Embodiment

[0012] In a titanium sponge production plant, titanium sponge is produced by combined magnesium reduction distillation method. As attached picture 1, figure 2 As shown, the well-type electric heating furnace has a furnace bottom and a furnace wall. The well-type electric heating furnace is equipped with 12 air inlets 1 evenly distributed in the middle of the heating furnace wall, and 6 air exhaust outlets are evenly distributed on the upper part of the heating furnace wall. 2. The air outlet 2 has a length vertically upward after being released from the furnace, and the furnace wall of the heating furnace is also provided with an evacuation port 3; as shown in Figure 3, the furnace wall of the well-type electric heating furnace is the furnace shell 4 from the outside to the inside. , furnace lining and electric heating body, furnace lining is made up of refractory brick 7, insulation layer, heat insulation layer, and electric heating body is that resistance wire is installed o...

Abstract

The unitedly produced titanium sponge electric heater is well type electric heater with the heater is made of a housing, a brasque and an electric heating device. The brasque is composed of firebrick, heat reserving layer and heat insulating layer, with the electric heater a resistance wire loaded on the wire resting brick, featuring in the heat insulating layer made of rock wool board (5), heat reserving layer of bulking vermiculite, having at least 8 wind inlets (1) evenly set at the center of the hearth of the heater. At least four wind outlets (2) are envenly arranged on the top of the furnace wall, with exhausting openings (3) set on the furnace wall, drawing air from the exhausting opening (3) to keep low vacuum inside the hearth, keeping the reactor (9) not being flat. It has strong radiating ability, improved reacting speed, and fine heat reserving performance, obvious in energy saving with outer wall temperature more than 10DEG C less than existing electric heaters, with a ton of titanium saving energy more than 500Kwh.

Description

technical field [0001] The invention relates to the production of sponge titanium, in particular to a heating furnace for producing sponge titanium by a magnesium method. Background technique [0002] The process of producing sponge titanium by the combined method is to add titanium tetrachloride to the reactor, reduce and distill it with metal magnesium to obtain sponge titanium. The well-type electric heating furnace is a necessary equipment for the reduction distillation process. The reactor is placed in a well-type electric heating furnace for reduction and distillation operations. The well-type electric heating furnace is a mature equipment, but due to the characteristics of the process of producing sponge titanium by the combined method of magnesium reduction and vacuum distillation, the requirements for the well-type electric heating furnace It is obviously different from the general well-type electric heating furnace: it not only requires a certain heating function,...
