Description

Pressing die for producing annular convex-concave groove refractory product

Technical Field

The utility model relates to a shaping refractory product field, in particular to embossing mold utensil for producing annular tongue and groove refractory product.

Background

The refractory products are classified into standard type, common type, special type and special type, wherein the special type and special type refractory products are difficult to produce due to special appearance size and shape. The standard type and the common type both belong to cuboids, most of the shapes are wedge-shaped bricks and straight bricks, the design of a mold used for producing the brick is easy, and the product is widely applied.

The special-shaped and special-shaped products are widely applied to high-temperature kiln thermal equipment such as glass kilns, rotary kilns, hot blast furnaces, blast furnaces and the like, play a key role in a special building part and play an important role in supporting the kiln body structure of the whole kiln, so that the special-shaped and special-shaped products are concerned by people and are typically represented by annular convex-concave fireproof products.

These annular convex-concave refractory special-shaped products are usually formed by pouring and vibration molding, that is, the prefabricated member is often called, although vibration pouring molding can meet most of the requirements of kiln design and use, the prefabricated member has its weaknesses, such as: 1. the production process of the castable is complex and tedious and needs long-time maintenance. 2. The water adding amount is more, and the high-temperature use advantage of the product is reduced. 3. The labor intensity of demoulding the mould is relatively high, and the like. For large prefabricated parts, besides casting molding, for special kiln parts such as tundish small prefabricated parts, the service life of the shaped products is obviously longer than that of the cast products, and the shaped products have more obvious use advantages, high-temperature strength, extremely low water content, corrosion resistance and higher molten steel heat flushing resistance.

Meanwhile, for the special-shaped and special-shaped products of the type, although the local special-shaped structure can be processed by the production mode of a numerical control machine tool, the process has no obvious advantages in terms of cost and production efficiency, and therefore, a production mold of the refractory shaped product with the annular convex-concave groove is required to be developed.

At present, the main technical difficulty of the brick press for producing the special-shaped products of the annular convex-concave grooves is the difficulty of a brick discharging system of a mould, and the normal brick discharging of the mould cannot be ensured by the conventional mould design, so that the technical development of the shaped products is limited. In the existing open mold design field, although normal brick discharging of the mold can be ensured, the brick discharging system is complex in design, and the later-stage mold and equipment maintenance cost is high, so that the improvement is still to be carried out.
