Attapulgite and pyroclastic rock basic firebrick

Abstract

The invention discloses an attapulgite and pyroclastic rock basic firebrick. According to the technical scheme, the attapulgite and pyroclastic rock basic firebrick is characterized by comprising high-viscosity attapulgite clay powder, dolomite and attapulgite clay tailings, pyroclastic rock mixture, magnesite, serpentine, bauxite, gangue and bentonite tailing. The materials of the attapulgite and pyroclastic rock basic firebrick are mixed, pressed, air-dried, roasted and cooled and are packed to obtain the finished attapulgite and pyroclastic rock basic firebrick. The attapulgite and pyroclastic rock basic firebrick is high in refractoriness and high in basic slag resistance. Various wastes are used to make the attapulgite and pyroclastic rock basic firebrick, so that resource utilization rate can be increased, waste is turned into wealth, occupied land can be reduced, environment can be protected and purified, energy resources can be economized, production cost is lowered, and economic benefit is increased. The attapulgite and pyroclastic rock basic firebrick is applicable to projects such as basic steel furnaces, ferrous metals smelting furnaces and cement kilns.

Description

technical field [0001] The invention relates to a refractory material, in particular to an attapulgite pyroclastic rock basic refractory brick. Background technique [0002] Alkaline refractories mainly refer to refractories with magnesium oxide and calcium oxide as the main components. Alkaline refractories have strong corrosion resistance to alkaline slag. [0003] 80% of my country's mineral resources are associated mines, a large amount of valuable resources are stored in tailings, and tailings stockpiles require a large amount of land. Many tailings ponds have been used beyond the time limit or overloaded, or even operated in violation of regulations, which has caused great safety hazards in the tailings ponds and posed a serious threat to the property and life safety of people in surrounding areas. [0004] In addition to attapulgite, attapulgite clay often contains minerals such as bentonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate. [0005] Pyro...

AI Technical Summary

Problems solved by technology

[0005]Pyroclastic rocks coexist with attapulgite clay deposits, and pyroclastic rocks are mostly in the upper layer of attapulgite clay deposits, and some attapulgite clay deposits The thickness of the pyroclastic rock layer in the upper layer of the mining area is as high as tens of meters. During the mining process of the attapulgite clay, the pyroclastic rock in the upper layer of the attapulgite clay mining area is discarded as waste. According to field investigations, every ton of attapulgite clay mining Rodstone clay produces more than 30 tons of pyroclastic rocks. Calculated at an annual output of 150,000 tons, the pyroclastic rocks produced are as high as 4.5 million tons. They have not been utilized for many years, and the entire mining area is re-accumulated everywhere. Pyroclastic rock mixture, causing serious waste of resources and economic losses
