Background technology
The form that net belt type quenches, backfire product line adopts guipure at the uniform velocity to advance is pushed ahead the product on the guipure, upper and lower at guipure is provided with resistance heater, in the body of heater of rectangle, with product from an end of body of heater continuous deliver to the other end, in the product motion process, the resistance heater heating utilizes the product in heat radiation and the heat conduction heating furnace, thereby realizes the heat treatment to product.Most what adopt is the resistance-type meshbeltfurnace at the heating furnace of above-mentioned production line, resistance heater promptly is set in body of heater product is heated, the power consumption of this resistance-type meshbeltfurnace, intensification and temperature fall time are long, and service life is short, and maintenance time is long, expense is high, and the product integrated cost is also high; Clean, drying effect is poor; Consumable accessorys such as guipure, high temperature transmission system part, stove brick, resistance wire, thermocouple need often to change the replacement cost height.In addition, before morning, what the heating furnace of above-mentioned production line adopted is spiral and rotary type cylinder resistance furnace, it is a kind of old-fashioned structure stove, is replaced by the resistance-type meshbeltfurnace substantially in recent decades, and its heating-up time is long, maintenance time is long, the energy consumption height, the life-span is short, and consumable accessorys such as stove brick, resistance wire, thermocouple need often to change.
Summary of the invention
The purpose of this utility model provides a kind of inside spin swinging Medium Frequency Induction Heating Furnace of energy-conservation, quick heating.
It is short that another purpose of the present utility model provides a kind of maintenance time, the mid-frequency induction hardening with inside spin swinging Medium Frequency Induction Heating Furnace of long service life, backfire product line.
In order to achieve the above object, the technical solution of the utility model is: a kind of inside spin swinging Medium Frequency Induction Heating Furnace, comprise helix drum, be equipped with thermal insulation layer in the helix drum outer periphery, thermal insulation layer has heat-insulation layer outward, heat-insulation layer has the Medium frequency induction coil outward, is wrapped with insulation crust at the Medium frequency induction coil.This programme is outside equipped with the Medium frequency induction coil at cylinder, and the electromagnetic field that can utilize the Medium frequency induction coil to produce heats the product in the cylinder, is provided with thermal insulation layer and heat-insulation layer near the cylinder internal layer, and the heat of product can not run off in the cylinder like this.Because the Frequency Induction Heating characteristic factor, thereby it has quick heating, energy-conservation characteristics.
Another technical scheme of the present utility model is: a kind of mid-frequency induction hardening that inside spin swinging Medium Frequency Induction Heating Furnace is housed, backfire product line, be connected with preceding washing barrel between product elevator and the spiral hot-air seasoning stove, above preceding washing barrel, be provided with extraction fan, rear at spiral hot-air seasoning stove is provided with quenching tank, in quenching tank, be connected with the quenching tank elevator, be connected with the back washing barrel between quenching tank elevator and the spiral hot-air seasoning stove, above the washing barrel of back, be provided with extraction fan, be provided with connection and transmission mechanism at the rear of spiral hot-air seasoning stove, be connected with swinging cooling stove between connection and transmission mechanism and the product box, inside spin swinging Medium Frequency Induction Heating Furnace is installed between spiral hot-air seasoning stove and quenching tank, between spiral hot-air seasoning stove and swinging cooling stove, also is connected with inside spin swinging Medium Frequency Induction Heating Furnace.
What the heating furnace in this programme adopted is inside spin swinging Medium Frequency Induction Heating Furnace, has saved consumable accessorys such as guipure, high temperature transmission system, stove brick, resistance heater and thermocouple, so long service life, and maintenance cost is low; In addition, need temperature-gradient method during traditional meshbeltfurnace baker, length consuming time, and cooling is also slow, and this production line is owing to the heating furnace employing is inside spin swinging Medium Frequency Induction Heating Furnace, do not need temperature-gradient method, and because the Frequency Induction Heating characteristic factor, thereby quick heating, it is also fast to lower the temperature, energy-conservation, maintenance time is short.This programme adopts Frequency Induction Heating, induction heat treatment can improve the intensity and the life-span of part, quick heating during eddy-current heating, can obtain crystal grain than refinement, can obtain careful martensitic structure after the quenching, can obtain highly dispersed tempered structure after tempered again, because the invigoration effect of crystal boundary is improved the strength and toughness of part.Therefore, the induction processing can obtain higher-strength and life-span than the part of common heat treatment.
The utility model has the advantages that: energy-conservation, save time, need not baker; Long service life, maintenance cost is low; Heating-cooling is fast, and maintenance time is short; Induction heat treatment can improve the intensity and the life-span of part.
