Description
Technical field
The utility model belongs to metal material processing apparatus field; provide a kind of heat resistance stainless steel annealing tank; using heat-resisting, anti-oxidant, corrosion resistant stainless steel as material, centrifugal casting moulding, outside surface be coated to the annealing pot of refractory materials protective layer; can be used as the specific equipment of cold-drawn iron wire, hot drawing steel wire, strip anneal technique; also can be used for other and need simultaneously withstand high temperatures, oxidation, exhaust gas corrosion, be particularly in thermal shocking that heating, cooling moves in circles for a long time and bear the special dimension of oxidative attack work condition environment simultaneously.
Background technology
Iron wire, steel wire and steel band are important metal productss, are widely used in production and the construction of every profession and trade, and in its production technique, annealing is indispensable important procedure.Annealing is that metal is slowly heated to certain temperature, keeps enough time, then cools with Reasonable Speed, object removes the unrelieved stress of cold-drawn iron wire, hot drawing steel wire, rolled steel strip, reduce distortion to be inclined to crackle, reduce metal hardness and fragility, improve its plasticity and toughness.In iron wire, steel wire and steel band manufacturing enterprise, most annealing adopts well annealing furnace, and taking up annealing workpiece is packaged type annealing pot.Its workflow is charging---sealed cans---heat---insulation---slow cooling---discharging, flow process about 40 days, maximum operating temperature 850 ~ 900 DEG C.
Portable annealing pot tank body is generally Ф 1000mm, high 2000-2500mm, adopts the thick #25 carbon steel sheet of 18 ~ 20mm to roll inside and outside built-up welding after docking, adopts homogeneity steel plate to be connected with cylindrical shell built-up welding at the bottom of tank.Tank body outside surface carries out the process of infiltration aluminium and forms aluminum oxide film to improve its resistance of oxidation.The working temperature of annealing pot is at the high-temperature area of 850-900 DEG C, iron wire is placed into after in tank and repeatedly heats cooling, the process that annealing pot needs repeatedly to bear heating in generation tank labour, insulation, slow cooling to normal temperature move in circles, thus the material of annealing pot requires to have good anti-oxidant, corrosion resistance, and sufficiently high hot strength and comprehensive mechanical performance.For a long time, original, butt seam good with carbon steel sheet circle weld, the annealing pot of aluminising formation, because of anti-oxidant, resistance to corrosion is poor, in working long hours under the condition of high temperature causing annealing pot to move in circles in heating, cooling, heating, cooling, too early oxidation, peeling, decortication, weld cracking, tank body bears weight comparatively greatly, the problems such as tank body is easily out of shape in lifting moving process.
The principal mode of its broken invalid is: 1) surface alumina oxide breakage of thin film applied, matrix carbon steel is subject to the oxidative attack of inner flue gas of the stove, produce spot corrosion even to degrade, make after eating thrown tank body that the annealing workpiece in tank is oxidated to be scrapped, annealing pot and internal workpiece thereof is caused to be no more than 1 year work-ing life, and after using for some time, superficial oxidation is serious, it is also unwelcome for carrying out processing as waste product iron; 2) tank body oxidated after deteriorate and make the weldering body of built-up welding and the decohesion of tank body, tank body air leakage failure; 3) the plain carbon stool heat resistanceheat resistant that tank body adopts is shaken poor-performing, and heat-resistant anti-fatigue performance is not enough, easily produces distortion and lost efficacy in using.Finally not only make product short for work-ing life, safety coefficient is low, causes production cost to remain high, and have impact on the economic benefit of user greatly.
Summary of the invention
, easily there is the problem of broken invalid, provide a kind of heat resistance stainless steel annealing tank in the process that the utility model bears heating repeatedly in order to solve during current portable annealing pot uses, insulation, slow cooling to normal temperature move in circles.
