refractory materials

  What characteristics should blast furnace gunning material have? 1 The original furnace refractory material of blast furnace is fully utilized, and the consumption of refractory material is reduced. 2. The gunning operation time is short, the intermediate repair time is saved, and the blast furnace operation rate is improved. ) significantly reduces the heat that needs to be taken away by cooling during major and medium repairs of the blast furnace, thereby reducing energy consumption. 4) The construction of gunning operation is convenient. After gunning, it is beneficial to maintain a reasonable furnace type, improve the distribution of charge and gas flow, improve the utilization of gas energy, and play a role in increasing production and consumption. What are the main methods of blast furnace gunning and gunning materials ? Blast furnace gunning method gunning materials can generally be divided into the following three ways: (1) Ordinary cold gunning. Generally...

  What is bauxite used for? Bauxite is a kind of bauxite which is made of bauxite as raw material, sintered at 1500 ℃ to form a block, ground, bagged and processed by a crusher. The sieve fineness of bauxite is about 325 mesh. It is usually used in precision casting. Yyrefractory is a professional manufacturer of all kinds of refractory grade bauxite. 1. Aluminum industry. It is used in the fields of national defense, aviation, automobile, electrical appliance, chemical industry, daily necessities and so on. Precision casting. The bauxite clinker is processed into fine powder and made into a precision casting mold. Suitable for military, aerospace, communications, instrumentation, machinery and medical equipment and other sectors. 3. Refractory products. The refractoriness of bauxite clinker is as high as 1780℃, with strong chemical stability and good physical properties. 4. Aluminum silicate refractory fiber. It has the advantages of light weight, high temperature...

  What is refractory ? Refractory refers to the temperature in degrees Celsius at which a conical specimen of refractory material can withstand the action of high temperatures without softening and melting under no load. However, refractories cannot be completely described by the definition of refractoriness, and 1580°C is not absolute. Yyrefractory refractory raw materials are a class of inorganic non-metallic materials whose refractoriness is not lower than 1580℃. Materials now defined whose physical and chemical properties allow their use in high temperature environments are called refractories. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, electric power and other industrial fields. They are used the most in the metallurgical industry, accounting for 50%-60% of total production. The workability of refractory materials includes consistency, slump, fluidity, plasticity, cohesion, resilience, co...
