Problems solved by technology

For example, the invention patent application with application number 200810072929.X discloses a process of pressing cast iron shavings into blocks. Water glass glue is used in this process. Because water glass glue will produce chemical pollutants at high temperatures, it will be harmful to the environment. Cause chemical pollution; and the process must use a cupola for smelting, the cupola will consume a lot of energy and increase the cost of smelting

Embodiment approach 1

[0010] Metal powder block technology for steelmaking is to mix steel slag, Portland cement and water, wherein the weight of Portland cement is 10% of the weight of steel slag, and the weight of water is 7% of the total weight of steel slag and Portland cement. %, after mixing the mixed material with a mixer, put it into a mold and compact it into a block with a size of 8×8×8cm. After 48 hours of natural curing, the strength of the block is 5.6MP.

Embodiment approach 2

[0012] The metal powder block technology for steelmaking is to mix the mixture of steel slag, steel mill powder, grinder powder, Portland cement and water, wherein the weight of Portland cement is 15% of the weight of the mixture, and the weight of water It is 10% of the total weight of the mixture and Portland cement. After the mixed material is stirred evenly with a mixer, it is put into a mold and compacted into a block with a size of 11×11×11cm. After 48 hours of natural After curing, the block had a strength of 4.5MP.

Embodiment approach 3

[0014] The metal powder agglomeration technology for steelmaking is to mix the mixture of grinder powder, oxide scale, wire drawing ash and Portland cement with water, wherein the weight of Portland cement is 13% of the weight of the mixture, and the weight of water It is 8.5% of the total weight of the mixture and Portland cement. After the mixed material is stirred evenly with a mixer, it is put into a mold and compacted into a block with a size of 9×9×9cm. After 48 hours of natural After curing, the block has a strength of 5MP.

Abstract

The invention relates to a technology for blocking steelmaking metal powder. The technology for blocking the steelmaking metal powder comprises the following steps: mixing steel metal powder, Portland cement and water, wherein the weight of the Portland cement is 10 to 15 percent of the weight of the steel metal powder and the weight of the water is 7 to 10 percent of the total weight of the steel metal powder and the Portland cement; uniformly stirring the mixed materials by using a stirring machine; placing the mixture into a die and compacting into blocks; naturally curing the blocks for 48 hours. When the steel metal powder is used for smelting, the technology can reduce energy consumption and avoid chemical pollution to the environment.

Description

technical field [0001] The invention relates to the block forming technology of the iron and steel metal powder when the iron and steel metal powder is used for smelting. Background technique [0002] In the smelting industry, metal powders such as steel slag, steel mill powder, grinder powder, scale, and wire drawing ash need to be smelted into steel as raw materials. Blast furnace for smelting steel. For example, the invention patent application with the application number 200810072929.X discloses a process of pressing cast iron shavings into blocks. Water glass glue is used in this process. Because water glass glue will produce chemical pollutants at high temperatures, it will be harmful to the environment. Cause chemical pollution; and the process must use a cupola for smelting, and the cupola will consume a large amount of energy and increase the cost of smelting. Contents of the invention [0003] The object of the present invention is to provide a metal powder blo...
