The steel shot-filled shell core making line (referred to as the shell line) is suitable for the production of sand by the shell type process (ie, using coated sand), and the iron type or dry sand is used as the filling material to support the sand type to complete the casting production. Mainly used to produce high quality castings. The sand type produced by the shell process has the advantages of high strength, good gas permeability and good collapsibility. The castings produced have high geometric precision and dimensional accuracy, which can significantly reduce casting defects of castings, improve the intrinsic quality of castings, and reduce The scrap rate of castings.

Shell line equipment

       The shell line is mainly composed of a step-type casting cooling line unit, a falling sand and a sand-blast separation unit, a steel pellet cooling, a dust removal unit and a shell-type line control system.

(1) Step-type pouring cooling line unit

It is mainly composed of iron filling machine, vibrating table, shell conveyor and open conveying line.

(2) Falling sand and shot sand separation unit

Mainly by the box-turning machine, vibrating falling machine, vibrating conveying sieving machine, bucket hoist, drum screen, linear vibrating fine screen, cooling drum, water spray system, belt conveyor, waste sand storage bucket and various slide tubes Part of the composition.

(3) Iron pellet cooling storage unit

The iron pellet cooling storage unit is mainly composed of an iron pellet cooling device, a chain bucket elevator, a cooling conveyor roller, a water spray control system, an iron pellet storage cooling bucket and the like.

(4) Dust removal unit

The dust removal unit is mainly composed of a dust removal system and a ventilation system. The dust removal system mainly consists of a dust collector, a centrifugal fan, a dust source dust collecting hood, a dust removing pipe and a air volume adjusting gate.

  (5) Control unit

The control unit is mainly composed of a power main switch, a PLC logic control, a manual interface touch screen, and a single switch box.
