Abstract
The invention discloses a carbon cast steel tooth blank. The carbon cast steel tooth blank comprises the following components: 0.3-0.4% of C, 0.6-0.8% of Si, 1.1-1.4% of Mn, S not more than 0.03%, P not more than 0.03%, and the balance of Fe. The produced tooth blank has the advantages of high hardness, strong impact resistance, small machining surface, small machining allowance and high metal utilization rate.
Description
Technical field
The invention belongs to tooth base, be specifically related to a kind of carbon cast steel tooth base.
Background technology
Because steel casting teeming temperature is higher than steel ingot, cast shape is complicated, and the control ratio steel ingot of its process of setting is much more difficult, and after this again without forging processing.Generalized case, the crystallization of steel casting is thicker, thermal center place and dendrite to shrinkage porosite be difficult to avoid.Therefore the forged steel pieces that the Performance Ratio composition of cast steel is close is poor.If the technological design of steel casting is better, process of setting controls proper, then gives suitable thermal treatment, then the performance of cast steel is close to forged steel.Carbon cast steel or low-alloy cast steel during current casting tooth base generally adopts, its comprehensive mechanical property is better than other any casting alloys.
Summary of the invention
The object of the invention is to, provide a kind of carbon cast steel tooth base, excellent property.
Carbon cast steel tooth base provided by the invention, its each composition is as follows:
Mn, S of Si, 1.1-1.4% of C, 0.6-0.8% of 0.3-0.4%≤0.03%, P≤0.03%, surplus are Fe.
Carbon cast steel tooth base provided by the invention, its beneficial effect is, the tooth base hardness of production is large, strong shock resistance.Machined surface is little, process redundancy is little, the utilization ratio of metal is high.
Embodiment
Below in conjunction with an embodiment, carbon cast steel tooth base provided by the invention is described in detail.
Embodiment
The carbon cast steel tooth base of the present embodiment, its each composition is as follows:
Mn, S of Si, 1.1-1.4% of C, 0.6-0.8% of 0.3-0.4%≤0.03%, P≤0.03%, surplus are Fe.
Claims (1)
1. a carbon cast steel tooth base, is characterized in that, each composition is as follows:
