Technical Field
The utility model relates to a ladle smelting technical field, in particular to a monolithic furnace lining for ladle edge district.
Background
The refractory plastic material is an unshaped refractory material which is prepared by adding water (or liquid containing a binding agent) into refractory aggregate, powder, a binding agent and an additive with a certain grain composition, mixing and extruding the refractory aggregate, the powder, the binding agent and the additive into a blocky or muddy material, still has good plasticity after being packaged and stored for a certain time, and can be constructed by a ramming method. The water content of the plastic material is less, and the plastic material can be hardened after being exposed in the air for a short time, so that the joint surface needs to be continuously constructed during construction. When plastic is used at the position of the furnace top, the furnace top adopts a hanging structure, and refractory materials are hung to form a whole through the anchoring bricks, so that the plastic and the anchoring bricks are required to be tightly combined.
The anchoring bricks are hung on a steel structure of the furnace top, and each anchoring brick must be prestressed in the construction process, so that the stress surface of the furnace top is uniform and does not slump. The plastic material inevitably expands to the periphery in the process of being combined by external force, and the thickness of the furnace top cannot be ensured. And the ladle edge area can only be constructed manually by using plastic materials, the manual construction operation time is long, the working strength is high, and the danger coefficient is high. In addition, the plastic material can generate strength only through the baking process, which phase-change prolongs the construction time of the furnace top and delays the production.
Therefore, the integral furnace lining capable of effectively improving the installation performance of the furnace lining of the ladle edge zone needs to be researched.
