Abstract

The utility model relates to a low-frequency channel-type induction furnace for Zn-Al alloy. A plurality of soup tank bottoms are provided with communicated W-shaped diversion channels. Two side channels of the diversion channels are provided with a silicon steel column across a center channel, and the silicon steel column is winded on a low-frequency coil. The magnetic contact area generated form the heating metal low frequency coil in a furnace can increase effectively through the distributing diversion channels on the circumference of the low frequency coil. Molten metal in the furnace can generate convection effect through the characteristic of the W-shaped diversion channel. The efficiency of heating efficiency is increased to heat metals on each part in the furnace more uniformly and ensure alloy processing quality.

Description

The low frequency ditch type sense melt furnace of allumen

The utility model is the low frequency ditch type sense melt furnace structure of relevant zinc-aluminium gold, be meant a kind of especially by W water conservancy diversion channel design, can strengthen the magnetic width of cloth contact area of interior metal of stove and low-frequency coil, and the convection current that utilizes motlten metal in the water conservancy diversion raceway groove makes its homogeneous heating, quick, with the efficient of enhancement fusion and the quality of alloy.

Common allumen low frequency induction furnace construction, it is the bottom side of directly being located at molten hot water bathing pool in body of heater with the silicon steel band of column that twines low-frequency coil, the low frequency magnetic width of cloth that this low-frequency coil energising back produces is by the metal in the molten hot water bathing pool, make it generation and add thermal effect, and then reach the function of insulation or fusion.Yet, the low frequency induction smelting furnace of this kind structure, it is because low-frequency coil is the bottom side that is arranged at molten hot water bathing pool, and the magnetic width of cloth that this low-frequency coil exhaled also weakens with the increase of distance, therefore, the METAL HEATING PROCESS effect of top is relatively poor in the molten hot water bathing pool, adds that the furnace inner space design is difficult for having the motlten metal convection current, easily produces the uneven situation of heating, this the lighter can cause prolong heat time heating time, reduce operating power, weight person then has the metallic crystal variation to differ, and influences the quality of alloy finished product.

The utility model purpose aims to provide a kind of low frequency ditch type sense melt furnace of allumen, it is provided with a plurality of soup-dissolving pools in the body of heater top, this a plurality of soup-dissolving pools bottom side is provided with the water conservancy diversion raceway groove that is connected and is W shape, provide the silicon steel post that twines low-frequency coil in this water conservancy diversion raceway groove, because this water conservancy diversion raceway groove is laid in the characteristic of low-frequency coil week side, can effectively increase metal and low-frequency coil generation magnetic width of cloth contact area in the stove, and utilize the design of W shape water conservancy diversion raceway groove, can make the motlten metal in it produce convection action, the effect of promoting the efficiency of heating surface is not only arranged, more can make interior each METAL HEATING PROCESS of stove even, guarantee the metallic crystal quality, this is a main purpose of the present utility model.

As for detailed construction of the present utility model, application principle, effect and effect, the then explanation of doing with reference to following adjoint, can be understood completely:

Fig. 1 is a structure decomposition map of the present utility model.

Fig. 2 is the utility model stereo appearance figure.

Fig. 3 is the utility model overall structure profile.

Fig. 1 is the utility model structure decomposition map, shown in this figure, can find out clearly that the utility model mainly comprises: body of heater 1, low-frequency coil 2, cooling jacket 3 and bell 4 etc. are partly; Wherein this body of heater 1 is when making, its inside is inserted a bell 13 that is W shape in advance, make and in body of heater 1, form one after its moulding and have central raceway groove 111 is communicated with lateral sulcus road 112 with two sides complete water conservancy diversion raceway groove 11, body of heater 1 then laterally provides a plurality of ducts 12 in the

central raceway groove

111 and 112 in the two lateral sulcus roads of water conservancy diversion raceway groove 11, low-frequency coil 2 is that the silicon steel post 21 2 that is wound in a n shape protrudes position week side, cooling jacket 3 is internal diameter central cannulation greater than low-frequency coil 2, its periphery ring is laid with water pipe 31, bell 4 is to be covered on body of heater 1 top, is provided with at least two soup-dissolving pools 41 in it.

Fig. 2, Fig. 3 is the utility model stereo appearance figure and section of structure, can find out by this two diagram, this cooling jacket 3 is after being sleeved on low-frequency coil 2 outer circumferential sides, fill in again in the duct 12 of body of heater 1, low-frequency coil 2 then can utilize silicon steel post 21 that the low frequency magnetic that produces is complete and exhale equably, make metal induction back in all side water conservancy diversion raceway grooves 11 produce heat and fuse, because the distribution of this water conservancy diversion raceway groove 11 is all sides around low-frequency coil 2, thereby the metal in it can fill part and low frequency magnetic width of cloth contact induction, increase its firing rate and efficient, in addition the low frequency magnetic width of cloth drives central raceway groove 111 and lateral sulcus road 112 convection current of metal in water conservancy diversion raceway groove 11 in and moves, conduction and the temperature that can promote heat are even, bell 4 is to be arranged at body of heater 1 top, 41 of soup-dissolving pools in it are communicated with two lateral sulcus roads, 112 top ends of water conservancy diversion raceway groove 11 respectively, for taking motlten metal, aforementioned cooling jacket 3 then is the temperature that is used to cool off low-frequency coil 2, avoids low-frequency coil 2 to burn because of high temperature.

The utility model is because the metal in the water conservancy diversion raceway groove 11 can fill part and low frequency magnetic width of cloth contact induction, and the low frequency magnetic width of cloth also can drive metal and move in 112 convection current of central raceway groove 111 and lateral sulcus road, so can effectively promote the efficiency of heating surface, reduce warm-up time, more can make each metal temperature even, for reducing cost and improving the quality the aspect, great effect is arranged.

From the above, the low frequency ditch type sense melt furnace of allumen of the present utility model has effects such as promote heating power, reduce warm-up time, METAL HEATING PROCESS is even really.
