Self-flowing Castable Introduction

Self-flowing castable is mainly used to fill the gap between the water-cooled wall and the furnace skin at the throat of the blast furnace. Refractory castables are required to be self-leveling after adding water. Through technical research and development by Rongsheng, the self-flowing castables can achieve self-leveling when the amount of water used is low. can be poured into any shape without vibration, and has high strength and stable volume. Self-flowing castables are mainly divided into high alumina, mullite, and corundum according to their composition.

Key technologies for producing self-flowing castables

Self-flowing castables are developed on the basis of low cement and ultra-low cement. It is a refractory material composed of refractory aggregates, powders, and high-efficiency dispersants with a certain particle size distribution. The key to the production of self-flowing castables lies in the particle size, quantity, and rational use of high-efficiency dispersants of superfine powders. Allows the pouring material to spread automatically.

Advantages of self-flowing castables over vibration castables

  1. Without artificial vibration, it will be rolled out automatically under the action of its own weight
  2. It can reach parts that vibration castables cannot reach
  3. Pumping construction can be used to reduce labor intensity

Application of self-flowing castable

Self-flowing castables can be used in a wide range of applications, such as continuous casting tundish linings, electric furnace roof triangles, tapping holes, ladles, heating furnaces, blast furnace tapping channels, cast iron induction furnaces, boiler protection pipes, etc.
