Problems solved by technology

As a result, it takes a long time to remove slag. During the process of removing slag, a large amount of molten iron is lost along with the slag, and the loss of molten iron is serious, which directly affects the output and consumption indicators of steel materials.

Abstract

The invention relates to a method for preparing a slag conglomeration agent for molten iron steel, in particular to a method for preparing a slag conglomeration agent for iron steel. The method comprises the following steps: (1) crushing 15 to 20 percent by weight of albite, 20 to 25 percent by weight of fluorite, 10 to 15 percent by weight of raw vermiculite, 10 to 15 percent by weight of calcium carbonate and 20 to 30 percent by weight of waste glass; (2) pulverizing with the particle size of 0.1 to 3.0 mm; (3) batching, that is, mixing the materials; (4) milling, wherein 1 to 5 percent of common salt is added for milling, the milling temperature is 20 to 30 DEG C, and the milling time is 10 to 30 min; and (5) detecting and packaging. Through the adoption of the slag conglomeration agent for iron steel, which is prepared according to the method, easy slag collection and slag discharge are realized, deslagging iron loss is reduced fundamentally, and the basicity and the melting temperature of furnace slag are reduced so as to improve the fluidity of desulphurized iron slag.

Description

technical field [0001] The invention relates to a preparation method of a molten iron and steel slag accumulator. Background technique [0002] With the rapid development of the domestic economy and society, my country has become the largest producer of steel in the world. The rapid growth of market demand for high-quality steel products has led to the continuous and rapid development of the domestic steel industry in the past ten years. The scale of steel manufacturing enterprises has continued to expand, and a series of new metallurgical technologies and processes have been widely promoted and applied. But on the whole, compared with some steel powers in the world, my country's steel industry is relatively backward in production technology, equipment and technical level, which makes domestic steel products compared with foreign advanced steel manufacturing countries in terms of product structure, performance and variety. , There is a certain gap. On the one hand, the produ...
