摘要： Disclosed is a method for measuring the extent of slag deposit buildup in the channel of a channel induction furnace during operation. The method comprises measuring an initial temperature rise factor in the furnace at a time when no slag deposits are present, measuring a subsequent temperature rise factor in the furnace after the furnace has been in operation for a period of time, correcting the subsequent temperature rise factor for any changes in the operating temperature and power levels applied to the furnace which may have taken place between the time of the measurement of the initial temperature rise factor and the time of the measurement of the subsequent temperature rise factor, and determining a quantity which is indicative of the extent of slag deposit buildup in the channel from the difference between the initial and subsequent temperature rise factors. The temperature rise factor in the furnace is defined as the ratio of the total weight of the molten metal in the furnace to the time required for the temperature of the molten metal to rise by a predetermined amount above the operating temperature of the furnace when the induction heating power applied to the furnace is increased by a specified amount above the operating power level of the furnace.
摘要翻译：公开了一种在操作期间测量通道感应炉的通道中的渣堆积程度的方法。该方法包括在没有渣沉积的情况下测量炉中的初始升温因子，测量在炉已经运行一段时间之后的炉中随后的升温因子，校正随后的升温因子对于在初始温度升高因子的测量时间和随后的升温因子的测量时间之间可能发生的施加到炉子的操作温度和功率水平的任何变化，以及确定表明从初始温度升高和随后升温因子之间的差异，通道中积渣的程度。炉中的升温因子定义为熔炉中的熔融金属的总重量与熔融金属的温度相比上升预定量高于炉的工作温度所需的时间，当感应施加到炉子的加热功率增加高于炉的工作功率水平的指定量。

摘要： A channel furnace for the melting of metals and alloys, of the kind comprising an inductor device for the heating and the unidirectional forced circulation of the molten metal in the channel. The inductor includes a single coil 10 formed of two layers of conductors wound along helices whose axial pitch is equal to the axial length of the coil for one half-turn of winding. The coil is divided into n pairs (n .gtoreq.3) of circuits of m turns each, regularly distributed over the periphery of the coil, the two circuits of each pair being derived one from the other by a rotation of 180.degree. about the axis of the coil and being series-connected together additively from the point of view of the axial component of the magnetic flux which they generate. The pairs are shifted in angle by 2 .pi. /n about the axis of the coil so as to form n phases shifted by 2 .pi. /n.

摘要： A channel-type electric induction heating furnace inductor unit for melting metal, has a metal frame which includes metal side walls having core clearance openings through which a transformer core surrounded by an induction coil extends, the frame supporting refractory forming a channel vertically looping around this core and coil, other core clearance openings being formed through the two walls and the balance of the core extending downwardly outside of these walls and through these other openings to form a closed magnetic flux circuit. Each wall has a gap or slot formed in it and which extends from one opening to the other, the portions of the walls below the core being structurally united or made integral. Since all of the portions of the walls are outside of the core, the formation of eddy currents in the latter are reduced or eliminated. The core is made as two separable parts with one part carrying the induction coil being separable from the furnace and the other core part and the latter comprising a structural part of the frame providing support for the latter.
