Abstract
The invention discloses a crane drum using cast iron. Its technique problem is to offer the crane drum using cast iron. And the formed crane drum has good ware resistance and toughness. Its technical proposal is as follows: it contains silicon, manganese, and carbon; and their contents are respectively 2.0-2.6%, 0.2-0.35%, and 3.0-4.0%; impurity phosphor and sulfur contents are respectively less than 0.25% and 0.1%. The invention can be applied to centrifugal casting crane drum.
Description
Technical field
The present invention relates to a kind of cast iron, particularly a kind of hoist roller cylinder iron.
Background technology
Reel is the vitals of lifting machine, also is a kind of consumption spare part, and its consumption is very big.Present hoist roller adopts sand mold casting production, because sand mold casting, the compactness of material is relatively poor, the requirement of good toughness for the wear resisting property height that reaches reel, silicon in the material, manganese, the content faced there is specific requirement, the sand mold casting reel of this specific component content, is mingled with more seriously at its sand holes, and yield rate is low, the poor-performing of product.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of hoist roller cylinder iron, the hoist roller that this cast iron is made with centrifugal casting technique, and its wear resisting property height and good toughness, the few quality of product defects is good.Technical scheme of the present invention is that a kind of hoist roller cylinder iron contains silicon, manganese, carbon, it is characterized in that: silicone content is 2.0-2.6%, and manganese content is 0.2-0.35%, and carbon content is 3.0-4.0%.The content of impurity p and s is respectively less than 0.25%, 0.1%.The present invention is owing to be adjusted into the silicon in the cast iron, manganese, carbon content respectively: 2.0-2.6%, 0.2-0.35%, 3.0-4.0%, thereby the hoist roller made with centrifugal casting technique of this cast iron has the remarkable advantage of wear resisting property height and good toughness compared with the prior art.
Embodiment
Hoist roller of the present invention cylinder iron, wherein silicone content is 2.0-2.6%, manganese content is 0.2-0.35%, carbon content is 3.0-4.0%, the content of impurity p and s is respectively less than 0.25% and 0.1%.To the stokehold analysis of components of molten iron,, make it meet above-mentioned requirements by adjusting the content of each composition.The hoist roller that uses this cast iron hydromining to make with rotational casting, its wear resisting property height and good toughness.General foundry returns should not surpass 20% when batching, and steel scrap is 10-15%.
Claims (2)
1, a kind of hoist roller cylinder iron contains silicon, manganese, carbon, it is characterized in that: silicone content is 2.0-2.6%, and manganese content is 0.2-0.35%, and carbon content is 3.0-4.0%.
2, a kind of hoist roller according to claim 1 cylinder iron is characterized in that: the content of impurity p and s is respectively less than 0.25%, 0.1%.
