Abstract
Previously, stainless steel compounding is carried out, and due to cold machining, inevitable existing tiny gaps between stainless steel and a steel product cannot be removed, water steam intrudes from the tiny gaps, and consequently the steel product is rusted and fails. According to a stainless steel plate heat compounding steel plate machining method, steel is casted on the stainless steel plate, and the stainless steel plate covers the casted steel; the tiny gaps between the stainless steel plate and the steel plate are removed, so that the water steam cannot intrude the steel plate covering the stainless steel plate, and rusting of the steel plate is removed; and the steel plate is more tight 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, make steel products get rusty and failure.
The hot clad steel plate processing method of corrosion resistant plate that the prevention steel plate that this technology proposes gets rusty, is called for short hot clad steel plate processing method, can helps above-mentioned Problems existing.
The beneficial effect of hot clad steel plate processing method is, eliminates steel plate and gets rusty, make plate quality better, increases steel plate service time.
Stop the hot clad steel plate processing method of corrosion resistant plate that steel plate gets rusty, the technical scheme that its technical solution problem adopts is, cast steel iron on stainless steel, then covers corrosion resistant plate at cast steel iron; Its technique is, corrosion resistant plate can first draw fine groove, and corrosion resistant plate can first make shallow basin; Corrosion resistant plate or shallow basin (2) is put in mould (1), draw fine frid towards upper, iron and steel is melted slurries and be cast in (3) on corrosion resistant plate or shallow basin, again corrosion resistant plate (4) being covered iron and steel melts on slurries, fine frid is drawn to face down, when the cooling of iron and steel molten slurry becomes soft steel plate, thick template (5) is covered corrosion resistant plate; Thick template pressed by the uniform hydraulic press (6) of available multiway, is depressed into composite plate hardening, to eliminate the gap between steel plate and corrosion resistant plate; Be cast in iron and steel when melting slurries, can vacuumize, melt bubble in slurries to remove iron and steel, make steel plate (7) better quality; After cooling, remove hydraulic press pressure, removing mould, excision exceeds the shallow tub wall in corrosion resistant plate face, polishes cunning, obtain the hot clad steel plate of corrosion resistant plate (8), thus the hot clad steel plate processing method of the corrosion resistant plate that prevention steel plate 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 corrosion resistant plate or shallow basin, iron and steel melts slurries is close to corrosion resistant plate or shallow pelvic surface of sacrum, can not fine clearance be produced, especially under hydraulic press pressure, make steel plate structure more closely better quality on the one hand, another side ensures between corrosion resistant plate and steel plate further, can not fine clearance be produced, make steam cannot invade the steel plate of corrosion resistant plate covering or parcel, thus eliminate steel plate and get rusty; First draw fine groove, iron and steel melts slurries and enters fine groove, makes corrosion resistant plate and steel plate contact surface increase, makes the hot clad steel plate better quality of corrosion resistant plate.It should be noted that a little the pressure of hydraulic press should be followed to increase gradually according to foundry goods softness.With the hydraulic press pressure uniform that multiway is uniform, can ensure that monoblock corrosion resistant plate hot clad steel plate thickness is even.
Figure of description illustrates:
The hot clad steel plate processing method of the corrosion resistant plate that Fig. 1 stops steel plate to get rusty
1 mould, 2 corrosion resistant plates or shallow basin, 3 are cast in, 4 corrosion resistant plates, 5 thick templates, 6 hydraulic presses, 7 steel plates, the hot clad steel plate of 8 corrosion resistant plate.
Claims (1)
1. the hot clad steel plate processing method of corrosion resistant plate stoping steel plate to get rusty, is characterized in that, on stainless steel cast steel iron, then covers corrosion resistant plate at cast steel iron; Its technique is, corrosion resistant plate can first draw fine groove, and corrosion resistant plate can first make shallow basin; In mould, put into corrosion resistant plate or shallow basin, draw fine frid towards upper, iron and steel is melted slurries and be cast on corrosion resistant plate or shallow basin, corrosion resistant plate being covered iron and steel melts on slurries again, draw fine frid to face down, when the cooling of iron and steel molten slurry becomes soft steel plate, thick template is covered corrosion resistant plate; Thick template pressed by the uniform hydraulic press of available multiway, is depressed into composite plate hardening, to eliminate the gap between steel plate and corrosion resistant plate; Be cast in iron and steel when melting slurries, can vacuumize, melt bubble in slurries to remove iron and steel, make plate quality better; After cooling, remove hydraulic press pressure, removing mould, excision exceeds the shallow tub wall in corrosion resistant plate face, polishes cunning, obtain the hot clad steel plate of corrosion resistant plate, thus the hot clad steel plate processing method of the corrosion resistant plate that prevention steel plate is got rusty is run.
