Description

Technical Field

[0001] The utility model belongs to the technical field of industrial casting, and particularly relates to a casting material anti-falling device. Background Art

[0002] Anchor castables for castables are also called refractory castables. They refer to a mixture of refractory aggregates, binders and admixtures, which are mixed with water (or liquid binder) to form a mud material that can be constructed by pouring. Refractory castables have a certain setting and hardening time after construction. Therefore, after casting, they need to be cured for a certain period of time before they can be demoulded. After that, they can be put into baking for use after an appropriate period of natural curing. They are usually used to construct industrial furnace linings. In order to improve the strength and service life of the castable, anchors are usually embedded in the castable. Currently, the anchors commonly used generally have V-type, Y-type, U-type and other structures. The bottom of the anchor is welded and fixed to the steel shell. After the castable is cast and formed, the anchor structure is embedded in the castable to connect and fix the steel shell and the castable. Since the anchor and the steel shell are often in point contact, it is not easy to pre-position during welding, and the strength is also low during use, and the anchoring effect is poor.
