Problems solved by technology

Although this method can reflect the fluidity of the material to a certain extent, its test method deviates from reality and cannot reflect the real flow state of the sprayed castable in the pipeline, which often misleads the production staff and causes losses to the enterprise

Embodiment 1

[0043] In this embodiment, the inner diameters of the vertical pipe 11 and the horizontal pipe 12 of the injection castable working performance testing device 100 are 75mm and 40mm respectively, and the lengths are 300mm and 800mm respectively. In the method of testing the working performance of the injection castable using this device, each time 3Kg of the injection castable is loaded into the vertical pipeline 11 and the connecting pipeline 13, and the valve 50 is opened after standing for 15 seconds. At the same time, the constant pressure applied to the piston 20 by the adding device 40 is P 1 = 1 MPa.

[0044] Please also refer to figure 2 , observing the cured and dried spray castable A in the horizontal pipe 12, it can be seen that the large particles of the spray castable A are concentrated in the lower part of the horizontal pipe 12, and the matrix slurry is distributed in the upper part, and serious segregation occurs. In addition, changing the constant pressure a...

Embodiment 2

[0046] In this embodiment, the working performance of the sprayed castable B is tested using the working performance test device 100 and parameters described in Example 1. Please also refer to image 3 , observing the spray castable B in the horizontal pipe 12 after curing and drying, it can be seen that the particle distribution of the spray castable B in the horizontal pipe 12 is relatively uniform, and no obvious segregation phenomenon is observed. There is a thin layer of lubricating layer in the place, which shows that the spray castable B works well in the horizontal pipe 12. In addition, the mathematical relationship between pressure and flow rate P=K is obtained by changing the pressure 0 +μ f(V),K 0 If it matches well with μ, it means that the injection castable B is suitable for transportation in the pipeline.

[0047] The working performance test device and test method of the injection castable provided by the present invention can simulate the flow of the inject...

Abstract

The invention provides a spraying castable working performance test device and test method. According to the spraying castable working performance test device and test method, the flow situation of the spraying castable in a pipeline can be simulated; according to the difficulty degree of flow and the distribution state of particles during the flow process, the blocking situation and segregation situation of the spraying castable are visually reflected. The spraying castable working performance test device and test method are close to practical applications, visual and reliable in obtained results, can effectively evaluate the conveying performance of the spraying castable in the pipeline, provide an evaluation standard for the design of the spraying castable so as to optimize the configuration of the spraying castable and improve the working performance and using performance.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of refractory castables, in particular to a test device for evaluating the working performance of injection castables and a test method using the device. [0003] 【Background technique】 [0004] Due to the advantages of simple production process, convenient construction and low energy consumption, monolithic refractory materials are widely used in ironmaking, steelmaking, building materials, nonferrous metals and other fields, and become the development direction of future refractory materials. With the performance requirements of industrial use, the construction methods are becoming more and more diversified, and the types of monolithic refractory materials are also increasing day by day. In recent years, due to the advantages of low labor intensity, high construction efficiency and long-distance pumping, spray castables have been widely used in blast furnaces, blast furnace tapping channels, torped...
