Abstract

The invention provides a stemming utilizing a waste refractory material and a preparation method thereof. The stemming comprises the following raw materials: silicon carbide particles or fine powder, high-temperature fine asphalt powder, Jilin fine clay powder, coke particles, industrial grade corundum particles or fine powder, wherein recovered aluminum and magnesium material particles or fine powder used for an electric furnace is added; and tar serves as a bonding agent. The preparation method comprises the following steps of: preparing the raw materials according to a proportion; after uniformly stirring particle materials in a stirring machine for 1 to 10 minutes, adding 20 to 30 percent of the tar; stirring for 5 to 10 minutes; adding fine powder materials; stirring for 5 to 15 minutes; adding the remaining tar and stirring for 25 to 40 minutes; and extruding by using a stemming extruder and packaging. The stemming has the following advantages: high operating performance, low stemming sintering shrinkage, rapid sintering property, high scour resistance and slag iron erosiveness. The invention provides a way for regenerating and utilizing the waste refractory material, and contributes to saving resources and protecting environment.

Description

technical field [0001] The invention relates to recycling of waste and old refractory materials, in particular to a gun clay utilizing waste and old refractory materials and a preparation method thereof. Background technique [0002] Gun clay is one of the most important consumable materials in blast furnace operation. Its function is to fill in the tap hole when the blast furnace does not produce slag iron solution, so that the tap hole can maintain a sufficient depth. When tapping the blast furnace, the blast furnace mud in the tap hole is drilled, and the iron slag solution is discharged out of the furnace through the tunnel. The tap hole of the blast furnace must be repeatedly opened and filled every day. The average annual consumption of blast furnace mud in my country is 1,000 tons per blast furnace. There are more than 3,000 blast furnaces, and the demand for blast furnace clay is 3 million tons per year. [0003] The existing raw materials for gun clay mainly include...
