Abstract
Previously, stainless steel cladding is carried out, and due to cold machining, necessary existing small gaps between stainless steel and a steel product cannot be removed, and water vapour intrudes from the small gaps, and the steel product is rusted and fails. According to the stainless steel tank steel heat composite steel channel machining method for preventing a steel channel from rusting, steel is casted in the hollow wall of a stainless steel channel pipe, the small gaps between the stainless steel channel pipe and the steel channel are removed, and the water vapour cannot intrude into steel angles wrapped by the stainless steel channel pipe, so that rusting of the steel channel is removed, and the steel channel is more compact in structure and better in quality.
Description
The surface of current iron and steel is very easy to get rusty, and all wants painting to prevent surface oxidisation, easily comes off owing to painting, and repeated multiple times painting, and the ability painting that at every turn all will eliminate rust, and rust cleaning makes iron and steel thinning, shortens the service time of steel products.
Also once carried out stainless steel compound in the past, due to be cold working, cannot eliminate the fine clearance certainly existed between stainless steel and steel products, steam is invaded from fine clearance, modern steel products get rusty and failure.
The stainless steel channel-section steel hot compound channel-section steel processing method that the prevention channel-section steel that this technology proposes gets rusty, is called for short hot compound channel-section steel processing method, can helps above-mentioned Problems existing.
The beneficial effect of hot compound channel-section steel processing method is, eliminates channel-section steel and gets rusty, make channel-section steel better quality, increase channel-section steel service time.
Stop the stainless steel channel-section steel hot compound channel-section steel processing method that channel-section steel gets rusty, the technical scheme that its technical solution problem adopts is, cast steel iron in the hollow wall of stainless steel channel-section steel pipe; Its technique is, gets the stainless steel channel-section steel varied in size, and in stainless steel channel-section steel both sides and one end of pulling open a segment distance, weldering corrosion resistant plate, makes stainless steel hollow wall channel-section steel pipe; Stainless steel hollow wall channel-section steel pipe (2) is put in mould (1); Iron and steel being melted slurries (3) is cast in the hollow wall of stainless steel channel-section steel pipe; By stainless steel trough plate (4), pack on the molten slurry of iron and steel in hollow wall; Thick for flute profile template (5) is placed on stainless steel trough plate; When the cooling of iron and steel molten slurry becomes soft channel-section steel, thick template pressed by the uniform hydraulic press (6) of available multiway, is depressed into compound channel-section steel hardening, to eliminate the gap between channel-section steel and stainless steel channel-section steel pipe; Be cast in iron and steel when melting slurries, can vacuumize, melt bubble in slurries to remove iron and steel, make channel-section steel (7) better quality; After cooling, remove hydraulic press pressure, removing mould, excision exceeds channel-section steel wall or the cast steel in corrosion resistant plate face, polish cunning, obtain the hot compound channel-section steel (8) of stainless steel channel-section steel, thus the stainless steel channel-section steel hot compound channel-section steel processing method that prevention channel-section steel is got rusty is run.As Fig. 1
Existing combination principle is introduced:
It is fluids that iron and steel melts slurries, when being cast in stainless steel channel-section steel pipe, iron and steel melts slurries is close to stainless steel channel-section steel tube wall, can not fine clearance be produced, especially under hydraulic press pressure, make the more closely better quality of channel-section steel structure on the one hand, another side ensures between stainless steel channel-section steel pipe and channel-section steel further, can not fine clearance be produced, make steam cannot invade the channel-section steel of stainless steel channel-section steel pipe parcel, thus eliminate channel-section steel and get rusty.It should be noted that a little the pressure of hydraulic press should be followed to increase gradually according to channel-section steel softness.With the hydraulic press pressure uniform that multiway is uniform, can ensure that stainless steel channel-section steel hot compound channel-section steel thickness is even.
Figure of description illustrates:
The stainless steel channel-section steel hot compound channel-section steel processing method that Fig. 1 stops channel-section steel to get rusty
1 mould, 2 stainless steel channel-section steel pipes, 3 iron and steel melt slurries, 4 stainless steel trough plates, the thick template of 5 flute profile, 6 hydraulic presses, 7 channel-section steels, the hot compound channel-section steel of 8 stainless steel channel-section steel.
Claims (1)
1. the stainless steel channel-section steel hot compound channel-section steel processing method stoping channel-section steel to get rusty, is characterized in that, cast steel iron in the hollow wall of stainless steel channel-section steel pipe; Its technique is, gets the stainless steel channel-section steel varied in size, and in stainless steel channel-section steel both sides and one end of pulling open a segment distance, weldering corrosion resistant plate, makes stainless steel hollow wall channel-section steel pipe; Stainless steel hollow wall channel-section steel pipe is put in mould; Iron and steel being melted slurries is cast in the hollow wall of stainless steel channel-section steel pipe; By stainless steel trough plate, pack on the molten slurry of iron and steel in hollow wall; Thick for flute profile template is placed on stainless steel trough plate; When the cooling of iron and steel molten slurry becomes soft channel-section steel, thick template pressed by the uniform hydraulic press of available multiway, is depressed into compound channel-section steel hardening, to eliminate the gap between channel-section steel and stainless steel channel-section steel pipe; Be cast in iron and steel when melting slurries, can vacuumize, melt bubble in slurries to remove iron and steel, make channel-section steel better quality; After cooling, remove hydraulic press pressure, removing mould, excision exceeds channel-section steel wall or the cast steel in corrosion resistant plate face, polishes cunning, obtain the hot compound channel-section steel of stainless steel channel-section steel, thus the stainless steel channel-section steel hot compound channel-section steel processing method that prevention channel-section steel is got rusty is run.
