gantry wheels

Product introduction

Material: 42CrMo

Forging wheels for gantry, crane, longer life span and better mechnical capacities

How to solve the technical problem of poor dimensional accuracy and low yield of hand-made molds using tidal sand for a long time in this field?

We have adopted a new production method of walking wheels. After adding the iron-containing raw materials to the intermediate frequency electric furnace, the iron-containing raw materials are heated to melt the iron-containing raw materials into molten iron, and the molten iron is mixed with the molten iron The spheroidizing agent reacts with the alloy raw material to obtain an alloy melt, which is made of cast iron with an iron-type compound sand mold, and the alloy melt is injected into the iron-type compound sand mold. 1. The casting temperature and casting speed of the alloy, the time the casting stays in the mold are strictly controlled, and the iron compound sand mold is used for the breakthrough.


It is characterized in that it includes the following production steps in sequence:    (1) After adding iron-containing raw materials to an intermediate frequency electric furnace, the iron-containing raw materials are heated to melt the iron-containing raw materials into molten iron;    (2) Put the nodulizer and alloy raw materials into the hot metal ladle;    (3) Pour the hot metal obtained in step (1) into the hot metal ladle described in step (2) to make the hot metal and the nodularizer and alloy The raw materials are reacted to obtain the alloy melt;    (4) After the reaction described in step (3) is completed, the garbage and residue floating on the surface of the alloy melt described in step (3) are removed to obtain a clean alloy melt   (5) Make iron mold with cast iron, lay resin sand in the hole of iron mold, fix the resin sand with iron mold, iron mold compound sand mold semi-finished product can be made; then iron mold compound The semi-finished sand mold is put into a heating furnace and heated, and the iron mold is taken out after shaping the resin sand to make an iron composite sand mold;    (6) Inject the clean alloy melt prepared in step (4) into the In the iron-type compound sand mold, the injected clean alloy melt is cooled and formed to form a semi-finished product of a caster, and then the resin sand adhered to the surface of the semi-finished product is removed to make a caster.
