Refractory Alumina Magnesia Carbon Bricks 1000 C Fire Clay Bricks 25MPa

Carbon brick heat insulation Refractory Materials Iron and steel smelting

Product introduction

Refractory bricks are called refractory bricks. Refractory fired from refractory clay or other refractory materials. Light yellow or brown. It is mainly used in building smelting furnace and can withstand high temperature of 1580 ℃ - 1770 ℃. Also called refractory brick. Refractory of certain shape and size. According to the preparation process, it can be divided into sintered brick, non sintered brick, fused cast brick (fused cast brick) and refractory and heat insulation brick; It can be divided into standard brick, ordinary brick, special-shaped brick, etc. according to shape and size. It can be used as the structural material of high-temperature building materials, building kilns and various thermal equipment. It can withstand various physical and chemical changes and mechanical effects at high temperature. Such as refractory clay brick, high alumina brick, silica brick, magnesia brick, etc.

Its properties

Carbon brick has good thermal stability, small coefficient of thermal expansion, high temperature resistance, resistance to the erosion of various acids, alkali, salt and organic solvents, but easy to oxidize in an oxidizing atmosphere.
Carbon brick is dark gray, shiny, burned into a good carbon brick does not stain the hand, with a small hammer knock clear sound. High refractoriness and load softening temperature, good thermal shock resistance; It is not wet by molten slag and molten iron, and almost not corroded by all acid, alkali, salt and organic drugs. It has good slag resistance, stable volume at high temperature, high mechanical strength, good wear resistance, and good electrical and thermal conductivity.
In addition, carbon is easy to oxidize, whether the raw material calcination or product roasting and the use of products, must be carried out in the reducing atmosphere.

Carbon brick

Carbon brick by coke, anthracite or graphite and tar as raw materials, after mixing, forming, in the reduction flame burned to 1450℃ and become a carbon refractory material. The mass fraction of carbon is 88%-90%. Can withstand the erosion of molten metal and slag, but easy to oxidize. Used for laying bottom and belly of blast furnace.

Company profile

Henan Geng Hong Industry Co., Ltd. (hereinafter referred to as "Geng Hong industry") was founded in 2007, specializing in the production, manufacturing and sales of complete sets of iron and steel metallurgical equipment, spare parts of metallurgical equipment and metallurgical accessories. At the same time, it cooperates with domestic metallurgical design institutes and European abax group to undertake the engineering design and contracting construction of complete sets of continuous casting and rolling production lines overseas. Over the years, Geng Hong industry has gradually developed into a comprehensive enterprise integrating design, production, sales and service with the core task of meeting customer needs.

Since its establishment, adhering to the principle of "customer as the core, quality as the foundation and service-oriented", Geng Hong industry has successively established and invested in three factories in Anhui, Luoyang and Nanyang, China. Focusing on the needs of iron and steel enterprises, Geng Hong industry has formed a production and sales system of complete sets of metallurgical equipment, equipment spare parts and metallurgical auxiliary materials, It has also obtained the full overseas sales right of refractory products of cooperative factories, and has set up branches or offices in Hong Kong, Taiwan, Vietnam, Malaysia and Iran. After more than ten years of development, the company has a turnover of more than 30 million US dollars in 2020. Its customers involve major domestic steel mills and more than 20 foreign customers. At the same time, the company provides excellent technical services and support of other trade products for foreign customers.

With the continuous development of the enterprise, we strive to explore a wider international market, pursue to provide customers with more excellent quality, efficient product performance and high-quality service, and become an excellent partner of customers。
