Influence of different casting systems on casting defect distribution of steel castings
According to the relative position of the internal sprue on the steel casting, the casting system can generally be divided […]

There are two main classification methods for sand casting gating system of mud pump body: one is that it can
The experimental object is Flywheel Casting. The outer circle diameter of the casting is 350mm, the thickness is 39mm, and
The gating system of iron mold sand coated casting is the channel for liquid metal to be injected into the
Gating system (running system) is the general name of the channel of liquid metal flowing into the mold cavity in
Semi closed gating system is adopted, and the proportion is as follows: Σ a inside: ∑ a transverse: ∑ a
The open gating system is adopted, and the proportion is as follows: Within Σ A: ∑A transverse: ∑A straight =
The closed gating system is adopted, and the proportion is as follows: ΣA inside: ∑A transverse: ∑A straight = 1:1.3:1.5
Combined with the production conditions and experience, the casting shrinkage is 1% in length direction, 0.8% in height direction and
According to the above theory, in order to meet the requirements of the sectional area of the sprue, it is
