Magnesia-chrome brick is a kind of high performance refractory material, which is widely used in high temperature industry. It is favored for its excellent high temperature performance, chemical corrosion resistance and long service life. This paper will introduce the characteristics, uses, quality control and related services of magnesia-chrome brick in detail to help readers fully understand this important material.

I. Characteristics of magnesia-chrome brick

Magnesia-chrome brick is made of high-purity or sub-high-purity sintered or melted magnesia and chrome ore concentrate as raw materials. In the production process, high-purity sintered magnesia and chrome ore are used, and the silicon dioxide content is less than 2%, which is sintered at high temperature. The glass phase of this brick is concentrated in the triangular area of the crystal phase, and the crystal phase is directly combined, which makes the product have the following remarkable characteristics:

(1) High structural strength at high temperature

Magnesia-chrome brick can maintain a stable structure in high temperature environment and is not easy to be deformed or damaged. This makes it able to bear huge heat load in high temperature furnaces and ensure the normal operation of furnaces and kilns.

(2) High load softening temperature

The load softening temperature of magnesia-chrome brick is high, which means that it can still maintain good performance under high temperature and high load conditions. This feature makes it suitable for industrial equipment that needs long-term high-temperature operation, such as cement rotary kiln and glass melting furnace.

(3) Strong chemical erosion resistance

Magnesia-chrome brick has strong resistance to chemical corrosion. It can effectively resist the corrosion of various chemical media in the furnace, prolong the service life of the furnace lining and reduce the maintenance cost.

II. Use of magnesia-chrome brick

Magnesia-chrome brick has been widely used in many industrial fields because of its excellent properties. The following are its main uses:

(1) Cement rotary kiln

Cement rotary kiln is the key equipment in cement production, with high working temperature and harsh environment. Magnesia-chrome brick can withstand high temperature and chemical erosion, and is an ideal material for cement rotary kiln firing zone.

(2) Glass melting furnace

Glass melting furnace needs to run at high temperature for a long time, and the requirements for refractories are extremely high. The high temperature performance and corrosion resistance of magnesia-chrome brick make it an ideal choice for glass melting furnace.

(3) Electric steelmaking furnace

The steelmaking electric furnace will produce high temperature and strong chemical reaction during steelmaking. Magnesia-chrome brick can withstand these extreme conditions, protect furnace lining and improve production efficiency.

(4) Converter

Converter is an important equipment in steelmaking process, which requires refractories with good corrosion resistance and high temperature performance. Magnesia-chrome brick can meet these requirements and prolong the service life of converter.

(5) Non-ferrous metal smelting furnace

There will be a lot of chemical erosion in the process of nonferrous metal smelting, which requires extremely high performance of refractories. Magnesia-chrome brick has become an ideal material for nonferrous metal smelting furnace because of its excellent corrosion resistance.

III. Quality control of magnesia-chrome brick

Quality is the lifeline of products, especially for magnesia-chrome brick, a high-performance refractory. Zibo Zhuoyue Refractory Co., Ltd. has a perfect quality control system to ensure that every magnesia-chrome brick meets high quality requirements.
