Abstract
The invention relates to a stainless steel blind plate. The stainless steel blind plate is characterized in that A356/357 stainless steel is adopted, a metal semi-solid alloy is prepared, a blank with the needed dimensional length is cut according to calculation, then the blank is heated and controlled to a proper temperature, the blank is automatically carried to a metal injection port in the upper part of a pressing machine die, and the blank enters a press-injection barrel, and then is subjected to rolling and heat treatment, and pressed-formed by virtue of an oil pressure piston. The stainless steel blind plate disclosed by the invention has the characteristics of being low in stainless steel, excellent in corrosion resistance and ductility, high in specific strength, low in production cost, high in comprehensive mechanical property, and resistant to wear, corrosion and high temperature.
Description
Technical field
The invention belongs to mechanical field, a kind of rustless steel blind plate.
Background technology
Blind plate is that, for sealing pipe stopper, it is the same to act on welding end socket and screwed pipe cap, only blind plate method
Blue and screwed pipe cap can be unloaded down at any time, and it is then not all right to weld end socket.The form species of sealing surface is more, have plane,
Convex surface, male and fomale(M＆F), tongue and groove, ring joint face.
The content of the invention
The purpose of the present invention is aiming at the defect of prior art presence, invents a kind of rustless steel blind plate, it is characterised in that：
Using A356/357 rustless steels, by the preparation of metal semi-solid alloy, according to calculating, the base of required size length is cut
Material, reheats and controls appropriate temperature, the metal injection mouth of automatic transporting to die of press top, into injection
After cylinder, roll and heat treatment, use hydraulic piston press molding.
It is characteristic of the invention that：Stainless density is little, there is excellent corrosion resistance and ductility, and specific strength is high, produces cost
It is low；Comprehensive mechanical property, wear resistance and corrosion resistance, high temperature resistant.
Specific embodiment
A kind of rustless steel blind plate, it is characterised in that：Using A356/357 rustless steels, by the system of metal semi-solid alloy
It is standby, according to calculating, the blank of required size length is cut, appropriate temperature is reheated and controls, automatic transporting is extremely
The metal injection mouth on die of press top, into after injection cylinder, rolls and heat treatment, uses hydraulic piston press molding.
In order to ensure that new type stainless steel. corrosion resistance has good corrosion resistance, its heat treatment adopts solution treatment so as to carbide
Can be solid-solution in greatest extent in matrix with intermetallic phase.For this purpose, test steel adopts 1050 DEG C × 2h water-cooled solution treatment.
650 DEG C × 2h air cooling sensitized treatments have been carried out after solution treatment again so as to the carbide and gold in steel at this temperature
Mutually fully separate out between category, to ensure its result of the test for the reliability in actual production.Testing Heat-Treatment of Steel is
Carry out in box temperature automatically controlled electric furnace.
In addition, the present invention has been shown and described embodiment, for the ordinary skill in the art, can be with
Understanding these embodiments can be carried out without departing from the principles and spirit of the present invention various changes, modification,
Replace and modification, the scope of the present invention be defined by the appended.
