Abstract

The invention provides an aluminum-silicon drainage agent and a preparation method thereof, belonging to the field of unshaped surface refractory materials used in the steelmaking industry. The technical solution of the present invention is: an aluminum-silicon drainage agent, which is composed of ceramic bead sand with a particle size of 0.5-1.2 mm, desert quartz sand with a particle size of 0.3-0.9 mm, phosphorus flake graphite with a particle size of ≤75 μm, and an adhesive It is made by first drying ceramic bead sand and desert quartz sand, then adding phosphorus flake graphite and binder, and stirring in a cylinder mixer to make it. The aluminum-silicon drainage agent of the present invention can effectively increase the casting rate of the product, so that the casting rate of the product can reach more than 98%, and at the same time greatly reduce the cost of the product, effectively reduce the emission of waste gas and dust, clean and environmentally friendly, and adapt to the current steel industry's requirements for product quality, Price and purity requirements of molten steel.

Description

technical field

[0001] The invention relates to metallurgy and belongs to the field of unshaped surface refractory materials used in the steelmaking industry, in particular to an aluminum-silicon draining agent for continuous casting ladle opening and a preparation method thereof. Background technique

[0002] Ladle drainage agent is a refractory material with high temperature resistance, good thermal stability and strong corrosion resistance. It is used to fill the upper nozzle of the ladle during the steel pouring process to prevent the molten steel from entering the nozzle after the ladle is loaded with steel. The drainage agent can fall automatically, and then the molten steel flows into the tundish, so that the continuous casting production can run smoothly and meet the important link of high-speed continuous casting and continuous pouring. It is a necessary refractory material.

[0003] At present, the drainage agents used in domestic and foreign steel mills can be div...
