Problems solved by technology

Among the metal chillers commonly used at present, the most commonly used chills are ordinary cast iron chills (such as gray iron chills, ductile iron chills, etc.), graphite chills and composite chills (a layer of graphite chills plus a Layers of cast iron and chilled iron are superimposed), although various chilled irons play an important role in improving the effect of the riser and preventing shrinkage and porosity of the casting, ensuring the quality of the casting, but their cost is relatively high

Embodiment Construction

[0008] The invention provides the application of refractory bricks in the field of casting, especially the application of refractory bricks in cooling in the field of casting.

[0009] Refractory brick is a refractory material with a certain shape and size made of refractory clay or other refractory raw materials. It is light yellow or brownish in color. It is mainly used for building smelting furnaces and can be used as building kilns and various thermal equipment High-temperature building materials and structural materials can withstand high temperatures of 1580-1770°C, so they are also called fire bricks.

[0010] The refractory bricks used in the present invention are all kinds of refractory bricks commonly used in the present. There are many types of raw materials, and the composition is mainly divided into six categories: soil, stone, sand, ore, powder and others: specifically, one of the raw materials— - Soil: it can be alumina, kaolin, clay, diatomaceous earth; the sec...

Abstract

The invention relates to an application of a refractory brick in the casting field. The application of the refractory brick in the casting field provided by the invention has the advantages of low cost, long service life, obvious cooling effect and the like.

Description

technical field [0001] The invention belongs to the field of metallurgical casting and relates to the application of a refractory brick in the field of casting. Background technique [0002] In the field of casting, in order to increase the local cooling rate of castings, it is necessary to place metal chillers on the surface of sand molds, sand cores or in the cavity for cooling. The most commonly used chills in the commonly used metal chillers are ordinary cast iron chills (such as gray iron chills, ductile iron chills, etc.), graphite chills and composite chills (a layer of graphite chills plus a Layers of cast iron and chilled iron are superimposed), although various chilled irons play an important role in improving the effect of the riser and preventing shrinkage and porosity of the casting, ensuring the quality of the casting, but their cost is relatively high. Contents of the invention [0003] In order to solve the above-mentioned technical problems in the backgro...
