Embodiment 1

[0037] As a preferred embodiment of the cold-pressed pellet production process of the present invention, the manganese content of the ore powder is 36%-40%.

[0038] Mineral powder with a manganese content of 36%-40% is used as an alloy additive to improve the strength, hardness, elastic limit, wear resistance and corrosion resistance of the steel by later pressing; in high alloy steel , It is also used as an austenitic compounding element for refining stainless steel, special alloy steel, stainless steel electrodes, etc.

Embodiment 2

[0040] As a preferred embodiment of the cold-pressed pellet production process of the present invention, the manganese content of dedusting ash is 17%.

[0041] In this embodiment, the dedusting ash is the slag produced after the smelting of the silicon-manganese alloy, and the secondary utilization of the waste material can effectively reduce the cost without affecting the rigidity of the product.

Embodiment 3

[0042] Embodiment 3: As a preferred embodiment of a cold-pressed pellet production process of the present invention, it comprises the following steps:

[0043] Step 1: Select the raw materials of mineral powder and dedusting ash, remove the impurities in the raw materials, and then batch the raw materials according to a certain proportion;

[0044] Step 2: Use the mechanical crushing method to crush and grind the raw materials of mineral powder and dedusting ash for the first time, and then use the ball milling method to carry out secondary crushing on the raw materials, so that the particle fineness of the transported materials can reach the appropriate powder particle fineness for processing;

[0045] Step 3: Use the raw materials prepared on the feeding machine to transport them to the automatic distributing machine. After the distributing machine calculates and measures through the formula parameters, it is put into the buffer bin, and is quantitatively transported to the m...

Abstract

The invention discloses a cold-pressed pellet production process, and relates to the technical field of metal smelting. The cold-pressed pellet production process comprises the following raw materialsin percentages by weight: 60% of mineral powder and 40% of fly ash, and comprises the steps of selecting raw materials for screening out impurities in the raw materials; proportioning the raw materials, namely proportioning the raw materials according to a certain mass ratio; and powder preparation: crushing, grinding and sieving the raw materials. By arranging an automatic distributing machine,a stirring system, a cold pressing main machine and a drying system, a raw material barrel conveyor conveys the raw materials to the automatic distributing machine, the raw materials are pumped into asurge bin after being calculated and metered by the distributing machine according to formula parameters and are quantitatively conveyed to the stirring system through an automatic program, and the stirring system conveys the raw materials to the cold pressing main machine after stirring uniformly; and after the cold pressing main machine automatically completes the pellet pressing process, the raw materials are conveyed to the drying system. According to the technological process, the cold-pressed pellets can be subjected to full-automatic pellet pressing production, the production precisionis high, the efficiency is stable, sustainability and stability are achieved, energy conservation and environmental protection are achieved, and application and popularization can be achieved.

Description

technical field [0001] The invention relates to the technical field of metal smelting, in particular to a cold-pressed pellet production process. Background technique [0002] Cold-pressed pelletizing is a processing process of making finely ground concentrate into a block material that can meet the requirements of smelting pellets, that is, under a certain pressure, the powder material is compressed in the model into a light pellet with a certain shape, size and density. The bulk materials with high density generally need to undergo corresponding consolidation after being formed into agglomerates to make them agglomerates with higher strength. In the process of pellet preparation, the material not only has physical properties (density, porosity, degree, shape, size and mechanical strength, etc.), but also chemical and physical chemical properties (chemical composition, reduction, reduction expansion, low-temperature reduction pulverization performance, high-temperature redu...
