The solution heat treatment auxiliary device for an austenitic stainless steel U-shaped pipe comprises a base with a travel wheel, wherein a telescopic branch pipe is fixed on the base; support angle steel is fixed at the upper end of the telescopic branch pipe; a U-shaped connection pipe is fixed at the upper end of the support angle steel; stop valves are arranged at the two end parts on the right side of the U-shaped connection pipe, and the two ends on the right side of the U-shaped connection pipe are connected with an argon source and a compressed gas source respectively; a bevel-type block cap communicated with the U-shaped connection pipe is arranged on the left side of the U-shaped connection pipe. By adopting the device disclosed by the utility model, the working efficiency is improved, the production cost is reduced, and the product quality is effectively guaranteed; the device has the advantages of simple structure, convenience in operation and high safety performance.
Description
Technical field
The utility model relates to Coal Chemical Industry heat treatment auxiliary device, is specially the U-shaped pipe solution heat treatment of a kind of austenitic stainless steel supplementary unit.
Background technology
The U-shaped pipe heat-exchange equipment of austenitic stainless steel is mainly used in the industry such as Coal Chemical Industry, petrochemical complex, large scale development along with Coal Chemical Industry, the raising of product, throughput requirements and extension are produced, and wide market and good opportunity to develop are provided to the manufacture of heat-exchange equipment.
The U-shaped pipe of austenitic stainless steel is after bend pipe; R/D is too small for part bend pipe; pipe bent position crystal grain is elongated greatly; reduced its intergranular corrosion resistance performance and mechanical property, be in use easy to booster, so palpus solution heat treatment; but during solution heat treatment, require protection of inert gas; be incubated rear requirement cooling fast, whole solution heat treatment operability is not strong, wastes time and energy and inefficiency.
Summary of the invention
The utility model exists and wastes time and energy and the problem of inefficiency in order to solve existing U-shaped pipe solution heat treatment, and the U-shaped pipe solution heat treatment of a kind of austenitic stainless steel supplementary unit is provided.
The utility model is to adopt following technical scheme to realize: the U-shaped pipe solution heat treatment of austenitic stainless steel supplementary unit, comprise the base with road wheel, on base, be fixed with flexible arm, flexible arm upper end is fixed with support angle steel, support angle steel upper end and be fixed with U-shaped pipe connecting, the both ends on U-shaped pipe connecting right side are provided with stopping valve, and the two ends on U-shaped pipe connecting right side are connected with respectively argon gas source and compressed gas source, and U-shaped pipe connecting left side is provided with the bevel-type blocking cap being communicated with it.
Carry out before solution heat treatment, the U-shaped pipe pipe bent position of austenitic stainless steel is placed in partial heat treatment stove, cover bell, according to U-shaped pipe specification, bevel-type blocking cap is connected with one end of the U-shaped pipe of austenitic stainless steel, and adopts the U-shaped pipe the other end of bevel-type blocking cap shutoff austenitic stainless steel with holes, then the stopping valve at closes compression air source place, open the stopping valve at argon gas source place, solution treatment is carried out in energising; After thermal treatment insulation, close the stopping valve at argon gas source place, open the stopping valve at compressed air source place, open immediately fire door, carry out cooling fast, complete the solution treatment process of the U-shaped pipe pipe bent position of austenitic stainless steel, overcome existing U-shaped pipe solution heat treatment and existed and waste time and energy and the problem of inefficiency.
Base is to be made by two fixing channel-section steels of intersection; Flexible arm comprises two sleeve pipes that are nested together and distribute up and down, and the outer sleeve sidewall of two sleeve pipe overlappings is fixed with nut, is screwed with the securing bolt contacting with inner sleeve in nut; Between bevel-type blocking cap and U-shaped pipe connecting, be provided with joint, between joint and bevel-type blocking cap, U-shaped pipe connecting, be provided with the nipple joint being connected with both.
During operation, the design of base and flexible manifold configuration, can be according to different structure product, and different heights partial heat treatment stove, all around moves, and adjusts up and down; And taper blocking cap can change according to the specification of U-shaped pipe, highly versatile, saves gas; Stopping valve can timely, effectively be changed gas.
The utility model reasonable in design is reliable, can be for complex structure product and different partial heat treatment stove when the solution heat treatment, connect timely and effectively argon shield, after solution treatment insulation finishes, connect pressurized air and make product cooling fast, avoid austenitic sensitized zone; When having improved working efficiency, reduced production cost, quality product guaranteed effectively, has advantages of simple in structure, easy to operate and safety performance is high.
