Product Description

Refractory Carbon Brick Product Description

Carbon brick is a high temperature resistant neutral refractory product made of carbonaceous material as raw material and adding appropriate amount of binder. Carbon brick raw materials include anthracite, coke and graphite, as well as pitch, tar and anthracene oil binders. Anthracite has less volatile matter and dense structure. When producing carbon bricks, it is mostly used as aggregate, metallurgical coke is added, and asphalt is used as binder.

The technical requirements of carbon bricks are generally carbon content ≥92%; mechanical strength ≥25MPa; ash content ≤8%. The external dimensions are strictly required, and general products must undergo certain mechanical processing.

Properties of carbon bricks

Carbon bricks have good thermal stability, small thermal expansion coefficient, high temperature resistance, and resistance to erosion by various acids, alkalis, salts and organic solvents, but they are easily oxidized in an oxidizing atmosphere.

The carbon bricks are dark gray and shiny, and the well-fired carbon bricks do not stain the hands, and there is a crisp sound when struck with a small hammer. High refractoriness and load softening temperature, good thermal shock resistance; not wetted by molten slag, molten iron, etc., almost not corroded by all acids and alkali salts and organic chemicals, good slag resistance, stable volume at high temperature, high mechanical strength, Good wear resistance, good electrical and thermal conductivity.

In addition, carbon is easy to be oxidized, whether it is the calcination of raw materials or the calcination of products and the use of products, it must be carried out in a reducing atmosphere.

Carbon brick properties

The production process of carbon bricks is roughly similar to other refractory bricks, but carbon must be prevented from oxidizing at high temperatures, so the firing of raw materials and the firing of products must be carried out in a reducing atmosphere. Anthracite should be roasted before use to remove volatiles, sulfur and moisture, and to improve the volume stability, mechanical strength and oxidation resistance of anthracite. The coke should be dried first to avoid forming difficulties and cracking of the products during the firing process due to high moisture content. The asphalt should be melted and dehydrated first, so that its moisture content is less than 0.2%, and the dehydration temperature should be 120~160ºC.

The carbon brick ingredients are calcined granular anthracite as the aggregate, and its particle size depends on the size of the product: 8~12 mm for large bricks and 4~6 mm for small bricks. Anthracite is added at about 60%. The coke is added as fine powder, and the content of which the particle size is less than 88 microns should reach about 70%. The amount of binder added to blast furnace carbon bricks is usually 15-20%. In order to prevent oxidation, coke powder or coal powder is generally used as a protective filler when the brick body is fired. The firing temperature is 1300~1450ºC, the holding time is about 20 hours, and the total firing time is about 240~420 hours. Carbon bricks come out of the kiln at high temperature and are easy to catch fire.

Product Application

Anti Corrosion Carbon Brick are mainly used in

Carbon Bricks are widely used in the metallurgical industry. Of which carbon bricks are more used in the blast furnace. Many blast furnaces' furnace bottom and hearth are built with carbon bricks. Carbon Bricks uses, Rongsheng Carbon Bricks supplier. Carbon Bricks also can be used for pickling bath, plating bath in the electroplating industry, for the dissolving tank in the paper manufacturing industry, for the reactive tank and storage tank in the chemical industry, and for the autoclave in the petrochemical industry.
