Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0020] The present invention provides the following embodiments Example 1 The embodiment of the present invention provides a method for preparing a quick-drying explosion-proof and wear-resistant castable, such as Figure 1 As shown, the preparation method comprises the following steps: S1. Raw material mixing: alumina powder, high aluminum fine powder, sintering agent, ultrafine powder, water reducing agent, retarder and explosion-proof agent are uniformly mixed in a certain proportion; S2, stirring: adding the mixed raw materials into the preparation device for stirring, adding calcium aluminate cement after stirring evenly, continuing to stir evenly, then adding an appropriate amount of tap water, stirring evenly again, and monitoring the mixing components used for stirring in the preparation device at the same time; S3. Use: Take out the mixed finished material and use it within 30 minutes.

[0021] The working principle and beneficial effects of the above technical solution are as follows: alumina powder particles have excellent wear resistance and corrosion resistance, and can withstand strong impact and wear. High-aluminum fine powder can improve the refractoriness of castables, enhance the physical properties and chemical stability of castables, and sintering agent can promote the bonding between raw material particles, further improve the refractoriness and durability of castables. Ultrafine powder can fill the tiny pores in refractory castables, reduce apparent porosity, and increase bulk density, which can not only reduce the amount of water used for mixing, but also improve the fluidity and construction properties of castables. Water reducer can effectively reduce the water-cement ratio of castables and reduce the amount of water added during mixing during construction. While keeping the fluidity of castables unchanged, water reducer can release the encapsulated free water, thereby reducing the amount of water used for construction. Retarder can delay the setting time, thereby improving construction performance and extending the working window period. Explosion-proof agent can prevent castables from bursting in dry and high temperature environments. The mixed finished material has the characteristics of quick drying, so it needs to be used up within 30 minutes. The percentages of alumina powder, high-alumina fine powder, sintering agent, ultrafine powder, water reducing agent, retarder and explosion-proof agent in the total weight of raw materials are 54.7%, 36.5%, 3.5%, 4.5%, 0.3%, 0.3% and 0.2% respectively. Among the alumina powder, the particle size of 0 to 1 mm accounts for 20%, the particle size of 1 to 3 mm accounts for 30%, the particle size of 3 to 5 mm accounts for 15%, and the particle size of 5 to 10 mm accounts for 35%. The high-alumina fine powder with a particle size of less than 0.044 mm accounts for 75% of the total amount of fine powder, and the particle size between 0.044 mm and 0.088 mm accounts for 25% of the total amount of fine powder. The weight ratio of high-alumina cement added to the raw material is 4:3, and the weight ratio of tap water added to the raw material is 2:3. The sintering agent is bentonite, the ultrafine powder is silica fume powder, the water reducing agent is sodium tripolyphosphate, the explosion-proof agent is metallic aluminum powder, and the retarder is triisopropanolamine; The preparation device used in the preparation method will further improve the mixing uniformity of the castable, and monitor the mixing component 25 of the preparation device during the stirring process to prevent the mixing component 25 from malfunctioning, resulting in the failure of the preparation of the castable and the contamination and waste of various raw materials.

When the actual safety torque coefficient of the stirring shaft 256 is greater than or equal to the rated safety torque coefficient of the stirring shaft 256, the control module controls the alarm module to issue an alarm and at the same time controls the preparation device to stop working. When the actual safety torque coefficient of the stirring shaft 256 is less than the rated safety torque coefficient of the stirring shaft 256, the preparation device works normally.

[0024] Example 3 Based on Example 2, the calculation module 1 calculates based on the following formula 1: ; is the actual safety torque factor of the stirring shaft 256, is the transmission efficiency between the second motor 263 and the stirring shaft 256, is the average density of the solid particle raw material, is the density of water, is the diameter of the stirring shaft 256, is the actual rotation speed of the stirring shaft 256, is the actual rotation speed of the mixing tank 251, is the mixing coefficient, is the diameter inside the mixing tank 251, is the average diameter of the solid particle raw material, is the liquid viscosity, is the total volume of solid particle raw materials, is the volume in the mixing tank 251, is the rated torque of the stirring shaft 256, is the total mass of solid particle raw materials and water, is the working time of the stirring shaft 256.

When the actual safety torque coefficient of the stirring shaft 256 is greater than or equal to the rated safety torque coefficient of the stirring shaft 256, the control module controls the alarm module to sound an alarm and controls the preparation device to stop working. When the actual safety torque coefficient of the stirring shaft 256 is less than the rated safety torque coefficient of the stirring shaft 256, the preparation device works normally.
