[0002] The production of the traditional walking wheel adopts the old-fashioned casting method, using the cupola as the raw material melter, and the casting mold relies on manual modeling. The burning of fuel in the cupola not only consumes a lot of resources, is inefficient, but also produces a lot of environmental pollution; the manual casting of the mold Modeling, resulting in rough product surface and low precision, especially the inner surface of the product; the overall process production speed is slow, the yield is low, resulting in high product cost

Embodiment 1

[0027] A production method of a running wheel, which sequentially comprises the following production steps:

[0028] (1) After adding the iron-containing raw materials into the intermediate frequency electric furnace, the iron-containing raw materials are heated to melt the iron-containing raw materials into molten iron. The iron-containing raw materials include pig iron, scrap steel, recycled materials, and ferrosilicon and ferromanganese, pig iron is an iron-carbon alloy with a carbon content between 2% and 4.3%, scrap steel is a variety of steel products recycled, and returned materials are defective products and waste products produced. Ferrosilicon and ferromanganese are respectively silicon-containing Iron alloy with manganese to adjust the content of silicon and manganese in the product;

[0029] (2) Put the spheroidizing agent and alloy raw materials into the ladle, the nodulizing agent is ReMg3-8, the alloy raw materials are copper and magnesium, and magnesium also ha...

Abstract

The invention discloses a method for producing a traveling wheel, which comprises the following steps: putting an iron-containing raw material into a middle frequency furnace and heating the iron-containing raw material; melting the iron-containing raw material into molten iron; reacting the molten iron with a nodulizer and an alloy raw material to obtain a molten alloy; making a sand-lined metalmould with cast iron; and injecting the molten alloy to the sand-lined metal mould. The inventor controls the working temperature of a product, the casting temperature and the casting speed of the alloy, the standing time of a cast product in the mould strictly after long term grope and adopts the breakthrough sand-lined metal mould for casting so as to solve the technical problems of poor dimensional precision and low finished product ratio of a long-term used green sand hand-made mould in the field.

Description

technical field [0001] The invention relates to a production method, in particular to a production method of a running wheel. Background technique [0002] The production of the traditional walking wheel adopts the old-fashioned casting method, using the cupola as the raw material melter, and the casting mold relies on manual modeling. The burning of fuel in the cupola not only consumes a lot of resources, is inefficient, but also produces a lot of environmental pollution; the manual casting of the mold The shape of the product results in rough surface and low precision, especially the inner surface of the product; the overall process production speed is slow and the yield is low, resulting in high product cost. Contents of the invention [0003] The purpose of the present invention is to provide a production method of a wheel with high yield, fine product surface and high production efficiency. [0004] Above-mentioned technical purpose of the present invention is achiev...
