Description

Technical Field

[0001] The utility model belongs to the technical field of magnesia-chrome bricks, and in particular relates to a composite magnesia-chrome brick. Background Art

[0002] Magnesia-chrome bricks are refractory products with magnesium oxide and chromium trioxide as the main components, and periclase and spinel as the main mineral components. This type of brick has high refractoriness, high high temperature strength, strong resistance to alkaline slag erosion, excellent thermal stability, and a certain adaptability to acidic slag. The main raw materials for making magnesia-chrome bricks are sintered magnesia and chromite. The purity of the magnesia raw material should be as high as possible. The loosening effect caused by the expansion of iron oxides when they react to form spinel can also be made into magnesia-chrome bricks using synthetic co-sintering materials. In addition, there are unfired magnesia-chrome bricks, for example, unfired magnesia-chrome bricks combined with inorganic magnesium salt solutions. The production process of unfired magnesia-chrome bricks is simple, the cost is low, and the thermal stability is good, but the high temperature strength is far less than that of fired bricks. In the late 1950s, a so-called "directly bonded" magnesia-chrome brick was developed. The characteristics of this brick are pure raw materials, high firing temperature, direct bonding between high temperature phases such as periclase and spinel, and island-like distribution of low melting phases such as silicates, thus significantly improving the high temperature strength and slag resistance of the bricks.

[0003] Application No. 202220905359.3 provides a composite magnesia-chrome brick, in which a thermal insulation layer is fixedly connected to the surface of the magnesia-chrome brick body, a protective layer is fixedly connected to the outside of the thermal insulation layer, and limit slots are provided on both sides of the inside of the magnesia-chrome brick body, and the bottom of the protective layer is clamped on the left and right sides of the limit slots. The protective layer, the thermal insulation layer, and the magnesia-chrome brick body are pressed and formed at one time, and the connection strength is high and the stability is good, thereby achieving the beneficial effects of improving the thermal insulation performance of the magnesia-chrome brick body, reducing the friction of the cement of the magnesia-chrome brick body, protecting the magnesia-chrome brick body, and extending the service life of the magnesia-chrome brick body; two groups of fixed blocks are fixedly connected to the left side of the protective layer, and two groups of fixed slots are provided on the right side of the protective layer. When the left and right brick bodies are connected, the fixed blocks are clamped into the fixed slots to fix them, thereby achieving the enhancement of the connection strength between the brick bodies; a plurality of groups of enhanced shrinkage through holes are provided inside the magnesia-chrome brick body to provide space for the thermal expansion of the magnesia-chrome brick body, thereby achieving the improvement of the expansion coefficient of the magnesia-chrome brick body;

[0004] However, when the magnesia-chrome brick is assembled, since the side wall of the magnesia-chrome brick is installed with a fixed block, the fixed block protrudes from the side wall of the magnesia-chrome brick. As a result, when the magnesia-chrome brick is installed on the edge, the protruding fixed block affects the installation of the magnesia-chrome brick, resulting in the magnesia-chrome brick that needs to be attached to the wall being difficult to place due to the existence of the fixed block, and the practicality is poor.
