Abstract

The invention relates to a preparation process of a slag pot isolator, belonging to the technical field of smelting. The preparation process comprises the following steps: (1) adding 65-75 percent of regenerated scrap grains and 25-35 percent of alumina cement into mixing agitation equipment; (2) additionally adding 0.01-0.03 percent of water reducing agent, 0.1-0.5 percent of additive and 12-15 percent of liquid wedding agents into the mixing agitation equipment; (3) smelting the materials for 5-8 minutes in a mixing way under the condition that the outdoor temperature is 5 DEG C-25 DEG C; (4) vibrating the smelted mixing materials to be flat by a vibrating spear; (5) shaping products by self fixing so that the products can be demolded; (6) naturally maintaining; (7) roasting and selecting the products to obtain products which accord with the strength requirement to prevent the products from being burst; and (8) checking the roasted products to obtain the slag pot isolator according to a physicochemical index specification value and an outline dimension standard corresponding the products. With the preparation process of the slag pot isolator, waste bricks are recovered to be circularly mixed into the preparation materials, and the technical index and the property of the prepared slag pot isolator is the same as that of a slag pot isolator prepared by fresh materials, thereby the invention achieves good popularization and application effect.

Description

technical field [0001] The invention relates to a material preparation process in the technical field of smelting, in particular to a preparation process for a slag tank separator. Background technique [0002] With the development of society and the enhancement of people's awareness of environmental protection, the use of slag tank separators in steelmaking plants will become more and more common. By using the slag tank isolator, the cost of re-cutting and round-trip transportation is reduced, and the production cost is greatly reduced; the environmental pollution caused by cutting is eliminated, and it has been well received by steel mills. At present, there are many steel mills in Shanghai, and the market prospect is broad. . [0003] At the end of steelmaking, during the process of pouring steel slag from the ladle to the slag ladle, a part of molten steel is often brought out. After the molten steel cools, it forms an integral body with the steel slag, which will bring...
