Embodiment 1

[0023] Firstly, prepare according to the ratio and particle size of the pellets and powders used in the alloy of the present invention combined with the non-burning slide plate given in the embodiment of Table 1.

[0024] The preparation method is:

[0025] After batching each ingredient according to the specified ratio, pre-mix all the powder materials, carbon materials, and admixtures in the pre-mixing equipment to make a mixed powder for later use; then use a large wet mill to mix according to the following feeding sequence : Put the aggregate into the mixer and knead for 3-5 minutes, add the binder (4.5% phenolic resin) and knead for another 6 minutes, then add the above-mentioned prepared mixed powder and knead for 35 minutes, and discharge; use 1000 The bricks are formed by a 1-ton friction press, and the bricks are dried at 180°C for 30 hours, and finally hooped, ground, coated, and packaged to obtain an alloy-bonded non-burning skateboard. See Table 2 for the inspecti...

Abstract

The invention belongs to the technical field of steelmaking refractory materials, specifically relates to a refractory material product for controlling the flow rate of molten steel in a steelmaking process, namely a sliding plate brick, and in particular relates to an alloy combined unfired sliding plate brick. The alloy combined unfired sliding plate brick consists of 55-70% of aggregate, 20-35% of powder, 3-8% of carbon material, 2-7% of alloy additive and 4-15% of admixture. The sliding plate brick is prepared by adopting an unfiring process; the aluminum-magnesium alloy additive is added in the sliding plate brick, so that the sliding plate brick has a super strong anti-oxidation effect and the toughness of a sliding plate is enhanced; and the thermal shock resistance of the sliding plate brick is improved by introducing a nano high-purity graphite material. The produced alloy combined unfired sliding plate has a good use effect, the procedures are simple, the firing cost is saved, and the harm to the environment is reduced.

Description

technical field [0001] The invention belongs to the technical field of refractory materials for steelmaking, and specifically relates to a sliding brick, a refractory product used to control the flow of molten steel in the steelmaking process, especially an alloy-bonded non-burning sliding plate. Background technique [0002] As a functional refractory material for steelmaking, the use conditions of skateboard bricks are harsh, and it has always been an important research topic to improve the number of times and safety of skateboards. For a long time, the main materials of domestic and foreign skateboards are aluminum carbon, aluminum zirconium carbon, and magnesium spinel. In terms of technology, they are generally divided into firing and impregnation baking process, non-fired dipping and baking process, and non-burning and non-immersing process. Most of the medium and large ladles and export slides are fired products. The firing process and dipping and baking process have...
