Novel refractory material and production method thereof

Abstract

The invention discloses a novel refractory material and a production method thereof. The novel refractory material is prepared by mixing the following components in parts by weight: 38-45 parts of quartz sand, 35-45 parts of high bauxite, 1-4 parts of water glass, 1-4 parts of borax, 3-10 parts of quartz powder and 5-15 parts of special organic matters. The production method comprises the following steps: preparing materials according to the parts by weight of the components and grinding the components into dry powder materials for later use; adding other materials except for the water glass and dry-mixing for 3-5min; adding 6-7% of water, stirring and mixing for 5-8min; and adding the water glass, stirring and mixing for 4-5min so as to prepare the novel refractory material. The refractory material disclosed by the invention, which is prepared from various elements, is applicable to the furnace lining of a smelting furnace, the ladle lining of a casting ladle as well as repair of the smelting furnace and the casting ladle. By virtue of the technology disclosed by the invention, the coatings of the smelting furnace and the casting ladle, which are 80-150mm thick, can be dried with slow fire. The refractory material can be continuously used for multiple times, and is safe and reliable; and the refractory material can be used for avoiding the penetration of the furnace body or the casting ladle, the refractory material can be used for improving production efficiency and also can be used for guaranteeing safe production.

Description

technical field [0001] The invention relates to a refractory material, in particular to a refractory material for smelting and pouring. Background technique [0002] In foundry production, when smelting and pouring, the furnace lining and lining are commonly used with a single refractory material, and quartz sand and water glass are generally used for mixing. Every time the intermediate frequency furnace is built, there are at most 20-30 furnaces, which will cause the furnace body to collapse and must be replaced, and at the same time cause the furnace body to break through the furnace. Ladles and ladles are also coated with quartz sand and water glass. At most, molten steel or molten iron will be replaced every 3-5 ladle times, which wastes a lot of materials and manpower and seriously affects production. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, provide a new refractory material that can be ...

AI Technical Summary

Problems solved by technology

Every time the intermediate frequency furnace is repaired, there are at most 20-30 furnaces, which will cause the furnace body to collapse and must be replaced, and at the same time cause the furnace body to break through the furnace.

Ladles and ladles are also coated with quartz sand and water glass. The most molten steel or molten iron needs to be replaced after 3-5 ladle times, which wastes a lot of materials and manpower and seriously affects production.
