Abstract

The invention belongs to the field of baking castable materials, and particularly discloses a quick baking castable material containing SioxX Zero and application of the quick baking castable material in the aluminum industry. The quick baking castable material is prepared from the following raw materials in parts by weight: 50-70 parts of mullite, 10-20 parts of bauxite, 5-10 parts of calcined alumina powder, 3-12 parts of silicon micro powder, 3-9 parts of water 1-3 parts of SioxX Zero, and 0.05-0.15 part of explosion-proof fiber. The rapid baking castable containing SioxX Zero disclosed by the invention has excellent high-temperature performance and excellent thermal shock resistance stability, can be rapidly baked, realizes rapid baking of aluminum melting furnace castable in the aluminum industry for the first time, can shorten the time by 2 / 3, greatly shortens the baking time, saves time cost and energy cost for customers, and has a remarkable effect.

Description

technical field [0001] The invention belongs to the field of baking castables, and specifically discloses a quick-baking castable containing Seker Z and its application in the aluminum industry. Background technique [0002] The aluminum smelting furnaces involved in the processing of aluminum and aluminum alloys mainly include reverberatory furnaces, rotary drum furnaces, etc. The operating temperature is generally 700-1000°C, and the refractory materials used are usually cement-based castables. This is because the cement bond can play an irreplaceable strength support role in this temperature range. In addition, the cement binding system is a mature system of castables at present, so it is widely used. The mechanism of cement bonding is mainly through the hydration of cement to generate strength. It has the characteristics of fast hardening and high strength. However, calcium ions are brought into the cement and react with aluminum-silicon at high temperature to form a l...
