Abstract
The invention discloses an aging furnace for mold steel production. The aging furnace comprises a furnace body and a furnace door, wherein the furnace body is internally provided with a hearth; the hearth is internally provided with a heating device; a hot air circulation channel is arranged on the hearth; two sides of the hearth are communicated with the hot air circulation channel; the hot air circulation channel is internally provided with a positive-negative rotation air blower; a guide track is arranged at the bottom of the hearth; a transportation trolley is arranged on the guide track; the hearth is internally provided with an aluminum silicate refractory fiber blanket lining; rubber asbestos packing is embedded around the furnace opening of the furnace body; and the furnace door is tightly adhered to the rubber asbestos packing of the furnace opening after being closed so as to ensure that no heat is radiated. The aging furnace is simple in structure, convenient to operate, good in ventilation circulation heat preservation property, capable of controlling the temperature inside the hearth on site, and improves the quality in aging treatment on mold steel.
Description
Technical field
The present invention relates to a kind of aging oven, relate in particular to a kind of aging oven of producing for die steel, belong to die steel production unit technical field.
Background technology
Ageing treatment: refer to that alloy workpiece is through solution treatment, cold plastic deformation or casting, after forging, keep its performance, shape, the thermal treatment process of size time to time change in higher temperature placement or room temperature.If adopt workpiece is heated to comparatively high temps, and the short period carry out the aging treatment process of ageing treatment, be called artificial aging processing, the aging phenomenon occurring if workpiece is placed on to long storage time under room temperature or natural condition, is called natural aging treatment.The object of ageing treatment, the internal stress of elimination workpiece, stabilizing tissue and size, improve mechanical property etc.
Existing aging oven is mainly used in various alloys, comprise the low-temperaturetempering timeliness operation of high chromium steel, die steel and other special steel, elimination precision measuringtoll or mould, part size, shape in life-time service change, be everlasting after low-temperaturetempering before (low tempering temperatures 150-250 ℃) precision work, workpiece is reheated to 100-150 ℃, keep 5-20 hour, steel member under low temperature or moving load condition is carried out to ageing treatment, to eliminate unrelieved stress, stablize steel tissue and size, particularly important.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, a kind of aging oven of producing for die steel is provided, this aging oven is simple in structure, easy to operate, and ventilating and thermal insulating performance is good, has improved the quality to die steel ageing treatment.
Technical scheme: a kind of aging oven of producing for die steel of the present invention, comprise body of heater and fire door, in described body of heater, be provided with burner hearth, described burner hearth inner heating device, described burner hearth is provided with hot air circulation passage, the both sides of described burner hearth are connected with hot air circulation passage, in described hot air circulation passage, be provided with rotating blower, the bottom of described burner hearth is provided with guide rail, described guide rail is provided with transport trolley, in described burner hearth, be provided with aluminosilicate refractory fiber pin and needle liner, the fire door surrounding of described body of heater is embedded with rubber asbestos packing, the rubber asbestos packing that fire door is closed rear and fire door is adjacent to, guarantee that empty calory distributes.
Further, described heating unit is tubular rheostat well heater, is arranged on burner hearth both sides and chassis face.
Further, described aging oven is also provided with temperature control system, and as preferably, described temperature control system adopts temperature PID to regulate and controls.
Further improve technique scheme, in described burner hearth, be provided with wind guide tank, air deflector and windsheild, air deflector is arranged on roof of the furnace, is connected with wind guide tank, when opening after blower, wind throws away in blower, blows to equably on the heating unit of burner hearth both sides successively through wind guide tank and air deflector, blows in burner hearth through the ventilation opening of windsheild bottom, suck again in blower, circulation and so forth, the heat that heating unit is produced is brought in burner hearth, and workpiece is heated evenly.
Compared with prior art, its beneficial effect is in the present invention: the aging oven of producing for die steel of the present invention, and this aging oven is simple in structure, easy to operate, circulation good heat insulating, can carry out field control to the temperature in burner hearth, has improved the quality to die steel ageing treatment.
