Problems solved by technology

However, in my country's proven coal resources, the main coking coal and other coal types suitable for coking account for less than 30%, and most of them are distributed in Shanxi and Shaanxi. , leading to high coke prices, which is not conducive to the development of steel and other smelting industries that have a large demand for coke. Therefore, research on new materials to replace coke for smelting production has become a key research topic in steel, alloy and other smelting industries

Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing.

[0015] Such as figure 1 As shown, a kind of exclusive filler for metal smelting is characterized in that: the exclusive filler is mixed and shaped by coal powder and metal ore powder, and is obtained by anaerobic pyrolysis to remove moisture and volatile matter. It is made of carbon fixation, The molding material composed of ash and metal ore powder.

[0016] The porosity of the exclusive filler is ≥45%, and has good reactivity.

[0017] The exclusive filler has a stable structure, good compression resistance, and can withstand a weight of more than 100kg.

[0018] The shape of the exclusive filler can be adjusted according to the needs of back-end customers.

[0019] Working principle: The metal ore powder is mixed and formed with coal powder in proportion, and the formed mixture is subjected to anaerobic pyrolysis to remove the moisture and volatile matter in the coal ...

Abstract

The invention relates to a special filler applied to metal smelting. The filler is prepared by mixing and molding pulverized coal and metal mineral powder and removing moisture and volatile components through anaerobic pyrolysis, is a molded material consisting of fixed carbon, ash and metal mineral powder, can be used for smelting coke in a traditional smelting process, and plays a role of a strong reducing agent and a skeleton support.

Description

technical field [0001] The invention belongs to the field of metal smelting, and in particular relates to a special filler used in metal smelting. Background technique [0002] In the traditional smelting industry, coke is usually used as the skeleton support and reducing agent in the smelting process. However, in my country's proven coal resources, the main coking coal and other coal types suitable for coking account for less than 30%, and most of them are distributed in Shanxi and Shaanxi. , resulting in high coke prices, which is not conducive to the development of steel and other smelting industries that have a large demand for coke. Therefore, research on new materials to replace coke for smelting production has become a key research topic in steel, alloy and other smelting industries. [0003] The invention proposes a new type of exclusive filler in the smelting process, which can replace coke for smelting, and can strongly support the long-term development of smelting...
