Silicon carbide ceramic foam filter -安徽美程化工有限公司校园招聘简章

Product Introduction

Sic (silicon carbide) ceramic foam filters of OBBO are developed and manufactured for the filtration of cast iron and non ferrous alloys. As the most advanced filter type with the higher filtration efficiency, It can effectively reduce inclusions and turbulence of molten metal, ensuring purified molten metal goes into the mold cavity with improved flow rates.
Using the unique formula and manufacturing process, OBBO sic ceramic foam filters have the excellent thermal shock, chemical and high temperature resistance up to 1500°C.

Function

1.Efficiently filter metal particles impurities such as slag and refractory fragments to the micron level to reduce the loss of tools during machining of castings

2.The molten metal filling is stable and the structure of the casting is uniform, thereby improving the mechanical properties such as surface hardness, tensile strength and fatigue resistance of the casting

3.The three-dimensional mesh structure has a good rectification effect on metal turbulence, and has a good control effect on non-metallic inclusions and secondary oxidation caused by turbulent erosion of the cavity.

4.Simplified gating system and improved cavity utilization

5.The surface of the casting is clean, reducing the machining allowance, shortening the cleaning time, and improving the delivery efficiency
