In the core link of blast furnace smelting, refractory materials play a vital role. The following will analyze the production and application of blast furnace refractory materials and the industry contribution of Gongyi Yuying Refractory Materials Co., Ltd. from different angles.

一． The secret of the production process of hot blast furnace

The hot blast furnace is an indispensable core component in blast furnace smelting. Its main function is to heat the air to improve the smelting efficiency of the blast furnace. The following is the production process of the hot blast furnace:

1. Design customization: According to the actual needs and scale of the blast furnace, the size, structure and combustion system of the hot blast furnace are tailored.

2. Material screening: Select high temperature resistant and corrosion resistant refractory materials, such as high alumina bricks, silica bricks, etc.

3. Structural masonry: According to the design drawings, the main body of the hot blast furnace is constructed with selected materials.

4. System installation: Equipped with key facilities such as burners and hot air ducts to ensure the stable operation of the hot blast furnace.

5. Performance debugging: Comprehensively test the performance of the hot blast furnace to ensure that it meets the design standards.

二，Definition and structural analysis of blast furnace

A blast furnace is a vertical smelting furnace used for metal refining, including the furnace hearth, furnace body, furnace throat and furnace roof. The blast furnace produces metal products such as pig iron and steel through the reduction reaction of raw materials such as coke and ore at high temperature.

三，Types and applications of blast furnace refractory materials

The temperature inside the blast furnace is as high as 1500℃, so the requirements for refractory materials are extremely harsh. The following are some commonly used refractory materials:

1. High alumina bricks: high temperature resistance, corrosion resistance, and strong slag resistance.

2. Silica bricks: high temperature resistance, corrosion resistance, and good thermal conductivity.

3. Refractory mud: fill brick joints to enhance structural stability.

4. Refractory fiber: lightweight, heat-insulating, high temperature resistance, suitable for insulation layer.

Selection and application of blast furnace refractory bricks

Common refractory bricks in blast furnaces include:

1. High alumina bricks: suitable for furnace bottom, furnace hearth and other areas.

2. Silica bricks: suitable for furnace walls, furnace throats and other parts.

3. Magnesium bricks: suitable for furnace roofs and other parts.

4. Refractory slurry: used for masonry gaps.

四 Performance requirements for blast furnace refractory materials

Blast furnace refractory materials need to meet the following performance requirements:

1. High temperature resistance: adapt to the high temperature environment of more than 1500℃ inside the blast furnace.

2. Corrosion resistance: resist the corrosive gas in the blast furnace.

3. Slag resistance: cope with the erosion of slag in the blast furnace.

4. Structural stability: withstand the harsh conditions of high temperature and high pressure.

五 Types of blast furnace repair refractory materials

Commonly used refractory materials for repairing blast furnaces include:

1. Refractory slurry: repair brick joints, furnace walls, etc.

2. Refractory spray coating: repair furnace walls, furnace roofs, etc.

3. Refractory castables: repair furnace bottoms, furnace cylinders, etc.
