# What is Chvorinov's rule in casting?

**Chvorinov's rule**is a mathematical relationship first expressed by Czech engineer Nicolas

**Chvorinov**in 1940, that relates the solidification time for a simple

**casting**to the volume and surface area of the

**casting**.

Herein, what is the relationship known as Chvorinov's rule in casting?

Answer. **Chvorinov's rule** is summarized: TTS= Cm(V/A)2, where TTS= total solidification time, Cm = mold constant, V= volume of **casting**, and A= surface area of **casting**. A chill is a heat sink placed to encourage rapid freezing in certain **casting** regions.

Also Know, what is superheat casting? Pouring temperature refers to the initial temperature of the molten metal used for the **casting** as it is poured into the mold. The difference between the solidification temperature and the pouring temperature of the metal is called the **superheat**.

In respect to this, what is solidification time?

The **solidification time** of a casting is a function of the volume of a casting and its surface area (Chvorinov's rule). **Solidification time** of a casting is given by the formula: Where C is the constant that reflects (a) the mold material, (b) the metal properties (including latent heat), and (c) the temperature.

What are the types of casting?

This technique includes at least four **different** methods: permanent, die, centrifugal, and continuous **casting**.
