產(chǎn)品概述

Ceramic Foam Filtration-Silicon Carbide Type

Scope of application：

Suitable for ductile iron, gray iron and copper alloy casting

Product function

1. Filter slag to reduce the harm of slag to casting.

2. Filter out bubbles in liquid metal.

3. Rectification, make the flow of liquid metal from turbulence to laminar flow, reduce the secondary oxidation and air suction of liquid metal, and improve the casting performance.

Precautions

1. The closer the position is to the casting cavity, the better it is to reduce the probability of secondary oxidation;

2. It is better to design the gating system simply without considering other slag retaining measures, which can improve the utilization rate of sand mold and process yield;

3. The working area of the filter should be 4 ~ 6 times of the flow resistance section of the gating system to ensure that the pouring speed is not affected;

4. The filter should be selected according to the type of casting alloy and pouring temperature, and should not be used over temperature;

5. Select the appropriate pore size to achieve the filtering effect;

6. The pouring speed cannot be controlled by filter.

Product performance index:

Tolerance temperature (℃): ≤ 1500

Through hole rate (%): ≥ 80
