Abstract
The utility model discloses a ladle work lining which is composed of a magnesium carbon brick structure (1) and a pouring material structure (2). The magnesium carbon brick structure is built in the inner side of the ladle dreg line part, the pouring material structure (2) distributes on a melting compartment and a ladle bottom. The ladle work lining has advantages of low cost, long service life and can satisfy smelting requirement.
Description
Technical field
The utility model belongs to technical field of ferrous metallurgy, relates to a kind of ladle working lining.
Background technology
The tradition ladle working is lined with two kinds of masonry constructions.
A kind of for watering the material feeding structure entirely: this structure all adopts ladle slag line, molten bath and position, bag bottom and waters the material feeding cast.This kind structure fabrication cost is little, but service life is short.Because smelting the steel grade product increases, the external refining time increases, slag lining is influenced by the physics infiltration and the chemical erosion of high temperature slag for a long time, cause the refractory corrosion degree at this position to be ahead of other position, and form deep chase, can not corrode synchronously with the anti-material of Bao Bi and position, bag bottom, have to remove, cause the waste of refractory material.
Another kind is the masonry construction of full magnesia carbon brick: this structure is to ladle slag line, and the molten bath and the bag end all adopt magnesia carbon brick to build by laying bricks or stones.This kind structure erosion resisting is good, long service life, but cost of manufacture is higher, has increased the phosphorus content in the molten steel simultaneously, incompatibility ultra-low-carbon steel, the smelting demand of steel grades such as clean steel.
Summary of the invention
The purpose of this utility model is to provide a kind of and overcomes above-mentioned shortcoming, cost is low, the life-span is long and can satisfy the ladle working lining of smelting demand simultaneously.
The utility model is achieved in that a kind of ladle working lining, and by the magnesia carbon brick structure and water material feeding structure two parts and constitute, the magnesia carbon brick structure is built by laying bricks or stones in the inboard at ladle slag line position, waters the material feeding structure distribution in molten bath and position, bag bottom.
The utility model combines the advantage of two kinds of structures of prior art, molten steel is corroded serious slag lining, the employing magnesia carbon brick is built by laying bricks or stones, adopt aluminum-spinel matter to water the material feeding cast to corroding position, lighter molten bath and bag bottom, can satisfy the demand that iron and steel enterprise smelts high-quality steel, whole ladle is corroded synchronously, and bag significantly improves age, and the full magnesia carbon brick of cost build by laying bricks or stones low.
Description of drawings
Accompanying drawing is a sectional structure schematic diagram of the present utility model.
Among the figure: 1, magnesia carbon brick structure, 2, water the material feeding structure.
The specific embodiment
As shown in the figure, the utility model comprises magnesia carbon brick structure 1 and waters 2 two kinds of structures of material feeding structure.Molten steel is corroded serious slag lining, adopt magnesia carbon brick to build by laying bricks or stones, adopt aluminum-spinel matter to water the material feeding cast corroding position, lighter molten bath and bag bottom.The utility model has fully utilized the advantage of different structure, has both effectively saved cost, and whole ladle is corroded synchronously, and the bag life-span in age significantly improves, and has satisfied the demand that iron and steel enterprise smelts high-quality steel simultaneously preferably.
Claims (1)
1, a kind of ladle working lining is characterized in that: by magnesia carbon brick structure (1) and water material feeding structure (2) two parts and constitute, magnesia carbon brick structure (1) is built by laying bricks or stones in the inboard at ladle slag line position, waters material feeding structure (2) and is distributed in bottom molten bath and the bag.
