Requirements and precautions for surface cleaning of wear - resistant castings

- Jan 26, 2019-

Wear-resistant castings are often made in dusty sites, with a lot of dust in the air, which constantly falls on the surface of equipment.They can be removed with water or an alkaline solution.However, adhesive grime requires high pressure water or steam to clean.

 

1. Surface dust of nodular casting

The production of wear-resisting castings is often carried out in the presence of dust in the air, which constantly falls on the surface of the equipment.They can be removed with water or an alkaline solution.However, adhesive grime requires high pressure water or steam to clean.

2. Surface float iron powder or embedded iron of ductile ink-resistant cast steel

 

Free iron rusts and corrodes stainless steel on any surface.Therefore, the floating powder must be removed and can be removed together with the dust.Some have strong adhesion and must be treated as embedded iron.In addition to dust, surface iron can come from a variety of sources, including cleaning with a plain carbon steel wire brush and shot-peening with sand, glass beads or other abrasives previously used on plain carbon steel, low-alloy steel or cast iron, or grinding previously mentioned non-stainless steel products near stainless steel parts and equipment.If no protective measures are taken against the stainless steel during feeding or hoisting, the iron on the wire rope, spreader and table surface can easily be embedded or defiled.www.wuxiorient.com
