among them, refractory materials are used in the largest amount in the metallurgical industry, accounting for about 60% of the total output of refractory materials. [0003] With the continuous implementation of major national construction projects, higher and higher requirements are put forward for the research and development and production...

Problems solved by technology

[0004] However, the present test equipment for static and dynamic slag resistance of refractory materials still has many imperfections. For example, in the prior art, there is a test furnace for static and dynamic slag resistance of refractory materials. , although the device can pass gas into the slag crucible from the upper end through the hollow connecting rod to simulate the erosion of the sample by the slag in the boiling state

However, there are still the following disadvantages: 1. The connection method of the sample is relatively complicated, that is, holes are drilled on the refractory material, and then connected by pins, which increases the cost and difficulty of sample preparation; 2. The device does not have an atmosphere protection system, so about The erosion mechanism of the metal melt on the refractory material cannot be explored; 3. The inside of the device is in a sealed state, and the slag after the reaction cannot be analyzed instantaneously after the experiment. It can only be cooled with the furnace. trait influence

In addition, due to the high hardness of refractory materials, it is difficult to process
