Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of refractory material pouring, in particular to a refractory material pouring device and a using method thereof. BACKGROUND

[0002] In the process of manufacturing refractory products, the refractory material is usually poured into a mold through a pouring device, and the desired product is obtained after cooling and shaping. Before shaping, the refractory castable needs to be fully stirred to ensure good performance. Therefore, a stirring mechanism is often provided in the existing pouring device for stirring operation, such as the existing patent (application number CN202023268983.7) a refractory material pouring device.

[0003] However, the stirring position of the stirring mechanism in the above pouring device is fixed, which limits the stirring range and further reduces the overall stirring effect of the pouring device. In addition, to improve the physical and chemical properties and construction performance of the refractory castable, an appropriate amount of additive such as plasticizer and dispersant is often added during stirring. The addition of additives is usually done manually, which is time-consuming and labor-intensive. In addition, the addition position of the additive is generally fixed, which makes the additive not well dispersed and reacted with the refractory material. In the pouring process, the pouring amount in the mold is usually controlled manually, which has certain errors and sometimes results in over-pouring or under-pouring.

[0004] Therefore, we propose a refractory material pouring device and a using method thereof to solve the above problems. SUMMARY
