Manufacturing process of light heat insulation refractory castable

Abstract

The invention discloses a manufacturing process of a light heat insulation refractory castable. The manufacturing process comprises the following steps: S1, crushing treatment, namely putting large-block raw materials into a jaw crusher for crushing, and simultaneously carrying out medium crushing and fine crushing on the crushed raw materials, wherein the equipment comprises a cone crusher, a roller crusher and a dry grinding machine, and is used to obtain the powdery refractory raw materials through breaking and crushing treatment; S2, screening treatment, namely putting the crushed refractory raw materials into a screening device, screening the crushed refractory raw materials by the screening device, and dividing the refractory raw materials into granular raw materials with different particle sizes according to particle sizes, wherein the screening device is divided into a fixed inclined screen device and an electromagnetic vibrating screen and is used to prepare the granular refractory raw materials, and S3, fine grinding, namely putting the screened granular raw materials into a grinding device, grinding the granular raw materials by the grinding device, wherein the grindingdevice is divided into a ball mill, a tube mill and a vibration mill. The manufacturing process has the beneficial effects of ensuring the cleanness of the inside of a mixer and recycling the residualraw materials in the mixer.

Description

technical field

[0001] The invention relates to the field of castables, in particular to a manufacturing process of lightweight heat-insulating refractory castables. Background technique

[0002] Castable, also known as refractory castable, is a granular and powdery material made of refractory materials with a certain amount of binder. It has high fluidity and is formed by pouring. In contrast, the binder and moisture content are higher, and the fluidity is better, so the castable has a wider range of applications. The material and binder used can be selected according to the conditions of use. It can be directly poured into a lining, and can be poured or The vibration method is used to make prefabricated blocks.

[0003] However, the internal cleaning of the mixer during the production process of the existing castables is insufficient, which is likely to affect the next mixing, and the remaining materials cannot be recycled during the production of the castables, which eas...
