Problems solved by technology

In the past, iron and steel enterprises basically used boric acid, phosphate fertilizer, combustion improver, and sintering agent in the sintering process. These additive products were either single-effect or compound crude and low-efficiency, which directly affected the comprehensive benefits of ironmaking.

Abstract

The invention relates to an additive in the process of smelting iron and steel, which comprises the following parts: 10%-15% sodium peroxide, 15%-25% sodium per chlorate, 5%-10% calcium chloride, 20%-28% borax, 5%-15% calcium nitrite, 5%-8% sodium methylol fibre, 5%-8% sodium perborate, 10%-20% polyacrylamide. The manufacturing technique comprises the following steps: (1) adding every part sequentially according to the weight and mixing mechanically; (2) mixing and heating; (3) filtering; drying and finishing the product. The invention improves the insufficient places of the original additive product, which develops a new additive; reduces the cost of smelting iron; adds the benefit.

Description

technical field [0001] The present invention relates to an additive in iron and steel smelting process. Background technique [0002] The development of ironmaking industry focuses on energy saving, efficiency enhancement and environmental protection. Sintering is an important part of the ironmaking process. In the past, iron and steel enterprises basically used boric acid, phosphate fertilizer, combustion accelerant, and sintering agent in the sintering process. These additive products are either single-effect or complex and inefficient, which directly affects the comprehensive benefits of ironmaking. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a new type of iron and steel smelting additive and its processing technology, which have the characteristics of improving the quality of sintered ore and reducing the production cost of ironmaking. [0004] For achieving the above object, the present invention adopts following technical sc...
