Embodiment Construction

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention discloses a casting heat preservation method and heat preservation device. The casting heat preservation method comprises the following steps: setting a heat preservation body, the top surface of the heat preservation body is provided with an installation groove; placing a refractory body in the installation groove, and the thermal conductivity of the refractory body is greater than The thermal conductivity of the heat preservation body; the cast workpiece is placed on the heat preservation body, and the middle part of the bottom surface of the workpiece is opposite to the refractory body; a box surrounding the heat preservation body and the workpiece is set, and a medium is filled in the box, and the medium is heat preservation material. In the above heat preservation method for castings, the thermal conductivity of the refractory body is greater than that of the heat preservation body. Compared with the outer edge part of the bottom surface of the workpiece, the middle part of the bottom surface of the workpiece can conduct heat more quickly, but the outer edge part of the bottom surface of the workpiece can also pass through several parts of the workpiece. If the two sides conduct heat conduction and dissipate heat, the temperature difference between the middle part of the bottom surface of the workpiece and other parts will not be too large, which can better prevent cracks and other defects of the workpiece due to the large temperature difference.

Description

technical field [0001] The invention relates to the technical field of refractory material processing, in particular to a casting insulation method and insulation device. Background technique [0002] Refractory bricks have strong high temperature resistance and can be used in high temperature environments such as furnaces and kilns. Among them, the corundum brick is made by casting, and the temperature of the corundum brick needs to be cooled after casting. However, in the traditional process, the corundum brick is prone to defects such as cracks on the bottom surface during cooling, resulting in a decline in the yield of the product. Contents of the invention [0003] Based on this, the present invention overcomes the defects of the prior art, and provides a casting insulation method and insulation device that can prevent cracks. [0004] Its technical scheme is as follows: [0005] A casting insulation method, comprising the following steps: [0006] A thermal insula...
