Abstract
The utility model in particular relates to a stainless steel clad plate water cooling device and solves the problems of an existing stainless steel clad plate subjected to heat treatment that the corrosion resistance is poor and the use performances are affected due to easy stripping. The water cooling device comprises a base arranged in a hearth, upper and lower thermocouples which are positioned on upper and lower sides of the hearth and are fixed on the hearth, as well as a water inlet pipe and a water outlet pipe which penetrate through the upper wall of the hearth, wherein resistor wires are fixed on the inner walls of the hearth and the base; gasket iron is arranged on the base; a red copper corrugated pipe which is communicated with the water inlet pipe and the water outlet pipe and is positioned in the hearth is arranged above the gasket iron; a water tank is connected with the outer ends of the water inlet pipe and the water outlet pipe; a water pump connected with the water inlet pipe is arranged in the water tank; and a flow meter and a valve are arranged on the water inlet pipe. According to the water cooling device, a clad layer side and a base layer side have similar expansion and contraction, a stainless steel side can avoid a sensitization temperature interval, the growth trend of austenite grains is reduced, and the corrosion resistance is improved.
Description
Technical field
The utility model relates to stainless compound steel plate apparatus for heat-treatment, is specially a kind of stainless compound steel plate water cooling plant.
Background technology
China originates in early 1960s to the development of explosive welding composite metal plate.In recent years along with the industrial expansion such as China's oil and chemical industry, for economizing on resources and adapting to high temperature, high pressure, the bad working environments such as inflammable, explosive, poisonous, increasing petrochemical equipment adopts stainless steel and nonferrous materials.Making great efforts down for many years of multi-disciplinary research personnel at home and abroad, manufacture and the use of Explosive Welding Composite Plates reach its maturity, the thermal treatment process that this just need to match.
There is strong viscous deformation near basic unit stainless compound steel plate recombination region with multiple layer, and tissue is streamline feature, and basic unit's one side crystal grain significantly elongates, and multiple layer one side is because deformed grains internal stress is large, and dislocation desity is large; And the intensity of the compound rear material that explodes significantly increases, plasticity, toughness drop, can not meet in equipment making that composite board material shapes and composite board equipment moves needed plasticity and toughness reguirements; In addition, in blast recombination process, also there is larger machining stress.These all need to improve or the performance of restorer by corresponding thermal treatment, make it reach the requirement of use.
The basic unit of stainless compound steel plate and the physicals of coating have very big-difference, and this has just determined after conventional thermal treatment, and coating and basic unit experience after identical thermal cycling, still have very large unrelieved stress at the interface of coating and basic unit; And clad steel plate heat-treats by basic unit's thermal treatment process, long in the interval residence time of stainless steel sensitizing temperature, its erosion resistance may be reduced, and stainless steel one side grain growth may be made; And composite bed in conjunction with a little less than, may occur hot soarfing from.
Summary of the invention
There is corrosion-resistant and easily peel off the problem that affects its use properties in the utility model, a kind of stainless compound steel plate water cooling plant is provided after solving existing stainless compound steel plate thermal treatment.
The utility model is to adopt following technical scheme to realize: stainless compound steel plate water cooling plant, comprise the base being provided with in burner hearth, the upper thermopair and the lower thermopair that are positioned at the upper and lower both sides of burner hearth and fix with burner hearth, be through water inlet pipe and the rising pipe of burner hearth upper wall, burner hearth and base inner wall are all fixed with resistance wire, and on base, be provided with parallels, parallels top is provided with the red copper corrugated tube that is communicated with and is positioned at burner hearth with water inlet pipe and rising pipe, the outer end of water inlet pipe and rising pipe is connected with water tank, in water tank, be provided with the water pump being connected with water inlet pipe, on water inlet pipe, be provided with under meter and valve.
Adopt red copper corrugated tube to make the water cooling tube of water cooling plant for adapting to the pattern of distinct device, under meter is used for monitoring for the speed feeding water, reach and control coating thermal treatment heat-up rate, cooling rate and heat treated top temperature, make coating one side and basic unit's one side have close Swelling and contraction amount, and can make stainless steel one side can avoid sensitizing temperature interval, reduce the tendency of Austenite Grain Growth, ensured the performance of stainless compound steel plate; Thermopair is monitored the temperature of clad surface in real time.After having overcome existing stainless compound steel plate thermal treatment, there is corrosion-resistant and easily peel off the problem that affects its use properties.
The utility model reasonable in design is reliable, by preparing water cooling plant, conventional heat treatment furnace is improved, to control the stainless heat-up rate of coating, cooling rate and heat treated holding temperature, make coating one side and basic unit's one side have close Swelling and contraction amount, and can make stainless steel one side can avoid sensitizing temperature interval, reduce the tendency of Austenite Grain Growth, raising erosion resistance, has advantages of simple in structure, easy to process and cost is low.
