硫黄焼却炉にはどのような耐火物が使用されていますか?

硫黄焼却炉は、化学分野で一般的な高温装置の 1 つです。, 冶金学的な, その他の産業分野, 主に硫化物の焼却と酸化に使用されます。. Due to its high temperature and strong corrosive working environment, it has extremely high requirements for refractory materials. Selecting suitable refractory materials is crucial for the efficient operation and long life of sulfur incinerators. 高アルミナレンガ, シリカレンガ, ムライトレンガ, zirconium refractory materials, and various insulation materials are all indispensable key materials in sulfur incinerators. The following is an introduction to the refractory materials commonly used in sulfur incinerators.

Introduction to refractory materials commonly used in sulfur incinerators

コランダムブリック: Corundum brick is a high-temperature refractory material composed of alumina and corundum (the main crystal phase in alumina). Corundum brick is widely used in various industrial applications due to its good high-temperature resistance, 耐摩耗性, 化学的安定性.

Corundum-mullite brick: It combines two crystal phases, corundum and mullite. Corundum-mullite brick usually contains alumina, コランダム, and mullite in its composition. The combination of the two makes the brick have some good properties and is widely used in high-temperature industrial fields, especially when high-temperature stability, 耐摩耗性, and chemical stability need to be considered at the same time.

耐火物キャスタブル: This is a castable refractory material, usually used for the bottom of sulfur furnaces and other parts with complex shapes. キャスタブル are more flexible than refractory bricks, are easier to adapt to different shapes, and are easy to construct.

Refractory coating: This is a coating used to cover the surface of the furnace to provide additional fire resistance. It can be applied to the surface of refractory bricks or other refractory materials to improve their corrosion resistance.

Refractory ceramic fiber products: Ceramic fiber products are used for heat preservation and filling cracks and pores in furnace bodies. This material is light and has good thermal insulation properties.

Corrosion-resistant coating: Corrosive gases may be produced during the incineration of sulfur ore, and corrosion-resistant coating can help protect the furnace body from corrosion.

High-temperature resistant mastic: Used to fix and connect refractory materials to ensure they maintain structural integrity in high-temperature environments.
