Refractory material with enhanced toughness

Abstract

The invention provides a refractory material with enhanced toughness, and relates to the field of refractory materials. The refractory material with enhanced toughness comprises quartz sand, calcium oxide, magnesium oxide, manganese oxide, titanium oxide, niobium pentoxide, toughened fibers, tantalum pentoxide, a granulation binder and a forming binder, and specifically comprises 60 parts of the quartz sand, 8-10 parts of the calcium oxide, 6-8 parts of the magnesium oxide, 2-3 parts of the manganese oxide, 3-4 parts of the titanium oxide, 1-2 parts of the niobium pentoxide, 10-15 parts of thetoughened fibers, 1-1.5 parts of the tantalum pentoxide, 2-3 parts of the granulation binder and 0.5-0.7 part of the forming plasticizer. The refractory material with enhanced toughness is modified by adopting a toughening agent, and the modified refractory material has a good toughening effect. High fracture toughness of the refractory material is improved, and better mechanical impact resistance is achieved. Meanwhile, the mixture is treated by adopting a secondary granulation method, so that distribution of the toughened fibers, the granulation binder and the forming binder can be relatively concentrated in a small range.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a refractory material with enhanced toughness. Background technique [0002] Refractory materials are a type of inorganic non-metallic materials with a refractoriness of not less than 1580°C. Refractoriness refers to the temperature in Celsius at which a refractory conical sample can resist high temperature without softening under the condition of no load. It is now defined as any physical Materials whose chemical properties allow their use in high temperature environments are called refractory materials. [0003] The poor mechanical toughness of inorganic non-metallic materials is a common problem in inorganic non-metallic materials and materials. As refractory materials that belong to inorganic non-metallic materials, their mechanical toughness is also poor. [0004] Refractories belong to inorganic non-metals, and their mechanical toughness is also poor. Due to t...

[0003] The poor mechanical toughness of inorganic non-metallic materials is a common problem in inorganic non-metallic materials and materials. As refractory materials that belong to inorganic non-metallic materials, their mechanical toughness is also poor.

[0004] Refractories belong to inorganic non-metals, and their mechanical toughness is also poor. Due to the large temperature difference between rapid cooling and rapid heating and use, refractory materials are prone to cracking and peeling under the action of thermal expansion and contraction, which affect the integrity of refractory materials. , which reduces the service life of the refractory material. The sintering temperature of the refractory material in the prior art is high, wastes resources, and costs are high. Moreover, the refractory material is brittle, poor in toughness, poor in corrosion resistance, and has a short service life. Poor thermal shock resistance during the process, prone to cracking
