Qingdao Hexin Machinery uses resin sand technology and automatic production equipment, it can realize automatic sand distribution, sand filling, molding, hardening, demoulding and sand regeneration, and can continuously produce casting heat transfer plates with high efficiency and stable quality.

High production efficiency, stable casting quality, high surface quality, uniform and dense internal structure, no blisters, slag inclusions, pores, cracks and other defects. Can guarantee product quality and long service life.

 

Structural features

a) The double-sided fin cast plate air preheater is composed of multiple cast heat transfer fins in different ways to form a single-pass or multi-pass whole;

b) Each cast heat transfer plate is cast, and the plates are connected by bolts;

c) Double-sided fin casting The single heat transfer fin of the plate air preheater is made of pre-made steel abrasives, and the double-sided finned heat transfer plate is a one-time integral casting, which can ensure the integrity of the airtightness.

d) Compact structure and small footprint;

e) Modular structure, suitable for assembly and transportation.

3. Thermal properties

a) The heat transfer coefficient is high, and the general tube bundle air preheater cannot be compared with the heat pipe air preheater;

b) Good air tightness;

c) Under the same operating conditions, the cast air preheater has a longer life than the carbon steel air preheater.
